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.
