Red Hat Enterprise Linux is a subscription based distribution aimed at commercial users. Slicehost offers RHEL as one of its distributions.

These RHEL tutorials take you from a 'barebones' Slice to a secure, up to date and steamingly quick Slice in very little time.

RHEL Setup:

RHEL 5.4 Setup - Part 1: Your RHEL 5.4 Slice will be a bare-bones install when it's created. We need to connect via SSH and secure it as soon as possible.

RHEL 5.4 Setup - Part 2: Now that we've secured access to our RHEL 5.4 slice we can update it and get it ready for the rest of the server install.


RHEL 5.3 Setup - Part 1: Your RHEL 5.3 Slice will be a bare-bones install when it's created. We need to connect via SSH and secure it as soon as possible.

RHEL and Munin:

Installing munin on RHEL: Anticipating problems and resource shortages on a slice can be more valuable than fixing them after they've happened. A monitoring tool like munin lets you watch your slice's resource use over time. The graphs will highlight issues before they cause downtime or bandwidth quota overages.

Munin configuration and testing on RHEL: This article continues the installation and setup of munin on a single slice. It explains how to determine or change the URL used to access munin's reports and then check to make sure those reports are viewable and being updated.

Installing additional munin nodes on RHEL: Following up on the article about installing a munin master slice, if you want to monitor additional slices you'll need to install a munin node service on each.

Enabling munin node plug-ins on RHEL: Munin uses plug-ins to determine what data is gathered and reported. It includes several plug-ins for the types of data most people would be interested in, but not all of those plug-ins are enabled on a fresh installation.


The Kernel:

Using pv-grub to run custom kernels on RHEL - preparing the slice: The pv-grub kernel option allows your RHEL slice to boot from your own kernel instead of one of ours. Before you can try it out you need to prepare the slice with some config changes.
