A better way to install MongoDB on Ubuntu
My last post on installing MongoDB on Ubuntu is quite popular. Sadly, they aren't the best, or the most up to date installation instructions. While I don't really mess with MongoDB anymore, I feel a little bad with so much traffic coming from Google to those outdated instructions. In fact, it's super easy to install MongoDB on an Ubuntu server these days.
Basically, all you need to do is add a new source to your /etc/apt/sources.list. For the latest Ubuntu (10.10 at the time of this post), you'll add:
deb http://downloads.mongodb.org/distros/ubuntu 10.10 10gen
Once you've added the new source, you'll need to import MongoDB's public GPG key in order to download from the official servers:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
Once that's done, run sudo apt-get update and then sudo apt-get install mongodb-stable to get the latest stable release. Once installed, you can configure via the configuration file at /etc/mongodb.conf.
The full instructions, including the source URLs for older Ubuntu/Debian versions, can be found on the MongoDB website.
Edited 12/15/2010: Added the GPG key step.
