Just had the same issue and followed the steps provided by Lost In Tokyo. This did not work for me. I then followed the steps by Kees Cook. Working fine with it disabled.
I spent at least 3 hours trying to figure out what the cause of the issue was. My logs are identical, except I am moving the data to another drive mounted on the system. This is on Jaunty. In addition to apparmor disallowing mysql user to write to other directories, it also is preventing the memlock option from working which forces mysql to use additional system memory instead of the disk for buffers, etc, greatly increasing performance. mysql-server: 5.1.30really5.0.75-0ubuntu10.2 apparmor: 2.3+1289-0ubuntu14 -- Confusing mysqld startup failure with apparmor (Hardy) https://bugs.launchpad.net/bugs/201799 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to mysql-dfsg-5.0 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
