Ensure that the WebSocket server is still running.

Hi there,

Do you know how to ensure that the server is always running. Let's say the (physical) server restarts, will the (WebSocket) server restart automatically?

If not, there must be a service that checks if an instance of the server is launched, and if it is not the case, launch one?

I had the idea to run the command to start the server with a service, but I noticed if two commands are executed, two servers starts with two different PID.

It might be a problem knowing that they are listening on the same port. It's possible that the users on the old server instance are disconnected, I don't know.

Thank you,

This would be a job for something like supervisord. Below is a basic config I use for one of my apps:

[supervisord]
nodaemon=true

[program:app_websocket]
command=php /var/www/html/bin/console gos:websocket:server
numprocs=1
autostart=true
autorestart=true
stdout_logfile=/dev/stdout
stdout_logfile_maxbytes=0
stderr_logfile=/dev/stderr
stderr_logfile_maxbytes=0

Thank you very much :-)
