My colleague Charles Price has created two guides covering the installation of IBM Connections 5.0, CR2 and IBM Docs on Linux. While I have created guides like that before, I have always done them on Windows, as Linux is, for me at least, a different kind if beast that I have so far avoided as much as I can. 😉
Here you go:
Installation guide IBM Connections 5.0 on Linux
Installation guide IBM Connections 5.0 CR2 on Linux
Installation guide IBM Docs 1.0.7 on IBM Connections 5.0 CR2 on LinuxÂ
 In the last one I especially like the two topics of upgrading CCM for Docs as well as the description on how to configure either NFS or CIFS shares.
