Allowing user to do sudo pm2 :

First get your npm directory:

npm get prefix

For example, you get

/home/azureuser/.npm-global

Now you add /bin to it:

/home/azureuser/.npm-global/bin

That will be our NPM_BIN_PATH.

Now, login as root

sudo su

Then open / edit the sudoers file:

visudo

Change the following:

Change

Defaults        env_reset

To

Defaults        !env_reset

Then at

Defaults        secure_path="OTHER_SECURE_PATH_ENTRIES_GO_HERE"

Append your NPM_BIN_PATH and A COLON

In our example that will be: /home/azureuser/.npm-global/bin:

So it should look like:

Defaults        secure_path="/home/azureuser/.npm-global/bin:OTHER_SECURE_PATH_ENTRIES_GO_HERE"

CTRL + X then Y then ENTER to save it.
Done. you can now run sudo pm2 as a user.

Allowing root to run pm2 :

Now open / edit your etc/environment file:

sudo nano /etc/environment

At

PATH="..."

It should look like:

PATH="/home/azureuser/.npm-global/bin:OTHER_PATH_ENTRIES_GO_HERE"

CTRL + X then Y then ENTER to save it.
Done. you can now run pm2 as the root.

Concatenated Commands.

NodeJS:
sudo apt-get update && sudo apt-get upgrade -y && curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install -y nodejs && sudo apt-get install -y build-essential

NPM Globals Tweaks:
mkdir ~/.npm-global && npm config set prefix '~/.npm-global' && sudo chown -R $(whoami) $(npm config get prefix)/lib/node_modules; sudo chown -R $(whoami) $(npm config get prefix)/bin; sudo chown -R $(whoami) $(npm config get prefix)/share; printf "\nPATH=$(npm config get prefix)/bin:$PATH\nexport PATH" >> ~/.bashrc && source ~/.bashrc

PM2 w/ Authbinded Port 80:
npm install pm2@latest -g && sudo apt-get install authbind && sudo touch /etc/authbind/byport/80 && sudo chown $(whoami) /etc/authbind/byport/80 && sudo chmod 755 /etc/authbind/byport/80 && authbind --deep pm2 update && printf "\nalias pm2=\'echo -e \"\t Executing Authbinded PM2\" && authbind --deep pm2\'" >> ~/.bashrc && source ~/.bashrc

Authbind Port 443:
sudo touch /etc/authbind/byport/443 && sudo chown $(whoami) /etc/authbind/byport/443 && sudo chmod 755 /etc/authbind/byport/443

A; B    Run A and then B, regardless of success of A
A && B  Run B if A succeeded
A || B  Run B if A failed
A &     Run A in background.

THanks !! it works
