Question

Actualy my server updated PHP to 5.3.6 from 5.2.x. After this- all my mysql connections failed. I catch such PDO error
Connection failed: SQLSTATE[HY000] [2002] No such file or directory
Also checked in php.ini file value of the pdo_mysql.default_socket which is /tmp/mysql.sock

Host service told me to repair my mysql DB passwords. But it didn’t help.
Can somebody help me with this issue?

Answer 1

hehe, nice support 😉 This has absolutely nothing to do with the passwords. PDO_MySQL communicates under linux via sockets with the mysql-server. First of all find out, where is the socket now. (Sorry, but I dont know how :X)

If you have access to the php.ini, change

pdo_mysql.default_socket = /path/to/mysql.sock

If you dont have access to it, change the the instanciation of the pdo-object like described under PDO_MySQL Connection

$db = new PDO('mysql:unix_socket=/path/to/mysql.sock;dbname=testdb');

You probably must change/add some settings here.
