nginx 重定向到错误的网站

Question

我在 nginx 后面配置了两个节点应用程序运行。 nginx 用作反向代理，一个域重定向到错误的应用程序默认 url,

app1 端口 3000 域 http://www.site1.com and https://www.site1.com

app2 端口 3001 域 http://www.site2.com

http://www.site1.com and https://www.site1.com 工作正常并服务于 app1

但是当 http://www.site2.com 它重定向到 https://www.site2.com 和服务器 app1

但是当请求 http://www.site2.com/someurl 时它服务器 app2

这里是 nginx 配置

站点 1

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        server_name www.site1.com;
        return 301 https://$server_name$request_uri;
}
server {

  listen 443 ssl;

  server_name www.site.com;
  ssl on;
  ssl_certificate /certificate.crt;
  ssl_certificate_key /psa.rsa;
  location / {
      proxy_pass http://localhost:3000;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection 'upgrade';
      proxy_set_header Host $host;
      proxy_cache_bypass $http_upgrade;
      proxy_cookie_path / "/; HTTPOnly; Secure";
  }
}

站点 1 配置文件

server {
        listen 80;
        server_name www.site2.com;
        location / {
                proxy_pass http://localhost:3001;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection ‘upgrade’;
                proxy_set_header Host $host;
                proxy_cache_bypass $http_upgrade;
        }
}

Answer 1

你只有一个 https 服务器 conf，它代理所有对 app1（端口 3000）的请求，它不会为你提供 https 上的 app2。

通过检查请求的 Host header 有条件地代理到 app2 或 app1，例如：

server {
    listen 443 ssl;
    ...
    location / {
        if ($host = 'www.site1.com') {
            proxy_pass http://localhost:3000;
        }
        if ($host = 'www.site2.com') {
            proxy_pass http://localhost:3001;
        }
    }
}
