test first with 127.0.0.1

MySQL sockets work fine with LSPHP 5.3.x and up. I've used LSWS for years and support 3rd party client whom run it and it's 2 cpu versions and such.

Read error logs.

Also if it said upgrade, make sure you have ALL MySQL packages installed

yum search all MySQL

install the dev packages the client the libraries whatever there is make sure you have it all. Then re-compile php with mysql, mysqli, socket option too. The php.ini one can be wonky webzian guy, as a web host since 15 years whom is developing an OS and Web Hosting panel in my spare time I think I know best. I get paid thousands by people for a few hours of my tuning/cluster setups. This is the end of my free help sadly the OP doesn't seem to know what doing.

Good luck soliving your issue, if 127.0.0.1 works then whats the issue, ditch the socket not every php application works good with mysql socket.
