Run script with rc.local: script works, but not at boot

Question

I have a node.js script which need to start at boot and run under the www-data user. During development I always started the script with:

su www-dat         


        

Answer 1

I got my script to work by editing /etc/rc.local then issuing the following 3 commands.

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults

Now the script works at boot.
