Installation

Observium doesn't yet have a polished install system, so we've provided some documentation below. Please report any problems or questions with installation to adama (a) memetic.org

We highly recommend doing an SVN installation. We develop and test on Ubuntu/Debian:

• Ubuntu SVN Installation -- Use this to keep up to date with all changes. (Also follow this for Debian)

Unofficial installation guides. These are likely to be wrong and/or out of date. We will not provide any help for anything other than Ubuntu/Debian.

• CentOS SVN Installation -- Use this to install the most recent stable release on a CentOS distro.
• FreeBSD SVN Installation - Use this to install the most recent trunk version on FreeBSD
