Answer 1

Ok got answer myself. I check what happens for

whereis pm2
pm2: /opt/nodejs/bin/pm2

then I checked

whereis userdown
userdown: /usr/bin/userdown /usr/bin/X11/userdown /opt/nodejs/bin/userdown

hmm in /usr/bin.... So I did

sudo ln -s /opt/nodejs/bin/pm2 /usr/bin/pm2 

and it works :)

Answer 2

The problem is that you are running NPM as sudo, so you will only be able to access it using:

sudo pm2 start server.js

Install without sudo, you may even install without the -gflag and call it directly from node_modules directory. This may be useful if you do not have root (admin) privileges in the machine you're working on.

npm install pm2
./node_modules/.bin/pm2 start server.js
