Multiple Laravel Reverb Instances on a Single Forge Server — Possible?

Yes, you can run multiple Laravel Reverb instances on a single Forge server, but you need to ensure that each instance uses a different port and has its own configuration. By default, Reverb listens on port 8080, so if you have multiple sites, their Reverb instances will conflict unless you change the ports.

Here's how you can set it up:

1. Configure Different Ports for Each Site

   In each site's .env file, set a unique port for Reverb:

   REVERB_PORT=8081   # For staging
   REVERB_PORT=8082   # For production
   

   Make sure these ports are open in your server's firewall.

2. Update Broadcasting Configuration

   In config/broadcasting.php, ensure the reverb connection uses the environment variable:

   'connections' => [
       'reverb' => [
           'driver' => 'reverb',
           'host' => env('REVERB_HOST', '127.0.0.1'),
           'port' => env('REVERB_PORT', 8080),
       ],
   ],
   

3. Update Your Frontend

   When connecting to Reverb from your frontend (e.g., with Laravel Echo), specify the correct port:

   window.Echo = new Echo({
       broadcaster: 'reverb',
       host: window.location.hostname + ':8081' // or ':8082' for production
   });
   

4. Start Reverb for Each Site

   SSH into your server, navigate to each site's directory, and start Reverb with the correct environment:

   php artisan reverb:start
   

   Or, if you're using Supervisor, ensure each site's Supervisor config uses the correct path and environment.

5. Supervisor Example

   Example Supervisor config for staging (/etc/supervisor/conf.d/staging-reverb.conf):

   [program:staging-reverb]
   process_name=%(program_name)s
   command=php /home/forge/staging.yoursite.com/artisan reverb:start
   autostart=true
   autorestart=true
   user=forge
   redirect_stderr=true
   stdout_logfile=/home/forge/staging.yoursite.com/storage/logs/reverb.log
   environment=REVERB_PORT="8081",APP_ENV="staging"
   

   And similarly for production, but with a different port and path.

Summary:
Yes, it's possible to run multiple Reverb instances on a single Forge server. Just ensure each site uses a different port and the correct environment variables. This setup is similar to running multiple queue workers or websockets servers for different sites on the same machine.
