Apache에서 ProxyPass를 통해 서버 정보에 액세스하는 방법은 무엇입니까?

뒤에는 3개의 웹 서버(a, b, c)가 있고 모두 Apache와 RHEL 8을 실행하는 로드 밸런서가 있습니다. 내가 하고 싶은 일은 상대적으로 간단합니다. http://loadbalancer/a/server-status, http://loadbalancer/b/server-status를 통해 로드 밸런서 뒤에 있는 상자의 Apache 서버 상태를 가져오고 싶습니다. 등.

http://ipofbox:8000/server-status를 사용하여 상자에 직접 액세스하면 서버 상태가 제대로 작동합니다.

로드 밸런서의 httpd.conf에는 다음 줄이 있습니다.

<VirtualHost *:80>

편집하다:지금은 지나간 것 같은데 이번에는 400불량요청을 받았습니다. 요청을 처리하는 백엔드 서버의 오류 로그에는 다음이 표시됩니다.

[auth_digest:error] [pid 9105:tid 139830629422848] [client ***.***.***.***:50720] AH01786: uri mismatch - </a/server-info/> does not match request-uri </server-info/>

다이제스트 인증이 활성화된 경우 로드 밸런서에서 액세스할 때 액세스가 실패하는 것 같습니다. Worksa에는 다음이 있습니다.

Worksa에는 다음이 있습니다.

둘째, http://loadbalancer/worksa/index.html에 액세스하려고 하면 403 Forbidden이 표시되고 worksa에 대한 액세스 로그는 다음과 같습니다.

(13)Permission denied: file permissions deny server access: /var/www/html/index.html.

index.html에서 chmod 0644를 사용했지만 도움이 되지 않는 것 같습니다.

요약하면, http://loadbalancer/a/server-info는 자격 증명을 요청하고 400 Bad Request를 반환하는 반면, http://loadbalancer/a/index.html은 403 Forbidden을 반환합니다.

매우 감사합니다.
