安裝ruby
rz ruby-1.9.3-p0.tar.gz
tar zxvf ruby-1.9.3-p0.tar.gz 
cd ruby-1.9.3-p0 
./configure
make 
make install
驗證ruby
[root@Server201 ruby-1.9.3-p0]# ruby -v
得到提示信息
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-linux]

執行安裝
 gem install fluentd 

提示如下，不必理會，等待安裝，稍等一會兒（視網絡情況）可看到安裝進度。
/usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
命令執行完之後


執行fluentd --setup 
提示Installed /etc/fluent/fluent.conf.


執行fluentd -c fluent.conf -vv &
輸出

發送數據驗證
echo '{"json":"message"}'|fluent-cat debug.test
得到輸出
2012-09-27 17:45:32 +0800: plugin/in_forward.rb:140:initialize: accepted fluent socket object_id=95324080
2012-09-27 17:45:32 +0800 debug.test: {"json":"message"}

至此安裝全部完成。
總結：其實直接進行的是在線安裝，提前下載fluent包沒用。可直接從安裝ruby開始，待驗證。
