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.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;

namespace Glue4Net.SocketServer
{
public class Server:Glue4Net.IAppModule
{
private Socket mListenSocket;

private IList<Socket> mClients = new List<Socket>();

private bool IsAccepting = false;

private void BeginReceive(Socket e)
{
SocketAsyncEventArgs saea = new SocketAsyncEventArgs();
saea.Completed += OnReceiveCompleted;
saea.SetBuffer(new byte[1024], 0, 1024);
saea.UserToken = e;
if (!e.ReceiveAsync(saea))
{
OnReceiveCompleted(this, saea);
}
}

private void SendData(Socket e, byte[] data, int offset, int count)
{
e.Send(data, offset, count, SocketFlags.None);
}

private void OnReceiveCompleted(object sender, SocketAsyncEventArgs e)
{
if (e.SocketError == SocketError.Success && e.BytesTransferred > 0)
{
SendData((Socket)e.UserToken, e.Buffer, 0, e.BytesTransferred);
BeginReceive((Socket)e.UserToken);
}
else
{
mClients.Remove((Socket)e.UserToken);
Log.Error("{0} disposed!", e.RemoteEndPoint);
}

}

private void OnAccept(object state)
{
while (IsAccepting)
{
try
{
Socket socket = mListenSocket.Accept();
Log.Info("{0} connected!", socket.RemoteEndPoint);
mClients.Add(socket);
BeginReceive(socket);
}
catch (Exception e_)
{
Log.Info("Socket Server Accept error {0}",e_.Message);
}
}
}

public void Load()
{
try
{
mListenSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
mListenSocket.Bind(new IPEndPoint(IPAddress.Any, 10024));
mListenSocket.Listen(10);
IsAccepting = true;
System.Threading.ThreadPool.QueueUserWorkItem(OnAccept);
Log.Info("Socket Server Listen @{0}", 10024);
Log.Info("Load Socket Server Success!");
}
catch (Exception e_)
{
Log.Error("Load Socket Server Error {0}", e_.Message);
}
}

public IEventLog Log
{
get;
set;
}

public string Name
{
get { return "Socket Server"; }
}

private void DisposedSocket(Socket e)
{
try
{

if (e != null)
{
mListenSocket.Close();
mListenSocket.Shutdown(SocketShutdown.Both);
}
}
catch
{
}
}

public void UnLoad()
{
try
{
IsAccepting = false;
DisposedSocket(mListenSocket);
foreach (Socket client in mClients)
{
DisposedSocket(client);
}
Log.Info("Unload Socket Server Success!");
}
catch (Exception e_)
{
Log.Error("Unload Socket Server Error {0}", e_.Message);
}
}
}
}

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.

<add name="socketserver"
compiler="true"
path="H:\SocketServer\"
updateWatch="true"
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.
