解决
问题原因：因为 Centos6 不支持 SecComp，而 ES5.2.1 默认bootstrap.system_call_filter 为 true 进行检测，所以导致检测失败，失败后直接导致 ES 不能启动。详见 ：
https://github.com/elastic/elasticsearch/issues/22899
解决方法：在 elasticsearch.yml 中配置bootstrap.system_call_filter 为 false，注意要在Memory下面:
bootstrap.memory_lock: false bootstrap.system_call_filter: false
