This guide is for making a NodeJS service with git repos. When you commit to the git repos the nodejs service will restart. This guide assumes you have a WHM/CPanel CentOS server, and will be making an account called dev. - Replace (PROJECT) with a git project name. Ex: newagesoldier_website - Replace (SERVICE) with a service name. Ex: newagesite - Replace (FILE) with your nodejs main file name. Ex: app.js - In WHM -> Create new account -> username: dev - In WHM -> Manage Shell Access: Set user dev to "Normal Shell*". (Jailed Shell causes issues with PM2). - Disable shell fork bomb protection in WHM -> Shell Fork Bomb Protection. - SSH in to your server as root. - Install nodejs & NPM: - If GIT is missing (it shouldn't be), install it. Then install PM2 and make it startup on system reboot: npm install -g pm2 pm2 startup --user dev --hp /home/dev - In CPanel, login as user dev. Go to SSH Access -> Manage SSH Keys -> Generate a New Key. - On Windows Client PC(s): Download the Private Key and place it in "%userprofile%/.ssh". - SSH in to the server as user dev and make a new git project: mkdir /home/dev/git/ mkdir /home/dev/git/(PROJECT) mkdir /home/dev/git/(PROJECT).git cd /home/dev/git/(PROJECT).git git init --bare - On your client computer, clone this repo and do a test push using the URL: ssh://dev@(DOMAIN):/home/dev/git/(PROJECT).git - For each new git project you have to start the pm2 process and save (as dev, not root): cd /home/dev/git/(PROJECT) pm2 start (FILE) --name (SERVICE) pm2 save - Make a post-receive hook script to restart the PM2 service on new code commit: nano /home/dev/git/(PROJECT).git/hooks/post-receive - Copy and paste the script below. Fill in the brackets with your project/service names: #!/bin/bash export GIT_WORK_TREE=/home/dev/git/(PROJECT) echo 'post-receive: Triggered.' cd /home/dev/git/(PROJECT) echo 'post-receive: git check out' git --git-dir=/home/dev/git/(PROJECT).git --work-tree=/home/dev/git/ne$ echo 'post-receive: npm install' sudo npm install echo 'post-receive: done. starting app' pm2 stop (SERVICE) pm2 start (FILE) --name (SERVICE) echo 'post-receive: app started.' - Save, close and mark the post-receive file as executable: chmod a+x /home/dev/git/(PROJECT).git/hooks/post-receive - If this is a NodeJS web service, set your NodeJS script's port to something like 3000 and go to: WHM -> Apache Configuration -> Include Editor -> Pre VirtualHost Include -> All Versions - and paste this code in (replace brackets): ServerName (DEV'S_DOMAIN) ProxyPreserveHost On ProxyPass "/" "

  We use passenger for NodeJS is there a reason you want to use PM2 instead?

  I want to install PM2 to upload a node.js API so that I can put a live application and thus be able to reload them without downtime and facilitate the administration tasks of the system
