pm2 startup doesn't work

I setup my nodejs server successfully and I'm using it on Ubuntu 15.04 server, my issue is that I want my node applications to keep running when the server reboots so I tried pm2, forever and crontab but none of them worked for me, after rebooting I need to start the node application manually.

I tried pm2 as follow:

pm2 startup ubuntu
pm2 start appname
pm2 save

The pm2-init.sh file:

#!/bin/bash                                                     
# chkconfig: 2345 98 02                                         
#

exit $RETVAL

That didn't work, so I tried to use crontab as follow: First, I create a script and named it starter.sh

#!/bin/bash
pm2 start /home/bashar/www/node/server.js

Then opened crontab editor:

crontab -e
@reboot /home/bashar/www/node/server.js

Also the above method didn't start my application on the server reboot.

Please advice,

For anyone who is here looking for Windows machines(as I did), pm2 startup works with unix system only.

https://pm2.keymetrics.io/docs/usage/startup/#init-systems-supported

Try this: https://www.npmjs.com/package/pm2-windows-startup

pm2 seems to have a bug during the reboot. After adding pm2 to the automagically starting processes in /etc/init.d, the script works fine under normal processing, but does something weird under a reboot: it wipes the pm2.dump file empty. There are several bug reports like this one, but so far it's still a bug...

The easiest work-around that I've found is as follows:

  1. Edit /etc/init.d/pm2-init.sh, and comment out the line "super $PM2 dump" in the section for stop()
  2. Whenever you modify your pm2 process list, remember to do a manual "pm2 dump"

If anyone has a more permanent solution, please let me know... :)
