If MySQL won't start because of permissions problems (try running

   sudo -u mysql mysqld

or check /var/log/messages and /var/log/mysql/error.log, then this is the 
same problem that I am having.  (Especially if you have changed the location 
of some files from the defaults.)

Check that data and log file directories have the correct rw
permissions.

Then check /etc/apparmor.d/usr.sbin.mysqld permissions.

[Bug 582970] Re: mysql-server won't start after update

2010-05-19 Thread Robert
I've found the cause of the problem. It was due to mysql not having
permissions to the appropriate directories in AppArmor.  Changing them
fixed it.

Question: why did MySQL run before the update without the permissions?!?
(Another bug report, I think.)

** Changed in: mysql-dfsg-5.1 (Ubuntu)
   Status: New => Fix Released

Ok. It's not being given access, even though the permissions on the
files are fine. So what's blocking it?
