MySQL 5.5 service won't start: Job failed to start

Trying to connect to my local MySQL 5.5 on an Ubuntu Server 12.10 x64 gave me the following error:

   levente@linuxvm:/$ mysql
   ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

Turned out that the MySQL Service is not running.

   levente@linuxvm:/$ ps -ef | grep mysql
   levente 5347 2842 0 08:47 pts/1 00:00:00 grep --color=auto mysql

Trying to start it failed:

   levente@linuxvm:/var/log$ sudo service mysql start
   start: Job failed to start

Syslog shows like this:

   levente@linuxvm:/$ cat /var/log/syslog

The problem is that I had some incorrect values in /etc/mysql/my.cnf. In my case it was an incorrect bind address that I just uncommented.

  #
  # Instead of skip-networking the default is now to listen only on
  # localhost which is more compatible and is not less secure.
  # bind-address = 172.17.1.1
  #
  levente@linuxvm:/$ sudo start mysql
  mysql start/running, process 5432

Yay!
