Cannot find my sock

[frenchpl]

Hi
I am migrating my mysql database from windows xp to centos 6.
I have the database up and running on the linux.
However I cannot connect to it through firefox as I usually do on windows.
I am pretty sure that my PHP scripts are OK and this is a configuration issue.
Reading the error logs I find that it is trying to connect via /var/lib/mysql/mysql.sock and cannot find it

[Thu Jan 26 08:14:19 2017] [error] [client ::1] PHP Warning:  mysql_connect(): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) in /var/www/htdocs/HomeLogIn.php on line 87, referer: http://localhost/HomeLogIn.php

The correct location is of course /var/run/mysqld/mysql.sock

There is obviously a configuration file somewhere that is setting the wrong path info, however I cannot find it.

/etc/my.cnf is correct as is /etc/php.ini to the best of my knowledge
------------------------------------------------
my.cnf
[client]
port=3306
socket                         = /var/run/mysqld/mysql.sock
# SERVER SECTION
[mysqld]
# The TCP/IP Port the MySQL Server will listen on
port=3306
socket                         = /var/run/mysqld/mysql.sock
#Path to the database root
datadir="/var/lib/mysql/mysql"
--------------------------------

I checked the /etc/httpd content and that seemed OK too.

Obviously I am missing one somewhere but where, any thoughts please?
I tried restarting Mysql with no effect at all.
In fact shutting down the machine and restarting it makes no difference either.

The mysql_* functions are ancient and have been removed from the latest PHP branch.

 

Use PDO and specifiy the socket path either in the DSN string or in the PHP configuration.
