MySQL root access from all hosts

There’s two steps in that process:

a) Grant privileges. As root user execute:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password';

b) bind to all addresses:

The easiest way is to comment out the line in your my.cnf file:

#bind-address = 127.0.0.1 

and restart mysql

service mysql restart

By default it binds only to localhost, but if you comment the line it binds to all interfaces it finds. Commenting out the line is equivalent to bind-address=*.

To check where mysql service has binded execute as root:

netstat -tupan | grep mysql
