http://serverfault.com – I can’t start MySQL on Ubuntu 12.04 after restored backup from innobackupex. Before I tried to restore the db from backup I moved the datadir and got the same problem. With help from google I fixed the problem and got MySQL started. Ready to set up my new slave, I restored the backup via innobackupex –-copy-path /db/mysql, and now I can’t start MySQL. I am sure of the following: In my.cnf the datadir = /db/mysql The new datadir is chown mysql:mysql. The /etc/apparmor.d/usr.sbin.mysqld contains: #/var/lib/mysql/ r, #/var/lib/mysql/** rwk, /db/mysql r, /db/mysql** rwk, AND (HowTos)
