【Dubbo篇】使用shell脚本维护dubbo服务

脚本示例：

 #!/bin/sh
    ## java env
    export JAVA_HOME=/usr/local/java/jdk1.7.0_72
    export JRE_HOME=$JAVA_HOME/jre
     
    ## service name
    APP_NAME=user
     
    SERVICE_DIR=/home/liuyazhuang/dubboserver/service/$APP_NAME
    SERVICE_NAME=dubbo-service-$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
