InnoDB not enabled

I have a mysql database that when I run SHOW ENGINES; innodb does not show up as an engine.

This seems strange as I have an identical server setup where innodb is enabled and in use.

I have checked my.cnf, and there is no skip innodb line as many people have mentioned. I have also deleted my log files as another couple of people have suggested, but neither of these fixes have helped.

Any ideas? Any way I can start troubleshooting?

I've seen this issue before in my own set up it has to do mostly with trying to use a memory pool that is larger than your available memory. Check your my.cnf file to ensure your settings conform to your available memory.
