CentOS 5.6: The Reliable Server OS Gets a Revamp

CentOS is the most popular Linux distribution used for web servers, running around 30% of the world’s Linux-based websites, according to a survey by W3Techs. CentOS is built from the freely available sources for Red Hat Enterprise Linux 5.6 and supports 32- and 64-bit x86 architectures. Since it depends on Red Hat releasing the sources, CentOS is always behind the current Red Hat release, but it remains a trustworthy server solution. System administrators familiar with any of the CentOS 5 releases will feel immediately at home with this release.
