Mysql: host not allowed to connect

The issue I was encountering was that MySQL 5.1.3 on Ubuntu 9.10 was not allowing external connections, i.e. connections from a host different from the host the server is running on.

Okay, my dirty fix was(all the commands were run from a terminal):

First edit /etc/mysql/my.cnf:

user@ubuntu:~$ sudo nano /etc/mysql/my.cnf

and find a line like

 bind-address            = 127.0.0.1

,then add another line below stating your public address:

bind-address            =192.168.0.4

In my case 192.168.0.4 was the IP for which I wanted to enable remote connections.

127.0.0.1 is (always) the IP for localhost, I didn't touch that line so local applications(such as PHP) can connect as well.

After saving, login into mysql

mysql -u root -p

'root' being the username. You will be prompted for your password.

Now, we need to take a look at the MySQL users system table:

mysql> select host, user from mysql.user;
+-----------+------------------+
| host      | user             |
+-----------+------------------+
| 127.0.0.1 | root             |
| localhost | debian-sys-maint |
| localhost | root             |
| ubuntu    | root             |
+-----------+------------------+
4 rows in set (0.00 sec)

 Probably the best way to fix privileges is to add another user and follow the instructions from

MySQL :: MySQL 5.5 Reference Manual :: 2.11.3 Securing the Initial MySQL Accounts

What i did instead was:

mysql> update mysql.user set host='%' where host='127.0.0.1';

 and when checking the users table again i get:

 mysql> select host, user from mysql.user;
+-----------+------------------+
| host      | user             |
+-----------+------------------+
| %         | root             |
| localhost | debian-sys-maint |
| localhost | root             |
| ubuntu    | root             |
+-----------+------------------+
4 rows in set (0.00 sec)

Things are fine, % stands for 'any host'. Now we logout from mysql with Ctrl+D and restart the server:

user@ubuntu:~$ sudo service mysql restart

All done, good luck!
