Centos 5.6 or 6.0

6.0 has newer software, both are equally delayed in updates, so unless you have to maintain legacy 5.x, I see no reason not to switch to 6.0

Thanks, what's the important thing for web server ? Centos 6 has newer software, which is Apache, PHP or Mysql?

I think the less resource(memory requirement and CPU) more reliability is the important for web server.

By the way, I find that Rackspace's newest Linux Distributions is CentOS 5.6 not 6.0.

Any first hand experience for this question?

The major difference is that CentOS 5 will be end-of-life in March 2014, while CentOS 6 will be end-of-life in November 2017. For a new installation, I wouldn't use CentOS 5.

(I wouldn't use CentOS 6, either, but that wasn't the question.)

Let the distro wars begin (again)! :)

Please note: Linode 768

Centos 6 installer needs at least 392MB of memory to work.

Text mode will automatically be used if the system has less than 652MB of memory.

Then again you're not installing CentOS 6 yourself. You can't, but even if you wanted to, you can upload a pre-installed image yourself, so in any case you're never going to use the installer on the Linode.

Just select the preinstalled image from the drop-down menu when you create new linode.
