Since the official release of IBM Notes and Domino 9.0 Social Edition a few weeks ago, I have been "chomping at the bit" wanting to release a set of instructions / videos on how to install it on a Linux machine.
During the beta program I had the opportunity to "play" with it quite a bit, and let me tell you this release is exceptionally good. It is also by far the easiest and most hassle-free version I have ever installed on a Linux machine -but there are still a few gotchas and watch-outs to be wary of.
I have written an instructional document entitled Installing and Configuring IBM Domino 9 Social Edition on CentOS 6 Enterprise Linux. I hope it helps alleviate some of the fear and confusion with regards to using Linux as your Domino server platform. The document is aimed at YellowHeads (having some experience with Domino installations on Windows) who are thinking about stepping into the world of Linux. The document is focused on 64 bit Linux, but calls out differences from 32 bit installations where necessary. Even though it is aimed specifically at CentOS 6, the instructions should work for any RHEL or Debian-based (with some changes to handle DEB vs. RPM) linux version -although I must point out that the only supported Linux distributions are RHEL 6 and SUSE 11.
I have also cut a series of 9 videos wherein I walk through the instructions step-by step and demonstrate how easy it really is to perform the installation. They are available on my YouTube channel, although I'm hoping I can talk David Leedy into including them on Notes In 9.
Hope this helps!-Devin
