Can't find my.cnf file so I can enable InnoDB - is there another way?

I am trying to Magento running on a share server, and am having difficulty.

When I look at the engines in PHPmyAdmin, I get InnoDB DISABLED. So 开发者_JAVA技巧I look in /etc/, and there is no my.cnf file.

There is a ftpquota and a .boxtrapper file, but nothing else.

I know I can probably create a new one, but this is a server that hosts a lot of sites. I'm afraid I will mess someone up.

So is there a way to maybe create a my.cnf file that only enable InnoDB and doesn't effect anything else? Or is there another way to enable it?

Check ps -ef to see where the location of mySQL is - on some servers, it may also show the location of the configuration file, which may (or may not) be writable for you.

If there's no my.cnf file, it's possible to create one and upon restart MySQL will use it.

However, you said it's a shared server? I'm afraid that your hosting provider has chosen to disable it because they want to be cheap (and save memory).

See my related answer here: Is INNODB enabled by default in MySQL?

It's (very) unlikely you will have permissions to override what your hosting provider has done.
