ES启动报错之引导检测失败

[--16T18::,][ERROR][o.e.b.Bootstrap ] [node-] node validation exception
[] bootstrap checks failed
[]: system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

先给一个官方的说法：https://www.elastic.co/guide/en/elasticsearch/reference/6.4/_system_call_filter_check.html

解决方法：

vim /etc/elasticsearch/elasticsearch.yml       #添加如下两行

bootstrap.memory_lock: false
bootstrap.system_call_filter: false

重启ES
