Staging

First, commit all local changes to the repository.

Next, launch a new staging server. On Amazon Web Services, for instance, launch a new EC2 instance. Remember that this configuration uses Ubuntu Server 12.04 LTS 64-bit (though other Debian-based Linux distributions should work fine).

The staging server will be almost identical to the production server. Most of the settings below will also apply in production.

Edit Configuration Settings

Change to the settings directory:

$ cd /path/to/virtualenvs/project_name/src/project_name/project_name

Edit the settings in production.py to match the settings for your staging server.

Next, change to the conf directory:

$ cd ../conf

Edit the following files and make sure the values are correct:

  • production.py: production deployment configuration
  • nginx.staging.conf: nginx virtual host configuration
  • launch.sh: a shell script to launch the Gunicorn server
  • livesite.conf: an Upstart configuration to launch Gunicorn on boot

Configure Staging Server

Once you’ve specified the settings above, Fabric will automatically configure the server environment. To configure the staging server, run:

$ cd .. # you should now be in the same directory as fabfile.py
$ fab configure_staging_server

Fabric will show the output of each command. You may be prompted for passwords (e.g., to log into the server or to clone the repository).
