How do I keep a websocket server running, even after I close the SSH terminal?

Question

So, I am using Ratchet with PHP, and have currently uploaded a successful websocket example to my server.

It works after I go to SSH, and then just manually run "php bin/chat-server.php".

What I was wondering is that, in a commercial situation, how do I keep the chat server running?

Thanks.

Answer 1

From the Ratchet Deployment page:

if you are running Ubuntu, fallow these steps:

1. install supervisor like this: Installing Supervisor

2. configure ratchet webserver as a service program like this: Supervisor Process Control | Supervisord Install & Usage

making a conf file in /etc/supervisor/conf.d/.conf and fill the conf exmple code from Ratchet Deployment page:

[program:ratchet]
command                 = bash -c "ulimit -n 10000; exec /usr/bin/php /absolute/path/to/ratchet-server-file.php)"
process_name            = Ratchet
numprocs                = 1
autostart               = true
autorestart             = true
user                    = root
stdout_logfile          = ./logs/info.log
stdout_logfile_maxbytes = 1MB
stderr_logfile          = ./logs/error.log
stderr_logfile_maxbytes = 1MB

3. run the following comands:

   • $ supervisorctl reread
   • $ supervisorctl update
   • and finally check if your service is running: $ supervisorctl

these are all the steps that should be added in Ratched Deployment tutorial.. but this approach may not be the best..
