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 [...]

dnsmasq is a lightweight, open-source DNS forwarder and DHCP server. In this article we go through how to prepare the system in order to run dnsmasq and also how to configure the latter as a caching-only DNS server. A configuration file is also provided as a drop-in replacement for the default dnsmasq.conf that ships with [...]

The last incident with the php-cgi errors as a result of a bad PHP script made me re-evaluate the daily reports I receive from the server. I realized that a report about the httpd errors that have occured during the previous day, including all virtualhosts, is more important than I had initially thought. Such a [...]

This is just a quick notice that during the last five days there was a problem with the website feeds. The web server returned a 500 Internal Server Error to almost all requests for /feed/ URLs. Also, there was a big increase of the server’s CPU load behind the scenes, which was caused by php-cgi [...]

I am afraid the deployment of Redmine on CodeTRAX.org will be delayed some more. This is because I am skeptical about using mod_fcgid to run two different kinds of web applications on the same web server. This software is pretty much incomplete when it comes to defining classes of applications and setting limits, like the [...]

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 [...]

CentOS 5.3 for the i386 and x86_64 architectures has been released today. I usually do not reproduce such announcements, but this CentOS release is somehow special to me.

I’ve been using the mod_dav_svn module for Apache, part of the subversion distribution package, in order to make several SVN repositories available over the HTTP protocol for quite some time now. More specifically, I use a multi-repository setup under the same virtualhost by using the SVNParentPath directive of mod_dav_svn. Also, the authorization policy is enforced [...]

I’ve used the phrase “writable by the webserver” numerous times throughout this blog, without ever bothering to explain in detail what this means. Yesterday, I received an email asking me exactly that, so I decided to finally write a post about it and use it as a reference whenever I use the aforementioned phrase. I’ll [...]
