nginx serving Django in a subdirectory through uWSGI

The nginx uwsgi_modifier1 is deprecated in uWSGI.

Your goal is to be able to host a wsgi app from anywhere without the app needing to be adjusted to account for where it's being served from.

The current method for doing this in uWSGI is to map mountpoints for each URI app combination like so:

[uwsgi]
socket = 127.0.0.1:3031
; mount apps
mount = /app1=app1.py
mount = /app2=app2.py
; rewrite SCRIPT_NAME and PATH_INFO accordingly
manage-script-name = true

Hosting multiple apps in the same process (aka managing SCRIPT_NAME and PATH_INFO)

mount can take the place of module

For Django specifically,

; Before
module = django_app.wsgi:application
; After
mount = /django_app=django_app.wsgi:application
manage-script-name = true

Cleanest Method for Latest Nginx/uWSGI Versions

Since uwsgi_modifier1 30 is removed in the latest versions and I felt like the mount-point stuff was too hacky, I had to use a newer method to serve Django in a subdirectory:

uWSGI config:

[uwsgi]
socket =        /tmp/project.sock

# Requires PCRE support compiled into uWSGI
route-run =     fixpathinfo:

Nginx config:

location /project {
    include         /etc/nginx/uwsgi_params;
    uwsgi_pass      unix:/tmp/project.sock;
    uwsgi_param     SCRIPT_NAME /project; # Pass the URL prefix to uWSGI so the "fixpathinfo:" route-rule can strip it out
}

NOTE: fixpathinfo: requires PCRE support to be compiled into uWSGI.

So if things aren't working, try installing libpcre and libpcre-dev, then recompile uwsgi with pip install -I --no-cache-dir uwsgi. uWSGI's internal routing subsystem requires the PCRE library to be installed before uWSGI is compiled/installed. More information on uWSGI and PCRE.
