应用程序的过渡状态

PM2 is a process manager. PM2 can start, stop, restart and delete processes.

Start a process:

$ pm2 start app.js --name "my-api"
$ pm2 start web.js --name "web-interface"

Now let's say I need to stop the web-interface:

$ pm2 stop web-interface

As you can see the process hasn't disappeared. It's still there but in stopped status.

To restart it just do:

$ pm2 restart web-interface

Now I want to delete the app from the PM2 process list. To do so:

$ pm2 delete web-interface
