Plesk is very finicky about the versions of software you install<br>and very jealous of its own configuration file.<br><br>So, once a server is running Plesk, it controls everything from <br>Apache to MySQL to PHP. You can't modify a setting in Apache.
<br>Plesk will roll it back for you in few minutes.<br><br>This means tuning things on a Plesk server is a pain. It also<br>means you cannot upgrade things from RPMs, ...etc.<br><br>While the motivation behind this is understandable (they own
<br>the configuration, so they only install their own sanctioned <br>versions of the software and disallow you from changing it),<br>it makes life so much harder if you want to upgrade something<br>or install an accelerator, or tune something.
<br><br>So, this "fun" way will now extend to Drupal? Great. Means<br>more headaches for the clients and consultants.<br>
