I inherited about two years ago a reseller account on a VPS (overseas network admin vanished).
I've been using it, learning as I go, the basics of setting up and managing accounts (I have approximately 12 virtually hosted accounts under it now (ie different domains) with some domains having a few sub-domains under them. I run mostly Joomla 1.5 and now 1.7 sites on those accounts.
I have full (shell) access on the account.
At present, this VPS is running:
cPanel 11.24.5-R38506 - WHM 11.24.2 - X3.9
CENTOS 5.3 i686 virtuozzo on vps
I'm looking for some help on what basic maintenance and upgrade tasks I should be doing (for example, updating cPanel and WHM versions, updating PHP and MySQL versions, cleaning caches, shutting down and restarting services to 'freshen' things up, etc.. Also would like some hints as to which logs are typically monitored, why and how.
I realize this is a broad question but there must be some basic approaches to this.
