Run Graphite behind uwsgi + nginx in a subpath/subdirectory/non-root path
View graphite.conf
# This is the config I used for nginx to proxy graphite via uwsgi to a non-root path.
#
# Graphite is a stubborn Django app that must reside at the DocumentRoot level
# and is not readily moved to a subpath.
#
# The following config allows you to reach the graphite composer at
# http://HOSTNAME/graphite. The graphite will redirect all URLs back at the top
# level, so the remaining locations handle those and pass them back to the
# uwsgi server.
