I wrote some install scripts for an eloipool private pool and they seem to be in working order for Ubuntu 12.04. The only thing that makes it a private pool is the eloipool config file, which can be swapped out.
Everything gets downloaded and installed into one directory, but it does use the package manager to install a few support files. I'm running it out of my home directory, but you could easily run it out of /opt.
Thanks to everyone for helping me test the scripts.
I'm A machine in accordance with the documentation for the installation and configuration, but in the B machine can not connect to the server, it can be configured to give me a copy of your reference under it?
