Can't start server : Bind on unix socket: Permission denied
Do you already have another mysqld server running on socket: /srv/mysql/sockets/mysql-myDB.sock ?
Parece que o AppArmor é o culpado. Tente mudar isso:
/{,var/}run/mysqld/mysqld.pid w,
/{,var/}run/mysqld/mysqld.sock w,
para:
/srv/mysql/pids/mysqld-myDB.pid w,
/srv/mysql/sockets/mysql-myDB.sock w,
Eu tentaria apenas criar o socket e reiniciar o mysqlserver para ver se aquele chute começa.
touch mysql-myDB.sock
Verifique se é de propriedade do mysql.
Você está tentando executar duas instâncias do mysql ao mesmo tempo?

120222 13:43:53 [ERROR] Do you already have another mysqld server running on socket: /srv/mysql/sockets/mysql-myDB.sock ?

Isto significa que existe outro processo do servidor mysql sendo executado e escutando no soquete unix. Para confirmar, você pode usar:
sudo netstat -lnp | grep mysql
sudo lsof | grep /srv/mysql/sockets/mysql-myDB.sock
O mysql-myDB.sock é um arquivo de soquete. Não é um arquivo normal. Você não deve criá-lo usando touch . Você deve obter uma saída semelhante:
khaled@khaled-pc$ ls -l ls -l /var/run/mysqld/mysqld.sock
srwxrwxrwx 1 mysql mysql 0 2012-02-22 09:55 /var/run/mysqld/mysqld.sock
Veja o primeiro caractere s (socket) em ls -l output. Você tem - , o que denota um arquivo normal.
