Laravel Websocket Won't Connect On Production Using Supervisor On Centos 7

I am new to dealing with something like a supervisor on the CentOS server I ask for help to solve this issue.


I am facing issue with Laravel websockets (beyondco). In localhost, everything works well but in production, I started to install the supervisor package for centos 7 and I follow the steps in the documentation step by step.

After I install the supervisor package am going to directory /etc/supervisord.d and create websockets.conf and vim the file with the following:


websockets.conf (i guess that this file has misconfiguration)

[program:websockets] 
command=/usr/bin/php/home/cpanel_real_user_name/artisan websockets:serve --host 0.0.0.0.0(cpanel-real -ip_address) --port 6001
numprocs=1 autostart=true
autorestart=true
user=root

Then am check the status of the supervisor by running command systemctl status supervisor and the result is

    Loaded: loaded (/usr/lib/systemd/system/supervisord.service; enabled; vendor preset: disabled)
   Active: active (running) since Fri 2021-11-12 20:38:56 EET; 29min ago

   CGroup: /system.slice/supervisord.service
           └─18122 /usr/bin/python /usr/bin/supervisord -c /etc/supervisord.conf

But when am try to run supervisorctl start websockets it returns websockets: ERROR (no such process)

Laravel websockets configuration

    'pusher' => [
        'driver' => 'pusher',
        'key' => env('PUSHER_APP_KEY'),

        'app_id' => env('PUSHER_APP_ID'),

            'scheme' => 'https'
        ],
    ],

resources/js/bootstrap.js

import Echo from 'laravel-echo';

window.Pusher = require('pusher-js');
 
window.Echo = new Echo({
    broadcaster: 'pusher',
    key: process.env.MIX_PUSHER_APP_KEY,
    wsHost: window.location.hostname,
    wsPort: 6001,
    forceTLS: true,
    disableStats: true,
});

Am sorry for the long post but I don't have a background about supervisor and I follow the documentation but am not getting the successful result so I share all info to catch if there is something still missing.

Note I voted to close this question as a typo, bcs that's all it is. But there are other details that would not fit in a comment.

In your websockets.conf, this line has a typo:

command=/usr/bin/php/home/cpanel_real_user_name/artisan websockets:serve --host 0.0.0.0.0(cpanel-real -ip_address) --port 6001

artisan is a PHP file, in the root of your Laravel project. You run it by calling php artisan. So we can see your websockets command is missing a space:

command=/usr/bin/php /home/cpanel_real_user_name/artisan websockets: ...
#                   ^ missing space!

You can see this in the Laravel documentation about supervisord configuration.

I also notice this line:

numprocs=1 autostart=true

Is really 2 parameters on one line. I don't know if supervisor supports that, but why risk it when it is clear 1 parameter per line is expected:

numprocs=1
autostart=true

Lastly, note that supervisor requires you to re-read and update when you change the config (I guess a hard service shutdown/restart should also work):

supervisorctl reread
supervisorctl update
