使用Maven构建Dubbo服务的可运行jar包 支持优雅关机

1.Dubbo项目结构如图

---

2. pom文件配置

#注意：此处只展示打包所需的配置

3.生成可执行jar文件

• 生成jar包，项目右键：Run As –> Maven install

  

• 拷贝jar包及lib运行库到服务器上： dubbo-user-service.jar && lib
  

---

4.创建可运行脚本并配置成服务

• 目录结构（目录及文件名最好统一，便于脚本维护）
  

• 创建shell脚本：vim dubbo-user-service.sh

#!/bin/sh
# chkconfig: 2345 20 80
## 配置jdk路径
export JAVA_HOME=/opt/jdk
export JRE_HOME=$JAVA_HOME/jre

## service name
APP_NAME=dubbo-user-service

SERVICE_DIR=/opt/$APP_NAME
SERVICE_NAME=$APP_NAME
JAR_NAME=$SERVICE_NAME\.jar
PID=$SERVICE_NAME\.pid

cd $SERVICE_DIR

case "$1" in

    start)
        nohup $JRE_HOME/bin/java -Xms256m -Xmx512m -jar $JAR_NAME >/dev/null 2>&1 &
        echo $! > $SERVICE_DIR/$PID
        echo "=== start $SERVICE_NAME"
        ;;

    stop)
        kill `cat $SERVICE_DIR/$PID`
        rm -rf $SERVICE_DIR/$PID
        echo "=== stop $SERVICE_NAME"

        sleep 5
                ##
                ## edu-service-aa.jar
                ## edu-service-aa-bb.jar
        P_ID=`ps -ef | grep -w "$SERVICE_NAME" | grep -v "grep" | awk '{print $2}'`
        if [ "$P_ID" == "" ]; then
            echo "=== $SERVICE_NAME process not exists or stop success"
        else
            echo "=== $SERVICE_NAME process pid is:$P_ID"
            echo "=== begin kill $SERVICE_NAME process, pid is:$P_ID"
            kill -9 $P_ID
        fi
        ;;

    restart)
        $0 stop
        sleep 2
        $0 start
        echo "=== restart $SERVICE_NAME"
        ;;

    *)
        ## restart
        $0 stop
        sleep 2
        $0 start
        ;;

esac
exit 0

• 软链到init.d目录下

# cd /etc/init.d/

# ln -s /opt/dubbo-user-service/dubbo-user-service.sh /etc/init.d/dubbo-user-service

• 设置执行权限

# chmod a+x ./dubbo-user-service

• 注册成服务

# chkconfig --add dubbo-user-service
# chkconfig --list #可查看配置的服务

• 设置开机启动

# chkconfig dubbo-user-service on

• 启动

# service dubbo-user-service start

• 停止

# service dubbo-user-service stop

• 重启

# service dubbo-user-service restart
