Several problem with MySQL

[fodinabor]

Hey Guys,
I have some problems with my Plesk 11.5 using MySQL:
1. I can't login to Plesk:

ERROR: PleskFatalException: Unable to connect to database: saved admin password is incorrect. (auth.php:149)

2. I can't restart MySQL:

service mysql restart
[FAIL] Stopping MySQL database server: mysqld failed!
[ ok ] Starting MySQL database server: mysqld already running.
[info] Checking for tables which need an upgrade, are corrupt or were 
not closed cleanly..
root@name:~# ERROR 1045 (28000): Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)

3. I also can't login to MySQL per SSH (only in skip-grant-tables mode, but when I try to change my passwort as in http://kb.parallels.com/en/112492 described it don't affect any rows, I do have to change the user to root, but it doesn't help to solve the problem)

The changes I can remeber, I did before it chrashed: I installed GitLab

My System: Debian 7.4, MySQL 5.5, Plesk 11.5

I hope you're able to help me,
- Joachim

Do you have /root/.my.cnf file?

Hi,
nope as well as I see I only do have those files:

/etc/mysql/my.cnf
/etc/mysql/my.cnf.bak
/etc/mysql/my.cnf.prep

Content of /etc/mysql/my.cnf:
http://pastie.org/8988511

I hope this gives an idea what's going wrong

Greetings
