I have a MySQL 5.5.41 server running on Ubuntu 14.04 that already contains several databases of data, and I would like to enable binary logging. I want the binary logs to be placed in their own directory, /var/log/mysqld, which did not exist prior. I created the directory, set its permissions to mysql:root 0755, and added a file to /etc/mysql/conf.d with the following contents:


Unfortunately, running service mysql restart then failed to bring MySQL back up, and the MySQL error logs contain the message:

/usr/sbin/mysqld: File '/var/log/mysqld/mysql-bin.index' not found (Errcode: 2)

What do I have to do to get this to work?

It turns out the problem was caused by apparmor. I had to add the following two lines to /etc/apparmor.d/usr.sbin.mysqld:

  /var/log/mysqld/ r,
  /var/log/mysqld/* rw,

and then run apparmor_parser -r /etc/apparmor.d/usr.sbin.mysqld before restarting MySQL.
