Starting the WebSocket server	2

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 --port option.

php artisan websockets:serve --port=3030

This will start listening on port 3030.

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
