I am trying to install RoundCube webmail application on my Arch Linux LAMP server. I have everything installed and running fine as far as I can tell. Postfix and Dovecot work perfect using my Thunderbird client but I need to access the email server from home. I have an index.html page configured in /srv/http that I can access from anywhere in the world with an Internet connection. I finally installed PHP and MySQL. I tested PHP from Apache and it appears to be working great. I started MySQL and locked down the root user fro MySQL and created a generic user and database for 'RoundCube'. Now when I go to the RoundCube web installer, it does not detect any running databases on my server. I don't understand why? I followed the directions perfectly and when I try the same thing on a CentOS server, it works. Here is the screenshot showing the installer detecting PHP but not MySQL. If MySQL is running, why would this not be detected...???
