最近做了一些.NET Core的程式，有在Windows下運行的有在CentOS 下運行的，Windows下運行的還好，對Windows下還算比較熟悉了，但CentOS 下每次都是找筆記支持命令

於是今天晚上就乾脆把以.NET Core程式已服務形式啟動的代碼封裝了下，代碼主要是便於安裝。

我們寫好一個程式後然後要已服務啟動每次都是需要輸入命令，對於我這種不記單詞的人來說太痛苦了，

當然windows環境下命令到是很簡單。

廢話不說了先給大家看下效果

CentOS 下的運行效果是這樣的

dotnet ConsoleApp2.dll -i

進行服務的安裝

dotnet ConsoleApp2.dll -u

進行服務的卸載

安裝完成後使用 ps x 進行進程查看是否存在。

Window 下運行效果

安裝完成，我們在到window 服務管理工具去看看

發現已經多了一個服務，說明安裝成功了

然後再來分析代碼

首先CentOS 下讓程式以服務形式啟動我們需要做以下工作

1、寫service文件

2、systemctl 啟動service

service文件內容如下：

[Unit]
Description="服務說明"      
[Service]
Type=simple
GuessMainPID=true
WorkingDirectory=//項目路徑
StandardOutput=journal
StandardError=journal
ExecStart=/usr/bin/dotnet 項目文件dll  //啟動指令
Restart=always

[Install]
WantedBy=multi-user.target

參考：http://www.jinbuguo.com/systemd/systemd.service.html

在使用systemctl 命令使其生效

systemctl enable *.service 使自啟動生效
systemctl start *.service 立即啟動項目服務

那麼結合代碼就好說了

 var servicepath = $"/etc/systemd/system/{serviceName}.service";// 創建服務文件
                    System.IO.File.WriteAllText(servicepath, $"[Unit]{Environment.NewLine}");
                    System.IO.File.AppendAllText(servicepath, $"Description={serviceDescription}{Environment.NewLine}");// 服務描述
                    System.IO.File.AppendAllText(servicepath, $"[Service]{Environment.NewLine}");
                    System.IO.File.AppendAllText(servicepath, $"Type=simple{Environment.NewLine}");//設置進程的啟動類型， 必須設為 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 下安裝服務完成，如果失敗請手動執行以下命令完成安裝:");
                    Console.WriteLine($"systemctl enable {serviceName}.service  //使自啟動生效");
                    Console.WriteLine($"systemctl start {serviceName}.service  //立即啟動項目服務");
                    Console.WriteLine($"systemctl status {serviceName}.service -l //查看服務狀態");

這樣我們就可以安裝並啟動服務了，

那麼windows下麵其實根據簡單，就一個命令

sc create 服務名稱 binpath=啟動文件就可以了

當然需要添加一個ServiceBase的子類，這裡我搞了一個通用的

代碼如下

/// <summary>
    /// Windows 服務
    /// </summary>
    class WinService : ServiceBase
    {
        private static string WinServiceName;
        private static Action<string[]> StartRun;
        public WinService()
        {
            ServiceName = WinServiceName;
        }
        /// <summary>
        /// 啟動服務
        /// </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;
        }
    }

View Code

這裡為什麼是Action<string[]> StartRun; 了就是因為讓服務啟動後執行實際要執行的代碼。

比如demo

class Program
    {
        [Description("這是一個測試服務")]
        [DisplayName("測試服務")]
        static void Main(string[] args)
        {
            DotNet.Install.ServiceInstall.Run("test", args, Run);
        }
        static void Run(string[] args)
        {
            HttpServer httpServer = new HttpServer();
            httpServer.Start();
        }
    }

服務啟動後是執行的Run方法。

WIndows下的安裝代碼那就是
