6-2 NodeJs项目发布流水线

1. 项目设置

项目配置部分主要是将网站源代码上传到github，然后搭建用户访问的web服务器。再经过Jenkins配置发布代码到web服务器。

1.1 项目代码托管

• 将项目源代码上传到GitHub

1.2 搭建前端Nginx服务

• 安装Nginx服务

  yum -y install nginx 
  service nginx start 
  chkconfig nginx on

• 创建站点目录

  mkdir -p /opt/nginx/myweb

• 配置Nginx

  vim /etc/nginx/conf.d/default.conf
  
  server {
  listen       80 default_server;
  server_name  www.xxxxx.com;
  
  include /etc/nginx/default.d/*.conf;
  
  location / {
      root /opt/nginx/myweb;
      index index.html ;
  }
      
  error_page 404 /404.html;
      location = /40x.html {
  }
  
  error_page 500 502 503 504 /50x.html;
      location = /50x.html {
  }
  
  }
  
  service nginx restart

2. Jenkins配置

2.1 创建项目

• 业务名称: cxy
• 应用名称: cxy-vuedemo-ui
• 应用服务器: VM_7_14_centos
• 站点目录: /opt/nginx/myweb
• 服务端口: 80
• 发布用户: nginx
• 发布分支: master
• 项目地址: http://github.com/xxxx/cxy-webdemo-ui.git

2.2 编写Jenkinsfile

• Jenkinsfile

  #!groovy
  
  
  //Getcode
  String srcUrl = "${env.srcUrl}".trim()
  String branchName = "${env.branchName}".trim()
  
  //Global 
  String workspace = "/opt/jenkins/workspace"
  String targetHosts = "${env.targetHosts}".trim()
  String credentialsId = "24982560-17fc-4589-819b-bc5bea89da77"
  String serviceName = "${env.serviceName}".trim()
  String port = "${env.port}".trim()
  String user = "${env.user}".trim()
  String targetDir = "${env.targetDir}".trim()
    
  
  //Build
  String buildShell = "${env.buildShell}".trim()
  
  //代码检出
  def GetCode(srcUrl,branchName,credentialsId) {
  checkout([$class: 'GitSCM', branches: [[name: "${pathName}"]], 
      doGenerateSubmoduleConfigurations: false, 
      extensions: [], submoduleCfg: [], 
      userRemoteConfigs: [[credentialsId: "${credentialsId}", 
      url: "${srcUrl}"]]])
  }
  
  
  //Pipeline
  
  ansiColor('xterm') {
  node("master"){
      ws("${workspace}") {
          //Getcode
          stage("GetCode"){
              GetCode(srcUrl,branchName,credentialsId)
          }
              
          //Build
          stage("RunBuild"){
              sh """ 
                  ${buildShell} 
                  cd dist && tar zcf ${serviceName}.tar.gz * 
                  mkdir -p /srv/salt/${JOB_NAME}/
                  rm -fr /srv/salt/${JOB_NAME}/*
                  mv ${serviceName}.tar.gz /srv/salt/${JOB_NAME}/
                      
                 """
          }
              
              
          //Deploy
          stage("RunDeploy"){
              sh """ 
                  salt ${targetHosts} cmd.run "rm -fr ${targetDir}/*"
                  salt ${targetHosts} cp.get_file "salt://${JOB_NAME}/${serviceName}.tar.gz ${targetDir}/${serviceName}.tar.gz makedirs=True "
                  salt ${targetHosts} cmd.run "cd ${targetDir} && tar zxf ${serviceName}.tar.gz "
                  salt ${targetHosts} cmd.run "chown ${user}:${user} ${targetDir} -R  "
                  salt ${targetHosts} cmd.run "ls -l "
                  
         
                 """
              
          }
      }              
  }       
  }

3.构建测试
