My Apache and mysql server are installed on the same linux server.
In my mysql configuration file /etc/mysql/my.cnf, I have this line:

bind-address = 192.168.0.12

In my mysql database, I have a user db_user who can only connect from localhost

User     Server      Password   Global privileges  "Grant"
db_user  localhost   Yes        USAGE              No

What I don’t understand is: how can php connect to mysql tables with db_user and localhost domain if mysql is configured as binding only 192.168.0.12?

I checked the hosts file, localhost send to 127.0.0.1 and not 192.168.0.12.

And the other thing, this command on the server works :

mysql -udb_user -p”password” thedatabase

    If you specify localhost as the host to connect to, MySQL will use a socket, and not a TCP connection.
