Jenkins+Docker+SpringCloud微服务持续集成（下）
Jenkins+Docker+SpringCloud微服务持续集成（下）
Jenkins+Docker+SpringCloud部署方案优化
● 前面部署方案存在的问题：
○ 一次只能选择一个微服务部署。
○ 只有一条生产部署服务器。
○ 每个微服务只有一个实例，容错率低。
● 优化方案：
○ 在一个Jenkins工程中可以选择多个微服务同时发布。
○ 在一个Jenkins工程中可以选择多台生产服务器同时部署。
○ 每个微服务都是以集群高可用的形式部署。
Jenkins+Docker+SpringCloud集群部署流程说明
修改所有微服务配置
修改注册中心的配置
- application.yaml
# 集群版 spring: application: name: Eureka-HA --- server: port: 10086 spring: # 指定当profile=eureka-server1 profiles: eureka-server1 eureka: instance: # 指定当profile=eureka-server1，主机名是eureka-server1 hostname: 192.168.18.103 client: service-url: defaultZone: http://192.168.18.103:10086/eureka,http://192.168.18.104:10086/eureka --- server: port: 10086 spring: profiles: eureka-server2 eureka: instance: hostname: 192.168.18.104 client: service-url: defaultZone: http://192.168.18.103:10086/eureka,http://192.168.18.104:10086/eureka- 1

- 在启动微服务的时候，加入参数spring.profile.active来读取对应的配置。
其他微服务配置
除了Eureka注册中心以外，其他微服务的配置都需要加入所有Eureka的服务。
商品微服务的配置：
server: port: 9001 # 微服务的端口号 spring: application: name: service-product # 微服务的名称 # 配置 eureka eureka: client: service-url: # Eureka Server的地址 defaultZone: http://192.168.18.103:10086/eureka,http://192.168.18.104:10086/eureka instance: instance-id: service-product prefer-ip-address: true- 1

完成微服务多服务器远程发布
● 远程部署服务器（192.168.18.103和192.168.18.104）已安装Docker，并信任Harbor私有仓库。
● 关闭了防火墙。
● 在Publish over SSH那边增加一台远程部署服务器。
在Jenkins项目中增加一个Extended Choice Parameter参数
- 在Jenkins项目中增加一个Extended Choice Parameter参数的目的是可以选择部署到那个服务器，选择Check
在192.168.18.103和192.168.18.104服务器中创建deployCluster.sh
在远程部署服务器的/usr/local目录下，创建deployCluster.sh文件：
cd /usr/local- 1
vim deployCluster.sh- 1
#! /bin/sh #接收外部参数 harbor_url=$1 harbor_project_name=$2 project_name=$3 tag=$4 port=$5 profile=$6 imageName=$harbor_url/$harbor_project_name/$project_name:$tag echo "$imageName" #查询容器是否存在，存在则删除 containerId=`docker ps -a | grep -w ${project_name}:${tag} | awk '{print $1}'` if [ "$containerId" != "" ] ; then #停掉容器 docker stop $containerId #删除容器 docker rm $containerId echo "成功删除容器" fi #查询镜像是否存在，存在则删除 imageId=`docker images | grep -w $project_name | awk '{print $3}'` if [ "$imageId" != "" ] ; then #删除镜像 docker rmi -f $imageId echo "成功删除镜像" fi # 登录Harbor docker login -u xudaxian -p Xudaxian12345678 $harbor_url # 下载镜像 docker pull $imageName # 启动容器 docker run -di -p $port:$port $imageName $profile echo "容器启动成功"- 1
