I am trying to setup an ispconfig web server on RHEL 6.1 using your guide at: http://www.howtoforge.com/perfect-server-centos-6.0-x86_64-ispconfig-3-p3 Everything was going fine until I attempted to install yum-priorities and httpd and some other packages. The error I get is: yum install httpd Loaded plugins: product-id, subscription-manager Updating Red Hat repositories. Setting up Install Process No package httpd available. Error: Nothing to do The package repositories in /etc/yum.repos.d/epel.repo do not have an httpd package listed in them. What am I missing? Which package repository should I add for this? I am so new to yum, we are migrating from our old suse servers and I haven't used yum before, but it seems simple.
