4. 创建项目，配置参数
使用上面的tensquare_back项目，并进行参数配置
tensquare_eureka_server
tensquare_zuul
tensquare_admin_service
tensquare_gathering
注册中心
服务网关
认证中心
活动微服务
选择scm方式进行构建
//定义gitlab的凭证
def git_auth="03757112-b3bd-4955-93ef-ad84869f39a9"
//定义gitlab的URL路径
def git_url="[email protected]:gl/tensquare_back.git"
node {
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') {
//定义SonarQubeScanner工具
def scannerHome = tool 'sonar-scanner'
//引用SonarQube系统环境
withSonarQubeEnv('sonarqube') {
sh """
cd ${project_name}
${scannerHome}/bin/sonar-scanner
"""
}
}
}
5. Dockerfile编译、生成镜像
Jenkins上部署docker
yum install -y yum-utils device-mapper-persistent-data lvm2
cd /etc/yum.repos.d/
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl start docker
systemctl enable docker
mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://t466r8qg.mirror.aliyuncs.com"],
"insecure-registries": ["192.168.8.20:85"]
}
EOF
systemctl daemon-reload
systemctl restart docker
vim /etc/sysctl.conf
net.ipv4.ip_forward=1
sysctl -p
systemctl restart network
systemctl restart docker
docker version
5.1 编译打包
修改Jenkinsfile文件，增加common工具的命令，添加编译打包命令
//定义gitlab的凭证
def git_auth="5b02eddd-da09-4cb3-83cc-c5b7a333b1cf"
//定义gitlab的URL路径
def git_url="[email protected]:gl/tensquare_back.git"
node {
stage('pull code') {
//切换成变量，字符串符号使用双引号
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('check code') {
//定义SonarQubeScanner工具
def scannerHome = tool 'sonar-scanner'
//引用SonarQube系统环境
withSonarQubeEnv('sonarqube') {
sh """
cd ${project_name}
${scannerHome}/bin/sonar-scanner
"""
}
}
//添加公共子工程
stage('make package images') {
sh "mvn -f tensquare_common clean install"
}
//编译打包微服务
stage('make package') {
sh "mvn -f ${project_name} clean package"
}
}
构建测试结果
在构建tensquare_zuul服务网关的时候会报错，因为Jenkins服务器中并没有tensquare_paren工程，zuul需要依赖这个工程，需要传递父工程进Jenkins仓库中
cd /root/repo/com/tensquare/
#压缩包拖到目录下，解压缩，删除压缩包
unzip tensquare_parent.zip
rm -rf tensquare_parent.zip
重新构建查看结果
5.2 构建镜像
//添加公共子工程
stage('make package images') {
sh "mvn -f tensquare_common clean install"
}
//编译打包微服务,制作镜像
stage('make package') {
sh "mvn -f ${project_name} clean package dockerfile:build"
}
}
提交代码后构建进行测试
5.3 镜像打标签
修改Jenkinsfile文件，添加打标签代码
//镜像标签
def tag="latest"
//harbor的url地址
def harbor_url="192.168.8.20:85"
//镜像仓库名
def harbor_name="tensquare"
//添加公共子工程
stage('make package images') {
sh "mvn -f tensquare_common clean install"
}
//编译打包微服务,制作镜像
stage('make package') {
sh "mvn -f ${project_name} clean package dockerfile:build"
//定义镜像名称
def imageName="${project_name}:${tag}"
//对镜像打标签
sh "docker tag ${imageName} ${harbor_url}/${harbor_name}/${imageName}"
}
}
构建后查看结果
5.4 镜像上传harbor仓库
Jenkins中添加 harbor 的凭证
复制凭证中的id，jenkinsfile脚本的变量中会用到这个凭证的ID
2c76fc90-8116-44b3-a080-6ea04eaba2e7
使用流水线语法中的片段生成器来生成代码，并把复制到Jenkinsfile脚本中进行更改参数
//镜像推送到harbor
withCredentials([usernamePassword(credentialsId: "${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"
}
}
}
更改提交代码后，构建测试镜像上传
到此，所有微服务的镜像成功上传到harbor仓库中
5.5 拉取镜像和发布
安装 Publish Over SSH 插件，Publish Over SSH 插件可以实现远程发送Shell命令，安装完需要重启 Jenkins
Publish Over SSH
配置远程部署服务器
#拷贝公钥，从Jenkins服务器拷贝到生产服务器
ssh-copy-id 192.168.8.17
Jenkins 系统配置中添加远程服务器
拉到最下面进行配置
修改Jenkinsfile构建脚本生成远程调用模板代码
//部署应用
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)])
}
}
项目配置中添加端口新参数
部署脚本deploy.sh中的内容
#! /bin/sh
#接收外部参数
harbor_url=$1
harbor_project_name=$2
project_name=$3
tag=$4
port=$5
imageName=$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
echo "容器启动成功"
在生产服务器上创建目录，并放入脚本
192.168.8.17
mkdir /opt/jenkins_shell
cd /opt/jenkins_shell/
vim deploy.sh
chmod +x deploy.sh
Jenkinsfile更改提交进行构建测试

yum install -y epel-release
yum -y install nginx
vim /etc/nginx/nginx.conf
#39行修改nginx的端口，默认80，改为9090
server {
listen 9090;
listen [::]:9090;
server_name _;
root /usr/share/nginx/html;
#启动Nginx
systemctl enable nginx
systemctl start nginx
访问：http://192.168.8.17:9090/
2. 安装 NodeJS 插件
Jenkins上安装NodeJS插件
全局配置中配置安装NodeJS
3. 配置nginx服务器
前端流水线项目中添加参数化构建

//Gitlab的凭证
def git_auth="dbb2953a-0dab-46a2-b555-fdb7149c4641"
node {
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: '[email protected]:gl/tensquare_front.git']]])
}
stage('make package,deploy') {
//使用nodejs的npm打包
nodejs('nodejs12'){
sh '''
npm install
npm run build
'''
}
//远程部署
sshPublisher(publishers: [sshPublisherDesc(configName: 'master_server', 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)])

对更改的配置进行代码提交
2. 配置集群项目的构建参数
Jenkins中先安装Extended Choice Parameter插件
创建流水线项目，项目名如下：
tensquare_back_cluster
使用scm流水线方式，配置项目参数
tensquare_eureka_server@10086,tensquare_zuul@10020,tensquare_admin_service@9001,tensquare_gathering@9002
注册中心,服务网关,权限中心,活动微服务
效果如下
3. 循环检查、打包编译制作镜像
Jenkinsfile脚本中添加循环代码检查代码，循环打包编译制作镜像代码
//定义gitlab的凭证
def git_auth="5b02eddd-da09-4cb3-83cc-c5b7a333b1cf"
//定义gitlab的URL路径
def git_url="[email protected]:gl/tensquare_back.git"
//镜像标签
def tag="latest"
//harbor的url地址
def harbor_url="192.168.8.20:85"
//镜像仓库名
def harbor_name="tensquare"
//harbor凭证
def harbor_auth="2fc150d3-a81d-4430-ac5a-d523ed63d20c"
node {
//选择微服务项目名称
def selectedProjectNames="${project_name}".split(",")
stage('pull code') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('check code') {
//循环检查
for(int i=0;i提交代码修改
4. 配置远程部署服务器
从Jenkins服务器拷贝公钥到docker2远程服务器
ssh-copy-id 192.168.8.16
jenkins 系统配置中新增远程服务器192.168.8.16
项目中配置参数，添加构建参数——》多选框：部署服务器
5. 添加循环构建
修改Jenkinsfile脚本，添加循环构建代码
//定义gitlab的凭证
def git_auth="5b02eddd-da09-4cb3-83cc-c5b7a333b1cf"
//定义gitlab的URL路径
def git_url="[email protected]:gl/tensquare_back.git"
//镜像标签
def tag="latest"
//harbor的url地址
def harbor_url="192.168.8.20:85"
//镜像仓库名
def harbor_name="tensquare"
//harbor凭证
def harbor_auth="2fc150d3-a81d-4430-ac5a-d523ed63d20c"
node {
//选择的微服务项目名称
def selectedProjectNames="${project_name}".split(",")
//获取当前选择服务器
def selectedServers="${publish_server}".split(",")
stage('pull code') {
checkout([$class: 'GitSCM', branches: [[name: "*/${branch}"]], extensions: [], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_url}"]]])
}
stage('check code') {
//循环检查
for (int i=0;i提交修改的代码
编写deployCluster.sh部署脚本，放到两台生产服务器中并赋权
mkdir /opt/jenkins_shell
cd /opt/jenkins_shell/
#脚本放进此目录下
chmod +x deployCluster.sh
进行构建测试
构建剩下的服务
6. eureka中查看注册结果
http://192.168.8.17:10086/
http://192.168.8.16:10086/
七、配置反向代理
1. web2-server服务器部署nginx
192.168.8.16
yum install epel-release.noarch -y
yum install -y nginx
2. 修改nginx配置文件
vim /etc/nginx/nginx.conf
#37行添加反向代理服务器池，42行出修改端口号
include /etc/nginx/conf.d/*.conf;
upstream zuulServer{
server 192.168.8.16:10020 weight=1;
server 192.168.8.17:10020 weight=1;
}
server {
listen 85;
listen [::]:85;
server_name _;
root /usr/share/nginx/html;
#49行出添加反向代理指向服务器池
include /etc/nginx/default.d/*.conf;
location / {
proxy_pass http://zuulServer/;
}
nginx -t
systemctl start nginx.service
3. 修改前端Nginx的访问地址
地址改为反向代理的地址（web2-server服务器）+配置的85端口
继续点击推送，到gitlab上查看推送结果
4. 构建前端项目并访问查看结果
