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.
