I 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.
Install vSphere CLI in CentOS 6
0I recently installed VMware’s vSphere CLI 5.1 tools on a CentOS 6 x86_64 VM. Despite the rather reassuring documentation released by VMware, installing these tools was no simple task. I will outline the steps that I took for a successful installation of the vSphere CLI software, as some of it is not very obvious, especially for beginners.

RHCSA Study Guide RHEL 6
0If you are considering obtaining a certification in Linux to advance your career, a great certificate to hold is the Red Hat Certified System Administrator (RHCSA). Red Hat is the premier enterprise Linux distribution, used in countless production environments worldwide. Red Hat certifications require a candidate to sit for a practical exam; there are no multiple choice questions, you must actually configure a live system.
Please excuse the formatting of this post. I am working to clean it up.
Throughout the web, you can find a collection of study guides for the RHCSA. I have created my own, which is a collection of my own notes and the notes of others. I highly recommend using the following book:
RHCSA/RHCE Red Hat Linux Certification Study Guide (Exams EX200 & EX300), 6th Edition (Certification Press)
Current exam objectives can be found here: http://www.redhat.com/training/courses/ex200/examobjective

Fedora 18 Review
2
Fedora 18 was released in the middle of last month without too much fanfare. I suspect this is likely because the beta was extremely buggy; many people had trouble installing Fedora 18 Beta using the new Anaconda installer interface, and I myself even filed a bug report for GRUB2 not loading after installation (which is still outstanding).
Why should you be interested in Fedora 18? Well, aside from the fact that it’s already a very popular desktop distro, according to this article from ServerWatch.com, Fedora 17 and Fedora 18 will debut some of the features slated for release in RHEL 7, which is due out within the next year or so.
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…)
