If you don't already have easy_install available you'll want to download and run the ez_setup.py script:
$ curl -O http://peak.telecommunity.com/dist/ez_setup.py $ sudo python ez_setup.py -U setuptools
To install or upgrade to the latest released version of Gunicorn:
$ sudo easy_install -U gunicorn
You can install Gunicorn from source just as you would install any other Python package. Gunicorn uses setuptools which will automatically fetch all dependencies (including setuptools itself).
You can download a tarball of the latest sources from GitHub Downloads or fetch them with git:
$ git clone git://github.com/benoitc/gunicorn.git
$ python setup.py install
If you've cloned the git repository, its highly recommended that you use the develop command which will allow you to use Gunicorn from the source directory. This will allow you to keep up to date with development on GitHub as well as make changes to the source:
$ python setup.py develop
You may also want to install Eventlet or Gevent if you expect that your application code may need to pause for extended periods of time during request processing. Check out the FAQ for more information on when you'll want to consider one of the alternate worker types.
To install eventlet:
$ easy_install -U greenlet # Required for both $ easy_install -U eventlet # For eventlet workers $ easy_install -U gevent # For gevent workers
Note
If installing greenlet fails you probably need to install the Python headers. These headers are available in most package managers. On Ubuntu the package name for apt-get is python-dev.
Gevent also requires that libevent 1.4.x or 2.0.4 is installed. This could be a more recent version than what is available in your package manager. If Gevent fails to build even with libevent installed, this is the most likely reason.
If you use Ubuntu karmic, you can update your system with packages from our PPA by adding ppa:bchesneau/gunicorn to your system's Software Sources.
Or this PPA can be added to your system manually by copying the lines below and adding them to your system's software sources:
