算命购物网站建设咖啡的营销推广软文

1.创建Job

• 登录Jenkins,点击新建Item,创建项目
  
• 选择Pipeline，然后点击确定
  
• 接下来主要在Pipeline script中编写脚本

2.签出Git仓库

2.1配置Git账号

• Manage Jenkins->Security->Credentials 在凭据界面，选择全局
  
• 添加凭据，添加Git用户名和密码，ID是等下需要使用的。
  

2.2 编写Git签出脚本

• 点击 Build Now，就会执行刚刚的脚本。并在Jenkin主目录->workspace->项目名称 下签出对应的Git仓库

3.配置何时执行

3.1 手动执行

直接点击 Build Now 按钮，会立马执行。

3.2 间隔执行

• 定时获取Git代码，代码更新则构建 (每5分钟执行一次)
  
• 定时构建，不管代码有没有更新(每5分钟执行一次)
  

3.3 Git有更新主动推送构建

• 生成触发地址
  
• 在Git中配置Web 钩子
  使用上面的地址(JENKINS_URL:替换成地址，TOKEN_NAME：替换为身份证令牌Vue1)，配置到Git的Web钩子中。可以点击测试，看返回结果。
  
• 禁用跨站请求伪造(解决错误：No valid crumb was included in the request)
  Git仓库的Web 钩子界面，点击测试推送，返回的响应信息中，提示：No valid crumb was included in the request。
  在Manage Jenkins -> Script Console中执行

hudson.security.csrf.GlobalCrumbIssuerConfiguration.DISABLE_CSRF_PROTECTION = true

• 安装Build Authorization Token Root 插件(解决错误：Authentication required)
  Git仓库的Web 钩子界面，点击测试推送，返回的响应信息中，提示：Authentication required。
  Manage Jenkins->Plugins 搜索Build Authorization Token Root，并点击安装
• Git仓库添加允许列表
  找到gitea的安装目录gitea\custom\conf，编辑app.ini文件
  

4.编写构建脚本

node {try {stage('SCM') {git branch: 'dev', credentialsId: 'Test', url: 'http://127.0.0.1:3000/Test.git'// 更新子模块bat 'git submodule update --init --recursive'bat 'git submodule update --remote'}stage('BUILD') {bat 'dotnet build'}stage('DEPLOY') {bat 'dotnet publish  Test.csproj -c Release -o D:/publish/Test'}}  catch(Exception e){}
}

5.发送邮件

当构建失败时，发送邮件通知。

5.1 配置邮件信息

• 创建邮箱凭据，步骤参考【配置Git账号】
• 配置邮箱服务器信息 Manage Jenkins->System->Extended E-mail Notification
  
• 编写邮件发送脚本

node {stage('SCM') {emailext (subject: "编译失败: ${env.JOB_NAME} [${env.BUILD_NUMBER}]",body: """<p><b>${env.JOB_NAME} [${env.BUILD_NUMBER}]</b> <span style="color:red;">编译失败</span>.</p><p>详情: <a href="${env.BUILD_URL}console">${env.BUILD_URL}console</a></p><br>""",to: "[e-mail]",mimeType: 'text/html',from: "[e-mail]")}
}

6.发布.NET Core 程序

一般Jenkins与应用站点不在同一台服务器，我们可以通过共享文件夹的方式，再使用命令，复制文件到应用站点服务器。

• 编写powershell脚本文件 copy.ps1

if (!(Test-Path "Y:\")) { 
net use Y: \\192.168.1.100\website /user:administrator 123456
}
Start-Sleep 5
$source = "D:\publish\Test"  
$destination = "Y:\Test"  
$timeThreshold = (Get-Date).AddHours(-1) # 设置时间阈值为一个小时前  # 定义要排除的文件扩展名或名称  
$excludeExtensions = @(".pdb")  
$excludeNames = @("tempfile.txt", "backup.log")  # 使用Get-ChildItem获取文件，并通过管道传递给Where-Object进行筛选  
Get-ChildItem -Path $source -Recurse |   Where-Object {   # 检查文件的最后写入时间是否早于阈值  #$_.LastWriteTime -lt $timeThreshold -and  # 检查文件扩展名是否不在排除列表中  (-not $excludeExtensions.Contains($_.Extension.ToLower())) -and  # 检查文件名是否不在排除列表中  (-not $excludeNames.Contains($_.Name.ToLower()))  } |   ForEach-Object {  # 构造目标路径  $destinationPath = $_.FullName.Replace($source, $destination)  # 如果当前项是文件夹，则创建目标文件夹  if ($_.PSIsContainer) {  New-Item -ItemType Directory -Path $destinationPath -Force | Out-Null  } else {  # 否则，复制文件  Copy-Item -Path $_.FullName -Destination $destinationPath -Force  }  
}

• 编写jenkins脚本

powershell  "D:/publish/Test.ps1"

7.启动/停止应用站点

替换.NET Core程序时，需要先停止IIS之后才能替换。我们可以在IIS中部署另外一个程序，该程序可以用来停止/启动应用程序池和应用站点。当我们需要发布.NET Core程序时，我们可以先停止应用程序和应用站点，发布成功后，在启动应用程序池和应用站点。
以下代码需要安装Microsoft.Web.Administration、System.ServiceProcess.ServiceController类库

    [Route("api/[controller]/[Action]")][ApiController]public class IISController : ControllerBase{public string GetName(){return "IIS";}/// <summary>/// 启动站点/// </summary>/// <param name="siteName"></param>/// <returns></returns>[HttpGet("{siteName}")]public bool StartSite(string siteName){var webManager = new ServerManager();var startSite = webManager.Sites[siteName];if (startSite == null){return false;}if (startSite.State.Equals(ObjectState.Stopped)){startSite.Start();}return true;}/// <summary>/// 停止站点/// </summary>/// <param name="siteName"></param>/// <returns></returns>[HttpGet("{siteName}")]public string StopSite(string siteName){var webManager = new ServerManager();var startSite = webManager.Sites[siteName];if (startSite == null){return "不存在";}if (startSite.State.Equals(ObjectState.Started)){startSite.Stop();}return "成功了";}/// <summary>/// 启动应用池/// </summary>/// <param name="poolName"></param>/// <returns></returns>[HttpGet("{poolName}")]public bool StartPool(string poolName){var webManager = new ServerManager();var applicationPool = webManager.ApplicationPools[poolName];if (applicationPool == null){return false;}if (applicationPool.State.Equals(ObjectState.Stopped)){applicationPool.Start();}return true;}/// <summary>/// 停止应用池/// </summary>/// <param name="poolName"></param>/// <returns></returns>[HttpGet("{poolName}")]public bool StopPool(string poolName){var webManager = new ServerManager();var applicationPool = webManager.ApplicationPools[poolName];if (applicationPool == null){return false;}if (applicationPool.State.Equals(ObjectState.Started)){applicationPool.Stop();}return true;}/// <summary>/// 启动服务/// </summary>/// <param name="serviceName"></param>/// <returns></returns>[HttpGet("{serviceName}")]public IActionResult StartService(string serviceName){try{using (var serviceController = new ServiceController(serviceName)){if (serviceController.Status == ServiceControllerStatus.Stopped || serviceController.Status == ServiceControllerStatus.Paused){serviceController.Start();serviceController.WaitForStatus(ServiceControllerStatus.Running, TimeSpan.FromSeconds(30));}return Ok($"Service {serviceName} started successfully.");}}catch (Exception ex){return StatusCode(500, $"An error occurred while trying to start the service: {ex.Message}");}}/// <summary>/// 启动服务/// </summary>/// <param name="serviceName"></param>/// <returns></returns>[HttpGet("{serviceName}")]public IActionResult StopService(string serviceName){try{using (var serviceController = new ServiceController(serviceName)){if (serviceController.Status == ServiceControllerStatus.Running){serviceController.Stop();serviceController.WaitForStatus(ServiceControllerStatus.Stopped, TimeSpan.FromSeconds(30));}return Ok($"Service {serviceName} stopped successfully.");}}catch (Exception ex){return StatusCode(500, $"An error occurred while trying to stop the service: {ex.Message}");}}}

8.完整Jenkins脚本
