Managing OpenVZ With HyperVM On CentOS 5.2

Managing OpenVZ With HyperVM On CentOS 5.2

HyperVM is a multi-platform, multi-tiered, multi-server, multi-virtualization web based application that will allow you to create and manage different virtual machines each based on different technologies across machines and platforms. Currently it supports OpenVZ and Xen virtualization and is available for RHEL 4/5 as well as CentOS 4 and CentOS 5. This tutorial shows how to install it on a CentOS 5.2 server to control OpenVZ containers. I will also explain how to manage OpenVZ containers with HyperVM on a remote CentOS 5.2 server ("slave").

Set Up A Linux PlayStation 3 Media Server (CentOS 5.2)

Set Up A Linux PlayStation 3 Media Server (CentOS 5.2)

The Sony PlayStation 3 is a DLNA compatible device, DLNA is a framework where home electronics can share digital media and content seamlessly. This tutorial is a followup to the previous howto on Ubuntu. Given that I like most others use CentOS as their server distribution of choice, I find it fitting to run my DLNA server on it as well. Although several other open source media servers exist, I chose to use Fuppes due to its ease of use as well as built in support for transcoding.

Server Monitoring With munin And monit On CentOS 5.2

Server Monitoring With munin And monit On CentOS 5.2

In this article I will describe how you can monitor your CentOS 5.2 server with munin and monit. munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
