<p>uWSGI is a deployment option on servers like <a class="reference external" href="http://nginx.org/">nginx</a>, <a class="reference external" href="http://www.lighttpd.net/">lighttpd</a>, and
<a class="reference external" href="http://www.cherokee-project.com/">cherokee</a>; see <a class="reference internal" href="fastcgi.html#deploying-fastcgi"><em>FastCGI</em></a> and
<a class="reference internal" href="others.html#deploying-other-servers"><em>Other Servers</em></a> for other options. 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.</p>
<p>The most popular uWSGI server is <a class="reference external" href="http://projects.unbit.it/uwsgi/">uwsgi</a>, which we will use for this
guide. Make sure to have it installed to follow along.</p>
<div class="admonition-watch-out admonition ">
<p class="first admonition-title">Watch Out</p>
<p class="last">Please make sure in advance that any <tt class="docutils literal"><span class="pre">app.run()</span></tt> calls you might
have in your application file are inside an <tt class="docutils literal"><span class="pre">if</span> <span class="pre">__name__</span> <span class="pre">==</span>
<span class="pre">'__main__':</span></tt> block 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.</p>

<div class="section" id="starting-your-app-with-uwsgi">
<h2>Starting your app with uwsgi<a class="headerlink" href="#starting-your-app-with-uwsgi" title="Permalink to this headline">¶</a></h2>
<p><cite>uwsgi</cite> is designed to operate on WSGI callables found in python modules.</p>
<p>Given a flask application in myapp.py, use the following command:</p>
<div class="highlight-text"><div class="highlight"><pre>$ uwsgi -s /tmp/uwsgi.sock --module myapp --callable app
</pre></div>
</div>
<p>Or, if you prefer:</p>
<div class="highlight-text"><div class="highlight"><pre>$ uwsgi -s /tmp/uwsgi.sock -w myapp:app
</pre></div>
</div>
</div>
<div class="section" id="configuring-nginx">
<h2>Configuring nginx<a class="headerlink" href="#configuring-nginx" title="Permalink to this headline">¶</a></h2>
<p>A basic flask uWSGI configuration for nginx looks like this:</p>
<div class="highlight-python"><pre>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;
}</pre>
</div>
<p>This configuration binds the application to <cite>/yourapplication</cite>. 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 <cite>SCRIPT_NAME</cite> or set the uwsgi modifier to make use of it:</p>
<div class="highlight-python"><pre>location / { try_files $uri @yourapplication; }
location @yourapplication {
include uwsgi_params;
uwsgi_pass unix:/tmp/uwsgi.sock;
}</pre>
