[CentOS] restarting mysql databases

[John Plemons]

Did you do the /usr/bin/mysql_secure_install

Sounds like that is the issue, run mysql_secure_install

It will setup MySQL securely with a simple set of questions and 
answers..  Yes is the right answer for most of the questions.

Here is a link to LAMP Stack for Centos, the MySQL section is just below 
the Apache install section..

Also good for CentOS 7
