如何在Windows XP SP3上安装.NET FRAMEWORK 3.5

2011-11-23T03:24:00Z

最近测试公司内部产品的一个安装包，产品内部加载了.NET FRAMEWORK 3.5 安装包。

本地的环境是 Windows XP SP3，经过测试，安装公司产品没问题没问题，安装过程中能自动加载 .NET FRAMEWORK 3.5，也能顺利安装。

客户环境也是 Windows XP SP3，可是经过测试发觉自动加载 .NET FRAMEWORK 3.5，但是不管如何，就是无法顺利安装完毕，经过若干Google和个人经验判断，尝试了6-7种方案，根据方案不同继续深度挖掘，又尝试了不少弯路，最终找到一个99.99999999999999999999999999999%【话不能太满】有效的方法，希望能帮助那些寻找此方法的人提供最佳路径和选择方案，这个方法是：

第一步，检测对方机器是否是 Ghost，如果是，修改机器名，然后重启，否则，忽律此条；

第二步，点击此处下载清除.NET Framework 工具，运行工具，删除 .NET Framework 相关文件和注册表，当然足够强的话，也可以手动去除，呵呵，不过我个人建议使用此工具。

第三步，重启电脑，安装 .NET Framework，肯定成功！

另外预留一个问题给童鞋们：

我们使用 InstallShield 制作安装工具时，桌面生成的快捷方式的图标出不来，但是在安装目录下的快捷方式有图标，这是怎么回事？谢谢。

EF 4.1 Code First Walkthrough

2011-11-09T00:19:00Z

This post will provide an introduction to Code First development and how it can be used with the new DbContext API surface. Code First allows you to define your model using C# or VB.Net classes, optionally additional configuration can be performed using attributes on your classes and properties or by using a Fluent API. Your model can be used to generate a database schema or to map to an existing database.

当你错过了1111年11月11日11点11分11秒11毫秒11微秒11纳秒11皮秒11飞秒11阿秒11渺秒11...

当2012.12.21不是真实以及你还可以活到100年后(2111年11月11日11点11分11秒11毫秒11微秒11纳秒11皮秒11飞秒11阿秒11渺秒11...）

当然如果你觉得你可以活到11111年11月11日11点11分11秒11毫秒11微秒11纳秒11皮秒11飞秒11阿秒11渺秒11...

那么你不必关注2011年11月11日11点11分11秒11毫秒11微秒11纳秒11皮秒11飞秒11阿秒11渺秒11...

如果上述条件你都不具备，那么我们就好好的关注 2011年11月11日11点11分11秒11毫秒11微秒11纳秒11皮秒11飞秒11阿秒11渺秒11...

提前祝“光棍门”光棍节快乐！

How to implement Tags in your web project.

2010-10-25T05:26:00Z

Please click here to download the source code if you want.

========================================================================
ASP.NET APPLICATION : Tags Project Overview
========================================================================

/////////////////////////////////////////////////////////////////////////////
Use:

The project illustrates how to impliment tags.

/////////////////////////////////////////////////////////////////////////////
Create Database:

Setp1. Create a Database in SQL Server 2008 and name it as OceanCMS.

Setp2. Create data table with this SQL Script.

USE [OceanCMS]
GO
/****** Object: Table [dbo].[cms_Tags] ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[cms_Tags](
[TagID] [uniqueidentifier] NOT NULL,
[TagName] [nvarchar](50) NOT NULL,
[CreateDate] [datetime] NOT NULL,
CONSTRAINT [PK_cms_Tags] PRIMARY KEY CLUSTERED
(
[TagID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
/****** Object: Table [dbo].[cms_Articles] ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[cms_Articles](
[ArticleID] [uniqueidentifier] NOT NULL,
[Title] [nvarchar](100) NOT NULL,
[Details] [nvarchar](max) NOT NULL,
[LastModifyDate] [datetime] NOT NULL,
[CreateDate] [datetime] NOT NULL,
CONSTRAINT [PK_cms_Articles] PRIMARY KEY CLUSTERED
(
[ArticleID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
/****** Object: Table [dbo].[cms_ArticleMappingTags]******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[cms_ArticleMappingTags](
[ArticleID] [uniqueidentifier] NOT NULL,
[TagID] [uniqueidentifier] NOT NULL,
[CreateDate] [datetime] NOT NULL,
CONSTRAINT [PK_cms_ArticlesInTags] PRIMARY KEY CLUSTERED
(
[ArticleID] ASC,
[TagID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF,
ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
/****** Object: Default [DF_cms_ArticlesInTags_CreateDate]******/
ALTER TABLE [dbo].[cms_ArticleMappingTags] ADD CONSTRAINT
[DF_cms_ArticlesInTags_CreateDate] DEFAULT (getdate()) FOR [CreateDate]
GO
/****** Object: Default [DF_cms_Articles_ArticleID]******/
ALTER TABLE [dbo].[cms_Articles] ADD CONSTRAINT [DF_cms_Articles_ArticleID]
DEFAULT (newid()) FOR [ArticleID]
GO
/****** Object: Default [DF_cms_Articles_LastModifyDate]******/
ALTER TABLE [dbo].[cms_Articles] ADD CONSTRAINT [DF_cms_Articles_LastModifyDate]
DEFAULT (getdate()) FOR [LastModifyDate]
GO
/****** Object: Default [DF_cms_Articles_CreateDate]******/
ALTER TABLE [dbo].[cms_Articles] ADD CONSTRAINT [DF_cms_Articles_CreateDate]
DEFAULT (getdate()) FOR [CreateDate]
GO
/****** Object: Default [DF_cms_Tags_TagID]******/
ALTER TABLE [dbo].[cms_Tags] ADD CONSTRAINT [DF_cms_Tags_TagID]
DEFAULT (newid()) FOR [TagID]
GO
/****** Object: Default [DF_cms_Tags_CreateDate]******/
ALTER TABLE [dbo].[cms_Tags] ADD CONSTRAINT [DF_cms_Tags_CreateDate]
DEFAULT (getdate()) FOR [CreateDate]
GO

Code Logical:

Step1. Create a C# ASP.NET Web Application in Visual Studio 2010 and name it
as OceanCMS.

Step2. Add ADO.NET Entity Data Model and name it as OceanCMS.edmx.

Setp3. Use Microsoft Visual Studio Wizard to generate the code for OceanCMS.edmx
from database.

反电话推销SEO联合申明[我不是故意想放首页，我只是想借助博客园的力量来关注这样的一个实际的事件]

2010-08-30T18:58:00Z

各位博客园的网友，大家好，这是一篇非技术的灌水贴！

最近总是接到百度，赶集，58同城等骚扰电话！都是要你去做竞价排名或放首页的类似的东西！我觉得这个不是一个很正常的行为！

如何防止类似的骚扰？能否组织一些有效的力量来反对这样的骚扰呢？

大并发处理解决方案(转)

2010-08-10T16:36:00Z

1：html静态化

2：图片服务器分离

3：数据库集群

4：缓存

5：负载均衡

大型高并发高负载网站的系统架构
我在Cernet做过拨号接入平台的搭建，而后在Yahoo3721负载搜索引擎前端平台开发，又在猫扑处理过大型社区猫扑大杂烩的架构升级等工作，同时自己接触和开发过不少大中型网站的模块，因此在大型网站应对高负载和并发的解决方案上有一些积累和经验，可以和大家一起探讨一下。

一个小型的网站，比如个人网站，可以使用最简单的html静态页面就实现了，配合一些图片达到美化效果，所有的页面均存放在一个目录下，这样的网站对系统架构、性能的要求都很简单，随着互联网业务的不断丰富，网站相关的技术经过这些年的发展，已经细分到很细的方方面面，尤其对于大型网站来说，所采用的技术更是涉及面非常广，从硬件到软件、编程语言、数据库、WebServer、防火墙等各个领域都有了很高的要求，已经不是原来简单的html静态网站所能比拟的。

大型网站，比如门户网站。在面对大量用户访问、高并发请求方面，基本的解决方案集中在这样几个环节：使用高性能的服务器、高性能的数据库、高效率的编程语言、还有高性能的Web容器。但是除了这几个方面，还没法根本解决大型网站面临的高负载和高并发问题。

上面提供的几个解决思路在一定程度上也意味着更大的投入，并且这样的解决思路具备瓶颈，没有很好的扩展性，下面我从低成本、高性能和高扩张性的角度来说说我的一些经验。

1、HTML静态化
其实大家都知道，效率最高、消耗最小的就是纯静态化的html页面，所以我们尽可能使我们的网站上的页面采用静态页面来实现，这个最简单的方法其实也是最有效的方法。但是对于大量内容并且频繁更新的网站，我们无法全部手动去挨个实现，于是出现了我们常见的信息发布系统CMS，像我们常访问的各个门户站点的新闻频道，甚至他们的其他频道，都是通过信息发布系统来管理和实现的，信息发布系统可以实现最简单的信息录入自动生成静态页面，还能具备频道管理、权限管理、自动抓取等功能，对于一个大型网站来说，拥有一套高效、可管理的CMS是必不可少的。

除了门户和信息发布类型的网站，对于交互性要求很高的社区类型网站来说，尽可能的静态化也是提高性能的必要手段，将社区内的帖子、文章进行实时的静态化，有更新的时候再重新静态化也是大量使用的策略，像Mop的大杂烩就是使用了这样的策略，网易社区等也是如此。

同时，html静态化也是某些缓存策略使用的手段，对于系统中频繁使用数据库查询但是内容更新很小的应用，可以考虑使用html静态化来实现，比如论坛中论坛的公用设置信息，这些信息目前的主流论坛都可以进行后台管理并且存储再数据库中，这些信息其实大量被前台程序调用，但是更新频率很小，可以考虑将这部分内容进行后台更新的时候进行静态化，这样避免了大量的数据库访问请求。

2、图片服务器分离
大家知道，对于Web服务器来说，不管是Apache、IIS还是其他容器，图片是最消耗资源的，于是我们有必要将图片与页面进行分离，这是基本上大型网站都会采用的策略，他们都有独立的图片服务器，甚至很多台图片服务器。这样的架构可以降低提供页面访问请求的服务器系统压力，并且可以保证系统不会因为图片问题而崩溃，在应用服务器和图片服务器上，可以进行不同的配置优化，比如apache在配置ContentType的时候可以尽量少支持，尽可能少的LoadModule，保证更高的系统消耗和执行效率。

3、数据库集群和库表散列
大型网站都有复杂的应用，这些应用必须使用数据库，那么在面对大量访问的时候，数据库的瓶颈很快就能显现出来，这时一台数据库将很快无法满足应用，于是我们需要使用数据库集群或者库表散列。

在数据库集群方面，很多数据库都有自己的解决方案，Oracle、Sybase等都有很好的方案，常用的MySQL提供的Master/Slave也是类似的方案，您使用了什么样的DB，就参考相应的解决方案来实施即可。

上面提到的数据库集群由于在架构、成本、扩张性方面都会受到所采用DB类型的限制，于是我们需要从应用程序的角度来考虑改善系统架构，库表散列是常用并且最有效的解决方案。我们在应用程序中安装业务和应用或者功能模块将数据库进行分离，不同的模块对应不同的数据库或者表，再按照一定的策略对某个页面或者功能进行更小的数据库散列，比如用户表，按照用户ID进行表散列，这样就能够低成本的提升系统的性能并且有很好的扩展性。sohu的论坛就是采用了这样的架构，将论坛的用户、设置、帖子等信息进行数据库分离，然后对帖子、用户按照板块和ID进行散列数据库和表，最终可以在配置文件中进行简单的配置便能让系统随时增加一台低成本的数据库进来补充系统性能。

4、缓存
缓存一词搞技术的都接触过，很多地方用到缓存。网站架构和网站开发中的缓存也是非常重要。这里先讲述最基本的两种缓存。高级和分布式的缓存在后面讲述。
架构方面的缓存，对Apache比较熟悉的人都能知道Apache提供了自己的缓存模块，也可以使用外加的Squid模块进行缓存，这两种方式均可以有效的提高Apache的访问响应能力。
网站程序开发方面的缓存，Linux上提供的Memory Cache是常用的缓存接口，可以在web开发中使用，比如用Java开发的时候就可以调用MemoryCache对一些数据进行缓存和通讯共享，一些大型社区使用了这样的架构。另外，在使用web语言开发的时候，各种语言基本都有自己的缓存模块和方法，PHP有Pear的Cache模块，Java就更多了，.net不是很熟悉，相信也肯定有。

5、镜像
镜像是大型网站常采用的提高性能和数据安全性的方式，镜像的技术可以解决不同网络接入商和地域带来的用户访问速度差异，比如ChinaNet和EduNet之间的差异就促使了很多网站在教育网内搭建镜像站点，数据进行定时更新或者实时更新。在镜像的细节技术方面，这里不阐述太深，有很多专业的现成的解决架构和产品可选。也有廉价的通过软件实现的思路，比如Linux上的rsync等工具。

6、负载均衡
负载均衡将是大型网站解决高负荷访问和大量并发请求采用的终极解决办法。
负载均衡技术发展了多年，有很多专业的服务提供商和产品可以选择，我个人接触过一些解决方法，其中有两个架构可以给大家做参考。
硬件四层交换
第四层交换使用第三层和第四层信息包的报头信息，根据应用区间识别业务流，将整个区间段的业务流分配到合适的应用服务器进行处理。　第四层交换功能就象是虚IP，指向物理服务器。它传输的业务服从的协议多种多样，有HTTP、FTP、NFS、Telnet或其他协议。这些业务在物理服务器基础上，需要复杂的载量平衡算法。在IP世界，业务类型由终端TCP或UDP端口地址来决定，在第四层交换中的应用区间则由源端和终端IP地址、TCP和UDP端口共同决定。
在硬件四层交换产品领域，有一些知名的产品可以选择，比如Alteon、F5等，这些产品很昂贵，但是物有所值，能够提供非常优秀的性能和很灵活的管理能力。Yahoo中国当初接近2000台服务器使用了三四台Alteon就搞定了。

软件四层交换
大家知道了硬件四层交换机的原理后，基于OSI模型来实现的软件四层交换也就应运而生，这样的解决方案实现的原理一致，不过性能稍差。但是满足一定量的压力还是游刃有余的，有人说软件实现方式其实更灵活，处理能力完全看你配置的熟悉能力。
软件四层交换我们可以使用Linux上常用的LVS来解决，LVS就是Linux Virtual Server，他提供了基于心跳线heartbeat的实时灾难应对解决方案，提高系统的鲁棒性，同时可供了灵活的虚拟VIP配置和管理功能，可以同时满足多种应用需求，这对于分布式的系统来说必不可少。

一个典型的使用负载均衡的策略就是，在软件或者硬件四层交换的基础上搭建squid集群，这种思路在很多大型网站包括搜索引擎上被采用，这样的架构低成本、高性能还有很强的扩张性，随时往架构里面增减节点都非常容易。这样的架构我准备空了专门详细整理一下和大家探讨。

对于大型网站来说，前面提到的每个方法可能都会被同时使用到，我这里介绍得比较浅显，具体实现过程中很多细节还需要大家慢慢熟悉和体会，有时一个很小的squid参数或者apache参数设置，对于系统性能的影响就会很大，希望大家一起讨论，达到抛砖引玉之效。
