Learn some basic sysops on Linux. Start with using basic package management (apt-get), and then move on to learning how to configure apache (ssl, vhosts, vhost redirects, location, directive etc).

You can build on the first part easily if you switch to something like Ubuntu. Learning apache can only come if you force yourself to manage multiple virtual-hosts or sites. Handling apache is quite similar to using the htaccess file (which you might have used for redirects) except you have much more power in vhosts.
