hi. I compiled versions 5.3.4 and spent way too long trying to figure out why my site was off-line. I finally came to the conclusion that for some reason php will not connect to mysql. Apparently in the settings.php I had to change localhost to 127.0.0.1.

Anyone know why this is? I am aware of the windows bug where mysql/mysqli will not connect if you use localhost but this is the first time I experienced this on centos. Does anyone know how to get localhost to work again? This issue only affects php connections to mysql as anything else like proxy and memcache connections are not affected.
