安装fluentd时配置fluent-plugin-elasticsearch发生的错误

我们在进行fluentd，elasticsearch，kibana环境搭建时，fluentd需要es作为存储的平台，这个时候在配置vi /etc/td-agent/td-agent.conf时<match task.**>host 192.168.0.1 ##### elasticsearch 服务器地址type elasticsearchlogstash_format trueflush_interval 5sinclude_tag_key truetag_key mapred</match>中间涉及到使用elasticsearch，所以我们要安装

fluent-plugin-elasticsearch

/usr/lib64/fluent/ruby/bin/fluent-gem install fluent-plugin-elasticsearch

发生错误：

ERROR:  Error installing fluent-plugin-elasticsearch:
ERROR: Failed to build gem native extension.

/usr/lib64/fluent/ruby/bin/ruby extconf.rb

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include

extconf.rb:39:in `<main>':   Can't find libcurl or curl/curl.h (RuntimeError)

这个是由于我们没有安装 libcurl-devel造成的，我们只要先yum install  libcurl-devel，再次重新

/usr/lib64/fluent/ruby/bin/fluent-gem install fluent-plugin-elasticsearch时就可以顺利进行下去。

如此，fluentd配置成功，可以启动了service td-agent start
