我正在尝试用这个配置来设置nginx。要访问backend.mygreat.server.com，我必须通过我的公司代理，即myproxy.server.com:80。

因此，我将其添加到/etc/环境中。

https_proxy=myproxy.server.com:80

然而，nginx无法到达https://backend.mygreat.server.com:443。我在nginx日志中看到504作为HTTP状态。

我可以使用wget或curl加载页面(通过公司代理)

  server {
        listen  443;
        server_name  mygreat.server.com;
        ssl  on;
        ssl_protocols  TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;
        ssl_ciphers EECDH+ECDSA+AESGCM:EECDH+aRSA+AESGCM:EECDH+ECDSA+SHA384:EECDH+ECDSA+SHA256:EECDH+aRSA+SHA384:EECDH+aRSA+SHA256:EECDH:EDH+aRSA:!aNULL:!eNULL:!LOW:!RC4:!3DES:!MD5:!EXP:!PSK:!SRP:!SEED:!DSS:!CAMELLIA;

        ssl_certificate /etc/nginx/ssl/mygreat.server.com.pem;
        ssl_certificate_key /etc/nginx/ssl/mygreat.server.com.key;

        access_log  /var/log/nginx/access.ssl.log;

        location / {
          proxy_set_header X-Real-IP  $remote_addr;
          proxy_set_header Host-Real-IP  $http_host;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header X-Real-Pcol http;

          proxy_intercept_errors on;
          error_page 301 302 307 = @handle_redirects;      

          proxy_pass https://backend.mygreat.server.com:443;
        }

        location @handle_redirects {
            set $saved_redirect_location '$upstream_http_location';
            proxy_pass $saved_redirect_location;
        }    
    }

任何帮助都是非常感谢的。

谢谢

下面是nginx的错误日志示例

2017/10/18 06:55:51 [warn] 34604#34604: *1 upstream server temporarily disabled while connecting to upstream, client: <ip-address>, server: mygreat.server.com, request: "GET / HTTP/1.1", upstream: "https://<ip-of-backend>:443/", host: "mygreat.server.com"

如果我在下面运行curl -v https://backend.mygreat.server.com/是响应

因此，首先，我不确定Nginx是否应该尊重http_proxy和https_proxy变量。我没有在同一份文件上找到任何文件。因此，我假设您的问题与nginx不使用代理有关。

所以现在您可以选择使用一些实际使用代理的东西。这就是socat来拯救的地方。

运行套接字转发器

如果有透明代理，则运行

socat TCP4-LISTEN:8443,reuseaddr,fork TCP:<proxysever>:<proxyport>

如果您有连接代理，那么请使用下面的

socat TCP4-LISTEN:8443,reuseaddr,fork PROXY:yourproxy:backendserver:443,proxyport=<yourproxyport>

然后在nginx配置中使用

    location / {
      proxy_set_header X-Real-IP  $remote_addr;
      proxy_set_header Host-Real-IP  $http_host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header X-Real-Pcol http;

      proxy_intercept_errors on;
      proxy_set_header Host backend.mygreat.server.com;
      proxy_pass https://127.0.0.1:8443;
      proxy_redirect https://backend.mygreat.server.com https://mygreat.server.com;
    }

您可能希望使用Systemd服务启动套接字，因此它在启动时运行，并作为服务处理。

Nginx的proxy_pass不支持https代理。可以支持http代理，但是请求url只支持http。

这是一个例子

server {
    listen       8880;
    server_name  localhost;
    location / {
        rewrite ^(.*)$ "://developer.android.com$1";
        rewrite ^(.*)$ "http$1" break;

        proxy_set_header Proxy-Connection Keep-Alive;
        proxy_set_header Host developer.android.com;

        proxy_pass http://127.0.0.1:1080;
        proxy_redirect ~^https?://developer\.android\.com(.*)$ http://$host:8080$1;
    }
}
