在Mac下安裝Fluentd：

sudo gem install fluentd --no-ri --no-rdoc WARNING: ?Error fetching data: too many connection resets (http://production.s3.rubygems.org/specs.4.8.gz) Successfully installed fluentd-0.10.32 1 gem installed

報了這個錯誤。看不懂，google了下

http://stackoverflow.com/questions/10278174/gem-not-installing-showing-connection-error

This problem was caused by the cachefly server.

It seems that the folks over at rubygems.org disabled this mirror and then people's downloads were able to continue successfully.

There is a thread over at rubygems.org?discussing this issue.

不知道怎么解決～于是使用源碼安裝 $ git clone https://github.com/fluent/fluentd.git $ cd fluentd $ rake build Jeweler not available. Install it with: gem install jeweler rake aborted! Don't know how to build task 'build'(See full trace by running task with --trace) 又報錯了～～先裝jeweler，再rake build。 $ sudo gem install jeweler $ rake build /usr/local/Cellar/ruby/1.9.3-p286/lib/ruby/gems/1.9.1/gems/git-1.2.5/lib/git/lib.rb:709: warning: Insecure world writable dir /usr/local in PATH, mode 040777 WARNING: no description specifiedSuccessfully built RubyGemName: fluentdVersion: 0.10.32File: fluentd-0.10.32.gem $ sudo gem install pkg/fluentd-0.10.32.gem 安裝好啦～～接下來測試安裝情況 $ fluentd --setup ./fluent -bash: fluentd: command not found

修改~/.bash_profile，添加

export PATH="/usr/local/Cellar/ruby/1.9.3-p286/lib/ruby/gems/1.9.1/gems/fluentd-0.10.32/bin:$PATH"

再次運行：

$ fluentd --setup ./fluent $ fluentd -c ./fluent/fluent.conf -vv & $ echo '{"json":"message"}' | fluent-cat debug.test?? 2013-03-13 22:41:54 +0800 [trace]: plugin/in_forward.rb:147:initialize: accepted fluent socket object_id=70313253903680 2013-03-13 22:41:54 +0800 debug.test: {"json":"message"} 2013-03-13 22:41:54 +0800 [trace]: plugin/in_forward.rb:188:on_close: closed fluent socket object_id=70313253903680

這是什么東西～，各種谷歌，頭都大了，還是不知道怎么解決，只好向github求助

https://github.com/fluent/fluentd/issues/110 ，

在@?repeatedly?的建議下，

I first heard this issue.
Could you reduce the cause of this case?

For example:

• invoke fluentd without sudo
• remove non-related source or match
• degrade the fluentd version
• etc...

我降低了fluentd 的版本，重新安裝bson_ext版本(保持跟mongo同一版本)，這才解決了問題。具體解決過程在上面issues鏈接里。

第一次在英文網站發表問題，讓英語小學水平的我獲得一點點興奮和滿足，哈哈～

一點點消除錯誤，一點點減少挫敗感
