systemctl can't start mysql on centos 7

Question

I'm trying to start mysql on centos 7. (centos is running in a vagrant box, using vmware-workstation as the provider) I have a chef script which fails trying to start mysql using the chef cookbook.

At this point I'm just trying to ssh into the box and get mysql started manually and here is the output i get:

(cms-env)[GISO@localhost ~]$ sudo systemctl start mysql-cms
Job for mysql-cms.service failed. See 'systemctl status mysql-cms.service' and '
journalctl -xn' for details.


[GISO@localhost ~]$ sudo systemctl -l status mysql-cms.service

I've been digging around trying to solve this for hours. Have downloaded all recommended development libraries, etc...Can't figure out what is making this fail. Any help is greatly appreciated! thanks

edit: I was able to dig up some more logs here via sudo journalctl -l | grep mysql sudo journalctl -l | grep mysql (I apologize for the formatting)

Answer 1

CentOS is transitioning mysql to mariadb. Under /usr/lib/systemd/system you should find the file mariadb.service . Simply run

sudo systemctl start mariadb.service

Then mysql command operates!

Answer 2

Failed to setup SSL Jul 06 00:43:34 localhost.localdomain mysqld[2184]: 2015-07-06T04:43:34.787331Z 0 [Warning] SSL error: SSL context is not usable without certificate and private key

That's the core of the problem.

Looks like this is a known issue: https://bugs.mysql.com/bug.php?id=80335

"For more information, see Section 4.4.5, “mysql_ssl_rsa_setup — Create SSL/RSA "Files”.

You need to run mysql_ssl_rsa_setup.
