1、进入jenkins ，点击左边"系统管理"–>“系统配置”–>“ssh server”–>点击“新增”

添加详细服务器ssh信息，在点击“高级”按钮

添加服务器密码端口
二。自动部署的配置：

1、新建任务

2、maven项目

3、参数配置

参数：clean install -Dmaven.test.skip=true -e -U

选择之前创建好的服务器

其中有个.sh的脚步，这个要自己配置在目标服务器。
脚步内容例子：

#!/bin/sh
#defined   
APP_NAME="MsgEngine"
APP_PATH="/project/www/VIG_VTapp_market"
#stop application
echo "stop application"
$APP_PATH/service.sh stop

sleep 5
application_pid=`ps -ef|grep $APP_NAME|grep start|grep -v 'grep'|awk   '{print $2}'` 
while [ -n "$application_pid" ]
do 
 kill -9 $application_pid
 sleep 5
 application_pid=`ps -ef|grep $APP_NAME|grep start|grep -v 'grep'|awk   '{print $2}'` 
 echo "scan application pid :" $application_pid  
done

#start application  
echo "start application"
source /etc/profile
$APP_PATH/service.sh start
sleep 10

servcie.sh 的脚步是：

#!/bin/sh

## java env
export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.242.b08-0.el7_7.x86_64
export JRE_HOME=$JAVA_HOME/bin

## service name
## APP_NAME=center

SERVICE_DIR=/project/www/VIG_VTapp_market/
SERVICE_NAME=MsgEngine
JAR_NAME=$SERVICE_NAME.jar
PID=$SERVICE_NAME.pid

cd $SERVICE_DIR

case "$1" in

    start)
        nohup java -Xms1024M -Xmx1024M -Dspring.profiles.active=vtprodnew -jar $JAR_NAME >/dev/null 2>&1 &
        echo $! > $SERVICE_DIR/$PID
        echo $JRE_HOME"/java -Xms1024M -Xmx1024M -Dspring.profiles.active=vtprodnew -jar  "$JAR_NAME" >/dev/null 2>&1" 
        echo "=== start $SERVICE_NAME"
        ;;

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

        sleep 5

        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
