For some reason, I can't start MySql.
$ sudo /etc/init.d/mysql start
[sudo] password for abigail:

What caused this?
This is what in my /var/lib/mysql
$ ll -h /var/lib/mysql

I think I might have to reinstall mysql.
my.cnf is supposed to be in /etc/my.cnf.
Check the start log for the error message, like in /var/log/mysqld.log.
One of our MySQL servers died but somehow we were able to recover all the files from it. This server was a slave at one time however we stopped it being a slave so we could use it for housekeeping tasks and reports, etc.
Can someone tell me how to recover with this?
I now have these files and a backup of my.cnf

Where do I find logs about GTM command like : SET ^,WRIRE....?
Normal commands (Set, Write) are part of the core programming language and are not logged; they are journalled if they read or write something to disk. The question is what are you looking for?
I'm pretty lost right now.
The RAID controller auf my server broke and all attached hard drives were corrupted. Luckily I copied the plain files off the server right before the crash (phew).
I set up the new server with Ubuntu 12.04 and a fresh mysql installation. I copied the backup off a server directly to the new one, without saving them to a windows machine (to prevent privileges errors).
My back up folder looks like this:
drwx------ 15 jensma jensma 4.0K Dec 12 18:09 .

I just copied the whole content to /var/lib/mysql and ran
sudo /usr/sbin/mysqld –innodb_log_file_size=5242880 –innodb_force_recovery=6
Well, the command kinda works - the shell shows up after half a minute. But the database is still empty :/
I'm pretty now to this. I do have full admin access to the server.
Any help is appreciated, thanks!
I see today that
show databases
displays an unknown database:
(msl_ampcs_v4_0_0_2g)> show databases;

| Database |

Normally when I see something like that it is due to a bad file in /var/lib/mysql:

But nothing like that is present. The nohup shouldn't be there. But
#mysql50#.ssh
does not appear.
