提示如下，不必理会，等待安装，稍等一会儿（视网络情况）可看到安装进度。
/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.
命令执行完之后

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

执行fluentd -c fluent.conf -vv &
输出

发送数据验证
echo '{"json":"message"}'|fluent-cat debug.test
得到输出
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"}
2012-09-27 17:45:32 +0800: plugin/in_forward.rb:181:on_close: closed fluent socket object_id=95324080
至此安装全部完成。
总结：其实直接进行的是在线安装，提前下载fluent包没用。可直接从安装ruby开始，待验证。
