First thing to check is to make sure you have plenty of hard drive space. This is one reason mysql will crash.
If you have plenty of space, we will look into something else.

check MariaDB service is running

command:

systemctl status mariadb

mySQL password same in /etc/sentora/panel/cnf/db.php and your root current?

I am using centos with 1 gb of ram and a 30 GB hard disk, CPU 2.4 GHz


What is caused due to a lot of ram memory usage?
Here's a Screenshot of the memory usage ram.

So mariaDB running could you check if the root password same in /etc/sentora/panel/cnf/db.php and your root current?

http://dev.mysql.com/doc/refman/5.6/en/mysql.html

mysql --user=root --password=your_password

your_password is the one you find in /etc/sentora/panel/cnf/db.php
