MySQL/Wordpress issue

jmoore

Wow, tough problem. Let me think about it some more. Have you taken any backups recently in case you have to reinstall?

WLS-ITGuy

I have daily snapshots and full backups.

jmoore

Have you changed any permissions or config files recently?

I had some issues with wordpress updating and had done some permission changes to wordpress files

Well it can be hard to diagnose things at times so in the interest of your time you might consider uninstalling mysql, reinstalling mysql, then importing your database back into mysql. Just consider it for now. Let others chime in for a bit in case someone else gets something to work for you.

Are you just running a single WordPress site here?

Yes. Single site.

Given that the site is now down... is there a good reason that you are running a WP site on your own instead of through a server (asks the guy who runs a service for that.)

It has been 2+ years since it has been set up this way. Wasn't broken, why fix it.

Someone had to set it up that way to start with

and...

Well wordpress and the database communicate with each other so that could possibly be it but I'm not sure. Usually when Wordpress doesn't update it is because permissions are too stringent and you therefore loosen them. I doubt loosening permissions would break mysql. Thats why I am doubtful if that is all you did.

Wrong. . . . .

You patch and update to ensure things remain functional.

Not what I was asked. It has been patched to the version I have. Just not upgraded to Debian 9.

Updating is not AS important as patching, but is important. Older systems become continuously harder and harder to maintain over time and eventually start having their own risks of things breaking - partially because other things change around them and they don't adapt to them. Partially just because the gap between them and current gets larger and larger and knowledge of supporting them or the ability to update gets harder.

Try shutting down Apache. THEN bring up MySQL. Let's see if MySQL dies when nothing is touching it.

scottalanmiller

If MySQL dies when Apache is offline, then we can rule out issues with Apache or WordPress as being the problem. I'm assuming this is a pure MySQL issue, but want to be sure.

What I meant by my statement was that it has been working. We didn't see a need to move it off a host to a wordpress specific site. I update it regularly but wasn't ready to upgrade to a new version of Debian at this time.

Well I think things are looking up. That was a good idea from Scott to shut down Apache and then work with mysql. I think you can go ahead and start Apache back up and let those run for a while to see what happens.

WLS-ITGuy

As soon as I start Apache2 MySQL stops working.

jmoore

@wls-itguy Well thats a bummer. What does your apache error log say when that happens?

scottalanmiller

Okay, there is a really good chance that we have a WordPress issue here. I think that rolling back to before the last update might be the logical place to start.

Any bets on a compromised plugin causing issues?

If you want to isolate to WP (thought I cannot see how it is anything else), I would shut down apache, mv your WP directory elsewhere and start apache back up.
