Jenkins-项目部署到多个服务器节点（三十六）

1. 配置多台服务器ssh连接
   
2. 每台服务器都部署docker
3. Jenkins配置
   
   
   
4. 修改Jenkinsfile配置

// git凭证ID
def git_auth = "44e38a42-3679-442e-a628-400f17fba105"
// git的URL地址
def git_url = "http://192.168.17.129:82/eureka_group/eureka-security-server.git"

//Harbor私服地址

// 镜像库项目名称
def harbor_project = "eureka-security-server"
// harbor的登录凭证ID
def harbor_auth = "9b8fc9bb-eba6-4612-9158-8ede15a30000"
node {
     
    // 获取当前选择的项目名称
    def selectedProjecctNames = "${project_name}".split(",")

    // 获取当前选择的所有服务器
    def selectedServers = "${publish_server}".split(",")

    stage('拉取代码') {
     
        checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
    }

    stage('代码审查') {
     
        // 定义当前Jenkins的sonarqube-scanner工具
        def scannerHome = tool 'sonar-scanner'
        // 引入当前sonarqube的服务器环境
        withSonarQubeEnv('sonarqube') {
     
            for(int i=0; i<selectedProjecctNames.size(); i++) {
     
                // 项目名称
                def projectInfo = selectedProjecctNames[i];
                // 端口号
                def currentProjectName = projectInfo.split("@")[0]
                def currentProjectPort = projectInfo.split("@")[1]

                sh """
                        cd ${
     currentProjectName}
                        ${
     scannerHome}/bin/sonar-scanner
                """
                echo "${currentProjectName}完成代码审查"
            }
        }
    }

    stage('编译，安装微服务工程，上传镜像') {
     
        for(int i=0; i<selectedProjecctNames.size(); i++) {
     
            // 项目名称
            def projectInfo = selectedProjecctNames[i];
            // 端口号
            def currentProjectName = projectInfo.split("@")[0]
            def currentProjectPort = projectInfo.split("@")[1]

            sh "mvn -f ${currentProjectName} clean package dockerfile:build"
            // 定义镜像名称
            def imageName = "${currentProjectName}:${tag}"
            // 对镜像打上标签
            sh "docker tag ${imageName} ${harbor_url}/${harbor_project}/${imageName}"
            // 把镜像推送到harbor
            withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {
     
                // 登录到harbor
                sh "docker login -u ${username} -p ${password} ${harbor_url}"
                // 镜像上传
                sh "docker push ${harbor_url}/${harbor_project}/${imageName}"
                //删除本地镜像
                sh "docker rmi -f ${imageName}"
                sh "docker rmi -f ${harbor_url}/${harbor_project}/${imageName}"
                sh "echo 镜像上传成功"
            }


            // 遍历所有服务器，分别部署
            for(int j=0; j<selectedServers.size(); j++) {
     
                // 获取当前遍历的服务器名称
                def currentServerName = selectedServers[j]
                // 加上的参数格式：--spring.profiles.active=true
                def activeProfile = "--spring.profiles.active="

                // 根据不同的而服务器名称来读取不同的eureka的配置信息
                if(currentServerName=="master_server") {
     
                    activeProfile = activeProfile + "eureka-server1"
                }else if(currentServerName=="cluster-slave3") {
     
                    activeProfile = activeProfile + "eureka-server2"
                }
                // 部署应用

                sshPublisher(publishers: [sshPublisherDesc(configName: "${currentServerName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: "/opt/jenkins_shell/deploy.sh $harbor_url $harbor_project $currentProjectName $tag $currentProjectPort $activeProfile", execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '', remoteDirectorySDF: false, removePrefix: '', sourceFiles: '')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
            }
        }
    }
}

5. 修改application.yml配置

#server:
#  port: 8004
#spring:
#  application:
#    name: eureka-security-server
#  security: #配置SpringSecurity登录用户名和密码
#    user:
#      name: macro
#      password: 123456
#eureka:
#  instance:
#    hostname: localhost
#  client:
#    fetch-registry: false
#    register-with-eureka: false

#集群版
spring:
  application:
    name: eureka-security-server-cluster
  security: #配置SpringSecurity登录用户名和密码
    user:
      name: macro
      password: 123456

server:
  port: 8004
spring:
  # 指定profile=eureka-security-server1
  profiles: eureka-security-server1
eureka:
  # 指定当profile=eureka-security-server1时，主机名是192.168.17.133
  instance:
