    <p>I'm building an EC2 server using fabric, and want to launch a Twisted server for pyapns. I've tried several different ways of launching the script - simply calling <code>sudo(...)</code>, to creating an <code>init.d</code> script.</p> <p>The command works out to something like this:</p> <pre><code>/usr/local/bin/twistd -r epoll -u www-data -g www-data -l /var/log/apnslistener.log --pidfile=/var/run/apnslistener.pid web --class=pyapns.server.APNSServer --port=7077 -l /var/log/pyapns.log </code></pre> <p>When using fabric, whether calling the line above directly through <code>sudo(...)</code> or using <code>sudo</code> to launch the <code>init.d</code> script, the process won't actually launch successfully. If I log in to the box and launch it directly, the process stays launched.</p> <p>I've gotten it to work through fabric, but I have to launch the init.d script <em>3 times</em> before it sticks. Logging with <code>--spew</code> shows no exception. If I don't run it 3 times, even the .pid file never gets created.</p> <p>I'm lost as to where to start figuring out why this is happening, and the 3x hack works 100% consistently. Any ideas? Thanks!</p> <p><strong>EDIT</strong></p> <p>The output of <code>/var/log/apnslistener.log</code> is the following. Notice how the server is only successfully started the 3rd time.</p> <pre><code>2012-04-16 01:52:08+0000 [-] Log opened. 2012-04-16 01:52:08+0000 [-] twistd 12.0.0 (/usr/bin/python 2.7.2) starting up. 2012-04-16 01:52:08+0000 [-] reactor class: twisted.internet.epollreactor.EPollReactor. 2012-04-16 01:52:09+0000 [-] Log opened. 2012-04-16 01:52:09+0000 [-] twistd 12.0.0 (/usr/bin/python 2.7.2) starting up. 2012-04-16 01:52:09+0000 [-] reactor class: twisted.internet.epollreactor.EPollReactor. 2012-04-16 01:52:10+0000 [-] Log opened. 2012-04-16 01:52:10+0000 [-] twistd 12.0.0 (/usr/bin/python 2.7.2) starting up. 2012-04-16 01:52:10+0000 [-] reactor class: twisted.internet.epollreactor.EPollReactor. 2012-04-16 01:52:10+0000 [-] Site starting on 7077 2012-04-16 01:52:10+0000 [-] Starting factory &lt;twisted.web.server.Site instance at 0x1c6dc20&gt; 2012-04-16 01:52:10+0000 [-] set uid/gid 33/33 2012-04-16 01:52:12+0000 [HTTPChannel,0,127.0.0.1] APNSService __init__ </code></pre>

    1. COIs there any output beyond the log file, i.e. on stderr? I don't know enough about fabric to say where to look for this. When you say "launch it directly" do you mean running the init.d script or invoking the command-line that starts with `/usr/local/bin/twistd`?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
