微服务架构 CI/CD 实战
点击上方 蓝字 关注我们
概述
现有 Demo，一项目某块业务拆分为如下几个模块
- book-web 前端，采用 Vue MVVM，服务端 Thymeleaf SSR 渲染，友好 SEO MPA。服务端 路由，Spring MVC
- book-gateway 微服务网关，Spring Cloud Gateway
- book-service 接口提供方，Spring Cloud Alibaba Dubbo 服务消费方
- book-server 数据承载方，Spring Cloud Alibaba Dubbo 服务提供方
- book-common 实体，Dubbo 接口 jar
- cloud-common 微服务公共 jar
- common pom
- school-parent 最上级 父工程 pom
本篇内容使用Jenkis实现自动构建。
common 继承关系
在项目根路径下执行，Maven 命令 mvn clean install -pl com.lab:book-common -am -Ptest，截取输出如下

Maven 环境
root@jazz-pc:/opt# mvn -v
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /usr/local/apache-maven-3.6.3
Java version: 11.0.7, vendor: Oracle Corporation, runtime: /usr/local/java/jdk-11.0.7
Default locale: zh_CN, platform encoding: UTF-8
OS name: "linux", version: "5.3.0-51-generic", arch: "amd64", family: "unix"在settings.xml 文件中，添加国内镜像
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>顶级父工程 pom.xml 添加，跳过Maven单元测试 编译和执行
<maven.test.skip>true</maven.test.skip>
<skipTests>true</skipTests>如果有 Maven Nexus，则另外添加设置，install 替换为 deploy
Jenkins相关配置
启动Jenkis
nohup java -jar /usr/local/jenkins/jenkins.war --ajp13Port=-1 --httpPort=8086 >/usr/local/jenkins/jenkins.out 2>&1 &- Jenkins JDK 环境 >=1.8 and <=11 目前最新版本不支持 Java 14
- Jenkins 安装一般会卡住 2 次，则是去国外下载插件数据缓慢的原因，kill -9 进程 ID，ps -ef | grep jenkins 找到进程 ID。
第一次卡住修改 ：
/root/.jenkins/hudson.model.UpdateCenter.xml文件里面链接内容为国内镜像地址 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json 第二次卡住执行替换命令：
cd /root/.jenkins/updates
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.jsonGit or SVN

- Global Tool Configuration 设置好，JDK，Maven，Git
- 新建 Item，Freestyle project，如下
