ERROR: PleskFatalException: Unable to connect to database

[12lamat]

Hello, my server seems to have problems with mysql

ERROR: PleskFatalException: Unable to connect to database: mysql_connect(): No such file or directory (auth.php:142)

I performed a yum update and i think mysql had an update!

This is what i get when i go to a joomla website:
Error displaying the error page: Application Instantiation Error

or on another webpage it states not able to connect to database.

And i als o got this in plesk CP
