Ubuntu Karmic Koala Slices
Ubuntu 9.10 (Karmic Koala) is the eleventh release from Ubuntu. Note this is not an LTS (Long Term Support) release and will receive support from Ubuntu until April 2011.
These Ubuntu Karmic Koala tutorials take you from a 'barebones' Slice to a secure, up to date and quick server in very little time.
Ubuntu Karmic Setup:
Ubuntu Karmic Setup - part 1: Your Ubuntu Karmic Slice will be a bare-bones install when it's created. We need to connect via SSH and secure it as soon as possible.
Ubuntu Karmic Setup - part 2: Now that we've secured access to our Ubuntu Karmic slice we can update it and get it ready for the rest of the server install.
Understanding logrotate on Ubuntu - part 1: It's no fun when log files grow out of control. In this two-part series, learn how to use logrotate to keep those logs in check.
Understanding logrotate on Ubuntu - part 2: In this second part of the logrotate series we look at how to set up rotation for virtual host logs, as well as some troubleshooting techniques.

Apache configuration files on Ubuntu: Let's take a look at where apache's config files wind up when installed with the Ubuntu package manager.
Configuring the Apache MPM on Ubuntu: Now that you know where the files are, let's look at how to tell apache to stay within the memory available to your Ubuntu server.
Apache configuration on Ubuntu - part 1: Your Ubuntu web server continues to take shape as we delve into the depths of apache's configuration options.
Apache configuration on Ubuntu - part 2: We continue to look at apache configuration options for your Ubuntu server.
Apache Virtual Hosts on Ubuntu - part 1: Now that apache is running and configured on your Ubuntu server we can add virtual hosts to let it serve more than one domain.
Apache Virtual Hosts on Ubuntu - part 2: With the base apache virtual host configs in place on your Ubuntu server, let's look at other settings you may want to apply to them.
Barebones apache install for Ubuntu: How to set up a basic, no-frills apache server. Recommended for experienced admins only.

Configuring MySQL server on Ubuntu: We continue our MySQL server setup for Ubuntu by looking at configuration options to try and ensure the server doesn’t just run, but runs smoothly.
Basic MySQL server tasks: Even the most basic MySQL server installation for Linux will have you performing basic administrative tasks like creating users and granting permissions. We look at some of those tasks here.
Network Time Protocol
Using NTP to sync time on Ubuntu: Keeping your Ubuntu system's date and time accurate is easy to do using NTP.
Ubuntu Karmic and Munin:
Installing munin on Ubuntu: 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 Ubuntu: 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 Ubuntu: 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 Ubuntu: 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.
Downloading and using kernel source code (18.104.22.168 and newer) on Ubuntu: If you know you need to get your kernel source (or at least its headers) for a kernel version 22.214.171.124 and newer, you can find instructions to do so on Ubuntu here.
Using pv-grub to run custom kernels on Ubuntu - preparing the slice: The pv-grub kernel option allows your Ubuntu 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.
Using pv-grub to run custom kernels on Ubuntu - enabling and troubleshooting: Make the final changes to enable pv-grub for your Ubuntu Linux VPS, then check the results.
