XAMPP: Couldn't start MySQL! [Solved]

[T-362]

After adding new vhost and some time (i come today and its just dead, maybe not only "just dead" - other coder creates some new bases two days ago, but SQL server dies only after xampp restarting) -
Starting XAMPP for Linux 1.7.7...
XAMPP: Starting Apache with SSL (and PHP5)...
XAMPP: Starting MySQL...
Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored
XAMPP: Couldn't start MySQL!
XAMPP: Starting ProFTPD...
XAMPP for Linux started.

I used command from another topic -
[root@gn141 ~]# ls -l /opt/lampp/etc/my.cnf
-rwxrwxrwx 1 root root 5054 Dec 17 2010 /opt/lampp/etc/my.cnf
[root@gn141 ~]# chmod 644 /opt/lampp/etc/my.cnf
[root@gn141 ~]# ls -l /opt/lampp/etc/my.cnf
-rw-r--r-- 1 root root 5054 Dec 17 2010 /opt/lampp/etc/my.cnf

(my.cnf wasnt modified since install)
and now it just XAMPP: Couldn't start MySQL!

Also a httpd.pid file near the log with 11862 inside

What it can be? (And/or how i can reinstall xampp and save DBs and other stuff? And any good autobackup tool for xampp please.)

uhh permissions???

Warning: World-writable config file '/opt/lampp/etc/my.cnf' is ignored

what are the permissions currently on /opt/lampp/etc/my.cnf?

probably should be 644

Good Luck

Ok sorry we'v found a problem, another coder replaced MYSQL table with another one, its good that we have a backup .

-rw-r--r-- 1 root root 5237 May 7 11:16 /opt/lampp/etc/my.cnf

Backups are a developer's best friend.

Is your box back to working correctly or are you still getting errors?

[T-362]

Yeah all OK (except of some looses because of old table but its also ok)

OK, I'm calling this solved.

I'm sure you are aware you should fix your database(s) with the correct tools. LOL, as a System Architect that designs ground-up databases then integrates them with frameworks, I know that is easier said than done.

Good Luck
