修改所有微服务配置
注册中心配置(*)
server:
port: 10086
spring:
application:
name: eureka
# 指定profile=eureka-server1
# profiles: eureka-server1
eureka:
instance:
# 指定当profile=eureka-server1时，主机名是eureka-server1
hostname: 192.168.66.103
client:
service-url:
# 将自己注册到eureka-server1、eureka-server2这个Eureka上面去
defaultZone: http://192.168.66.103:10086/eureka/ #,http://192.168.66.104:10086/eureka/
register-with-eureka: false
fetch-registry: false
#---
#server:
# port: 10086
#spring:
# profiles: eureka-server2
#eureka:
# instance:
# hostname: 192.168.66.104
# client:
# service-url:
# defaultZone: http://192.168.66.103:10086/eureka/,http://192.168.66.104:10086/eureka/
在启动微服务的时候，加入参数 : spring.profiles.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，其他微服务配置都需要加入所有Eureka服务
# Eureka配置 eureka: client: service-url: defaultZone: http://192.168.66.103:10086/eureka,http://192.168.66.104:10086/eureka # Eureka访 问地址 instance: prefer-ip-address: true
把代码提交到Gitlab中
设计Jenkins集群项目的构建参数
1）安装Extended Choice Parameter插件
支持多选框
2）创建流水线项目
3 ）添加参数
字符串参数：分支名称
多选框：项目名称
最后效果：
完成微服务构建镜像，上传私服
//git凭证ID
def git_auth = "f14f1eec-8ba5-44af-a5e1-9714364b256e"
//git的url地址
def git_url = "http://192.168.1.120:88/dalianpai_group/tensquare_back_ha.git"
//镜像的版本号
def tag = "latest"
//Harbor的url地址
def harbor_url = "192.168.1.120:8001"
//镜像库项目名称
def harbor_project = "tensquare"
//Harbor的登录凭证ID
def harbor_auth = "a45cb8c3-49f5-4394-976b-1d5d9825ca5f"
node {
//获取当前选择的项目名称
def selectedProjectNames = "${project_name}".split(",")
//获取当前选择的服务器名称
def selectedServers = "${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') {
for(int i=0;i<selectedProjectNames.length;i++){
//tensquare_eureka_server@10086
def projectInfo = selectedProjectNames[i];
//当前遍历的项目名称
def currentProjectName = "${projectInfo}".split("@")[0]
//当前遍历的项目端口
def currentProjectPort = "${projectInfo}".split("@")[1]
//定义当前Jenkins的SonarQubeScanner工具
def scannerHome = tool 'sonarQube-scanner'
//引用当前JenkinsSonarQube环境
withSonarQubeEnv('sonarQube6.7.4') {
sh """
cd ${currentProjectName}
${scannerHome}/bin/sonar-scanner
"""
}
}
}
stage('编译，安装公共子工程') {
sh "mvn -f tensquare_common clean install"
}
stage('编译，打包微服务工程，上传镜像') {
for(int i=0;i<selectedProjectNames.length;i++){
//tensquare_eureka_server@10086
def projectInfo = selectedProjectNames[i];
//当前遍历的项目名称
def currentProjectName = "${projectInfo}".split("@")[0]
//当前遍历的项目端口
def currentProjectPort = "${projectInfo}".split("@")[1]
sh "mvn -f ${currentProjectName} clean package dockerfile:build"
//定义镜像名称
def imageName = "${currentProjectName}:${tag}"
//对镜像打上标签
sh "docker tag ${imageName} ${harbor_url}/${harbor_project}/${imageName}"
withCredentials([usernamePassword(credentialsId: "${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}/${imageName}"
sh "echo 镜像上传成功"
}
//遍历所有服务器，分别部署
for(int j=0;j<selectedServers.length;j++){
//获取当前遍历的服务器名称
def currentServerName = selectedServers[j]
//加上的参数格式：--spring.profiles.active=eureka-server1/eureka-server2
def activeProfile = "--spring.profiles.active="
//根据不同的服务名称来读取不同的Eureka配置信息
if(currentServerName=="121"){
activeProfile = activeProfile+"eureka-server1"
}else if(currentServerName=="118"){
activeProfile = activeProfile+"eureka-server2"
}
//部署应用
sshPublisher(publishers: [sshPublisherDesc(configName: "${currentServerName}", transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: "/opt/jenkins_shell/deployCluster.sh $harbor_url $harbor_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)])
}
}
}
}
完成微服务多服务器远程发布
1）配置远程部署服务器
拷贝公钥到远程服务器
ssh-copy-id 192.168.1.121
系统配置 ->添加远程服务器
2 ）修改Docker配置信任Harbor私服地址
[root@k8s-master ~]# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://lara9y80.mirror.aliyuncs.com"],
"insecure-registries":[
"192.168.1.120:8001"
]
}
[root@k8s-master ~]#
3）编写deployCluster.sh部署脚本
[root@servcie01 jenkins_shell]# cat 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 eric -p Eric123456 $harbor_url
# 下载镜像
docker pull $imageName
# 启动容器
docker run -di -p $port:$port $imageName $profile
echo "容器启动成功"
[root@servcie01 jenkins_shell]#
集群效果
Nginx+Zuul集群实现高可用网关
3 ）重启Nginx： systemctl restart nginx
4）修改前端Nginx的访问地址
流水线
node {
stage('拉取代码'){
checkout([$class: 'GitSCM', branches: [[name: '*/${branch}']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '979cf306-0c46-4ccd-ab6b-8f4f0c7e03da', url: 'git@192.168.1.120:dalianpai_group/tensquare_font.git']]])
}
stage('打包，部署网站'){
nodejs('121NodeJs') {
sh '''
npm i
npm run build
'''
}
sshPublisher(publishers: [sshPublisherDesc(configName: '121', transfers: [sshTransfer(cleanRemote: false, excludes: '', execCommand: '', execTimeout: 120000, flatten: false, makeEmptyDirs: false, noDefaultExcludes: false, patternSeparator: '[, ]+', remoteDirectory: '/usr/share/nginx/html', remoteDirectorySDF: false, removePrefix: 'dist', sourceFiles: 'dist/**')], usePromotionTimestamp: false, useWorkspaceInPromotion: false, verbose: false)])
}
}
所有服务结果
