This may be a noob question but there is something I have been trying to understand, there are currently three main versions of CentOS 4, 5, and 6. My main question is simply how do I know what version I should deploy? I have searched online and either I did not do a good job of searching or the information I get is inadequate. To better understand why I ask this question, here are some of the build up questions. - Is there an online resource that lists (compare/contrast) the different versions (i.e. 4, 5, and 6) and why you should pick a particular one? - Is a particular version the best for a web server, how do I know this? - Should or does it matter what version I deploy? - Can assume that once a version is decided upon, one should stick to the latest release. i.e. for version 5, go with 5.7 right now? If you can point me to an online resource, that would be awesome as well. B.I.
