I am new to node.js and Raspberry pi, I just followed the tutorial in http://joshondesign.com/2013/10/23/noderpi

now npm -version and node -v shows well.

then I put the server.js file in home/pi/app directory

every time I run sudo node /home/pi/app/server.js or move to the app directory run sudo node server.js

It comes out an error, which is:

sudo : node: command not found?

How to fix that? And is there any method to set the server start automatically every time I boot the Pi?

Try

sudo $(which node) /home/pi/app/server

This way, you are searching the executable file location before running sudo, since your user's PATH is not searchable in a sudo environment.

About autorun, you should search Google for sysvinit or systemd, depending on your operating system. They are able to start daemons as root after boot.

You may want to check this thread: On EC2: sudo node command not found, but node without sudo is ok This should help:

sudo ln -s /usr/local/bin/node /usr/bin/node
sudo ln -s /usr/local/lib/node /usr/lib/node
sudo ln -s /usr/local/bin/npm /usr/bin/npm
sudo ln -s /usr/local/bin/node-waf /usr/bin/node-waf
