1 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。
2 Jenkins+Docker+SpringCloud集群部署流程说明
3 修改所有微服务配置
3.1 修改注册中心的配置
# 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
- 在启动微服务的时候,加入参数
spring.profile.active
来读取对应的配置。
3.2 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
server:
port: 9002 # 微服务的端口号
spring:
application:
name: service-order # 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-order
prefer-ip-address: true
3.3 提交代码到Gitlab中
4 设计Jenkins集群项目的构建参数
4.1 Jenkins安装Extended Choice Parameter插件
4.2 创建流水线项目
4.3 添加参数
4.3.1 项目名称
4.3.2 最后效果
5 把多个项目提交SonarQube进行代码审核

7 完成微服务多服务器远程发布
7.1 前提说明
- 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。
7.2 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 。
7.3 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
vim deployCluster.sh
#! /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"
chmod +x deployCluster.sh
7.4 修改Jenkinsfile文件
//定义git凭证ID
def git_auth = "7d5c4945-2533-41e2-bd47-5dd97eb37f38"
