Will my two installations of MySQL conflict?

I have OS X 10.5.8 Leopard with developer tools, so it has mysql already installed in /usr/local/mysql. However, now I am going to use MacPorts to install my own MAMP stack instead of using the built-in one, so that I ca开发者_开发百科n have PHP 5.3. Do I need to reinstall MySQL using port? If so, how do I disable the old installation of MySQL so that they don't conflict?

You can use your existing MySQL installation. Of course you can run two instances. Just make sure they don't interfere in the port and/or socket configuration.

If you want to remove the existing installation, read this guide.
