ERROR: 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

 

위와 같은 에러메세지가 나는 이유는 엘라스틱서치를 실행할 때 부트스트랩(bootstrap) 과정을 거치는데 이때 컴퓨터의 System Call 필터가 설치되지 않을 때 발생한다. 

 

https://www.elastic.co/guide/en/elasticsearch/reference/master/_system_call_filter_check.html

 

elasticsearch.yml 에서 다음과 같은 옵션을 추가한다.

bootstrap.system_call_filter: false
