[SonarQube] SonarQube(소나큐브) 구동시 vm.max_map_count Error(에러)

SonarQube(소나큐브)를 설치 후 구동시 시스템 설정에 따라서 구동이 되지 않고 아래와 같은 vm.max_map_count 관련 Error(에러)를 발생하는 경우가 있다. 

해당 경우는 vm.max_map_count의 설정값이 어플리케이션에서 필요로 하는 수보다 작음에 따라서 발생하는 경우이다.

max_map_count

프로세스가 사용할 수 있는 메모리 맵 영역의 최대 수를 지정합니다. 대부분의 경우 기본값으로 65530이 적절합니다. 애플리케이션에 이 파일 보다 많은 수를 매핑해야 하는 경우 이 값을 늘립니다.

이제 해당 vm.max_map_count에 설정된 값 변경을 통해서 현재 Error를 해결 해보도록 하자.

1. 시스템 vm.max_map_count 설정 값 확인

• $ sysctl -a | grep vm.max_map_count

# vm.max_map_count 설정값 확인
$ sysctl -a | grep vm.max_map_count
vm.max_map_count = 65536

2. 시스템 vm.max_map_count 설정 값 변경

• $ sysctl -w vm.max_map_count=262144

# vm.max_map_count 설정값 변경
$ sysctl -w vm.max_map_count=262144
vm.max_map_count = 262144

# vm.max_map_count 설정값 확인
$ sysctl -a | grep vm.max_map_count
vm.max_map_count = 262144

참고로 vm.max_map_count Error의 경우 elastic 구동시에도 많이 발생하는 Error 이다.
