To run node.js in system boot - node.js

Question

I have written an API using node.js. I have deployed it in the production environment. Now i ran the program(server.js) using forever.js, its working fine
But i want my node to run when the system boots itself.
I tried by creating a file in \etc\init api.conf with the following content.
start on startup
exec forever start /home/testuser/server.js
But when i reboot my system the above isn't running.Please help me solve this.
Thanks in advance.
EDIT:
Finally i tried this:
# Source function library.
. /lib/lsb/init-functions
NODE_ENV="production"
PORT="2100"
APP_DIR="/home/testuser/API/"
NODE_APP="server.js"
CONFIG_DIR="$APP_DIR"
PID_DIR="$APP_DIR/pid"
PID_FILE="$PID_DIR/server.pid"
LOG_DIR="/home/testuser/APIlogs/"
LOG_FILE="$LOG_DIR/project-debug.log"
NODE_EXEC=$(which node)
pidFile="$PID_DIR/server.pid"
logFile="$LOG_DIR/project-debug.log"
sourceDir=/home/testuser/API
coffeeFile=server.js
scriptId=$sourceDir/$coffeeFile
start() {
echo "Starting $scriptId"
# This is found in the library referenced at the top of the script
start_daemon
# Start our CoffeeScript app through forever
# Notice that we change the PATH because on reboot
# the PATH does not include the path to node.
# Launching forever or coffee with a full path
# does not work unless we set the PATH.
cd $sourceDir
PATH=/usr/local/bin:$PATH
forever start /home/testuser/API/server.js
RETVAL=$?
}
restart() {
echo -n "Restarting $scriptId"
/usr/local/bin/forever restart $scriptId
RETVAL=$?
}
stop() {
echo -n "Shutting down $scriptId"
/usr/local/bin/forever stop $scriptId
RETVAL=$?
}
status() {
echo -n "Status $scriptId"
/usr/local/bin/forever list
RETVAL=$?
}
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status
;;
restart)
restart
;;
*)
echo "Usage: {start|stop|status|restart}"
exit 1
;;
esac
exit $RETVAL
When i tried the following command:
/etc/init.d/API start it works fine. When i reboot the system it says "NO forever process" running.

Answer 1

You should have a look at Upstart. People use it with Node. Forever is good just for testing.

Answer 2

I suggest switching to pm2.
$ npm install pm2 -g
$ pm2 start /home/testuser/server.js
$ pm2 list
PM2 can generate and configure a startup script to keep PM2 and your processes alive at every server restart.
$ pm2 startup ubuntu
To save a process list just do:
$ pm2 save
You check here for more information about setting-up pm2 on a Ubuntu server for production.
