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

1. <match task.**>
2. host 192.168.0.1 ##### elasticsearch 服务器地址
3. type elasticsearch
4. logstash_format true
5. flush_interval 5s
6. include_tag_key true
7. tag_key mapred
8. </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.rbchecking for curl-config... nochecking for main() in -lcurl... no*** extconf.rb failed ***Could not create Makefile due to some reason, probably lack ofnecessary libraries and/or headers.

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
