## 一、部署前端Vue项目 ##

第一步、编写构建脚本xxx-build.sh

port=xxx
    #根据端口号查询对应的pid
    pid=$(netstat -nlp | grep :$port | awk '{print $7}' | awk -F"/" '{ print $1 }');
    
    #杀掉对应的进程，如果pid不存在，则不执行
    if [  -n  "$pid"  ];  then
        kill  -9  $pid;
    fi
    
    #进入工作目录，重启baye-ui
    if [ $? -eq 0 ]; then
    	echo "关闭baye-ui成功"
    #让项目在后台运行
    	nohup npm run test >/dev/null 2>&1 &
    	echo "重启成功"
    else
    	echo "无法终止baye-ui"
    fi

第二步、在jenkins中创建构建项目

第三步、配置项目

**（1）工作空间**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1ODEzNjUz_size_16_color_FFFFFF_t_70 1][]

**（2）源码仓库**

**（3）构建触发事件**

**主要讲述push事件**

**A:配置jenkins**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1ODEzNjUz_size_16_color_FFFFFF_t_70 3][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1ODEzNjUz_size_16_color_FFFFFF_t_70 4][]

**B:配置gitlab**

进入gitlab-->进入项目-->打开左侧setting-->选择Integrations-->添加jenkins中获取的URL和token

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzM1ODEzNjUz_size_16_color_FFFFFF_t_70 5][]

**（4）配置构建shell命令**

#禁止构建后中止衍生进程
    BUILD_ID=DONTKILLME
    cd /workspace/baye-ui
    sh ./baye-ui-run.sh

第四步、立即构建，测试配置

### 二、部署后端Cloud项目 ###

### 2.1  服务中编写Dockerfile文件 ###

#基本形式如下
    FROM anapsix/alpine-java:8_server-jre_unlimited
    
    MAINTAINER xxx@qq.com
    #创建服务工作目录
    RUN mkdir -p /xxx-/bin/xxx/xxx-config
    #指定工作目录
    WORKDIR /xxx-/bin/xxx/xxx-config
    #与端口对应
    EXPOSE 11001
    #添加jar包到工作目录
    ADD ./xxx-config/target/xxx-config.jar ./
    #运行服务
    CMD java -Djava.security.egd=file:/dev/./urandom -Xms50m -Xmx300m -jar xxx-config.jar

### 2.2 项目中编写docker-compose.yml ###

version: '2'
    #定义服务
    services:
      xxx-zookeeper:
        image: zookeeper:3.4.13
        ports:

        links:
          - xxx-eureka

        container_name: xxx-monitor
    
      xxx-daemon:
        links:
          - xxx-eureka
          - xxx-redis
          - xxx-config
        build:
          context: ./
          dockerfile: ./xxx-visual/xxx-daemon/Dockerfile
        restart: always
        ports:
          - 5002:5002
        container_name: xxx-daemon
    
      xxx-codegen:
        links:
          - xxx-eureka
          - xxx-redis

        build:
          context: ./
          dockerfile: ./xxx-visual/xxx-codegen/Dockerfile
        restart: always
        ports:
          - 11007:11007
        container_name: xxx-codegen
    
      xxx-tx-manager:
        links:
          - xxx-eureka
          - xxx-redis
          - xxx-config
        build:
          context: ./
          dockerfile: ./xxx-visual/xxx-tx-manager/Dockerfile
        restart: always
        ports:
          - 11008:11008
          - 9998:9998
        container_name: xxx-tx-manager
    
      xxx-base:
        links:
          - xxx-eureka
          - xxx-redis
          - xxx-gateway
          - xxx-config
        build:
          context: ./
          dockerfile: ./xxx-provider/xxx-base-biz/Dockerfile
        restart: always
        ports:
          - 10001:10001
          - 9998:9998

          context: ./
          dockerfile: ./xxx-provider/xxx-vas-biz/Dockerfile
        restart: always
        ports:
          - 10005:10005
        container_name: xxx-vas

**注意：**

links:实现容器间相互通信（最好更改hosts文件，做端口和域名映射）

build:指定Dockerfile文件所在

ports:宿主机与容器端口映射

container\_name:容器名

### 2.3 编写构建脚本 ###

#进入工作目录
    cd /workspace/xxx
    #安装xxx至本地maven仓库
    mvn clean install -Dmaven.test.skip=true -P test
    
    
    #停止容器
    if [ $? -eq 0 ]; then
    	echo "编译成功，开始停止容器"
    	docker-compose stop
    else
    	echo "无法完成编译"
    	exit
    fi
    
    #删除容器
    if [ $? -eq 0 ]; then
    	echo "开始删除容器"
    	docker-compose rm -f
    else
    	echo "无法停止容器"
    	exit
    fi
    
    #重新创建服务
    if [ $? -eq 0 ]; then
    	echo "编译成功，开始重新创建服务"
    	docker-compose build
    else
    	echo "无法删除容器"
    	exit
    fi
    
    #启动eureka
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-eureka
    else
    	echo "无法创建服务"
    	exit
    fi
    
    #启动config
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-config
    else
    	echo "无法启动eureka"
    	exit
    fi
    
    #启动auth
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-auth
    else
    	echo "无法启动config"
    	exit
    fi
    
    #启动gateway
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-gateway
    else
    	echo "无法启动auth"
    	exit
    fi
    
    #启动upms
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-upms
    else
    	echo "无法启动gateway"
    	exit
    fi
    
    
    #启动codegen
    if [ $? -eq 0 ]; then
    	docker-compose up -d xxx-codegen
    else
    	echo "无法启动upms"
    	exit
    fi
    
    
    #删除无用镜像
    if [ $? -eq 0 ]; then
    docker rmi `docker images | grep  "<none>" | awk '{print $3}'`
    fi

### 2.4 配置jenkins ###

与一种配置方式基本一致

### 2.5  立即构建，测试并追踪构建信息 ###
