Mysql was working, then I tried to move the MySql database directory as in this question which I already successfully used several times, but this time something went wrong and I got the error:

$ mysql  

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

so I re-installed mysql (several times as I kept getting that error), mainly with the following commands:

# ** uninstall:

sudo su

rm -r /var/lib/mysql # delete the database

aptitude remove mysql-server mysql-client mysql-common

apt-get autoremove

apt-get autoclean



# ** reinstall

apt-get install mysql-server mysql-client mysql-common

apt-get update

The disk is not full and I think think the problem is that at some point somehow I managed to get /etc/apparmor.d/usr.sbin.mysqld deleted and now I have the previous problem and also

$ service mysql status

mysql: unrecognized service

The disk is not full and if I reinstall mysql the file is not added. So, thanks to @AbrahamVanHelpsing I got the file from source, but the problem stills. Any ideas?

Thanks

Edit

aa-status did not mention mysql but it does now that I put the file that was missing.

Another edit

I can access mysql by running sudo mysqld and then mysql from another terminal, I still hope to register mysql in apparmor though
