uWSGI |
|
===== |
|
|
|
A newly popular deployment method on servers like `cherokee`_ and `nginx`_ |
|
is uWSGI. To use your WSGI application with uWSGI protocol you will need |
|
a uWSGI server first. uWSGI is both a protocol and an application server; |
|
the application server can serve uWSGI, FastCGI, and HTTP protocols. |
|
|
|
The most popular server is `uwsgi`_, which we will use for this guide. |
|
Make sure to have it installed. |
|
|
|
.. admonition:: Watch Out |
|
|
|
Please make sure in advance that your ``app.run()`` call you might |
|
have in your application file, is inside an ``if __name__ == |
|
'__main__':`` or moved to a separate file. Just make sure it's not |
|
called because this will always start a local WSGI server which we do |
|
not want if we deploy that application to uWSGI. |
|
|
|
Starting your app with uwsgi |
|
---------------------------- |
|
|
|
`uwsgi` is designed to operate on WSGI callables found in python modules. |
|
|
|
Given a flask application in myapp.py, use the following command: |
|
|
|
.. sourcecode:: text |
|
|
|
$ uwsgi -s /tmp/uwsgi.sock --module myapp --callable app |
|
|
|
Or, if you prefer: |
|
|
|
.. sourcecode:: text |
|
|
|
$ uwsgi -s /tmp/uwsgi.sock myapp:app |
|
|
|
Configuring nginx |
|
----------------- |
|
|
|
A basic flask uWSGI configuration for nginx looks like this:: |
|
|
|
location = /yourapplication { rewrite ^ /yourapplication/; } |
|
location /yourapplication { try_files $uri @yourapplication; } |
|
location @yourapplication { |
|
include uwsgi_params; |
|
uwsgi_param SCRIPT_NAME /yourapplication; |
|
uwsgi_modifier1 30; |
|
uwsgi_pass unix:/tmp/uwsgi.sock; |
|
} |
|
|
|
This configuration binds the application to `/yourapplication`. If you want |
|
to have it in the URL root it's a bit simpler because you don't have to tell |
|
it the WSGI `SCRIPT_NAME` or set the uwsgi modifer to make use of it:: |
|
|
|
location / { try_files $uri @yourapplication; } |
|
location @yourapplication { |
|
include uwsgi_params; |
|
uwsgi_pass unix:/tmp/uwsgi.sock; |
|
} |
