ERROR 1130 (HY000): Host '' is not allowed to connect to this MySQL server

$mysql -u root --host=127.0.0.1 -p

mysql>use mysql

mysql>GRANT ALL ON *.* to root@'%' IDENTIFIED BY 'redhat@123';

mysql>FLUSH PRIVILEGES;

mysql> SELECT host FROM mysql.user WHERE User = 'root';

Your root account, and this statement applies to any account, may only have been added with localhost access (which is recommended).

You can check this with:

SELECT host FROM mysql.user WHERE User = 'root';

If you only see results with localhost and 127.0.0.1, you cannot connect from an external source. If you see other IP addresses, but not the one you're connecting from - that's also an indication.

You will need to add the IP address of each system that you want to grant access to, and then grant privileges:

CREATE USER 'root'@'ip_address' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'ip_address';

If you see %, well then, there's another problem altogether as that is "any remote source". If however you do want any/all systems to connect via root, use the % wildcard to grant access:

CREATE USER 'root'@'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%';

Finally, reload the permissions, and you should be able to have remote access:

FLUSH PRIVILEGES;

mysql> CREATE USER 'name'@'%' IDENTIFIED BY 'passWord'; Query OK, 0 rows affected (0.00 sec)

mysql> GRANT ALL PRIVILEGES ON . TO 'name'@'%'; Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)

mysql>

  1. Make sure you have your name and % the right way round
  2. Makes sure you have added your port 3306 to any firewall you may be running (although this will give a different error message)

hope this helps someone...


Following two steps worked perfectly fine for me:

  1. Comment out the bind address from the file /etc/mysql/my.cnf:

    #bind-address = 127.0.0.1

  2. Run following query in phpMyAdmin:

    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;
