I want deploy a play framework web application from source, and run "play start" to start the application.

I wrote a startup script in /etc/init.d/ which execute "daemon play start" when service start, but the service start command did not return. I guess it's because play start is waiting for me to give him a Ctrl+D. "nohup" can fix it, but with "nohup", I have to run "kill -9 xxx" to stop the application, which is not what I like.

What's the best way to run a play framework application from source as a linux startup service.

Thanks a lot.

Here is simple init.d script, which:

• START: recompiles (if needed) and starts application in background, only if application wasn't already started


• STOP: kills app

Read comments in code carefully.

#!/bin/sh

# /etc/init.d/playapp



# Play project directory is in /var/play/playapp/www, not directly in SDIR

SDIR="/var/play/playapp"



# The following part always gets executed.

echo "PLAYAPP Service"



# The following part carries out specific functions depending on arguments.

case "$1" in

    echo " * Starting PLAYAPP Service"



    if [ -f ${SDIR}/www/target/universal/stage/RUNNING_PID ]

    then        

        PID=$(cat ${SDIR}www/target/universal/stage/RUNNING_PID)



        if ps -p $PID > /dev/null

        then

            echo "   service already running ($PID)"

            exit 1

    cd ${SDIR}/www



    # REPLACE "PROJECT_NAME" with your project name



    if [ ! -f ${SDIR}/www/target/universal/stage/bin/PROJECT_NAME ]

        echo "   recompiling..."



        # REPLACE path to your play command
