This post is mostly for my own reference, just in case I need to rebuild a server and want to save myself the Googling. These links helped: Nagios Core 3.x Docs – The quick-start guide was great. I recommend compiling yourself instead of using yum so that your paths match […]

I recently noticed that my /boot partition was at 95% full, so I investigated to see what was causing it. Apparently, it was filling up with older versions of the linux kernel as a result of upgrades. Because my system has been very stable, I decided to keep only the […]
Removing Old Kernels on Fedora, RHEL, or CentOS with Yum
For about a year now, we’ve been happily running two Dell PowerEdge 2950s with quad procs, 4GB of RAM (or so we thought), and RHEL5. Running a high-traffic website can be memory intensive, so we recently decided to upgrade the memory, and bought 8 more GB of RAM for each […]
