微服务远程发布（至少一分钟前，你根本不知道会有这个吻。一无所有的时候，说明你该拥有的，还没有到来。）

完成微服务多服务器远程发布

1） 配置远程部署服务器

从Jenkins服务器拷贝公钥到docker2远程服务器

ssh-copy-id 192.168.195.182

系统配置->添加远程服务器

 

2） 修改Docker配置信任Harbor私服地址

{

"registry-mirrors": ["https://zydiol88.mirror.aliyuncs.com"],

"insecure-registries": ["192.168.195.183:85"]

}

重启Docker

 

 

3） 添加参数

多选框：部署服务器

 

最终效果：

 

4） 修改Jenkinsfile构建脚本

//git的凭证

def git_auth="1be38991-873b-4a68-8eb6-312347fdc0a4"

//git的URL

def git_url="git@192.168.195.180:kgc_group/tensquare_back.git"

//镜像标签

def tag="latest"

//harbor的url地址

def harbor_url="192.168.195.183:85"

//镜像仓库名

def harbor_name="tensquare"

//harbor的凭证

def harbor_auth="e8b4bf42-2a87-4611-90f7-4b4a75479b5c"

 

node {

    //获取当前选择项目名称

    def selectedProjectNames="${project_name}".split(",")

    //获取当前选择服务器

    def selectedServers="${publish_server}".split(",")

 

 

    stage('pull code') {

        //切换成变量，字符串符号使用双引号

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

    }

 

    stage('check code') {

            for(int i=0;i<selectedProjectNames.length;i++){

                //项目信息  tensquare_eureka_server@10086

                def projectInfo=selectedProjectNames[i]

 

                //当前的项目名称

                def currentProjectName="${projectInfo}".split("@")[0]

 

                //当前的项目端口

                def currentProjectPort="${projectInfo}".split("@")[1]

 

                //定义SonarQubeScanner工具

                def scannerHome = tool 'sonar-scanner'

                            //引用SonarQube系统环境

                            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"

    }

    //打包微服务，制作镜像,上传镜像

    stage('make package images,push images') {

        for(int i=0;i<selectedProjectNames.length;i++){

            //项目信息  tensquare_eureka_server@10086

            def projectInfo=selectedProjectNames[i]

 

            //当前的项目名称

            def currentProjectName="${projectInfo}".split("@")[0]

 

            //当前的项目端口

            def currentProjectPort="${projectInfo}".split("@")[1]

 

            sh  "mvn -f ${currentProjectName} clean package dockerfile:build"

            //定义镜像名称

            def imageName="${currentProjectName}:${tag}"

            //对镜像打标签

            sh "docker tag ${imageName} ${harbor_url}/${harbor_name}/${imageName}"

            //镜像推送到harbor

            withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {

                //登录harbor

                sh "docker login -u ${username} -p ${password} ${harbor_url}"

                //镜像上传

                sh "docker push ${harbor_url}/${harbor_name}/${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.length;j++){

                //获取当前服务器名称

                def currentServerName=selectedServers[j]

                //调用不同服务器模块内容--spring.profiles.active=eureka-server1/eureka-server2

                def activeProfile="--spring.profiles.active="

 

                //根据不同的服务器名称调用不同的服务器配置信息

                if (currentServerName=="master_server"){

                    activeProfile=activeProfile+"eureka-server1"

                }else if (currentServerName=="slave_server"){

                    activeProfile=activeProfile+"eureka-server2"

                }

                //部署应用

                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)])

 

            }

  }

    }

 

}

推送上传gitlab

5） 编写deployCluster.sh部署脚本，放到两台生产服务器中路径：/opt/jenkins_shell/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 tom -p Abcd1234 $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"

 

两台生产服务器集群都启动成功！！！

6） 集群效果

 

后台微服务集群成功！！！

 

Nginx+Zuul集群实现高可用网关

 

 

1）docker2服务器上安装

yum install epel-release -y

yum -y install nginx

 

2）Nginx（已完成）端口也要修改

vi /etc/nginx/nginx.conf

upstream zuulServer{

        server 192.168.153.50:10020 weight=1;

        server 192.168.153.30:10020 weight=1;

    }

location / {

          proxy_pass http://zuulServer/;

        }

 

内容如下：

 

3）重启Nginx： systemctl restart nginx 

4）修改前端Nginx的访问地址

 

再次构建前端工程

 

集群网站成功！！！
