Why Scientific Linux?

For those who are familiar with my install guides, I have been producing Fedora install guides for many years. With recent Linux distributions, there has been a number of issues with the Access Grid software (particular ally since Fedora 14), with some testing pointing to versions of python-twisted causing some of the problems

 

Additionally, there is usually a new release of fedora every six months, with updates generally provided only for the latest 2 releases. Therefore, it is recommended that the machines are upgraded to the latest release each year. Whereas, the major releases for Enterprise Linux (Red Hat Variations) occurs only every few years. Thereby, available updates should last approximately five years. In an effort to reduce the constant “major re-install” of production systems, using “less cutting edge” operating systems that are based upon more stable and highly tested packages may be preferred.

 

In regards to Enterprise Linux, there are two popular free distributions, these being CentOS and Scientific Linux. Upon initial investigation on which distributions to use, Centos was “lagging behind” in providing releases, in which Scientific Linux had version 6.0 released and CentOS was still to be released. Additionally, Scientific Linux is developed and “put together” by various educational and research labs and universities. Therefore, the author will be focusing on using Scientific Linux.

 

It should be mentioned though, each distribution has their own advantages and but both very good. There are many discussions on the internet describing the pro and con’s on each.

 

Note: Anyone wishing to use the CentOS or RedHat Enterprise Linux distributions, should be able to use this guide as in many aspects, they are very similar distributions.

 

It should also be mentioned that RHEL 6, SL 6 and CentOS 6 are all generally based upon Fedora 13.
