    I've been using cPanel on Redhat Enterprise for some time now and am about to order my second cPanel server.

    My question is which os is the best for me to get? I'm quite happy with Red Hat but is there any real benefit of me paying the extra money for it over CentOS?

    My follow up question to this is that the new server is likely to be a could server with 4 CPUs and 4gb of ram, which I can increase at any time when I need to. Will getting CloudLinux benefit me in any way over the others? I realize that it allows me to set webspace with limited CPU and ram but will that make much of a difference in the long run?

    Hello,

    CloudLinux can limit set accounts for select services (such as PHP) from using up all the memory or CPU or a server. This means that account can be slowed down or unreachable due to using up beyond a set amount of CPU or memory. This can be very helpful with shared hosting in ensuring other clients aren't impacted by one high resource usage account. If you are going to be providing shared hosting even with a high number of CPUs and RAM, then you may want to investigate (by reading about it online) and consider CloudLinux.

    As for RHEL versus CentOS, RHEL has slight differences over CentOS, especially for RHEL 6 versus CentOS 6. RHEL has a company who handles fixing bugs and provides support for issues. If you want to have bugs fixed more quickly or to have someone you can contact when you need support for the OS, then RHEL would be the better choice. CentOS doesn't have that available, although they do have a process for handling bugs as well.

    Thanks!

    Great thank you.

    Just a couple more related questions.

    With Cloud Linux I take it that once a limit has been set to an account other customers can still use those resources are still pooled? For example if I have a 4 core server could I give 6 accounts each a limit of 1 core. They would all share but no one account could use more then 1 core in total at any one time.

    Finally the server I'm looking at has the option of a 25gb or 100gb first hard drive then whatever size I want for the second, third and fourth etc. My redhat server has a full install and uses just over 25gbs in total for the /boot, /var, /usr,/tmp and root partitions. If I was to install it on the first drive using the minimal os with cpanel, with those partitions, then the home directory on the second drive. Would the 25gbs be enough got it to run efficiently or would it cause issues? That question relates to both CloudLinux and Redhat / Centos options if it makes a difference.

    We recommend around 40GB total with at least 16GB for /var and 16GB for /usr and 2GB for /tmp partition. As such, I'd suggest having 40GB for the non-home drive and then the 100GB or more for /home for the second drive.

    Here's our partitioning recommendations:

    It sounds like my current server has them set up a little set a bit small.. I seem to remeber having to move some files around to make space at one point too. I think they were all set up by the Planet on the build of the machine. Hopefully they will let me choose how they are partitioned or at least do the cpanel recommended amounts..
