<p>Apache is heavier than <a class="reference internal" href="nginx_install.html"><em>Nginx</em></a>. But it&#8217;s also much more famous:</p>
<ul class="simple">
<li>more people will be able to help you on forums;</li>
<li>your hosting will most probably support Apache;</li>
<li>the configuration file syntax is familiar to a lot of people.</li>
</ul>
<p>An Apache setup is still much more robust and secure than an easy installation.</p>
<p>Une installation apache est aussi beaucoup plus solide et sécurisé qu&#8217;une
installation facile. You&#8217;ll benefit from having:</p>
<ul class="simple">
<li>the possiblity to have several projects listening to the port 80;</li>
<li>several Apache module at your disposal (like requests throttling);</li>
<li>Apache robustness in front end: it&#8217;s secure, and there is much less chance
it will crash under heavy load;</li>
<li>your web site processes won&#8217;t run with admin rights, even if
<a class="reference internal" href="options.html#user-and-group-en"><em>&#8211;user</em></a> doesn&#8217;t
work on your OS.</li>
</ul>
<div class="section" id="mod-wsgi">
<h2>Mod_wsgi<a class="headerlink" href="#mod-wsgi" title="Permalink to this headline"></a></h2>
<p>The modern Web Python servers all work the same way, following an norm for
interfacing: WSGI.</p>
<p>This is the most performante solution, and the best to use. But it will require
the setup of the Apache module mod_wsgi. If you don&#8217;t know how to do this, or
if you can&#8217;t do it (E.G: your hosting won&#8217;t let you), you need to go for
the CGI setup.</p>
<p>First, make sure you have mod_wsgi installed and enable by running (as admin):</p>
<div class="highlight-python"><pre>a2enmod wsgi</pre>
</div>
<p>This enable mod_wsgi. It it doesn&#8217;t, install it first (on ubuntu, the package
is libapache2-mod-wsgi).</p>
<p>Then create an Apache configuration file, usually in /etc/apache/sites-available/.
Name it zerobin:</p>
<div class="highlight-python"><pre>&lt;VirtualHost *:80&gt;
ServerName www.yourwebsite.com
WSGIDaemonProcess zerobin user=www-data group=www-data processes=1 threads=5
WSGIScriptAlias / /path/to/zerobin/app.wsgi
&lt;Directory /path/to/zerobin/zerobin/&gt;
WSGIProcessGroup zerobin
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
&lt;/Directory&gt;
&lt;/VirtualHost&gt;</pre>
</div>
<p>Activate the website (as admin):</p>
<div class="highlight-python"><pre>a2ensite zerobin</pre>
</div>
<p>And reload the apache configuration (as admin):</p>
<div class="highlight-python"><pre>service apache2 reload</pre>
</div>
<p>You&#8217;ll note that we refer to a file named app.wsgi. It&#8217;s a Python file
creating the application Apache is going to use to start the Python process:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">os</span><span class="o">,</span> <span class="nn">sys</span>
<span class="c"># make sure the zerobin module is in the PYTHON PATH and importable</span>
<span class="n">ZEROBIN_PARENT_DIR</span> <span class="o">=</span> <span class="n">os</span><span class="o">.</span><span class="n">path</span><span class="o">.</span><span class="n">dirname</span><span class="p">(</span><span class="n">os</span><span class="o">.</span><span class="n">path</span><span class="o">.</span><span class="n">dirname</span><span class="p">(</span><span class="n">__file__</span><span class="p">))</span>
<span class="n">sys</span><span class="o">.</span><span class="n">path</span><span class="o">.</span><span class="n">insert</span><span class="p">(</span><span class="mi">0</span><span class="p">,</span> <span class="n">ZEROBIN_PARENT_DIR</span><span class="p">)</span>
<span class="c"># create the wsgi callable</span>
<span class="kn">from</span> <span class="nn">zerobin.routes</span> <span class="kn">import</span> <span class="n">get_app</span>
<span class="n">settings</span><span class="p">,</span> <span class="n">application</span> <span class="o">=</span> <span class="n">get_app</span><span class="p">(</span><span class="n">compressed_static</span><span class="o">=</span><span class="bp">True</span><span class="p">)</span>
</pre></div>
</div>
<p>You can of course create your own, as the <cite>get_app</cite> function is the only
way to pass settings to 0bin with this setup. You would do this by creating
a configuration file and passing it to the function:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">os</span><span class="o">,</span> <span class="nn">sys</span>
<span class="n">ZEROBIN_PARENT_DIR</span> <span class="o">=</span> <span class="s">&#39;/path/to/zerobin/parent/dir&#39;</span>
<span class="n">sys</span><span class="o">.</span><span class="n">path</span><span class="o">.</span><span class="n">insert</span><span class="p">(</span><span class="mi">0</span><span class="p">,</span> <span class="n">ZEROBIN_PARENT_DIR</span><span class="p">)</span>
<span class="kn">from</span> <span class="nn">zerobin.routes</span> <span class="kn">import</span> <span class="n">get_app</span>
<span class="n">settings</span><span class="p">,</span> <span class="n">application</span> <span class="o">=</span> <span class="n">get_app</span><span class="p">(</span><span class="n">settings_file</span><span class="o">=</span><span class="s">&#39;/path/to/settings.py&#39;</span><span class="p">)</span>
</pre></div>
</div>

<div class="section" id="cgi">

<p>You can also run 0bin using CGI, but infortunaly we didn&#8217;t have time to cover
it yet. Please contact us if you ever get the need to use it.</p>
