在CentOS上編寫init.d service script

背景：
之前編寫了一些指令碼，下載了一些開源軟體，想把它們做成系統服務，通過service your_prog_name start這樣的方式來後台運行，並在開機時自動啟動。
在瞭解了daemon命令之後，我發現使用它來編寫這樣的指令碼非常方便，相關樣本如下：

具體配置：
只需要將your_prog_name替換為你真正的指令碼或執行檔案的名稱，將prog_path設定為具體的路徑即可。
# vim /etc/init.d/your_prog_name

#!/bin/bash## Comments to support chkconfig# chkconfig: - 98 02# description: your_prog_name service script## Source function library.. /etc/init.d/functions### Default variablesprog_name="your_prog_name"prog_path="/usr/bin/${prog_name}"pidfile="/var/run/${prog_name}.pid"options="-c your_conf_file"# Check if requirements are met[ -x "${prog_path}" ] || exit 1RETVAL=0start(){  echo -n $"Starting $prog_name: "  daemon $prog_path $options  RETVAL=$?

# chmod +x /etc/init.d/your_prog_name
# chkconfig your_prog_name on

附加service tomcat1 start例子：

#!/bin/sh
#
# chkconfig: 2345 85 21
# description: zimg startup scripts
#
tomcat="/usr/server/tomcat1"
startup="/usr/server/tomcat1/bin/startup.sh"
shutdown="/usr/server/tomcat1/bin/shutdown.sh"
export JAVA_HOME=/usr/local/jdk1.7.0
if [ -f /etc/rc.d/init.d/functions ]; then
        . /etc/rc.d/init.d/functions
fi

start() {
        cd $tomcat
        $startup
        echo "tomcat1 started."
}

stop() {

        cd $tomcat
        $shutdown
        echo "tomcat1 stopped."

}
# See how we were called.
case "$1" in
    start)
        start
        ;;
    stop)
        stop
        ;;
    status)
        ;;
    restart)
        stop
        start
        ;;
    condrestart)
        ;;
    reload)
        ;;
    *)
        echo $"Usage: $0 {start|stop|status|restart|condrestart|reload}"
        ;;
esac
exit $RETVAL
