One option would be to use <a href="https://github.com/benoitc/gunicorn/blob/master/examples/supervisor.conf" rel="noreferrer"><code>Supervisor</code></a> to manage Gunicorn.

Then again i don't see why you can't kill the process via <code>Fabric</code>.
Assuming you let Gunicorn <a href="https://gunicorn-docs.readthedocs.org/en/latest/settings.html?highlight=pid#pidfile" rel="noreferrer">write a pid file</a> you could easily read that file in a <code>Fabric</code> command. 

Something like this should work:

<pre><code>run("kill `cat /path/to/your/file/gunicorn.pid`")
</code></pre>

<code>pkill gunicorn</code> stops all gunicorn daemons. So if you are running multiple instances of gunicorn with different ports, try this shell script.

<pre><code>#!/bin/bash
Port=5000
pid=`ps ax | grep gunicorn | grep $Port | awk '{split($0,a," "); print a[1]}' | head -n 1`
if [ -z "$pid" ]; then
 echo "no gunicorn deamon on port $Port"
else
 kill $pid
 echo "killed gunicorn deamon on port $Port"
fi
</code></pre>

<code>ps ax | grep gunicorn | grep $Port</code> shows the daemons with specific port.

Start:
<pre><code>gunicorn --pid PID_FILE APP:app
</code></pre>
Stop:
<pre><code>kill $(cat PID_FILE)
</code></pre>
The <code>--pid</code> flag of <code>gunicorn</code> requires a single parameter: a file where the process id will be stored. This file is also automatically deleted when the service is stopped.
I have used <code>PID_FILE</code> for simplicity but you should use something like <code>/tmp/MY_APP_PID</code> as file name.
If the PID file exists it means the service is running. If it is not there, the service is not running. To stop the service just kill it as mentioned.
You could also want to include the <code>--daemon</code> flag in order to detach the process from the current shell.

<pre><code>kill -9 `ps -eo pid,command | grep 'gunicorn.*${moduleName:appName}' | grep -v grep | sort | head -1 | awk '{print $1}'`

<code>ps -eo pid,command</code> will only fetch process id, command and args out

<code>grep -v grep</code> to get rid of output like 'grep --color=auto xxx'

<code>sort | head -1</code> to do ascending sort and get first line

<code>awk '{print $1}'</code> to get pid back

One more thing you may need to pay attention to: Where gunicorn is installed and which one you're using?

Ubuntu 16 has gunicorn installed by default, the executable is gunicorn3 and located on /usr/bin/gunicorn3, and if you installed it by pip, it's located on /usr/local/bin/gunicorn. You would need to use <code>which gunicorn</code> and <code>gunicorn -v</code> to find out.

I'm starting gunicorn with the Django command <code>python manage.py run_gunicorn</code>. How can I stop gunicorn properly?

Note: I have a semi-automated server deployment with fabric. Thus using something like <code>ps aux | grep gunicorn</code> to kill the process manually by pid is not an option.

How to stop gunicorn properly

我使用Django命令python manage.py run_gunicorn启动gunicorn。我怎样才能正确地阻止黑角兽？注意:我有一个使用fabric的半自动服务器部署。因此，不能使用像ps aux | grep gunicorn这样的东西通过pid手动终止进程。
