最近做了一些.NET Core的程序,有在Windows下运行的 有在CentOS 下运行的,Windows下运行的还好,对Windows下还算比较熟悉了,但CentOS 下 每次都是找笔记支持命令
于是今天晚上就干脆把以.NET Core程序已服务形式启动的代码封装了下,代码 主要是便于安装。
我们写好一个程序后 然后要已服务启动 每次都是需要输入命令,对于我这种不记单词的人来说太痛苦了,
当然windows环境下命令到是很简单。
废话不说了 先给大家看下效果
CentOS 下的运行效果是这样的
dotnet ConsoleApp2.dll -i
进行服务的安装
dotnet ConsoleApp2.dll -u
进行服务的卸载


安装完成后使用 ps x 进行进程查看 是否存在。
Window 下运行效果

安装完成,我们在到window 服务管理工具去看看


发现已经多了一个服务,说明安装成功了
然后再来分析代码
首先CentOS 下让程序以服务形式启动 我们需要做以下工作
1、写service文件
2、systemctl 启动service
service文件内容如下:
[Unit] Description="服务说明" [Service] Type=simple GuessMainPID=true WorkingDirectory=//项目路径 StandardOutput=journal StandardError=journal ExecStart=/usr/bin/dotnet 项目文件dll //启动指令 Restart=always [Install] WantedBy=multi-user.target
参考:http://www.jinbuguo.com/systemd/systemd.service.html
在使用systemctl 命令使其生效
systemctl enable *.service 使自启动生效
systemctl start *.service 立即启动项目服务
那么结合代码就好说了

var servicepath = $"/etc/systemd/system/{serviceName}.service";// 创建服务文件
System.IO.File.WriteAllText(servicepath, $"[Unit]{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"Description={serviceDescription}{Environment.NewLine}");// 服务描述
System.IO.File.AppendAllText(servicepath, $"[Service]{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"Type=simple{Environment.NewLine}");//设置进程的启动类型, 必须设为 simple, forking, oneshot, dbus, notify, idle 之一。
System.IO.File.AppendAllText(servicepath, $"GuessMainPID=true{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"WorkingDirectory={workingDirectory}{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"StandardOutput=journal{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"StandardError=journal{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"ExecStart=/usr/bin/dotnet {System.IO.Path.GetFileName(filePath)}{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"Restart=always{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"[Install]{Environment.NewLine}");
System.IO.File.AppendAllText(servicepath, $"WantedBy=multi-user.target{Environment.NewLine}");
Console.WriteLine(StartProcess("/usr/bin/systemctl", $"enable {serviceName}.service"));
Console.WriteLine(StartProcess("/usr/bin/systemctl", $"start {serviceName}.service"));
Console.WriteLine($"Unix 下安装服务完成,如果失败请手动执行以下命令完成安装:");
Console.WriteLine($"systemctl enable {serviceName}.service //使自启动生效");
Console.WriteLine($"systemctl start {serviceName}.service //立即启动项目服务");
Console.WriteLine($"systemctl status {serviceName}.service -l //查看服务状态");
这样 我们就可以安装并启动服务了,
那么windows下面 其实根据简单 ,就一个命令
sc create 服务名称 binpath=启动文件 就可以了
当然 需要添加一个ServiceBase的子类,这里我搞了一个通用的
代码如下

/// <summary>
/// Windows 服务
/// </summary>
class WinService : ServiceBase
{
private static string WinServiceName;
private static Action<string[]> StartRun;
public WinService()
{
ServiceName = WinServiceName;
}
/// <summary>
/// 启动服务
/// </summary>
/// <param name="args"></param>
protected override void OnStart(string[] args)
{
StartRun(args);
}
public static void Config(Action<string[]> startRun,string serviceName)
{
WinServiceName = serviceName;
StartRun = startRun;
}
}
这里为什么是Action<string[]> StartRun; 了 就是因为让服务启动后 执行实际要执行的代码。
比如demo

class Program
{
[Description("这是一个测试服务")]
[DisplayName("测试服务")]
static void Main(string[] args)
{
DotNet.Install.ServiceInstall.Run("test", args, Run);
}
static void Run(string[] args)
{
HttpServer httpServer = new HttpServer();
httpServer.Start();
}
}
服务启动后是执行的Run方法。
WIndows下的安装代码那就是

/// <summary>
/// Windows 环境下运行
/// </summary>
/// <param name="filePath">启动文件</param>
/// <param name="serviceName">服务名称</param>
/// <param name="displayName">显示名称</param>
/// <param name="serviceDescription">服务说明</param>
/// <param name="args"></param>
/// <param name="startRun">实际运行方法</param>
/// <returns></returns>
static bool RunWin(string filePath, string serviceName,string displayName, string serviceDescription, string[] args, Action<string[]> startRun)
{
if (args.Length == 1)
{
var workingDirectory = System.IO.Path.GetDirectoryName(filePath);
if (System.IO.File.Exists(System.IO.Path.ChangeExtension(filePath, ".exe")))//判断是否存在exe ,如果存在则启动exe
{
filePath = System.IO.Path.ChangeExtension(filePath, ".exe");//修改后缀名为exe
}
else
{
var dotnetPath = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles), "dotnet", "dotnet.exe");//查找默认软件安装目录下的dotnet.exe
if (System.IO.File.Exists(dotnetPath))
{
filePath = $"\\\"{dotnetPath}\\\" \\\"{filePath}\\\"";
}
else
{
dotnetPath = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ProgramFilesX86), "dotnet", "dotnet.exe");//为了防止有的人只装了x86位的,所以查找x86下的软件安装目录下的dotnet.exe
if (System.IO.File.Exists(dotnetPath))
{
filePath = $"\\\"{dotnetPath}\\\" \\\"{filePath}\\\"";
}
else
{
Console.WriteLine($"系统无法定位DotNet Core的安装目录。");
return true;
}
}
}
if (args[0].Equals("-i", StringComparison.OrdinalIgnoreCase))
{
if (!AdminRestartApp(filePath, args))
{
return true;
}
Console.WriteLine(StartProcess("sc.exe", $"create {serviceName} binpath=\"{filePath}\" start=auto DisplayName=\"{displayName}\""));
Console.WriteLine($"Windows 下安装服务完成,如果失败请手动执行以下命令完成安装:");
Console.WriteLine($"sc create {serviceName} binpath=\"{filePath}\" start=auto DisplayName=\"{displayName}\" //安装服务");
using (var service = Registry.LocalMachine.OpenSubKey($@"SYSTEM\CurrentControlSet\Services\{serviceName}", true))
{
service.SetValue("Description", serviceDescription);
}
return true;
}
else if (args[0].Equals("-u", StringComparison.OrdinalIgnoreCase))
{
if (!AdminRestartApp(filePath, args))
{
return true;
}
Console.WriteLine(StartProcess("sc.exe", $"delete {serviceName}"));
Console.WriteLine($"Windows 下卸载服务完成,如果失败请手动执行以下命令完成卸载:");
Console.WriteLine($"sc delete {serviceName} //卸载服务");
return true;
}
}
WinService.Config(startRun, serviceName);
using (var service = new WinService())
{
System.ServiceProcess.ServiceBase.Run(service);
}
return false;
}
这样我们就完美了
