Mysql won't start after reinstall

My server recently died (I think disk failure). Before it died (I think) I managed to dump the zimbra directory to a backup and tried to reinstall zimbra on a new machine (old and new machine were/are Release 7.1.4_GA_2555.RHEL5_64_20120105094627 CentOS5_64 FOSS edition). I used the method outlined here Backing up and restoring Zimbra (Open Source Version) - Zimbra :: Wiki and got it to go through (it took a few attempts).

The main issues seems to be that mysql is not currently running and won't start. When I installed I got:

Verifying integrity of message store databases. This may take a while.
Starting mysqld...failed.

And after the install I am still unable to get things working. Can anyone give me some guidance on how to get mysqld running. Thanks.

Edit: Here's /var/log/zimbra.log (with a few items edited out for privacy).

After I posted this message, the forums suggested some similar posts and I looked at one of those and found my problem (I had searched previously without success). I had edited the /etc/hosts file but I took out the line 127.0.0.1 localhost. Putting that back in fixed my problem. I think I need to check my database but aside from that it's up and running. Thanks zimbra forum for being a smarter searcher than I am.
