저는 asp.net core로 웹사이트를 만들었고, 예전에는 IIS에서 잘 돌아갔습니다.
이제 Nginx를 사용하여 centos8로 수정합니다.
프로젝트는 URL을 통해 centos8에서 잘 실행됩니다.http://0.0.0.0:5001
Nginx는 역방향 프록시 서버로 사용됩니다. 그러나 로컬 컴퓨터를 통해 웹사이트에 접속한 후 502 Bad Gateway오류가 보고됩니다.
로그인은 다음과 같습니다 error.log.

구글에 검색해보니 비슷한 문제가 너무 많은 것 같네요.
누군가가 내가 그것을 사용해야 한다고 말했다.setsebool -P httpd_can_network_connect 1
시도했지만 문제는 여전히 여기에 있습니다.
나는 단지 초보자입니다. 어떻게 해결할 수 있는지 알려주세요. 감사합니다.
답변1
0.0.0.0유효한 IP 주소가 아닙니다. 백엔드 서버의 올바른 주소를 입력하세요.
답변2
@Gerald Schneider의 도움에 감사드립니다.
다음 두 코드를 수정합니다. upstream backend { server 172.18.92.125:5001; }
프록시패스http://172.18.92.125:5001;
그리고 마침내 작동합니다.
