Installation of PM2 on Ubuntu so it autostarts scripts

pm2_ubuntu.sh

# Requirements:
# Node Installed
# Safe User that is running as node

#1) Install pm2
sudo npm install -g pm2

#2) Set-up PM2 to autostart upon server rebooting
#sudo env PATH=$PATH:/usr/local/bin pm2 startup <platform> -u <safe_user_not_root>
sudo env PATH=$PATH:/usr/local/bin pm2 startup ubuntu -u ubuntu

#If above works then you will see:
#Adding system startup for /etc/init.d/pm2-init.sh ...
#
#  /etc/rc0.d/K20pm2-init.sh -> ../init.d/pm2-init.sh
#  /etc/rc1.d/K20pm2-init.sh -> ../init.d/pm2-init.sh
#   /etc/rc6.d/K20pm2-init.sh -> ../init.d/pm2-init.sh
#   /etc/rc2.d/S20pm2-init.sh -> ../init.d/pm2-init.sh
#   /etc/rc3.d/S20pm2-init.sh -> ../init.d/pm2-init.sh
#   /etc/rc4.d/S20pm2-init.sh -> ../init.d/pm2-init.sh
#   /etc/rc5.d/S20pm2-init.sh -> ../init.d/pm2-init.sh

#3) Make your node process start with PM2 as a service
pm2 start <name of start file(run.js, start.js, etc.)>

#IMPORTANT NOTE:  Pm2 will only restart items that we're already running prior to server restart.

#OPTIONAL: Running Node on Port 80
##If you want to run NodeJS on port 80 you will need to configure your safe user to allow this as only root can run port 80
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep /usr/local/bin/node
