All kinds of errors. MYSQL will not start and 500 error.

Postby jaykai » 21. October 2011 20:04

I woke up this morning to check on our server and make some changes and after restarting, MYSQL will not start and now I'm getting a 500 internal error. I also checked all permissions and everything in that folder is 777. This is driving me crazy. I booted from a backup, which also had this error, so I don't know what to do. :?: Any help would GREATLY be appreciated.

Here's the error from the log:

My "guess" only is that you had some disk problems.

Note that line:
"111021 14:51:28 mysqld_safe Starting mysqld daemon with databases from /Applications/XAMPP/xamppfiles/var/mysql
Warning: World-writable config file '/Applications/XAMPP/xamppfiles/etc/my.cnf' is ignored

I don't have a Mac, BUT I believe I can think through how to find to what the deal is on MySQL
Consult the XAMPP for Mac OS X page > Where to find things
/Applications/XAMPP/etc/my.cnf

This tells JonB that things are 'fouled up' in XAMMPville on your machine. Its passing over the file it should be reading for the configuration.

http://www.apachefriends.org/en/xampp-macosx.html

The ISE 500 error happens "when" you do "what"????

Now - what's wrong??? As I said before things could be fouled up on the disk. It could also be that your restoration has tangled the ownership and/or permissions of critical files. After all, despite what SJ may have convinced everyone, OS X is really a very advanced shell for BSD (derived form NextStep) - thus all those Unix filesystem thingies ARE actually important.

1st - I'd try to answer two questions - What exactly still works, and what does NOT work.

2nd - I'd look for some good Mac-specific advice on checking your filesystem & disk.

3rd. - Before you restored, you DID get a backup of how things were, right???

4th. - It would be valuable to describe how the 'backup' was made, and how it was 'restored'

Good Luck, and I hope you have already located the problem, and my advice is unnecessary.
