I have a CentOS server which runs few web sites. Suddenly all the web sites stopped functioning and when I check that I noticed that MySQL Service is down. I am new for this server related things. I executed following commands on WebMin since I have access for that.

> /etc/rc.d/init.d/mysqld start
bash: /etc/rc.d/init.d/mysqld: No such file or directory
> service mysqld start
mysqld: unrecognized service

It's really strange since it worked today morning even. Can someone help me in fixing this issue.

Thank you.

  • Maybe it isn't called mysqld. Depending on distro it can also be called simply 'mysql' or similar names. Check your /etc/init.d dir – Gnudiff Jan 5 '18 at 20:34

This looks like MySQL has been uninstalled

Check that:

rpm -qa | grep mysql

returns something like

    This is worked for me, before I have installed like yum install mysql only. That was the issue. Thank you @SSH This – Chaminda Bandara Oct 28 '18 at 7:59

I ran into a similar issue where MySQL service had gone down after some updates. The solution for me was a permissions issue with mysqld. The limited permissions did not allow mysqld to be executable. Try something like:

$ chmod 755 mysqld

I had just experienced a similar issue and solved it.

After a little soul searching was able to determine that I made a silly typo when installing the mysql package (typed mysql156-server instead of mysql56-server) and then missed the notice from Linux that no such package exists (I missed it because I was installing packages in bulk and Linux gave me a few hundred lines of success messages).

I suspect someone else may have done something similar, so just leaving this note here for posterity.
