Server Monitoring With munin And monit On Debian Etch

Post date: May 13, 2007, 21:05 Category: System Views: 3633 Comments
Tutorial quote: In this article I will describe how you can monitor your Debian Etch 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 let 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.

How To Back Up MySQL Databases Without Interrupting MySQL

Post date: May 12, 2007, 23:05 Category: System Views: 3416 Comments
Tutorial quote: This article describes how you can back up MySQL databases without interrupting the MySQL service. Normally, when you want to create a MySQL backup, you either have to stop MySQL or issue a read lock on your MySQL tables in order to get a correct backup; if you do not do it this way, you can end up with an inconsistent backup. To get consistent backups without interrupting MySQL, I use a little trick: I replicate my MySQL database to a second MySQL server, and on the second MySQL server I use a cron job that creates regular backups of the replicated database.

By supporting this protocol, Samba allows Unix servers to get in on the action, communicating with the same networking protocol as Microsoft Windows

products.

Back Up Linux And Windows Systems With BackupPC

Post date: January 28, 2007, 21:01 Category: System Views: 4278 Comments
Tutorial quote: This tutorial shows how you can back up Linux and Windows systems with BackupPC. BackupPC acts as a server and is installed on a Linux system, and from there it can connect to all Linux and Windows systems in your local network to back them up and restore them without interfering with the user's work on that system. On the clients minimal to no configuration is needed. BackupPC supports full and incremental backups, and it comes with a neat web frontend for the administrator and normal user so that backups and recoveries can be managed through a web browser. It should be noted, however, that BackupPC does file-based backups, not bit-wise backups like Ghost4Linux, for example, so it is not made for disk/partition imaging.

A Beginner's Guide To LVM

Post date: January 16, 2007, 19:01 Category: System Views: 3679 Comments
Tutorial quote: This guide shows how to work with LVM (Logical Volume Management) on Linux. It also describes how to use LVM together with RAID1 in an extra chapter. As LVM is a rather abstract topic, this article comes with a Debian Etch VMware image that you can download and start, and on that Debian Etch system you can run all the commands I execute here and compare your results with mine. Through this practical approach you should get used to LVM very fast.

Disk ARchive (Backup and Restore) using dar and kdar(dar Frontend)

Post date: January 12, 2007, 18:01 Category: System Views: 3477 Comments
Tutorial quote: Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, CDs, ZIPs, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links and extended attributes, remote backup using pipes and external command (such as ssh), and rearrangement of the “slices” of an existing archive. It can now run commands between slices, encrypt archives, and quickly retrieve individual files from differential and full backups. Dar also has external GUI like kdar for Linux,thanks to the well documented API.
