# set up cgit using uwsgi & nginx on gentoo

i recommend mainly using the root user for this

this is partially copied from the wiki, but just my setup for when i reinstall :)

 1echo "www-servers/uwsgi cgi" >> /etc/portage/package.use/uwsgi

  5# caching is disabled.

  7
  8# Cache time to live
  9# All cache ttl values are in minutes. Negative ttl values indicate that a page
 10# type will never expire, and thus the first time a URL is accessed, the result
 11# will be cached indefinitely, even if the underlying git repository changes.
 12# Conversely, when a ttl value is zero, the cache is disabled for that
 13# particular page type, and the page type is never cached.

for nginx, just make a server and make sure it looks something like this and add some ssl certs
