MySQL: Access denied for user 'userName'#'localhost'

MySQL: Access denied for user 'userName'#'localhost' - java

I am having an issue with creating and grating permissions to a user using phpMyAdmin. I am having a Java swing application and it need to connect to this database.
How I created the user and granted the permission are below, step by step.
Open phpMyAdmin
Go to 'Users' tab.
Click on Add New User
Give the user name, select Any Host as the host (so the % is displayed in its text box), and mention the password. Any host is because remote access required.
Select Select under Global Privileges - Data
Click on Go
Now I am in the Users tab starting page again.
Click on Edit Privileges on my newly created user.
Select the database under Database-specific privileges
Tick everything under Database-specific privileges, Data section.
Click on Go
Now, whenever my Java application connects to this, it gives the below error
java.sql.SQLException: Access denied for user 'userName'#'localhost' (using password: YES)
This is how I connect to the database, in my Java application
con = DriverManager.getConnection("jdbc:mysql://"+ip+":3306/databaseName","user","password");
Here,for the variable ip, I tried both localhost and 127.0.0.1 but still no good. What have I done wrong?
I noticed the connection works fine if I select Localhost instead of Any Host in step 4.

After you have made your user.
Click edit priviliges.
Change Any Host for Localhost.
Apply your priviliges.
Scroll to the bottom and
make sure that "keep old one" is selected and press Go.

You need to grant permissions to the userName#localhost in mysql.
GRANT ALL PRIVILEGES ON database_name TO userName#localhost IDENTIFIED BY 'password';
FLUSH PRIVILEGES;

sometimes, mysql server doesn't get a 'localhost' from a local connection, you should try :
GRANT ALL PRIVILEGES ON database_name TO 'userName'#'theHostName' IDENTIFIED BY 'password';
or in a more risky way:
GRANT ALL PRIVILEGES ON database_name TO 'userName'#'%' IDENTIFIED BY 'password';
and finally
FLUSH PRIVILEGES;

Have you set any password for the phpmyadmin. if yes please include that in the password field.or you can try lik this
con = DriverManager.getConnection("jdbc:mysql://"+ip+":3306/databaseName","localhost","");

Access denied for user 'root'#'localhost' (using password: YES) on other computers [duplicate]

Tried
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
Getting
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'IDENTIFIED BY 'root' WITH GRANT OPTION' at line 1.
Note: The same is working when tried in previous versions.
Also tried
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
Getting
ERROR 1410 (42000): You are not allowed to create a user with GRANT
MySQL (8.0.11.0) username/password is root/root.

Starting with MySQL 8 you no longer can (implicitly) create a user using the GRANT command. Use CREATE USER instead, followed by the GRANT statement:
mysql> CREATE USER 'root'#'%' IDENTIFIED BY 'PASSWORD';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
Caution about the security risks about WITH GRANT OPTION, see:
Grant all privileges on database

I see a lot of (wrong) answers, it is just as simple as this:
USE mysql;
CREATE USER 'user'#'localhost' IDENTIFIED BY 'P#ssW0rd';
GRANT ALL ON *.* TO 'user'#'localhost';
FLUSH PRIVILEGES;
Note: instead of a self-created user you can use root to connect to the database. However, using the default root account to let an application connect to the database is not the preferred way. Alternative privileges can be applied as follows (be careful and remember the least-privilege principle):
-- Grant user permissions to all tables in my_database from localhost --
GRANT ALL ON my_database.* TO 'user'#'localhost';
-- Grant user permissions to my_table in my_database from localhost --
GRANT ALL ON my_database.my_table TO 'user'#'localhost';
-- Grant user permissions to all tables and databases from all hosts --
GRANT ALL ON *.* TO 'user'#'*';
If you would somehow run into the following error:
ERROR 1130 (HY000): Host ‘1.2.3.4’ is not allowed to connect to this
MySQL server
You need add/change the following two lines in /etc/mysql/my.cnf and restart mysql:
bind-address = 0.0.0.0
skip-networking
You could run into the following error, which is a bit confusing:
ERROR 1410 (42000): You are not allowed to create a user with GRANT
This means that either the user does not exist at all OR that the user#host combination does not exist. You can easily check for this with the following command:
SELECT host, user FROM user

1) This worked for me. First, create a new user. Example: User foo with password bar
> mysql> CREATE USER 'foo'#'localhost' IDENTIFIED WITH mysql_native_password BY 'bar';
2) Replace the below code with a username with 'foo'.
> mysql> GRANT ALL PRIVILEGES ON database_name.* TO'foo'#'localhost';
Note: database_name is the database that you want to have privileges, . means all on all
3) Login as user foo
mysql> mysql -u foo -p
Password: bar
4) Make sure your initial connection from Sequelize is set to foo with pw bar.

Just my 2 cents on the subject. I was having the exact same issue with trying to connect from MySQL Workbench. I'm running a bitnami-mysql virtual machine to set up a local sandbox for development.
Bitnami's tutorial said to run the 'Grant All Privileges' command:
/opt/bitnami/mysql/bin/mysql -u root -p -e "grant all privileges on *.* to 'root'#'%' identified by 'PASSWORD' with grant option";
This was clearly not working, I finally got it to work using Mike Lischke's answer.
What I think happened was that the root#% user had the wrong credentials associated to it. So if you've tried to modify the user's privileges and with no luck try:
Dropping the user.
Create the user again.
Make sure you have the correct binding on your MySQL config file.
In my case I've commented the line out since it's just for a sandbox environment.
1. Dropping the user.
From Mysql Console:
List Users (helpful to see all your users):
select user, host from mysql.user;
Drop Desired User:
drop user '{{ username }}'#'%';
2. Create the user again.
Create User and Grant Permissions:
CREATE USER '{{ username }}'#'%' IDENTIFIED BY '{{ password }}';
GRANT ALL PRIVILEGES ON *.* TO '{{ username }}'#'%' WITH GRANT OPTION;
Run this command:
FLUSH PRIVILEGES;
3. Make sure you have the correct binding on your MySQL config file.
Locate your MySQL config file (additional notes at the end). If you want to have MySQL listen for connections on more than one network find the following line on the config file:
bind-address=127.0.0.1
and comment it using a '#':
#bind-address=127.0.0.1
For production environments you might want to use limit the network access (additional notes at the end).
Then restart your MySQL service.
Hope this helps someone having the same issue!
Binding: If you want to know more about this I suggest looking at the following
solution How to bind MySQL server to more than one IP address. It
basically says you can leave MySQL open and limit connections by using
a firewall, or natively if you have MySQL version 8.0.13 and above.
MySQL Config File The file could have different locations depending on your
Linux distribution and installation. On my system it was located at
'/etc/my.cnf'. Here are other suggested locations:
/etc/mysql/mysql.conf.d
/etc/mysql/my.cnf
You can also search for the config locations as shown in this website:
How to find locations of MySQL config files.

For those who've been confused by CREATE USER 'root'#'localhost' when you already have a root account on the server machine, keep in mind that your 'root'#'localhost' and 'root'#'your_remote_ip' are two different users (same user name, yet different scope) in mysql server. Hence, creating a new user with your_remote_ip postfix will actually create a new valid root user that you can use to access the mysql server from a remote machine.
For example, if you're using root to connect to your mysql server from a remote machine whose IP is 10.154.10.241 and you want to set a password for the remote root account which is 'Abcdef123!##', here are steps you would want to follow:
On your mysql server machine, do mysql -u root -p, then enter your password for root to login.
Once in mysql> session, do this to create root user for the remote scope:
mysql> CREATE USER 'root'#'10.154.10.241' IDENTIFIED BY 'Abcdef123!##';
After the Query OK message, do this to grant the newly created root user all privileges:
mysql> GRANT ALL ON *.* TO 'root'#'10.154.10.241';
And then:
FLUSH PRIVILEGES;
Restart the mysqld service:
sudo service mysqld restart
Confirm that the server has successfully restarted:
sudo service mysqld status
If the steps above were executed without any error, you can now access to the mysql server from a remote machine using root.

My Specs:
mysql --version
mysql Ver 8.0.16 for Linux on x86_64 (MySQL Community Server - GPL)
What worked for me:
mysql> CREATE USER 'username'#'localhost' IDENTIFIED BY 'desired_password';
mysql> GRANT ALL PRIVILEGES ON db_name.* TO 'username'#'localhost' WITH GRANT OPTION;
Response in both queries:
Query OK, O rows affected (0.10 sec*)
N.B: I created a database (db_name) earlier and was creating a user credential with all privileges granted to all tables in the DB in place of using the default root user which I read somewhere is a best practice.

The specified user just doesn't exist on your MySQL (so, MySQL is trying to create it with GRANT as it did before version 8, but fails with the limitations, introduced in this version).
MySQL's pretty dumb at this point, so if you have 'root'#'localhost' and trying to grant privileges to 'root'#'%' it treats them as different users, rather than generalized notion for root user on any host, including localhost.
The error message is also misleading.
So, if you're getting the error message, check your existing users with something like this
SELECT CONCAT("'", user, "'#'", host, "'") FROM mysql.user;
and then create missing user (as Mike advised) or adjust your GRANT command to the actual exisiting user specificaion.

You will get this error
ERROR 1410 (42000): You are not allowed to create a user with GRANT
If you are trying to run a GRANT on a user that doesn't exist!
Therefore, first run this to make sure the user you use in your GRANT matches exactly to what you have:
select User, Host from user;
In particular pay attention whether the user you created is at localhost but the one you are trying to grant to is %

Copy this and use it at once:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL ON *.* TO 'username'#'localhost';
FLUSH PRIVILEGES;
Instead of using single lines of code such as:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
Then:
GRANT ALL ON *.* TO 'username'#'localhost';
Then:
FLUSH PRIVILEGES;

Many thanks #Nebulastic
If you want to only allow remote IP using following command
CREATE USER 'user_test'#'113.yy.xx.94' IDENTIFIED BY 'YOUR_PWD';
GRANT ALL ON *.* TO 'user_test'#'113.yy.xx.94';
FLUSH PRIVILEGES;

This worked for me:
mysql> FLUSH PRIVILEGES
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES

Check out your username and domain is the same as created before. Mysql select account by the two colums in user table.If it is different, mysql may think you want to create a new account by grant,which is not supported after 8.0 version.

My Specs:
mysql --version
mysql Ver 8.0.19 for Linux on x86_64 (MySQL Community Server - GPL)
What worked for me:
mysql> USE mysql;
mysql> UPDATE User SET Host='%' WHERE User='root' AND Host='localhost';

this commands work for me:
1-login to mysql and see all users
sudo mysql -u root
select user, host from mysql.user;
2-delete old user
drop user root#localhost;
3-create new user
CREATE USER 'root'#'localhost' IDENTIFIED BY 'mypassword'
4-add all privileges to it:
GRANT ALL ON *.* TO 'root'#'localhost'
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password
BY 'mypassword';
5-finally flush privileges
FLUSH PRIVILEGES;

in select statement, changing 'user'#'%' to 'user'#'localhost' solved my problem

In my case I wanted to do something similar, I followed some steps from here but the best way was as #nebulasic mentioned:
USE mysql;
CREATE USER 'user'#'localhost' IDENTIFIED BY 'P#ssW0rd';
GRANT ALL ON *.* TO 'user'#'localhost';
FLUSH PRIVILEGES;
After this I encountered an error while trying to query the database or connect with SQLTools from VSCode.
Client does not support authentication protocol requested by server; consider upgrading MySQL client
Running this query will fix the problem:
ALTER USER 'user'#'localhost' IDENTIFIED WITH mysql_native_password BY 'Your_newP#s$w0Rd';
I also want to mention that these steps are ok to work in a local environment, when doing something in production is recommended to allocate each user to each database with generated password accordingly and different other security measures if necessary.

Well, I just had the same problem. Even if route had '%' could not connect remotely. Now, having a look at my.ini file (config file in windows) the bind-address statement was missed.
So... I putted this bind-address = * after [mysqld] and restarted the service. Now it works!

1. grant privileges
mysql> GRANT ALL PRIVILEGES ON . TO 'root'#'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES
2. check user table:
mysql> use mysql
mysql> select host,user from user
3.Modify the configuration file
mysql default bind ip：127.0.0.1, if we want to remote visit services,just delete config
#Modify the configuration file
vi /usr/local/etc/my.cnf
#Comment out the ip-address option
[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1
4.finally restart the services
brew services restart mysql

Try this, i had the same issue and i tried few options, but the below worked.
GRANT ALL ON . TO 'root'#'%';
Reference used - https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu-20-04#step-6-%E2%80%94-testing-database-connection-from-php-optional

ubuntu 22.04.1
Mysql Ver 8.0.31-0
My root had no GRANT privileges so I could not grant new users any previligies.
Solution was to Drop current root user and create new one using 'mysql_native_password'.
Commands as follows
Login to mysql with as root
mysql> DROP USER 'root'#'localhost' IDENTIFIED BY 'PASSWORD' FROM mysql.user;
mysql> CREATE USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'locahost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;

This may work:
grant all on dbtest.* to 'dbuser'#'%' identified by 'mysql_password';

I had this same issue, which led me here. In particular, for local development, I wanted to be able to do mysql -u root -p without sudo. I don't want to create a new user. I want to use root from a local PHP web app.
The error message is misleading, as there was nothing wrong with the default 'root'#'%' user privileges.
Instead, as several people mentioned in the other answers, the solution was simply to set bind-address=0.0.0.0 instead of bind-address=127.0.0.1 in my /etc/mysql/mysql.conf.d/mysqld.cnf config. No changes were otherwise required.

I had the same problem on CentOS and this worked for me (version: 8.0.11):
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'#'%'

Stary mysql with sudo
sudo mysql

java desktop application - sharing one database to client computers [duplicate]

This should be dead simple, but I cannot get it to work for the life of me.
I'm just trying to connect remotely to my MySQL server.
Connecting as:
mysql -u root -h localhost -p
works fine, but trying:
mysql -u root -h 'any ip address here' -p
fails with the error:
ERROR 1130 (00000): Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server
In the mysql.user table, there is exactly the same entry for user 'root' with host 'localhost' as another with host '%'.
I'm at my wits' end and have no idea how to proceed.
Any ideas are welcome.

Possibly a security precaution. You could try adding a new administrator account:
mysql> CREATE USER 'monty'#'localhost' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'#'localhost'
-> WITH GRANT OPTION;
mysql> CREATE USER 'monty'#'%' IDENTIFIED BY 'some_pass';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'monty'#'%'
-> WITH GRANT OPTION;
Although as Pascal and others have noted it's not a great idea to have a user with this kind of access open to any IP. If you need an administrative user, use root, and leave it on localhost. For any other action specify exactly the privileges you need and limit the accessibility of the user as Pascal has suggest below.
Edit:
From the MySQL FAQ:
If you cannot figure out why you get
Access denied, remove from the user
table all entries that have Host
values containing wildcards (entries
that contain '%' or '_' characters). A
very common error is to insert a new
entry with Host='%' and
User='some_user', thinking that this
allows you to specify localhost to
connect from the same machine. The
reason that this does not work is that
the default privileges include an
entry with Host='localhost' and
User=''. Because that entry has a Host
value 'localhost' that is more
specific than '%', it is used in
preference to the new entry when
connecting from localhost! The correct
procedure is to insert a second entry
with Host='localhost' and
User='some_user', or to delete the
entry with Host='localhost' and
User=''. After deleting the entry,
remember to issue a FLUSH PRIVILEGES
statement to reload the grant tables.
See also Section 5.4.4, “Access
Control, Stage 1: Connection
Verification”.

One has to create a new MySQL User and assign privileges as below in Query prompt via phpMyAdmin or command prompt:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'localhost' WITH GRANT OPTION;
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Once done with all four queries, it should connect with username / password

My error message was similar and said 'Host XXX is not allowed to connect to this MySQL server' even though I was using root. Here's how to make sure that root has the correct permissions.
My setup:
Ubuntu 14.04 LTS
MySQL v5.5.37
Solution
Open up the file under etc/mysql/my.cnf
Check for:
port (by default this is port = 3306)
bind-address (by default this is bind-address = 127.0.0.1; if you want to open to all then just comment out this line. For my example, I'll say the actual server is on 10.1.1.7)
Now access the MySQL Database on your actual server (say your remote address is 123.123.123.123 at port 3306 as user root and I want to change permissions on database 'dataentry'. Remember to change the IP Address, Port, and database name to your settings)
mysql -u root -p
Enter password: <enter password>
mysql>GRANT ALL ON *.* to root#'123.123.123.123' IDENTIFIED BY 'put-your-password';
mysql>FLUSH PRIVILEGES;
mysql>exit
sudo service mysqld restart
You should now be able to remote connect to your database. For example, I'm using MySQL Workbench and putting in 'Hostname:10.1.1.7', 'Port:3306', 'Username:root'

Just perform the following steps:
Connect to MySQL (via localhost)
mysql -uroot -p
If the MySQL server is running in Kubernetes (K8s) and being accessed via a NodePort
kubectl exec -it [pod-name] -- /bin/bash
mysql -uroot -p
Create user
CREATE USER 'user'#'%' IDENTIFIED BY 'password';
Grant permissions
GRANT ALL PRIVILEGES ON *.* TO 'user'#'%' WITH GRANT OPTION;
Flush privileges
FLUSH PRIVILEGES;

You need to grant access to the user from any hostname.
This is how you add new privilege from phpmyadmin
Goto Privileges > Add a new User
Select Any Host for the desired username

Simple way:
Grant All Privileges ON *.* to 'USER_NAME'#'%' Identified By 'YOUR_PASSWORD';
then
FLUSH PRIVILEGES;
done!

The message *Host ''xxx.xx.xxx.xxx'' is not allowed to connect to this MySQL server is a reply from the MySQL server to the MySQL client. Notice how its returning the IP address and not the hostname.
If you're trying to connect with mysql -h<hostname> -u<somebody> -p and it returns this message with the IP address, then the MySQL server isn't able to do a reverse lookup on the client. This is critical because thats how it maps the MySQL client to the grants.
Make sure you can do an nslookup <mysqlclient> FROM the MySQL server. If that doesn't work, then there's no entry in the DNS server. Alternatively, you can put an entry in the MySQL server's HOSTS file (<ipaddress> <fullyqualifiedhostname> <hostname> <- The order here might matter).
An entry in my server's host file allowing a reverse lookup of the MySQL client solved this very problem.

This working for any future remote mysql connection !
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Navigate to the line that begins with the bind-address directive. It should look like this:
bind-address = 0.0.0.0
Login to your mysql as root terminal
mysql -u root -p
-- root password
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'localhost' WITH GRANT OPTION;
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
EXIT;
finally Grant that machine exclusive permission to connect to the database remotely with the following command.
sudo ufw allow from remote_IP_address to any port 3306

If you modify the grant tables manually (using INSERT, UPDATE, etc.), you should execute
a FLUSH PRIVILEGES statement to tell the server to reload the grant tables.
PS: I wouldn't recommend to allow any host to connect for any user (especially not the root use). If you are using mysql for a client/server application, prefer a subnet address. If you are using mysql with a web server or application server, use specific IPs.

Just use the interface provided by MySql's GUI Tool (SQLyog):
Click on User manager:
Now, if you want to grant access FOR ANY OTHER REMOTE PC, just make sure that, just like in the underneath picture, the Host field value is % (which is the wildcard)

Most of the answers here show you creating users with two host values: one for localhost, and one for %.
Please note that except for a built-in localhost user like root, you don't need to do this. If you simply want to make a new user that can log in from anywhere, you can use
CREATE USER 'myuser'#'%' IDENTIFIED BY 'mypassword';
GRANT <whatever privileges are appropriate> ON <relevant tables> TO myuser;
and it will work just fine. (As others have mentioned, it's a terrible idea to grant administrative privileges to a user from any domain.)

If you are using MySQL WorkBench, you can achieve this easily:
From the menu, select Server -> Users And Privileges
On the lower left, click on "Add account"
Fill the form with username, host matching (% means every host) and the password
Click on "Apply" on the lower right
After this you are good to go. Then, if you want to refine your configuration, you can use the "Administrative Roles" tab to set the command that can be used by the user (SELECT, ALTER etc etc) and the "Schema privileges" tab to restrict the user interaction to specific schemas.

Well, nothing of the above answer worked for me. After a lot of research, I found a solution. Though I may be late this may help others in future.
Login to your SQL server from a terminal
mysql -u root -p
-- root password
GRANT ALL ON *.* to root#'XX.XXX.XXX.XX' IDENTIFIED BY 'password';
This should solve the permission issue.
Happy coding!!

simple way is to login to phpmyadmin with root account , there goto mysql database and select user table , there edit root account and in host field add % wild card . and then through ssh flush privileges
FLUSH PRIVILEGES;

If this is a recent mysql install, then before changing anything else, try simply to execute this command and then try again:
flush privileges;
This alone fixes the issue for me on Ubuntu 16.04, mysql 5.7.20. YMMV.

Just find a better way to do that from your hosting control panel (I'm using DirectAdmin here)
simply go to the target server DB in your control panel, in my case:
MySQL management -> select your DB -> you will find: "Access Hosts", simply add your remote host here and its working now!
I guess there is a similar option on other C.panels like plesk, etc..
I'm hope it was helpful to you too.

If you happen to be running on Windows; A simple solution is to run the MySQL server instance configuration wizard. It is in your MYSQL group in the start menu. On the second from last screen click the box that says "allow root access from remote machines".

CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
this error because no password to the root , and this Maybe occurred with you when you trying to connect from outside .

If you have WAMP Server + Windows 10 and you are using it for development than Right Click on Wamp Icon => Wamp Settings => Check Allow Virtual Hosts other than 127*

I was also facing same issue, It resolved in 2 min for me i just white list ip through cpanel
Suppose you are trying to connect database of server B from server A.
Go to Server B Cpanel->Remote MySQL-> enter Server A IP Address and That's it.

Well what you can do is just open mysql.cfg file and you have to change Bind-address to this
bind-address = 127.0.0.1
and then Restart mysql and you will able to connect that server to this.
Look this you can have idea form that.
this is real sol

This answer might help someone...
All these answers didnt help, then I realised I forgot to check one crucial thing.. The port :)
I have mysql running in a docker container running on a different port. I was pointing to my host machine on port 3306, which I have a mysql server running on. My container exposes the server on port 33060. So all this time, i was looking at the wrong server! doh!

This working for DirectAdmin;
Go to your DirectAdmin.
Go to your MySQL Management.
Select your database.
Under your Accesse Host tab, there is a field.
You should fill this field by xxx.xx.xxx.xx.
Click on Add Host.
Finished. Now you can access to this DB by your your_database_username & your_database_password.
So Simple!

CPANEL solution
Go to Cpanel, look for Remote MySQL.
Add the the IP in the input field:
Host (% wildcard is allowed)
Comment to remember what IP that is.
That was it for me.

1. From a terminal, connect you to your MySQL running container
docker exec -it your_container_name_or_id bash
2. In your container, connect you to the MySQL database
mysql -u your_user -p
enter your password to connect to database.
3. execute this SQL script to list all existing database users:
SELECT host, user FROM mysql.user;
The result will be some thing like below:
host
user
127.0.0.1
root
::1
root
localhost
mysql.sys
localhost
root
you should add a new row:
host
user
%
root
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;

Problem: root#localhost is unable to connect to a fresh installation of mysql-community-server on openSUSE 42.2-1.150.x86_64.
Mysql refuses connections - period.
Solution:
$ ls -l /var/lib/mysql/mysql/user.*
-rw-rw---- 1 mysql mysql 0 Apr 29 19:44 /var/lib/mysql/mysql/user.MYD
-rw-rw---- 1 mysql mysql 1024 Apr 29 19:44 /var/lib/mysql/mysql/user.MYI
-rw-rw---- 1 mysql mysql 10684 Apr 29 19:44 /var/lib/mysql/mysql/user.frm
File user.MYD has 0 size (really ?!).
I copied all 3 files from another working system.
$ /usr/sbin/rcmysql stop
$ cd /var/lib/mysql/mysql/
$ scp root#othersytem:/var/lib/mysql/mysql/user.* ./
$ /usr/sbin/rcmysql start
$ cd -
$ mysql -u root -p
I was able to log in. Then, it was just a matter of re-applying all schema privileges.
Also, if you disabled IPv6, re-enable it temporary so that root#::1 account can also work.

if you are trying to execute mysql query withouth defining connectionstring, you will get this error.
Probably you forgat to define connection string before execution. have you check this out?
(sorry for bad english)

All of the answers here didn't work in my case so I guest this may help other users in the future. This can also be a problem in our code, not just in MySQL alone.
If you are using VB.NET
Instead of this code:
Dim server As String = My.Settings.DB_Server
Dim username As String = My.Settings.DB_Username
Dim password As String = My.Settings.DB_Password
Dim database As String = My.Settings.DB_Database
MysqlConn.ConnectionString = "server=" & server & ";" _

You need to move MysqlConn = New MySqlConnection() on the first line. So it would be like this
MysqlConn = New MySqlConnection()
Dim server As String = My.Settings.DB_Server
Dim username As String = My.Settings.DB_Username
Dim password As String = My.Settings.DB_Password
Dim database As String = My.Settings.DB_Database
MysqlConn.ConnectionString = "server=" & server & ";" _
& "user id=" & username & ";" _

How to access MySQL Local Server, Error Class File Editor when use dynamic ip to change localhost [duplicate]

This should be dead simple, but I cannot get it to work for the life of me.
I'm just trying to connect remotely to my MySQL server.
Connecting as:
mysql -u root -h localhost -p
works fine, but trying:
mysql -u root -h 'any ip address here' -p
fails with the error:
ERROR 1130 (00000): Host 'xxx.xx.xxx.xxx' is not allowed to connect to this MySQL server
In the mysql.user table, there is exactly the same entry for user 'root' with host 'localhost' as another with host '%'.
I'm at my wits' end and have no idea how to proceed.
Any ideas are welcome.

One has to create a new MySQL User and assign privileges as below in Query prompt via phpMyAdmin or command prompt:
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'localhost' WITH GRANT OPTION;
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Once done with all four queries, it should connect with username / password

My error message was similar and said 'Host XXX is not allowed to connect to this MySQL server' even though I was using root. Here's how to make sure that root has the correct permissions.
My setup:
Ubuntu 14.04 LTS
MySQL v5.5.37
Solution
Open up the file under etc/mysql/my.cnf
Check for:
port (by default this is port = 3306)
bind-address (by default this is bind-address = 127.0.0.1; if you want to open to all then just comment out this line. For my example, I'll say the actual server is on 10.1.1.7)
Now access the MySQL Database on your actual server (say your remote address is 123.123.123.123 at port 3306 as user root and I want to change permissions on database 'dataentry'. Remember to change the IP Address, Port, and database name to your settings)
mysql -u root -p
Enter password: <enter password>
mysql>GRANT ALL ON *.* to root#'123.123.123.123' IDENTIFIED BY 'put-your-password';
mysql>FLUSH PRIVILEGES;
mysql>exit
sudo service mysqld restart
You should now be able to remote connect to your database. For example, I'm using MySQL Workbench and putting in 'Hostname:10.1.1.7', 'Port:3306', 'Username:root'

Just perform the following steps:
Connect to MySQL (via localhost)
mysql -uroot -p
If the MySQL server is running in Kubernetes (K8s) and being accessed via a NodePort
kubectl exec -it [pod-name] -- /bin/bash
mysql -uroot -p
Create user
CREATE USER 'user'#'%' IDENTIFIED BY 'password';
Grant permissions
GRANT ALL PRIVILEGES ON *.* TO 'user'#'%' WITH GRANT OPTION;
Flush privileges
FLUSH PRIVILEGES;

You need to grant access to the user from any hostname.
This is how you add new privilege from phpmyadmin
Goto Privileges > Add a new User
Select Any Host for the desired username

Simple way:
Grant All Privileges ON *.* to 'USER_NAME'#'%' Identified By 'YOUR_PASSWORD';
then
FLUSH PRIVILEGES;
done!

The message *Host ''xxx.xx.xxx.xxx'' is not allowed to connect to this MySQL server is a reply from the MySQL server to the MySQL client. Notice how its returning the IP address and not the hostname.
If you're trying to connect with mysql -h<hostname> -u<somebody> -p and it returns this message with the IP address, then the MySQL server isn't able to do a reverse lookup on the client. This is critical because thats how it maps the MySQL client to the grants.
Make sure you can do an nslookup <mysqlclient> FROM the MySQL server. If that doesn't work, then there's no entry in the DNS server. Alternatively, you can put an entry in the MySQL server's HOSTS file (<ipaddress> <fullyqualifiedhostname> <hostname> <- The order here might matter).
An entry in my server's host file allowing a reverse lookup of the MySQL client solved this very problem.

This working for any future remote mysql connection !
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Navigate to the line that begins with the bind-address directive. It should look like this:
bind-address = 0.0.0.0
Login to your mysql as root terminal
mysql -u root -p
-- root password
CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'localhost' WITH GRANT OPTION;
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
EXIT;
finally Grant that machine exclusive permission to connect to the database remotely with the following command.
sudo ufw allow from remote_IP_address to any port 3306

If you modify the grant tables manually (using INSERT, UPDATE, etc.), you should execute
a FLUSH PRIVILEGES statement to tell the server to reload the grant tables.
PS: I wouldn't recommend to allow any host to connect for any user (especially not the root use). If you are using mysql for a client/server application, prefer a subnet address. If you are using mysql with a web server or application server, use specific IPs.

Just use the interface provided by MySql's GUI Tool (SQLyog):
Click on User manager:
Now, if you want to grant access FOR ANY OTHER REMOTE PC, just make sure that, just like in the underneath picture, the Host field value is % (which is the wildcard)

Most of the answers here show you creating users with two host values: one for localhost, and one for %.
Please note that except for a built-in localhost user like root, you don't need to do this. If you simply want to make a new user that can log in from anywhere, you can use
CREATE USER 'myuser'#'%' IDENTIFIED BY 'mypassword';
GRANT <whatever privileges are appropriate> ON <relevant tables> TO myuser;
and it will work just fine. (As others have mentioned, it's a terrible idea to grant administrative privileges to a user from any domain.)

If you are using MySQL WorkBench, you can achieve this easily:
From the menu, select Server -> Users And Privileges
On the lower left, click on "Add account"
Fill the form with username, host matching (% means every host) and the password
Click on "Apply" on the lower right
After this you are good to go. Then, if you want to refine your configuration, you can use the "Administrative Roles" tab to set the command that can be used by the user (SELECT, ALTER etc etc) and the "Schema privileges" tab to restrict the user interaction to specific schemas.

Well, nothing of the above answer worked for me. After a lot of research, I found a solution. Though I may be late this may help others in future.
Login to your SQL server from a terminal
mysql -u root -p
-- root password
GRANT ALL ON *.* to root#'XX.XXX.XXX.XX' IDENTIFIED BY 'password';
This should solve the permission issue.
Happy coding!!

simple way is to login to phpmyadmin with root account , there goto mysql database and select user table , there edit root account and in host field add % wild card . and then through ssh flush privileges
FLUSH PRIVILEGES;

If this is a recent mysql install, then before changing anything else, try simply to execute this command and then try again:
flush privileges;
This alone fixes the issue for me on Ubuntu 16.04, mysql 5.7.20. YMMV.

Just find a better way to do that from your hosting control panel (I'm using DirectAdmin here)
simply go to the target server DB in your control panel, in my case:
MySQL management -> select your DB -> you will find: "Access Hosts", simply add your remote host here and its working now!
I guess there is a similar option on other C.panels like plesk, etc..
I'm hope it was helpful to you too.

If you happen to be running on Windows; A simple solution is to run the MySQL server instance configuration wizard. It is in your MYSQL group in the start menu. On the second from last screen click the box that says "allow root access from remote machines".

CREATE USER 'username'#'localhost' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
this error because no password to the root , and this Maybe occurred with you when you trying to connect from outside .

If you have WAMP Server + Windows 10 and you are using it for development than Right Click on Wamp Icon => Wamp Settings => Check Allow Virtual Hosts other than 127*

I was also facing same issue, It resolved in 2 min for me i just white list ip through cpanel
Suppose you are trying to connect database of server B from server A.
Go to Server B Cpanel->Remote MySQL-> enter Server A IP Address and That's it.

Well what you can do is just open mysql.cfg file and you have to change Bind-address to this
bind-address = 127.0.0.1
and then Restart mysql and you will able to connect that server to this.
Look this you can have idea form that.
this is real sol

This answer might help someone...
All these answers didnt help, then I realised I forgot to check one crucial thing.. The port :)
I have mysql running in a docker container running on a different port. I was pointing to my host machine on port 3306, which I have a mysql server running on. My container exposes the server on port 33060. So all this time, i was looking at the wrong server! doh!

This working for DirectAdmin;
Go to your DirectAdmin.
Go to your MySQL Management.
Select your database.
Under your Accesse Host tab, there is a field.
You should fill this field by xxx.xx.xxx.xx.
Click on Add Host.
Finished. Now you can access to this DB by your your_database_username & your_database_password.
So Simple!

CPANEL solution
Go to Cpanel, look for Remote MySQL.
Add the the IP in the input field:
Host (% wildcard is allowed)
Comment to remember what IP that is.
That was it for me.

1. From a terminal, connect you to your MySQL running container
docker exec -it your_container_name_or_id bash
2. In your container, connect you to the MySQL database
mysql -u your_user -p
enter your password to connect to database.
3. execute this SQL script to list all existing database users:
SELECT host, user FROM mysql.user;
The result will be some thing like below:
host
user
127.0.0.1
root
::1
root
localhost
mysql.sys
localhost
root
you should add a new row:
host
user
%
root
CREATE USER 'username'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'username'#'%' WITH GRANT OPTION;

Some tips:
list privileges using show grants;
create a VPN and just add the ip of the tunnel

Problem: root#localhost is unable to connect to a fresh installation of mysql-community-server on openSUSE 42.2-1.150.x86_64.
Mysql refuses connections - period.
Solution:
$ ls -l /var/lib/mysql/mysql/user.*
-rw-rw---- 1 mysql mysql 0 Apr 29 19:44 /var/lib/mysql/mysql/user.MYD
-rw-rw---- 1 mysql mysql 1024 Apr 29 19:44 /var/lib/mysql/mysql/user.MYI
-rw-rw---- 1 mysql mysql 10684 Apr 29 19:44 /var/lib/mysql/mysql/user.frm
File user.MYD has 0 size (really ?!).
I copied all 3 files from another working system.
$ /usr/sbin/rcmysql stop
$ cd /var/lib/mysql/mysql/
$ scp root#othersytem:/var/lib/mysql/mysql/user.* ./
$ /usr/sbin/rcmysql start
$ cd -
$ mysql -u root -p
I was able to log in. Then, it was just a matter of re-applying all schema privileges.
Also, if you disabled IPv6, re-enable it temporary so that root#::1 account can also work.

if you are trying to execute mysql query withouth defining connectionstring, you will get this error.
Probably you forgat to define connection string before execution. have you check this out?
(sorry for bad english)

All of the answers here didn't work in my case so I guest this may help other users in the future. This can also be a problem in our code, not just in MySQL alone.
If you are using VB.NET
Instead of this code:
Dim server As String = My.Settings.DB_Server
Dim username As String = My.Settings.DB_Username
Dim password As String = My.Settings.DB_Password
Dim database As String = My.Settings.DB_Database
MysqlConn.ConnectionString = "server=" & server & ";" _
& "user id=" & username & ";" _
& "password=" & password & ";" _
& "database=" & database
MysqlConn = New MySqlConnection()
You need to move MysqlConn = New MySqlConnection() on the first line. So it would be like this
MysqlConn = New MySqlConnection()
Dim server As String = My.Settings.DB_Server
Dim username As String = My.Settings.DB_Username
Dim password As String = My.Settings.DB_Password
Dim database As String = My.Settings.DB_Database
MysqlConn.ConnectionString = "server=" & server & ";" _
& "user id=" & username & ";" _
& "password=" & password & ";" _
& "database=" & database

Access denied for user 'test_user'#'test_host' (using password: YES)

I have a mysql user called test_user
GRANT all privileges on *.* to 'test_user'#'%' identified by 'test_passwd'
I can use this user remotely from my JAVA code. When i run the code in the server, i got
Access denied for user 'test_user'#'test_host' (using password: YES)
I already ran FLUSH PRIVILEGES; after grant all privileges for test_user and restarted the mysql service.
I tried to login mysql in the server using console
mysql -utest_user -ptest_passwd
ERROR 1045 (28000): Access denied for user 'test_user'#'localhost' (using password: YES)
It seems i can only using test_user remotely but not from the server itself. Any suggestions to fix this?
-------New test----------
I tried to do not provide password in the server, it is working
mysql -utest_user
I need to use password for both remotely and locally. Any suggestions?

I have run into a similar problem before.
Having % should allow a user to connect from anywhere including localhost assuming you granted privileges and flushed privileges. However, If you did not make a secure install of mysql you most likely have a ghost localhost left on your machine. So not only would you be able to just run mysql with no user, or password provided from localhost command line but the ghost localhost for some reason conflicts with any other users (besides root) that have been created from logging in on the localhost.
If you do select user, password, host from mysql.user; You will likely see a user with no name, no password and a host localhost.
Delete that user using drop user ''#'localhost;
flush privileges again.
Try to connect using your other user now on localhost and it should work.

It should be:
CREATE USER 'monty'#'%' IDENTIFIED BY 'some_pass';
and then
GRANT ALL PRIVILEGES ON *.* TO 'monty'#'localhost'
-> WITH GRANT OPTION;
If it doesn't work, try logging in with root and see:
SHOW GRANTS FOR 'admin'#'localhost';
Replace your values everywhere

MYSQL Connection: Access Denied

These are my codes for the database connection:
Class.forName("com.mysql.jdbc.Driver");
con =DriverManager.getConnection("jdbc:mysql://10.44.222.111/try?"
+ "user=jenny&password=perez");
After running the program, it display this error:
com.mysql.jdbc.exception.jdbc4.MySQLSyntaxErrorException:
Access denied for user 'jenny' # '%' to database 'try'
I am using MySQL Workbench.

Go to MySQL Workbench, then User Privileges, click your username, then check all Administrative Roles then click apply. This will allow connection for user 'jenny'.

As the error says, user 'jenny' does not have access to connect to database from any host(%). On mysql prompt, run the following command to provide privileges to user 'jenny' to connect from any host.
GRANT ALL PRIVILEGES ON try.* TO 'jenny'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
You may use specific PRIVILEGES instead of ALL as per your requirement.

This would indicate that your user does not have permission to access that database from any client host ('%').
MySQL uses a four part mechanism for allowing access:
username
password
database
client host
You need to make sure that the user is authorised in MySql to access the 'try' database and is allowed to connect from any client host ('%') and has the correct username and password.
Also, you should ensure you are connecting to port 3306 (unless MySQL is running on a non-standard port).
