Beta Branch fix MariaDB MySQL server start up on reboot in CentOS 7 in 123.09beta01

fix MariaDB MySQL server start up on reboot in CentOS 7 in 123.09beta01

MariaDB MySQL server start up on reboot's chkconfig alias command linking mysql to mariadb service names seems to be broken by MariaDB YUM packages now. Previously command chkconfig mysql on would alias to mariadb service and create the appropriate systemd symlinks required for MariaDB MySQL server to start up after a server reboot. The chkconfig mysql on command is alias to systemctl enable mysql. But seems both chkconfig mysql on and systemctl enable mysql are broken and do not create the appropriate systemd symlinks

systemd alias to mysql links to chkconfig mysql on

Code (Text):

systemctl enable mysql
mysql.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig mysql on

chkconfig mysql on does nothing now though

while chkconfig mariadb on and systemctl enable mariadb work in creating symlinks properly

Code (Text):

chkconfig mariadb on
Note: Forwarding request to 'systemctl enable mariadb.service'.
Created symlink from /etc/systemd/system/mysql.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/mysqld.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

Code (Text):

systemctl enable mariadb
Created symlink from /etc/systemd/system/mysql.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/mysqld.service to /usr/lib/systemd/system/mariadb.service.
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

when symlinks are properly setup to allow MariaDB MySQL server to start up on server reboot, you should see symlinks

---

in /etc/systemd/system/

Code (Text):

ls -lah /etc/systemd/system/ | grep mariadb
drwxr-xr-x   2 root root   99 Oct  8 06:52 mariadb.service.d
lrwxrwxrwx   1 root root   39 Nov 27 10:29 mysqld.service -> /usr/lib/systemd/system/mariadb.service
lrwxrwxrwx   1 root root   39 Nov 27 10:29 mysql.service -> /usr/lib/systemd/system/mariadb.service

and in /etc/systemd/system/multi-user.target.wants/

Code (Text):

ls -lah /etc/systemd/system/multi-user.target.wants/ | grep mariadb
lrwxrwxrwx   1 root root   39 Nov 27 10:29 mariadb.service -> /usr/lib/systemd/system/mariadb.service

If symlinks don't exist on CentOS 7 install, just run

Code (Text):

systemctl enable mariadb

and check for symlinks again

Or update latest 123.09beta01 or higher code via cmupdate command, and run and exit centmin.sh once for automatic fix if symlink is missing centmin.sh will automatically fix it.

So cmupdate, then change to /usr/local/src/centminmod, run centmin.sh and then exit

Code (Text):

cmupdate
cmdir
./centmin.sh

example of cmupdate

Code (Text):
