Installing PostgreSQL 8.4 on Ubuntu 11.04

I am working on getting evergreen-ils running on a test server for later use.

The Evergreen Project develops an open source ILS (integrated library system) used by approximately 800 libraries.  The software, also called Evergreen, is used by libraries to provide their public catalog interface as well as to manage back-of-house operations such as circulation (checkouts and checkins), acquisition of library materials, and (particularly in the case of Evergreen) sharing resources among groups of libraries.

The Evergreen Project was initiated by the Georgia Public Library System in 2006 to serve their need for a scalable catalog shared by (as of now) approximately 250 public libraries in the state of Georgia.  After Evergreen was released, it has since been adopted by a number of library consortia in the US and Canada as well as various individual libraries, and has started being adopted by libraries outside of North America.

To get Evergreen Running, I have to do a lot of work on my server.  Since I am taking notes as I go, here is the transcript of those notes.  Where I am using passwords, I will instead use the convention of <secret>, so instead of saying “My password is T^T87uugf7h,” I will say “My password is <secret>.”  Things behind a “#” sign are comments – either comments in the files themselves or notes to my readers

The first thing I had to do is set up postgreSQL.  I had it set up a while ago, but I couldn’t remember any of the configurations I had done or the passwords or the users, so it seemed like the best solution was to completely remove it and start again.

  1. Hi Zamphatta!
    Glad I can help.
    I am upgrading Ubuntu 10.04LTS servers from Postgresql-8.4 to Postgresql-9.0. This is a bit more complicated when there are already databases with real data sitting on the 8.4 installations. You cannot just add the backport repository that gets 9.0. That breaks the existing databases. As soon as I have that sorted out (with lots of help from Dan Scott at I will post it as well.
