linux mysql errorcode 29

If mysqld is included in enforce mode

 when AppArmor blocks the writes/accesses. What you can do is edit


/etc/apparmor.d/usr.sbin.mysqld

near the bottom like so:

...
/usr/sbin/mysqld {
    ...
    /var/log/mysql/ r,
    /var/log/mysql/* rw,
    /var/run/mysqld/mysqld.pid w,
    /var/run/mysqld/mysqld.sock w,
    /data/ r,
    /data/* rw,
}

And then make AppArmor reload the profiles.

# sudo /etc/init.d/apparmor reload
