AppArmor support

[Noel McLoughlin]

On Ubuntu 18.04 stack.sh failed because MySQL cannot write to /var/lib/mysql/

This is caused by Apparmor. The following workaround was required-

$ echo '/var/lib/mysql/ r,' > /etc/apparmor.d/local/usr.sbin.mysqld
$ echo '/var/lib/mysql/** rwk,' > /etc/apparmor.d/local/usr.sbin.mysqld

Correction.

$ echo '/var/lib/mysql/ r,' > /etc/apparmor.d/local/usr.sbin.mysqld
$ echo '/var/lib/mysql/** rwk,' >> /etc/apparmor.d/local/usr.sbin.mysqld

Please show details of how you are seeing issues, how did you install Ubuntu, which version of devstack are you using? Please attach your local.conf and the complete log from the stack.sh run on a fresh machine.

For my setup, I cannot reproduce this and I find that /etc/apparmor.d/usr.sbin.mysqld which belongs to mysql-server-5.7==5.7.24-0ubuntu0.18.04.1 already has the lines you want to add.

I think this was related to https://bugs.launchpad.net/devstack/+bug/1735097 where mariadb is installed before devstack runs. I made sure mariadb is not installed before devstack. I'm happy to close the issue.
