Warning: mysqli_connect(): (HY000/2002)
« on: March 11, 2018, 12:47:14 PM »
I have not made any changes myself as a user on the VDS server. I was using PHP versions 5.2 and 5.6 due to the scripters I used.

everything was normal and suddenly I started to get this error. the server company can not help. I have to recover the latest updated database backup.  Thank you from now.

Trying to start mysql server, please wait!
Try to restart CentOS Web Panel with command: sh /scripts/restart_cwpsrv

**Check your MySQL root password in: /usr/local/cwpsrv/htdocs/resources/admin/include/db_conn.php and /root/.my.cnf

Just ask to see a competent sysadmin. Sometimes can help deleting /var/lib/mysql/ib_logfile0 and /var/lib/mysql/ib_logfile1, sometimes can't and must be investigated.
