一、生成“服务器证书文件”

我把生成的“服务器证书文件”取名为tomcat.key（也可以取成abc.keystore，随自己喜欢就好）。简单起见，我把tomcat.key放在C盘根目录下面（我的配置环境为windows，linux类似）。
首先使用JDK自带的工具keytool生成一个“服务器证书”，取名为tomcat.key。

C:\Users\Administrator>keytool -genkey -alias tomcat -keyalg RSA -keystore C:\to
mcat.key
输入keystore密码：
再次输入新密码:
您的名字与姓氏是什么？
[Unknown]：  beelun
您的组织单位名称是什么？
[Unknown]：  beelun
您的组织名称是什么？
[Unknown]：  beelun
您所在的城市或区域名称是什么？
[Unknown]：  beijing
您所在的州或省份名称是什么？
[Unknown]：  beijing
该单位的两字母国家代码是什么
[Unknown]：  cn
CN=beelun, OU=beelun, O=beelun, L=beijing, ST=beijing, C=cn 正确吗？
[否]：  y

输入<tomcat>的主密码
（如果和 keystore 密码相同，按回车）：

C:\Users\Administrator>jdk -version
‘jdk’ is not recognized as an internal or external command,
operable program or batch file.

C:\Users\Administrator>java -version
java version “1.7.0-ea”
Java(TM) SE Runtime Environment (build 1.7.0-ea-b23)
Java HotSpot(TM) Client VM (build 12.0-b01, mixed mode, sharing)

C:\Users\Administrator>

按照提示，输入密码。我输入的密码为123456（注意：此密码在配置server.xml时需要）。其他信息按照提示输入就可以，在输入tomcat主密码时，我直接键入回车，使其和keystore的密码保持一致。

此时，在C盘下面就生成了一个PCKS1.2格式的数字证书文件C:\tomcat.key。

二、配置server.xml文件

修改tomcat\conf目录下面的server.xml文件，添加一项：

<Connector protocol=”org.apache.coyote.http11.Http11Protocol”
port=”8443″ minSpareThreads=”5″ maxSpareThreads=”75″
enableLookups=”true” disableUploadTimeout=”true”
acceptCount=”100″  maxThreads=”200″
scheme=”https” secure=”true” SSLEnabled=”true”
keystoreFile=”C:\tomcat.key” keystorePass=”123456″
clientAuth=”false” sslProtocol=”TLS”/>

需要注意一行“keystoreFile=”C:\tomcat.key” keystorePass=”123456″”，其中keystorefile是你生成的“服务器证书文件”，keystorePass是该服务证书文件的密码。

三、在浏览器地址栏里输入 https://localhost:8443/ 检验一下就OK了。

a) utf-8 everywhere(client, server, collation, everywhere) to support Chinese.

b) Innodb as default engine

Here is what I did:

1) Download latest source(mysql-5.1.44) from MySQL site

2) rpm -i xxx.src.rpm to install the source. By default, the source will be installed to /usr/src/redhat/SOURCES/mysql-5.1.44.

3) Go the root dir of source, run:

CFLAGS=”-O3″ CXX=gcc CXXFLAGS=”-O3 -felide-constructors \
-fno-exceptions -fno-rtti” ./configure \
–prefix=/usr/local/mysql –enable-assembler \
–with-mysqld-ldflags=-all-static \
–with-charset=utf8 \
–with-collation=utf8_general_ci \
–with-plugins=all

Explain: use gcc as compiler; install mysql to /usr/local/mysql; utf8 as default char set; install all plugins including innodb.

During this process, you may see errors saying “I need this, I need that”, use ‘yum‘ to install them.

And ./configure –help will show all possible options.

4) make

5) make install

And /usr/local/mysql will be the rool dir of new mysql installation.

6) Modify /etc/my.cnf. /usr/src/redhat/SOURCES/mysql-5.1.44/support-files/ contains sample configuration files. Note to set below:

[mysqld]

default-storage-engine = INNODB

7) Modify /etc/init.d/mysqld. You may need sym-link to new mysql installation.

Done. Below message should prove the installation is fine:

My dear friends,

Today is my last working day in Microsoft, and it is time for me to start a long-awaited adventure. During past 3 years, many folks impressed me deeply and I hope have a slice of knowledge/skills you have.  After working in such a wonderful place, I possessed enough confidence to face any subtle difficulties ahead. What I got are much more than what I contributed to this company.

What I learned

• How to tackle the most complex problems in the world as a team.
• How to attract most smart people
• How to inspire people
• How to make a great place to work
• How to build the right software right as a team
• How to deliver good news
• How to deliver bad news(This one is harder)
• How to deliver good/bad reviews(One of hardest part of people management)
• How to deliver a speech
• How to handle *angry* customers
• How to educate customers
• How to learn what customers want
• How to sit down with customers and close a deal
• How to run a team of different size in different stage with different goals
• How to make friends(Pop quiz: Do ICs need friends? Are they all about diagram and code?)
• How to approach people and win their support
• How to win an email argument
• How to response to the competition news
• How to beat competitors
• How to build ecosystem
• How to build up a giant company from scratch (If I can say)
• The way how MSFT encourages knowledge sharing – Discussion loop, brown bag, online learning center, in-person training, marc polo, silk road, mentorship, mentor ring, code review, spec review …
• Share ideas – think week paper, idea exchange, …
• The most easy one – How to reply to all with a “good job” message after a product ship
• And many more…

I won’t claim I am a guru in any of areas above because I see what the highest standards are in this company. And I just reach the good(to me) level of combination of these ingredients.

People

• So many great folks including leadership, developer, tester, PM, marketing, sales, support… I can’t say your names since this is public post, but I will memorize how you changed my mind.

and also something unique about me…

In addition to taking part in shipping 3 products…

• Win FOOL(group alias ‘FOOL’) award. I am probably the only person who has this award in greater Asia.(If not, let me know. Maybe we can talk about that.)
• Win Best Business Value award in a startup team
• Win largest number of valid bugs in first team wide bug bash
• Deliver a presentation to the whole STBC in all hands meeting. (Enwei is even listening to me:-)
• Enter final list with a mobile phone innovation idea(Finally it is so smart that one team in US is on the way of building it quietly.)
• Board number of of STBC citizenship committee
• Organizer of Junior Achievement program in STBC
• Posted a question which a technical fellow answered(MSFT have less than 20 technical fellows which are highest technical title one can achieve.)
• Regular guest speaker of SJTU software institution
• Probably the best Java learner in a .NET world
• Probably the developer with most deep business minds, or business man with strong technical background(I call it “Think globally, act locally” as my blog slogan.)

Almost everyone asked about where I am going. This world is undertaking dramatic changes, especially this country. I can’t stay in this huge market to build software for anywhere else except here forever. Life is short, and I won’t forgive myself if time just passes by as “yet another year” way. Pursuing a fair ROI is another factor which won’t be achieved by working for any company. I am happy to complete engagement with Microsoft roughly on schedule.

2010 will be a new exciting start. I will enjoy in any event.

Good luck to us all! (And luck is actually where preparations meet opportunities.)

Taobao Open Platform(TOP)，淘宝开放平台，是淘宝将一些（不是全部）数据（店铺，商品等）通过编程接口开放给开发者。说简单点是这样，一般我们大家都是在网页里面点点点，来装修店铺，买卖东西的，是人肉通过鼠标和键盘完成的。TOP API，可以帮助大家用程序来完成同样的事情。

目标

该文主要回答一下几个问题：

1) 淘宝为什么开放平台？对于开发者意味着什么？

2) 开放了些什么东东？

3) 如何写一个简单的基于开放平台应用？

淘宝开放的缘由

Taobao经过几年的发展，已经成为国内X2C的头块品牌。它发起并完善了广大的网商，用户，以及与之相关的支付，物流，信用等系统。现在基本无人不淘宝。我的一位同事，所有的东西基本上都在taobao上买，还有一位朋友一大爱好就是周末在taobao上买东西。

但淘宝已经差不多到了不得不开放的地步。在内部，大的卖家渴望走出去，店主渴望以某种方式在300w个网店中脱颖而出，各种购买方式层出不穷，团购、限时拍卖等；在外部，社区、sns、购物搜索已经开始直接或间接涉足X2C市场。面对这么多元化的需求，淘宝自己去满足，肯定会力不从心；视而不见，那会引起积怨，累计到一定程度，必然有后来者取而代之。那怎么办？简单。既然这个钱，我不想赚，那就帮别人去赚，但你们得围绕着我来玩。开放应运而生。如果要看fancy版本的同样解释，请看博文：

小前端、大后台 路鹏（淘宝副总裁）

业务方向

现在淘宝主推三大业务方向：独立网店、社区电子商务化、第三方开发的工具海。

· 淘宝不讳言独立网店，真是很令人佩服。独立网店的样品工程就是优衣库，基本思路就是网站的域名和UI是独立网店的，其他的东西都是淘宝的，比如用户、支付、商品信息等。ShopEx在这方面是淘宝的合作伙伴。

· 社区电子商务化。简单来说，就是在bbs（如天涯）和sns（如人人网）中通过TOP API展示淘宝上商品，一但成交，大家分钱。

· 工具海。做垂直行业的商家管理工具，卖给旺铺卖家。

当然还有其他。参考：TOP业务方向

盈利模式

光炒概念，没有盈利模式的事情，我一向是只看不碰。那大多只是烧钱者的游戏，一般人玩儿不起。淘宝开放还是有比较清楚的变现模式的（包括但不限于）：

· 淘宝客佣金。淘宝客是按成交计费的，CPA模式。而且API中允许用户加入一些自定义数据，用于确定购买行为过程中的贡献方，使得分享利润成为可能。以前写过篇文章，就提到分享利润的一个应用。

· 插件分成。插件分为店铺管理插件和淘江湖SNS平台插件。前者是方便管理店铺用的，后者偏重娱乐性，概念类似Facebook的应用。

· 软件销售。C/S模式，或者ShopEx独立网店大多属于这种模式。

· 传统广告。比如你调用淘宝API生成网页，加Google AdSense进入，也是可以的。

参考：TOP盈利模式

API

参考：TOP API文档

API/角色

六个基本角色，权限从低到高依次为：公开查询应用、买家应用、卖家应用、商家应用、高级应用、专业应用。较高角色的权限包含较低角色的权限。

还有三个独立角色，社区应用、媒体应用、淘宝客应用。相互独立，与六个基本角色不存在依赖关系。

API/分类

API操作的对象，有如下11种：用户，产品，类目，商品，交易，评价，物流，店铺，淘宝客，淘江湖(v=2.0)，图片空间。

API基本的命名规则是<namespace>.<object>.<action>，如taobao.item.get用于获取单个商品的详细信息。

API/如何进行API调用

基于REST协议的API。调用接口地址是：

测试环境地址：http://gw.api.tbsandbox.com/router/rest

正式环境地址：http://gw.api.taobao.com/router/rest

TOP会给每个应用分配app_key和app_secret，相当于该应用的用户名和密码。API调用传入的参数分为系统参数（每个API都需要，且格式相同）和API专有参数（随API不同而不同）两类。系统参数中，app_key由系统分配所得，session通过下列方法获得，而sign是根据签名规则生成，其实就是通过一个hash函数完成了加密和校验的双重功能。这和Facebook的那一套东西很像。

参考：TOP API系统级参数定义 How Facebook Authenticates Your Application

Demo

TOP开放的是基于REST的API，和编程语言无关的。下面用Java语言为例，写个hello world。

不用TOP Java SDK的demo：http://open.taobao.com/demo/javaDemo.zip
