quick and dirty pm2 example on centos
This will get you started on a centos server with a node process manager with a
basic app in /opt/app/.
If you want to test this out locally, install docker machine, pull this repo, cd into it, then run this:
docker build -t pm2 .
docker run -it pm2 bash
You'll be inside a centos machine with pm2 (a nice process manager) installed. pm2 handles startup from boot, restart, process daemon and logrote.
From the command line, run pm2 to get instructions for running your software.
The command I used to run the app is
pm2 start /opt/app/app.js -i 0 --name appHere are the answers to your questions:
Where are the log files at?
Read the docs to find out where pm2 runs logs
How do the log files get rotated?
pm2 handles logrotate
How does the NodeJS server get started on system boot?
pm2 can be told to auto-start the services, you have to run pm2 as a daemon, but that's in the instructions too.
How is the NodeJS server stopped?
If you ran the command above to start it, you can stop it like
pm2 stop app
How would software updates be handled?
By syadmins, yo! Or, with a git pull and pm2 restart app command.
Easy cheezy!
Is there a better way?
Yep, have your syadmins install the docker daemon on a machine and tell them that you'll be responsible for the images.
