Did you tried 'sh /script/reset-mysql-root-password YOURNEWPASSWORD'?
After that seems everything is ok!  ;D
Thanks a lot!!

inform here 'chkconfig --list|grep -i mysql|grep -v grep' and 'systemctl list-unit-files|grep mysql'.

 chkconfig --list|grep -i mysql|grep -v grep

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

      If you want to list systemd services use 'systemctl list-unit-files'.
      To see services enabled on particular target use
      'systemctl list-dependencies [target]'.

mysql             0:off   1:off   2:on   3:on   4:on   5:on   6:off

systemctl list-unit-files|grep mysql
shows no output

Look like mysql running in your vps from 'pgrep' and 'ps aux' information.

Yes becouse I've started it with "sh /script/restart-mysql" command after server booted.

With fresh restart:
pgrep mysql -a - no output
ps aux|grep -i mysql|grep -v grep - no output

Try reboot and then check with 'pgrep' a couple of times.

It starts delayed!
But my webpages shows Error 500 - Internal Server Error!

Try add:
Code: [Select]
socket=/var/lib/mysql/mysql.sock
bind-address=127.0.0.1
under '[mysqld]'

I've added but is the same. Mysql starts delayed and that for (I think) web server have to be restart for avoiding error 500.
