PM2 Restart with Server

I ran into this issue, and found a solution that works for me. Let's assume I've created a user named 'node' to run pm2. All of the commands below should be run by the node user, in the node user's home directory (/home/node)

Clear any pm2 dump files, and then start the appropriate services
% pm2 delete all
% pm2 dump
% pm2 start app.js --watch
Save the current config to start on reboot
% pm2 save
% sudo pm2 startup centos -u node
Edit the PM2_HOME path in the pm2-init script to match the home directory of the user:
% sudo vi /etc/init.d/pm2-init.sh
export PM2_HOME="/home/node/.pm2"
I found the issue was, the user was being set appropriately in the pm2-init.sh file, but the PM2_HOME directory was set to /root/.pm2 by default

==UPDATE==

For centos, I was able to replace step 2 above with the following:
% sudo su -c "env PATH=$PATH:/usr/local/bin PM2_HOME=/home/node/.pm2 pm2 startup centos -u node"
