Restore original configuration files from RPM packages

By default, when the user installs software through the RPM Package Manager or through YUM, usually, the software’s configuration files included in the RPM do not replace the existing configuration files on the filesystem, but, if they differ from those that currently exist, they are saved with the rpmnew extension. In case the rpm is [...]

Running supervisor 3 on CentOS 5

It’s been a long time since the last time I checked the available software for managing long running processes. Software in this particular area has evolved and, after some research and testing on a virtual machine, I tried to install supervisord in a CentOS 5.6 box. Unfortunately, no RPM package exists for the latest 3.X [...]

RHEL kernel source released with patches already applied

Red Hat used to release its kernel SRPM package including a tarball of the vanilla kernel sources and a set of custom patches.

Usually, the only time I make a change to the timezone setting of the operating system is during the installation time. But it may happen that a change to that setting is necessary. There are several ways to do this, but, as usual, there is only one Right Way™ to set the timezone info in [...]

Fedora Server vs CentOS

End of era for my Fedora based server after almost five years of service. The box now runs CentOS. I had this box at home and it was the only Fedora Server I ever maintained at home or elsewhere. I should state from the beginning that it was only Fedora’s short life-cycle that practically forced [...]

YUM-Priorities Configuration for a CentOS Desktop

When it comes to software for your CentOS installation, there is no such thing as a good yum configuration, but a configuration that can bring you the software you need, while, at the same time, causing the least possible trouble regarding core package upgrades. This small article goes into the details of configuring YUM using [...]

Sticking with CentOS, RPMforge and yum-priorities for now

Having spent some days with CentOS on my desktop and having tried several 3rd party RPM repositories, I’ve finally decided to mix the official repos (base, updates, addons, extras) with RPMforge and also make use of the priorities yum plugin. Read on if you care about the details…
