Deploying Flask On Cherokee And Uwsgi

I'm attempting to deploy a flask web app I've developed using cherokee and uwsgi. I got cherokee and uwsgi installed and working (i think uwsgi works), but when I configure the app

Solution 1:

Roberto's suggestion is a good one; it will help diagnose where the error is occurring (i.e. whether it's uWSGI or Cherokee).

I've also recently fought to get uWSGI and Cherokee to work together. I ended up configuring the uWSGI source in Cherokee manually:

• In Cherokee Admin, under the "Sources" tab, add a new source with nickname "uWSGI Source" and socket "/tmp/foo.sock"
  • Change the type to "Local Interpreter"
  • In the interpreter field, enter: /usr/local/bin/uwsgi -x /path/to/uwsgiconfig.xml
• In rule management for the virtual server, click to add a new behaviour rule.
  • Choose a manual configuration of type "Directory" with a path of "/"
  • Set the handler to "uWSGI"
  • Scroll to the bottom and set "Round Robin" for the balancer
  • Add the "uWSGI Source" information source
• Save changes and restart Cherokee

In my uWSGI config file I have something like this (adapted to your example):

<uwsgi>
    <chdir>/srv/mobile-site/app/</chdir>
    <wsgi-file>/srv/mobile-site/app/mobilecms.py</wsgi-file>
    <callable>app</callable>

    <socket>/tmp/foo.sock</socket>
    <chmod-socket>666</chmod-socket>

    <master />
    <processes>1</processes>

    <disable-logging /><!-- Errors are still logged; this just disables request logging which Cherokee takes care of -->

    <vacuum />
    <no-orphans />
</uwsgi>

Note that the Cherokee uWSGI wizard doesn't accept this as a valid configuration file (hence the manual configuration).

Solution 2:

Always try uWSGI deploy without a webserver, before going in production.

uwsgi -x <xmlfile>

It will print a lot of information/errors
