Supervisor is a client/server system that allows its users to monitor and control a number of processes on UNIX-like operating systems.
It shares some of the same goals of programs like launchd, daemontools, and runit. Unlike some of these programs, it is not meant to be run as a substitute for init as “process id 1”. Instead it is meant to be used to control processes related to a project or a customer, and is meant to start like any other program at boot time.

If you haven't install supervisor, you'll install it first.
# Debian / Ubuntu: $ sudo apt-get install supervisor
Next, we'll configure it. We need to define a process to listen to.
$ sudo vim /etc/supervisor/conf.d/mysocket.conf
Add this to your new conf file, changing file paths and your environment as necessary
[program:mysocket] command=php artisan brainsocket:start directory=/path/to/laravel stdout_logfile=/path/to/laravel/app/storage/logs/mysocket_brainsocket.log redirect_stderr=true
We now have a process called "mysocket" which we can tell Supervisord to start and monitor.
Let's do that:
$ sudo supervisorctl > reread # Tell supervisord to check for new items in /etc/supervisor/conf.d/ > add mysocket # Add this process to Supervisord > start mysocket # May say "already started"
Now the "mysocket" process is on and being monitored. If our queue listener fails, Supervisord will restart the
php artisan brainsocket:start process.
