It should be an easy task to restart a mysql server. However, I recently ran into this:
[root@ip-172-31-44-221 ~]# service mysqld start Redirecting to /bin/systemctl start mysqld.service Failed to issue method call: Unit mysqld.service failed to load: No such file or directory. [root@ip-172-31-44-221 ~]#
There was nothing in /etc/init.d setup for mysql. After an hour of research I discovered this:
1006 systemctl start mariadb.service 1007 systemctl enable mariadb.service 1008 /usr/bin/mysql_secure_installation
Apparently after installation of maria db you need to use systemctl.
