如何开发并一键发布WindowsService项目(netcore普通项目)
netcore下开发windows服务如果是web项目的话,由于aspnetcore本身是支持的,把默认的host.Run改为host.RunAsService就可以了。
但是普通的netcore的控制台项目我终于找到了如下方式来实现:
1. 打开vs 选择创建一个新的netcore 控制台项目
Nuget添加如下引用
- Microsoft.Extensions.Hosting
- System.ServiceProcess.ServiceController
新建一个ServiceBaseLifetime.cs 并将下面的内容复制进去
public class ServiceBaseLifetime : ServiceBase,IHostLifetime { private readonly taskcompletionsource _delayStart = new taskcompletionsource(); public ServiceBaseLifetime(IApplicationLifetime applicationLifetime) { ApplicationLifetime = applicationLifetime ?? throw new ArgumentNullException(nameof(applicationLifetime)); } private IApplicationLifetime ApplicationLifetime { get; } public Task WaitForStartAsync(CancellationToken cancellationToken) { cancellationToken.Register(() => _delayStart.TrySetCanceled()); ApplicationLifetime.ApplicationStopping.Register(Stop); new Thread(Run).Start(); // Otherwise this would block and prevent IHost.StartAsync from finishing. return _delayStart.Task; } private void Run() { try { Run(this); // This blocks until the service is stopped. _delayStart.TrySetException(new InvalidOperationException("Stopped without starting")); } catch (Exception ex) { _delayStart.TrySetException(ex); } } public Task StopAsync(CancellationToken cancellationToken) { Stop(); return Task.CompletedTask; } // Called by base.Run when the service is ready to start. protected override void OnStart(string[] args) { _delayStart.TrySetResult(null); base.OnStart(args); } // Called by base.Stop. This may be called multiple times by service Stop,ApplicationStopping,and StopAsync. // That‘s OK because StopApplication uses a CancellationTokenSource and prevents any recursion. protected override void OnStop() { ApplicationLifetime.StopApplication(); base.OnStop(); } }
新建一个ServiceBaseLifetimeHostExtensions.cs 并将下面的内容复制进去
public static class ServiceBaseLifetimeHostExtensions { public static IHostBuilder UseServiceBaseLifetime(this IHostBuilder hostBuilder) { return hostBuilder.ConfigureServices((hostContext,services) => services.AddSingleton<IHostLifetime,ServiceBaseLifetime>()); } public static void RunAsService(this IHostBuilder hostBuilder) { hostBuilder.UseServiceBaseLifetime().Build().Run(); } public static Task RunAsServiceAsync(this IHostBuilder hostBuilder) { return hostBuilder.UseServiceBaseLifetime().Build().RunAsync(CancellationToken.None); } }
新建一个服务类 TestService.cs 并写入以下内容(该服务就是每1秒往d:\log.txt写入当前时间)
public class TestService: IHostedService,Idisposable { readonly System.Timers.Timer tmBak = new System.Timers.Timer(); public TestService() { tmBak.Interval = 1000;//1秒执行1次 tmBak.AutoReset = true;//执行1次false,一直执行true tmBak.Enabled = true; tmBak.Elapsed += (sender,eventArgs) => { using (StreamWriter sw = new StreamWriter("D:\\log.txt",true)) { sw.WriteLine($"AntDeploy Windows服务:{DateTime.Now:yyyy-MM-dd HH:mm:ss}"); } }; } public Task StartAsync(CancellationToken cancellationToken) { tmBak.Start(); return Task.CompletedTask; } public Task StopAsync(CancellationToken cancellationToken) { tmBak.Stop(); return Task.CompletedTask; } public void dispose() { this.tmBak.dispose(); } }
编辑 Program.cs 写入如下内容,保证既可以作为控制台打开又可以作为windows服务运行:
class Program { // P/Invoke declarations for Windows. [DllImport("kernel32.dll")] static extern IntPtr GetConsoleWindow(); [DllImport("user32.dll")] static extern bool IsWindowVisible(IntPtr hWnd); public static bool HaveVisibleConsole() { return Runtimeinformation.IsOSPlatform(OSPlatform.Windows) ? IsWindowVisible(GetConsoleWindow()) : Console.WindowHeight > 0; } private static async Task Main(string[] args) { var pathToExe = Process.GetCurrentProcess().MainModule.FileName; var pathToContentRoot = Path.GetDirectoryName(pathToExe); Directory.SetCurrentDirectory(pathToContentRoot); var isService = !(Debugger.IsAttached || args.Contains("--console")); if (HaveVisibleConsole()) isService = false; var builder = new HostBuilder() .ConfigureServices((hostContext,services) => { services.AddHostedService<TestService>(); }); if (isService) { await builder.RunAsServiceAsync(); } else { await builder.runconsoleAsync(); } } }
一键发布到服务器,在工程上点击右键 然后选择 AntDeploy
AntDeploy是我开发的一款开源一键部署vs插件(也是支持脱离vs单独使用的一个开源工具)
开源地址:https://github.com/yuzd/AntDeployAgent
配置AntDeploy
添加一个环境 名字叫 测试 然后 在 测试环境里面添加 windows服务器 这里我做测试就添加就是我本机,注意Host里面是填写格式为:ip:端口号
注意:Token不是windows服务器的密码!!!是安装agent后,agent的配置文件里面配置的Token(你自己自定义配置的)
注意:Port不是你要发布的项目的端口号!!!是安装agent后,agent的配置文件里面配置的端口号(你自己自定义配置的)
点击【Connect Test】按钮进行确认agent可以成功链接,否则会发布失败
如果【Connect Fail】失败 请查看 #10
进入 WindowsService Tab界面
Sdk类型选择 netcore
ServiceName 填写上面我们设置的名称:[TestService]
点击 【Deploy】按钮进行发布
确认服务器无误 点击 【是】开始执行一键部署
如果发布出现错误会出现下图所示:
可以在Log里面查看失败原因是因为我部署agent没有用管路员权限 报权限不足失败 需要用管理员权限运行agent才行
部署成功 如下图:
查看D盘下是否log.txt是否正常每隔1秒写入了当前时间
这里演示的是windows服务上没有这个service所以自动创建了。如果service已存在的情况 Deploy 就会全量覆盖 不会重新创建site的。如果想要覆盖时排除指定文件 可以在 Setting Tab界面的IgnoreList里面增加(支持正则)
