Server Administration
Minotaur trailer We are now running on the new production server. This is the second server we have successfully configured to generate the map. A quick list of the major components:
- Mapnik – the geographical rendering engine.
- Tilecache – caches the tiles for speedier performance
- PostgreSql – the database
- PostGIS – the database plugin that supports spatial data
- phppgadmin – used to help administer the database
We are both getting a lot better at Linux server administration, setting up security groups and samba shares and getting the static IP addresses set up is getting easier. Our development environment was a Ubuntu 8.04 32bit machine that is just about 6 years old, needless to say we were in need of something new. Our new box is a Virtual Machine (Host is Windows Server 2008, running Hyper-V, but more on virtualization later) and it’s running Ubuntu 8.10 64bit on a machine that has four processors and 4Gb of ram, it’s quite the improvement. We are going to be soft launching the map this week to select number of folks, and then we will fixing bugs, gathering feedback and looking forward to our official beta launch in early February.
We also just went though the process of rebuilding our subversion/bugzilla/development server which also runs on Ubuntu Server, As of this point we have configured four Linux servers (all Ubuntu Server). Not bad for a shop where Open Source was a bad word and server was synonymous with Windows.
