MySQL db refusing to start after Ubuntu 16.04.1 reboot
-
I thought that Ubuntu came with MariaDB, not MySQL. Where did you get MySQL?

/usr/sbin/mysqld
Just checked. There is no file named "/usr/sbin/mysqld"

Installed from "sudo apt-get install mysql-server"

Did you create a user outside of root on this system? If so check under that user account.

Oh okay, maybe they didn't switch. I run my databases on CentOS so might have missed that they hung back on MySQL.

The fact that you don't see the path means that either your running under the wrong account (don't have permission) or that something was removed.

@DustinB3403 I created a new user with select, update, insert delete privs on a new database within mysql but there nothing under any other users anywhere. I've been using this user for the past 2 days and it worked well.
I should mention that mysql is running on the standard port and nothing has been changed on the mysqld.cnf file.

Can you try this...
sudo apt-get install apparmor-profiles apparmor-profiles-extra apparmor-docs apparmor-utilsSee if that does anything?

The root account still existed in the mysql.user table, along with the debian maintenance account that is setup during install. I added a new underpriviledged user to the mysql.user table but not to the server. Thatis still running under the only account that exists.

This did install additional packages but mysql service still isn't starting however this time the output of journalctl -xe shows:
-- Subject: Unit mysql.service has failed -- Defined-By: systemd -- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel -- -- Unit mysql.service has failed. -- -- The result is failed.

Ok, I started looking into the error.log file to get more info about what was happening. I found that there was an error about not being able to load something but the log file was pretty large so I created a new log file to replace this one and went to restart mysql so I would have the one attempt's worth of records to review. To my surprise, after having provided a new error.log file, mysql started up no problem. Not sure wtf that was all about or why it failed with the current error.log contents.
I'm removing mysql and starting from scratch to see if I can replicate the issue.
-
That's a weird one!
-
@scottalanmiller Why the heck would a log file stop a service from loading?!
-
@DustinB3403 No idea. But it worked.

Now that you resolved that issue, why are you using 16.04.1?

Because testing everything before upgrading to 16.10 is more work than I have time for right now.

Upgrades get harder and harder as you get more versions behind. 17.04 is less than two months away. Just keep in mind that the easiest process is updating on a roughly six month cycle with Ubuntu. It's the least chance of things breaking.
