Fluent安装过程：详细步骤与注意事项

在Mac下安装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-0.10.321 gem installed

报了这个错误。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. 不知道怎么解决～于是使用源码安装
 

$ git clone https://github.com/fluent/fluentd.git

$ cd fluentd

$ rake build

Jeweler not available. Install it with: gem install jewelerrake aborted!Don't know how to build task 'build' (See full trace by running task with --trace)

又报错了～～先装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 040777WARNING:  no description specified  Successfully built RubyGem  Name: fluentd  Version: 0.10.32  File: fluentd-0.10.32.gem

$ sudo gem install pkg/fluentd-0.10.32.gem 安装好啦～～接下来测试安装情况 
   

$ 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"

再次运行：

$ fluentd --setup ./fluent

$ fluentd -c ./fluent/fluent.conf -vv &

$ echo '{"json":"message"}' | fluent-cat debug.test

安装mongo插件

$ sudo gem install fluent-plugin-mongo

这是什么东西～，各种谷歌，头都大了，还是不知道怎么解决，只好向github求助

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

    在@ repeatedly 的建议下，

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，重新安装bson_ext版本(保持跟mongo同一版本)，这才解决了问题。具体解决过程在上面issues链接里。

第一次在英文网站发表问题，让英语小学水平的我获得一点点兴奋和满足，哈哈～

一点点消除错误，一点点减少挫败感
