Glue4Net简单部署基于win服务的Socket程序

在写一些服务应用的时候经常把要它部署到windows service中,主要是让系统自动加载相关程序用于后台运行.正常写windows server需要单独写个程序包装和相应的安装类才能完成这些工作.但通过Glue4Net就可以非常简单地把代码或DLL部署到windows server中运行.下面地介绍通过Glue4Net简单地部署一个Socket程序.

安装Glue4net

首要工作是要把Glue4net安装下windows service中,下载http://www.ikende.com/files/file/Glue4net.rar 解压后运行install.bat 这样Glue4net就安装到windows server中.这个时候你要在服务中启动Glue4net,之后windows启动就会自动加载.

实现一个Socket Tcp服务功能

Glue4net可以挂DLL和代码文件,如果功能比较简单那直接写个.cs或.vb文件即可,下面就通过c#写一个简单的Socket Tcp服务.

  1 using System;
  2 using System.Collections.Generic;
  3 using System.Linq;
  4 using System.Net;
  5 using System.Net.Sockets;
  6 using System.Text;
  7 
  8 namespace Glue4Net.SocketServer
  9 {
 10     public class Server:Glue4Net.IAppModule
 11     {
 12         private Socket mListenSocket;
 13 
 14         private IList<Socket> mClients = new List<Socket>();
 15 
 16         private bool IsAccepting = false;
 17 
 18         private void BeginReceive(Socket e)
 19         {
 20             SocketAsyncEventArgs saea = new SocketAsyncEventArgs();
 21             saea.Completed += OnReceiveCompleted;
 22             saea.SetBuffer(new byte[1024], 0, 1024);
 23             saea.UserToken = e;
 24             if (!e.ReceiveAsync(saea))
 25             {
 26                 OnReceiveCompleted(this, saea);
 27             }
 28         }
 29 
 30         private void SendData(Socket e, byte[] data, int offset, int count)
 31         {
 32             e.Send(data, offset, count, SocketFlags.None);
 33         }
 34 
 35         private void OnReceiveCompleted(object sender, SocketAsyncEventArgs e)
 36         {
 37             if (e.SocketError == SocketError.Success && e.BytesTransferred > 0)
 38             {
 39                 SendData((Socket)e.UserToken, e.Buffer, 0, e.BytesTransferred);
 40                 BeginReceive((Socket)e.UserToken);
 41             }
 42             else
 43             {
 44                 mClients.Remove((Socket)e.UserToken);
 45                 Log.Error("{0} disposed!", e.RemoteEndPoint);
 46             }
 47             
 48         }
 49 
 50         private void OnAccept(object state)
 51         {
 52             while (IsAccepting)
 53             {
 54                 try
 55                 {
 56                     Socket socket = mListenSocket.Accept();
 57                     Log.Info("{0} connected!", socket.RemoteEndPoint);
 58                     mClients.Add(socket);
 59                     BeginReceive(socket);
 60                 }
 61                 catch (Exception e_)
 62                 {
 63                     Log.Info("Socket Server Accept error {0}",e_.Message);
 64                 }
 65             }
 66         }
 67 
 68         public void Load()
 69         {
 70             try
 71             {
 72                 mListenSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
 73                 mListenSocket.Bind(new IPEndPoint(IPAddress.Any, 10024));
 74                 mListenSocket.Listen(10);
 75                 IsAccepting = true;
 76                 System.Threading.ThreadPool.QueueUserWorkItem(OnAccept);
 77                 Log.Info("Socket Server Listen @{0}", 10024);
 78                 Log.Info("Load Socket Server Success!");
 79             }
 80             catch (Exception e_)
 81             {
 82                 Log.Error("Load Socket Server Error {0}", e_.Message);
 83             }
 84         }
 85 
 86         public IEventLog Log
 87         {
 88             get;
 89             set;
 90         }
 91 
 92         public string Name
 93         {
 94             get { return "Socket Server"; }
 95         }
 96 
 97         private void DisposedSocket(Socket e)
 98         {
 99             try
100             {
101                 
102                 if (e != null)
103                 {
104                     mListenSocket.Close();
105                     mListenSocket.Shutdown(SocketShutdown.Both);
106                 }
107             }
108             catch
109             {
110             }
111         }
112 
113         public void UnLoad()
114         {
115             try
116             {
117                 IsAccepting = false;
118                 DisposedSocket(mListenSocket);
119                 foreach (Socket client in mClients)
120                 {
121                     DisposedSocket(client);
122                 }
123                 Log.Info("Unload Socket Server Success!");
124             }
125             catch (Exception e_)
126             {
127                 Log.Error("Unload Socket Server Error {0}", e_.Message);
128             }
129         }
130     }
131 }

继承Glue4Net.IAppModule是容器加载运行的规则,需要在Load方法中实现启动运行的工作,然后在UnLoad方法里实现服务关闭的工作.功能完成后把代码保存到任何目录下,这里是保存到H:SocketServer;以上是一个非常简单的Socket TCP服务,把接收的信息回应给发送端.

部署Socket程序

为了保证Glue4Net能加载,必须保让代码目录下存在Glue4Net.Dll这个文件,因为它是模块加载的入口点.把程序加载到Glue4Net是非常简单的事情,只需要在domains.config中添加一个配置即可.

1 <add name="socketserver"
2         compiler="true"
3         path="H:SocketServer"
4             updateWatch="true"
5                watchFilter="*.cs|*.config"/>

添加一个socketserver的应用名,然后目录指向之前存放代码的目录,确认配置信息无误后保存.当文件保后无须对Glue4Net进行重启服务即可加载完成.针对以上编写的代码部署完成后,你只需要telent 127.0.0.1 10024 即可连接到相应的服务中.

总结

通过Glue4Net非常简单就能把程序添加到windows service中运行,而这个部署是基于热加载.当添加或修改某些应用的时候,是完全不会影响其他应用的正常工作.
