[CentOS] mariadb fails to start under C7

[Tim Dunphy]

Actually, the systemctl command is:

   systemctl start mysql.service

from the "systemctl show" output it looks like this actually calls
the /etc/rc.d/init.d/mysql file for start/stop/reload, which seems
backwards.

It appears that mariadb is trying to be a total drop-in replacement
to mysql, so all the paths/files, etc., e.g., in the ps output, are
"mysql" not "mariadb" -- so it's tricky to have them both installed.

By the way, you can use things like:

   systemctl list-units

(and likely more efficient approaches) to find the systemctl command

> naming.





By gum! That seems to have done it!! Thank you very much for those tips!

[root at nfsdb1 ~]# systemctl list-units | grep -i mysql
mysql.service
loaded active running   LSB: start and stop MySQL

[root at nfsdb1 ~]#  systemctl start mysql.service

[root at nfsdb1 ~]# lsof -i :3306
COMMAND PID  USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
mysqld  839 mysql   16u  IPv6  15270      0t0  TCP *:mysql (LISTEN)

And then I just ran mysql_secure_install and now I can log into the DB!

Thanks so much for the help! The CentOS list rocks!!
