CentOs 6에서 루트가 아닌 사용자로 Java 서비스를 실행하는 방법

CentOS 6에서 Java 애플리케이션을 서비스로 시작하는 스크립트가 있습니다.

#!/bin/sh
# chkconfig: - 80 20

SERVICE_NAME=cn4server
PATH_TO_JAR=/usr/local/share/myserver/cn4server.jar
PID_PATH_NAME=/usr/local/share/myserver/cn4server-pid
case $1 in
    start)
        echo "Starting $SERVICE_NAME ..."
        if [ ! -f $PID_PATH_NAME ]; then
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is already running ..."
        fi
    ;;
    stop)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stoping ..."
            kill $PID;
            echo "$SERVICE_NAME stopped ..."
            rm $PID_PATH_NAME
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
    restart)
        if [ -f $PID_PATH_NAME ]; then
            PID=$(cat $PID_PATH_NAME);
            echo "$SERVICE_NAME stopping ...";
            kill $PID;
            echo "$SERVICE_NAME stopped ...";
            rm $PID_PATH_NAME
            echo "$SERVICE_NAME starting ..."
            nohup java -jar $PATH_TO_JAR /tmp 2>> /dev/null >> /dev/null &
                        echo $! > $PID_PATH_NAME
            echo "$SERVICE_NAME started ..."
        else
            echo "$SERVICE_NAME is not running ..."
        fi
    ;;
esac 

잘 작동하지만 루트로 실행 중입니다.

다른 사용자를 대신하여 Java 애플리케이션을 실행하도록 스크립트를 변경하려면 어떻게 해야 합니까?
