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. Check the mkmf.log file for moredetails. You may need configuration options.Provided configuration options: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=/usr/lib64/fluent/ruby/bin/ruby --with-curl-dir --without-curl-dir --with-curl-include --without-curl-include=${curl-dir}/include --with-curl-lib --without-curl-lib=${curl-dir}/lib --with-curllib --without-curllibextconf.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
