Jenkins+Docker+SpringCloud微服務(wù)持續(xù)集成之集群部署

一、集群部署流程說明

環(huán)境配置

#環(huán)境配置
hostnamectl set-hostname web2-server && su
systemctl stop firewalld
systemctl disable firewalld

vim /etc/selinux/config
SELINUX=disabled

vim /etc/resolv.conf
nameserver 114.114.114.114

#安裝依賴包
yum install -y yum-utils device-mapper-persistent-data lvm2

#設(shè)置阿里云鏡像源
cd /etc/yum.repos.d/
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

#安裝 docker-ce 社區(qū)版
yum install -y docker-ce
systemctl start docker
systemctl enable docker

#配置鏡像加速，官方網(wǎng)址可參考：https://help.aliyun.com/document_detail/60750.html
mkdir -p /etc/docker
#直接命令行輸入以下內(nèi)容：

tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://t466r8qg.mirror.aliyuncs.com"]
}
EOF

#把Harbor地址加入到Docker信任列表（harbor倉庫的docker中不需要配）
vim /etc/docker/daemon.json 

{
  "registry-mirrors": ["https://t466r8qg.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.8.20:85"]
}

systemctl daemon-reload                         
systemctl restart docker                        

#網(wǎng)絡(luò)優(yōu)化
vim /etc/sysctl.conf
net.ipv4.ip_forward=1

sysctl -p
systemctl restart network
systemctl restart docker
docker version

二、修改idea中微服務(wù)配置

2.1 注冊中心配置

idea中修改注冊中心eureka的配置，單節(jié)點換成集群

# 集群版
spring:
  application:
    name: EUREKA-HA


---
server:
  port: 10086
spring:
  # 指定profile=eureka-server1
  profiles: eureka-server1
eureka:
  instance:
    # 指定當profile=eureka-server1時，主機名是eureka-server1
    hostname: 192.168.8.17
  client:
    service-url:
      # 將自己注冊到eureka-server1、eureka-server2這個Eureka上面去
      defaultZone: http://192.168.8.17:10086/eureka/,http://192.168.8.16:10086/eureka/

---
server:
  port: 10086
spring:
  profiles: eureka-server2
eureka:
  instance:
    hostname: 192.168.8.16
  client:
    service-url:
      defaultZone: http://192.168.8.17:10086/eureka/,http://192.168.8.16:10086/eureka/

在啟動微服務(wù)的時候，加入?yún)?shù): spring.pro?les.active 來讀取對應(yīng)的配置

2.2 其他微服務(wù)配置

  • 網(wǎng)關(guān)服務(wù)配置
      defaultZone: http://192.168.8.17:10086/eureka/,http://192.168.8.16:10086/eureka/ # Eureka訪問地址
  • 權(quán)限管理配置
      defaultZone: http://192.168.8.17:10086/eureka,http://192.168.8.16:10086/eureka
  • 業(yè)務(wù)模塊配置
      defaultZone: http://192.168.8.17:10086/eureka,http://192.168.8.16:10086/eureka

2.3 提交已修改的配置

三、設(shè)計Jenkins集群項目的構(gòu)建參數(shù)

3.1 安裝Extended Choice Parameter插件

該插件可以支持多選框


3.2 創(chuàng)建流水線項目

3.3 配置項目參數(shù)

逗號必須得是英文，否則出錯

tensquare_eureka_server@10086,tensquare_zuul@10020,tensquare_admin_service@9001,tensquare_gathering@9002

3.4 測試代碼循環(huán)構(gòu)建

  • 循環(huán)測試代碼檢查


  • 循環(huán)打包編譯


     //添加公共子工程
     stage('make install public sub project') {
            sh "mvn -f tensquare_common clean install"
     }
     //編譯打包微服務(wù)，制作鏡像
     stage('make package') {
        for (int i=0;i<selectedProjectNames.length;i++){
            //項目名稱tensquare_eureka_server@10086
            def projectInfo=selectedProjectNames[i]

            //當前項目名稱
            def currentProjectName=projectInfo.split("@")[0]
            //當前端口
            def currentProjectPort=projectInfo.split("@")[1]

            sh "mvn -f ${currentProjectName} clean package dockerfile:build"
            //定義鏡像名稱
            def imageName="${currentProjectName}:${tag}"
            //對鏡像打標簽
            sh "docker tag ${imageName} ${harbor_url}/${harbor_name}/${imageName}"
            //鏡像推送到harbor
            withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {
                //登錄harbor
                sh "docker login -u ${username} -p ${password} ${harbor_url}"
                //鏡像上傳
                sh "docker push ${harbor_url}/${harbor_name}/${imageName}"
                sh "echo 鏡像上傳成功"
            }
        }
            //部署應(yīng)用
            sshPublisher(publishers: [sshPublisherDesc(configName: "master_server", transfers: [sshTransfer(cleanRemote: false, excludes: "", execCommand: "/opt/jenkins_shell/deploy.sh ${harbor_url} ${harbor_name} ${project_name} ${tag} ${port}", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: "[, ]+", remoteDirectory: "", remoteDirectorySDF: false, removePrefix: "", sourceFiles: "")], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
     }
 }

四、完成微服務(wù)多服務(wù)器遠程發(fā)布

4.1 配置遠程部署服務(wù)器

從Jenkins服務(wù)器拷貝公鑰到docker2遠程服務(wù)器

ssh-copy-id 192.168.8.16

4.2 Jenkins中添加遠程服務(wù)器

系統(tǒng)配置中添加遠程服務(wù)器


4.3 修改Docker配置信任Harbor私服地址

vim /etc/docker/daemon.json

{
  "registry-mirrors": ["https://t466r8qg.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.8.20:85"]
}

systemctl restart docker

4.4 項目配置參數(shù)

添加構(gòu)建參數(shù)——》多選框：部署服務(wù)器

4.5 修改Jenkins?le構(gòu)建腳本

//定義gitlab的憑證
 def git_auth="03757112-b3bd-4955-93ef-ad84869f39a9"
 //定義gitlab的URL路徑
 def git_url="git@192.168.8.18:gl/tensquare_back.git"

//鏡像標簽
def tag="latest"
//harbor的url地址
def harbor_url="192.168.8.20:85"
//鏡像倉庫名
def harbor_name="tensquare"
//harbor憑證
def harbor_auth="778a9460-c68d-4ab6-ab7f-f5113ec3a900"

 node {
     //選擇的微服務(wù)項目名稱
     def selectedProjectNames="${project_name}".split(",")
     //獲取當前選擇服務(wù)器
     def selectedServers="${publish_server}".split(",")

     stage('pull code') {
         checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
    }
     stage('check code') {

     //循環(huán)檢查
     for (int i=0;i<selectedProjectNames.length;i++){
         //項目名稱tensquare_eureka_server@10086
         def projectInfo=selectedProjectNames[i]

         //當前項目名稱
         def currentProjectName=projectInfo.split("@")[0]
         //當前端口
         def currentProjectPort=projectInfo.split("@")[1]


          //定義SonarQubeScanner工具
          def scannerHome = tool 'sonar-scanner'
          //引用SonarQube系統(tǒng)環(huán)境
          withSonarQubeEnv('sonarqube') {
          sh """
              cd ${currentProjectName}
              ${scannerHome}/bin/sonar-scanner
             """
          }
     }

     }
     //添加公共子工程
     stage('make install public sub project') {
            sh "mvn -f tensquare_common clean install"
     }
     //編譯打包微服務(wù)，制作鏡像
     stage('make package') {
        for (int i=0;i<selectedProjectNames.length;i++){
            //項目名稱tensquare_eureka_server@10086
            def projectInfo=selectedProjectNames[i]

            //當前項目名稱
            def currentProjectName=projectInfo.split("@")[0]
            //當前端口
            def currentProjectPort=projectInfo.split("@")[1]

            sh "mvn -f ${currentProjectName} clean package dockerfile:build"
            //定義鏡像名稱
            def imageName="${currentProjectName}:${tag}"
            //對鏡像打標簽
            sh "docker tag ${imageName} ${harbor_url}/${harbor_name}/${imageName}"
            //鏡像推送到harbor
            withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {
                //登錄harbor
                sh "docker login -u ${username} -p ${password} ${harbor_url}"
                //鏡像上傳
                sh "docker push ${harbor_url}/${harbor_name}/${imageName}"
                sh "echo 鏡像上傳成功"
            }
            //遍歷所有服務(wù)器，分別部署
            for (int j=0;j<selectedServers.length;j++){
                //獲取當前服務(wù)器名稱
                def currentServerName=selectedServers[j]
                //調(diào)用不同服務(wù)器模塊內(nèi)容--spring.profiles.active=eureka-server1/eureka-server2
                def activeProfile="--spring.profiles.active="

                //根據(jù)不同的服務(wù)器名稱調(diào)用不同的服務(wù)器配置信息
                if (currentServerName=="master_server"){
                    activeProfile=activeProfile+"eureka-server1"
                }else if (currentServerName=="slave_server"){
                    activeProfile=activeProfile+"eureka-server2"
                }
            //部署應(yīng)用
                sshPublisher(publishers: [sshPublisherDesc(configName: "${currentServerName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: "/opt/jenkins_shell/deployCluster.sh ${harbor_url} ${harbor_name} ${currentProjectName} ${tag} ${currentProjectPort} ${activeProfile}", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
            }
        }
    }
}

推送上傳gitlab


4.6 編寫部署腳本

編寫deployCluster.sh部署腳本，放到兩臺生產(chǎn)服務(wù)器中路徑：
/opt/jenkins_shell/deployCluster.sh

4.7 進行構(gòu)建測試

可以看到構(gòu)建成功
