Starting the WebSocket server
Once you have configured your WebSocket apps and Pusher settings, you can start the Laravel WebSocket server by issuing the artisan command:
php artisan websockets:serve
Using a different port
The default port of the Laravel WebSocket server is
6001. You may pass a different port to the command using the
php artisan websockets:serve --port=3030
This will start listening on port
Restricting the listening host
By default, the Laravel WebSocket server will listen on
0.0.0.0 and will allow incoming connections from all networks. If you want to restrict this, you can start the server with a
--host option, followed by an IP.
For example, by using
127.0.0.1, you will only allow WebSocket connections from localhost.
php artisan websockets:serve --host=127.0.0.1
Keeping the socket server running with supervisord
websockets:serve daemon needs to always be running in order to accept connections. This is a prime use case for
supervisor, a task runner on Linux.
First, make sure
supervisor is installed.
# On Debian / Ubuntu apt install supervisor # On Red Hat / CentOS yum install supervisor systemctl enable supervisor
Once installed, add a new process that
supervisor needs to keep running. You place your configurations in the
/etc/supervisor/conf.d (Debian/Ubuntu) or
/etc/supervisord.d (Red Hat/CentOS) directory.
Within that directory, create a new file called
[program:websockets] command=/usr/bin/php /home/laravel-echo/laravel-websockets/artisan websockets:serve numprocs=1 autostart=true autorestart=true user=laravel-echo
Once created, instruct
supervisor to reload its configuration files (without impacting the already running
supervisorctl update supervisorctl start websockets
Your echo server should now be running (you can verify this with
supervisorctl status). If it were to crash,
supervisor will automatically restart it.
Please note that, by default,
supervisor will force a maximum number of open files onto all the processes that it manages. This is configured by the
minfds parameter in
If you want to increase the maximum number of open files, you may do so in
/etc/supervisor/supervisord.conf (Debian/Ubuntu) or
/etc/supervisord.conf (Red Hat/CentOS):
[supervisord] minfds=10240; (min. avail startup file descriptors;default 1024)
After changing this setting, you'll need to restart the supervisor process (which in turn will restart all your processes that it manages).
