NixCraft - Linux Administration

Here is a great Linux Admin blog with plenty of content for the both the beginner and the advanced Linux Admin. The name of the blog is nixCraft and it has been in my RSS reader for a while, and I wanted to share with you a couple of the scripts and links that I pulled out and have used.

The first is a quick and easy MySql database backup that you can put in cron to backup your MySql database. Many open source projects use MySql and it always pays to have a backup especially when upgrading, so take a look at this post called backing up your mysql database server.

The second script is a rsync replication script that we use between a couple of clustered web servers. The script is called resync backup replication script.

And the last example is for the beginner administrator. This post identifies a number of Unix/Linux commands and cheat sheets that was worthwhile to the new administrator.

If you are into Linux from a support or development perspective than I encourage you to take a look at the nixCraft site as I am sure that you will find something useful.
