Building a uWSGI Emperor for multiple python versisons
September 5, 2015
This is a quick update to my tutorial on hosting Django Apps on Ubuntu with Nginx and uWSGI. I recently wanted to move to a mix of Python 3.4 and Python 2.7 web apps on one of my servers that was set up as described in that tutorial. Here's how to do that.
Normally, I just install uWSGI using pip. The big downside of that approach is that it only builds uWSGI for the version of Python with which you install it. So to get one emperor that can run apps (vassals) with different versions of Python, we need to compile uWSGI. Luckily it's really easy.
Here is an example of the required steps. Just run the following commands as root.
