나는 아직 nginx를 모른다. DevOps 담당자가 우리 앱을 위해 잠시 전에 하나를 설정했습니다.
이것이 nginx.conf그가 설정한 것입니다.

proxy_cache_valid 200 302 10m;
proxy_cache_valid 404 1m;

}
include특별히 앱용인 이와 유사한 다른 파일이 있다는 것을 알 수 있습니다.
#proxy_cache_path /home/html_catch levels=1:2 keys_zone=appbacktocartcocatch:2m max_size=50m;

upstream appbacktocartco {

server localhost:3001;
}
server {
listen 145.239.24.196:80;
server_name app.backtocart.co;
location / {
proxy_cache appbacktocartcocatch;

proxy_set_header X-Forwarded-Proto $scheme;

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://appbacktocartco;
proxy_read_timeout 90;
}
listen 443 ssl; # managed by Certbot

ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
if ($scheme != "https") {
return 301 https://$host$request_uri;
} # managed by Certbot
}
이제 포트 5000에서 이와 같은 다른 앱을 실행하면 됩니다. 이 파일을 복사하여 몇 가지 사항을 변경한 다음 nginx를 다시 시작했지만 이해할 수 없는 오류가 발생했습니다. 이것 좀 도와주실 수 있나요?
편집하다
내가 시도한 방법은 다음과 같습니다.
# proxy_cache_path /home/html_catch levels=1:2 keys_zone=appbacktocartcocatch:2m max_size=50m;
# proxy_cache_key "$scheme$request_method$host$request_uri$is_args$args";
# proxy_cache_valid 200 302 10m;
# proxy_cache_valid 404 1m;
upstream appbacktocartco {
# server localhost:3000;
server localhost:5000;
}
server {
listen 145.239.24.196:80;
server_name chatservice.backtocart.co;
location / {
proxy_cache chatservicebacktocartcocatch;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://chatservicebacktocartco;
proxy_read_timeout 90;
}
}
그럼 내가 할게
/etc/init.d/nginx restart
그리고 얻다

답변1
업스트림을 구성하는 구성 파일에 오류가 있습니다.
upstream appbacktocartco {
# server localhost:3000;
server localhost:5000;
}
이 작업을 수행하려면 업스트림에 대해 다른 이름을 사용해야 합니다.
또한 두 번째 구성 파일에서 사용하는
proxy_pass http://chatservicebacktocartco;
해당 업스트림과 일치해야 합니다.
또한 오류 메시지( nginx: [emerg] duplicate upstream "appbacktocartco")에서는 이를 문제로 지정합니다.
