#### 1. 修改`a.sh`脚本内容为自己真实的路径： ####

JAVA_HOME=/usr/java/jdk1.7.0_79
    APP_HOME=/data/hanshow_intergration_shopweb2
    MAIN_CLASS=com.hanshow.plugin.entrance.DataExtractor

修改打印服务名称为安装的服务名

echo "Starting myservicename Service..."

#### 2. 将`a.sh`脚本拷贝到`/etc/init.d`下重命名为`a` ####

`a.sh`内容如下：

#!/bin/bash    
    #
    # chkconfig: 345 80 20    
    # description: start the integration service   
    #    
    # Source function library    
    #. /etc/rc.d/init.d/functions   
    JAVA_HOME=/usr/java/jdk1.7.0_79
    APP_HOME=/data/hanshow_intergration_shopweb2
    MAIN_CLASS=com.hanshow.plugin.entrance.DataExtractor
    APP_PID="$APP_HOME/app-daemon.pid"
    case "$1" in
    start)
        echo "Starting Integration_shopweb2 Service..."    
        if [ -f $APP_PID ] ; then
            echo "Integration_shopweb2 Service has already started. Please delete $APP_PID if otherwise."
        else
            bash -c "cd $APP_HOME && nohup $JAVA_HOME/bin/java -Xms1024M -Xmx2048M -Dfile.encoding=utf-8 -classpath lib/*:. $MAIN_CLASS >/dev/null 2>&1 & echo \$! > $APP_PID"
            echo "Integration_shopweb2 Service started"    
        fi
        ;;
    stop)
        echo "Stopping Integration_shopweb2 Service..."    
        if [ -f $APP_PID ] ; then
            PID=`cat $APP_PID`
            pkill -P $PID
            if kill -9 $PID ; then
                echo "Integration_shopweb2 Service stopped"
            else
                echo "Integration Service could not be stopped"
            fi
            rm -f $APP_PID
        fi
        ;;
    *)
        echo "Usage: $prog {start|stop}"    
        ;;
    esac
    exit 0

#### 3. 权限设置 ####

chmod 777  a

#### 4. 安装服务 ####

chkconfig --add  a

#### 5. 启动服务 ####

service a start

#### 6. 关闭服务 ####

service a stop
