At my day job, I’m a Linux System Administrator. This roughly translates to “Everything System Administrator” as I work in a lot of other capacities as well. One of my duties is maintaining an internal web portal that runs on a RHEL 6 system. A good portion of our portal runs on Python and Perl CGI scripts. I wanted to dynamically update part of a page and I needed to make an Ajax call to a Python script instead of a normal PHP or ASP (etc). I ran into a problem with a not so obvious solution compared to how people make calls to PHP backends.
Centos 6 Apache Kerberos AD SSO
0I recently setup a RHEL / Centos 6 Apache websever at work that integrates with Active Directory (AD) and Kerberos for a single sign on (SSO) web resource. This took me a lot more time than I thought it would, but that’s because the tutorials I was reading were either wrong, or didn’t apply to my situation. I am outlining the steps I took below to help others who may wish to have a similar setup.

Backup MySQL database
0Today, we’re going to be covering the 3 most important rules for any Linux System Administrator: Backups, Backups, Backups.
That’s right, if you don’t have backups, you have failed in your duties. Every single thing else you may have done to secure your system cannot replace the need for backups. Systems get cracked, hard drives fail, CPUs fail, RAM fails, password are forgotten, files get rm’d by mistake, patches break systems.
This article is about creating a simple backup script to backup your MySQL databases to an offsite location, complete with cron jobs, and encryption.
Install Magento in Debian Linux
1Magento is a freely available shopping cart / ecommerce solution in production use all over the internet. In this article, I’ll be outlining the steps to install Magento Community edition in Debian Squeeze. It’s really quite simple if you’re using Apache2. While NginX is supported by the latest release of Magento, the steps to install using NginX won’t be outlined here, but may be in another article in the future!
Configuring CentOS 6 Web Server
27
In this article, I’m going to be outlining the steps to install and configure a complete web server on a base install of CentOS 6. (Which should be compatible with Scientific Linux 6 as well as Red Hat Enterprise Linux 6)
I personally don’t prefer to install package groups relating to “LAMP” or similar during initial installation because I’m simply too lazy to review each and every package that is included in those groups, and what the dependencies are. By installing the required packages using yum, this allows you to install just the software you’re looking for, without worrying about dependencies. This software stack is time tested; we’ll install on CentOS’s latest release, and test a few popular applications while we’re at it! (more…)

The Ubuntu Web Stack
In this article, I’m going to be outlining the steps to install and configure a complete web server on a base install of Ubuntu 12.04 LTS server edition.
