Hi
I install moodle 3.2.1 on my centos.
All are ok.
But my moodle usually database down.
ExecStart=/usr/sbin/mysqld $MYSQLD_OPTS $_WSREP_NEW_CLUSTER $_WSREP_START_POSITION
/var/lib/mysql/mysql.sock' (111 "Connection refused")
At that time, I restart my centos. It is ok now.
But after sometime, sql down again.
I run the following command to fix.
#chown -R mysql. /var/lib/mysql/
#mysql_install_db --user=mysql --basedir=/usr --datadir=/var/lib/mysql
But don't work.
Thanks Ken Task.
I don't find mysql_log in /var/log/ and mysql.err log in /var/lib/mysql.
So I reinstall centos 7 in the following link.

After that my site has no error till now. Thanks.
So MariaDB is enabled and started fine on boot, but at some point it appears to have stopped?
If you run systemctl status mariadb when you get this error, what is the result? If it is inactive, it may state since when, so you can correlate that with other logs.
If you check mysql.err log in /var/lib/mysql as per Ken's suggestion you may find an error there. If empty, you may need to define this in my.cnf log-error = /path/to/error/log
It may also be worth checking the error logs for Apache (or whatever you are using) to see if anything triggered MariaDB to stop.
