Asking what the best Linux distribution for Zimbra, or basically any other software installation, is like asking who the most beautiful woman in the world is, or who is the greatest baseball player of all time. A lot of it is in the eye of the beholder, and you can start major arguments with this line of questioning.
You can go to the download page and see what distros have packages available. I personally recommend RHEL4 or CentOS 4 (free and basically RHEL unbranded). I have been running the Open Source edition of Zimbra on CentOS 4.4 for over a year, with the past five month being in a live environment. I currently have over 200 users and growing. The installation is straight forward; no real tweaks or anything like that to get Zimbra working. You just need to make sure you install all the prerequisites, which are all readily available. We haven't had so much as a blip on the server, and all upgrades have been perfect and easy.
Others can probably share success stories for the other supported Linux distros. While others still will probably say they've got Zimbra running on an unsupported OS with no problems.
Just my 2 cents. |
