1. 安装jenkins

    cat /etc/yum.repos.d/jenkins.repo

    [jenkins]

    name=Jenkins

    baseurl=http://pkg.jenkins.io/redhat

    gpgcheck=1

    yum calen all && yum makecache

    yum install -y jenkins

    启动:systemctl satrt jenkins && systemctl enable jenkins

    访问ip+8080端口  配置文件:/etc/sysconfig/jenkins

    安装插件时一直提示离线，修改￥JENKINS_HOME/updates/default.json无效

    解决:在hosts文件指定解析:192.168.0.234	www.google.com重新安装插件

2. 配置jenkins

    系统管理-->全局工具配置-->配置settings.xml，JDK，MVN

3.  新建自由风格项目

     参数化构建过程-->选项参数

     git参数    #需要安装git插件

     字符参数

4. 配置构建触发器

5. 测试

    点击test，测试200

    每次修改jenkins，都需要点击test(否则不生效)

case $Status in

	Deploy)

    	echo "Status:$Status"

        path="${WORKSPACE}/bak/${BUILD_NUMBER}"

        if [ -d $path ];then

        	echo "The ${path} is already exists"

        else

        	mkdir -p $path

        fi

        cd ${WORKSPACE}/1.0/${ITEM}

        yarn

		yarn build:dev

        \cp -arf ${WORKSPACE}/1.0/${ITEM}/paylabs-${ITEM} $path

        scp -r ${WORKSPACE}/1.0/${ITEM}/paylabs-${ITEM}/* deploy@192.168.0.229:/data/node/${ITEM}/

        echo "Completing!"

        ;;

     Rollback)

     	echo "Status:$Status"

        echo "Version:$Version"

        scp -rp ${WORKSPACE}/bak/$Version/paylabs-${ITEM}/* deploy@192.168.0.229:/data/node/${ITEM}

        ;;

    *)

    	exit

        ;;

esac

6. 启动脚本

#!/bin/bash

APP_NAME=/data/install/version/pay-web-1.0-RELEASES.jar

#使用说明，用来提示输入参数

usage() {

    echo "Usage: sh robotcenter.sh [start|stop|restart|status]"

    exit 1

}

#检查程序是否在运行

is_exist(){

  pid=`ps -ef|grep $APP_NAME|grep -v grep|awk '{print $2}'`

  #如果不存在返回1，存在返回0

  if [ -z "${pid}" ]; then

   return 1

  else

    return 0

  fi

}

#启动方法

start(){

  is_exist

  if [ $? -eq 0 ]; then

    echo "${APP_NAME} is already running. pid=${pid}"

  else

    nohup java -jar ${APP_NAME}  >robotcenter.out 2>&1 &

  fi

}

#停止方法

stop(){

  is_exist

  if [ $? -eq "0" ]; then

    kill -9 $pid

  else

    echo "${APP_NAME} is not running"

  fi

}

#输出运行状态

status(){

  is_exist

  if [ $? -eq "0" ]; then

    echo "${APP_NAME} is running. Pid is ${pid}"

  else

    echo "${APP_NAME} is NOT running."

  fi

}

#重启

restart(){

  stop

  sleep 5

  start

}

#根据输入参数，选择执行对应方法，不输入则执行使用说明

case "$1" in

  "start")

    start

    ;;

  "stop")

    stop

    ;;

  "status")

    status

    ;;

  "restart")

    restart

    ;;

  *)

    usage

    ;;
