错误：
ERROR: [1] bootstrap checks failed [1]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk [2017-10-25T00:18:40,284][INFO ][o.e.n.Node ] [FHZVpeX] stopping ...

解决：
Centos6不支持SecComp，而ES5.2.0默认bootstrap.system_call_filter为true
禁用：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
