Install Cassandra with Ruby 1.9.1 on Windows
To get it done is not easy. I spent a whole day to figure out the various compatibility issues along the way out.
Now there still might be potential issues, but it works by my rough test.
Step 1: Install Apache Cassandra
You may know that the Ruby gem cassandra will do it for you.
To me, I simply want to keep Cassandra independent from Ruby stuff, to ease the upgrade and administration.
Refer to my blog "Setup Cassandra on Windows"
(http://blog.csdn.net/goodxp/archive/2010/02/26/5327732.aspx) for details.
Step 2: Install Thrift (0.2.0)
If you do "gem install cassandra", it should install thrift automatically (being a dependency).
However, there is a compatibility issue on thrift with Ruby 1.9, so to fail Cassandra gem installation.
It will be better to install thrift first and fix it before installing cassandra gem.
Refer to my blog "fix thrift 0.2.0 installation with ruby 1.9.1"
(http://blog.csdn.net/goodxp/archive/2010/02/28/5333145.aspx) for details.
Step 3: Install gem Cassandra
This part is easy:
$ gem install cassandra
Do NOT do this: "$ cassandra_helper cassandra". It does not work.
I did not dig deeper since I already have a working up-to-date version of Cassandra 0.5.0 installed.
Switch to Cassandra bin folder and start cassandra server:
$ cassandra -f
Open another command console window:
$ irb
irb> require 'rubygems'
irb> require 'cassandra'
If you see a warning pop-up window asking for "msvcrt-ruby18.dll", do this:
irb> quit
$ gem uninstall json
Don't worry, Ruby 1.9 has a good json support.
Now run irb again as above, and then:
irb> include Cassandra::Constants
irb> db = Cassandra.new 'Keyspace1'

三者之间区别并不像你想的那么难，也不会像有些文章写的那么长。挺简单的。
相同之处：三者均在kernel中定义的，均含有包含进某物之意。
不同之处：
1、requre,load用于文件，如.rb等等结尾的文件。
2、include则用于包含一个文件(.rb等结尾的文件)中的模块。
3、requre一般情况下用于加载库文件，而load则用于加载� ......

When I try the command "gem install thrift" with Ruby 1.9.1, I got a compilation error with something related to a C function "strlcpy()".
Then I searched the web. It seems I am not alone and the community know it.
However I do not want to wait for official update, I want to ......
