这里的分析工具为innodb_space 使用ruby编写。ruby版本>1,9.3

linux使用的是centos 6.5 所以，我们先安装指定的版本的ruby，关于如何快速安装不同按本的ruby，我这里使用rvm安装。

一：安装指定版本的ruby

Step 1: Upgrade Packages

# yum update

Step 2: Installing Recommended Packages

# yum install gcc-c++ patch readline readline-devel zlib zlib-devel
# yum install libyaml-devel libffi-devel openssl-devel make
# yum install bzip2 autoconf automake libtool bison iconv-devel

Step 3: Install RVM ( Ruby Version Manager )

# curl -L get.rvm.io | bash -s stable

Step 4: Install RVM ( Ruby Version Manager )

# source /etc/profile.d/rvm.sh

Step 5: Install Required Ruby Version

# rvm install 1.9.3

Step 6: Install Another Version ( if Required )

# rvm install 1.8.6

Step 7: Setup Default Ruby Version

# rvm use 1.9.3 --default 

Using /usr/local/rvm/gems/ruby-1.9.3-p545

Step 8: Check Current Ruby Version

# ruby --version

ruby 1.9.3p545 (2014-02-24 revision 45159) [i686-linux]

二：安装最新的gem

wget https://rubygems.org/rubygems/rubygems-2.6.8.tgz

#tar -zxvf rubygems-2.6.8.tgz

#cd rubygems ;ruby setup.rb

#gem install innodb_ruby

三：若出现如下错误，则需要更更改rubygems源

gem sources --remove https://rubygems.org/

gem source -a http://rubygems.org/

或则
gem sources --remove https://ruby.taobao.org/

或则
gem sources --add http://gems.ruby-china.org///再查看一下 gem sources -l

然后gem install innodb_ruby即可
