我有一个 Ubuntu 服务器在端口上运行 nginx443以提供一些静态内容，并在端口上8000为 Python 笔记本提供 Jupyterhub 0.8（jupyterhub 通过 pip 安装并作为服务运行（不使用 Docker）。

我想使用 nginx 的反向代理使 jupyterhub 可以作为子路径访问，例如example.com/jupyterhub.

在文档和其他一些讨论（例如这个）之后，我想出了以下 nginx 配置：

server_tokens off;

server {
  listen      80;
  server_name example.com;
  rewrite     ^   https://$server_name$request_uri? permanent;
}

server {
  listen 443 ssl default_server;
  #listen [::]:80 default_server ipv6only=on;

  root /var/www/html;
  index index.php index.html index.htm;

  ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
  ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;

  # Make site accessible from http://localhost/
  server_name localhost;

  # certs sent to the client in SERVER HELLO are concatenated in 
  ssl_certificate
  ssl_session_timeout 1d;
  ssl_session_cache shared:SSL:50m;
  ssl_session_tickets off;


  # modern configuration. tweak to your needs.
  ssl_protocols TLSv1.2;
  ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';
  ssl_prefer_server_ciphers on;

  # HSTS (ngx_http_headers_module is required) (15768000 seconds = 6 months)
  add_header Strict-Transport-Security max-age=15768000;

  # OCSP Stapling ---
  # fetch OCSP records from URL in ssl_certificate and cache them
  ssl_stapling on;
  ssl_stapling_verify on;

  location /jupyterhub/ {
    proxy_pass http://localhost:8000;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-NginX-Proxy true;

    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
  }

  location / {
    try_files $uri $uri/ =404;
  }

  # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000  
  location ~ \.php$ {
    include snippets/fastcgi-php.conf;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
  }
}

另外，我在jupyterhub_conf.py

c.JupyterHub.base_url = u'/jupyterhub'
c.JupyterHub.ip = '127.0.0.1'

当我访问时，https://example.com/jupyterhub我收到 502 错误。看着error.log我发现的 nginx

*13 upstream prematurely closed connection while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: localhost, request: "GET /jupyterhub/ HTTP/1.1", upstream: "http://127.0.0.1:8000/jupyterhub/", host: "example.com"

jupyterhub 的本地人curl给出

$ curl -v http://127.0.0.1:8000/jupyterhub/
*   Trying 127.0.0.1...

正如所讨论的，您的问题是您的 Jupyter 在 https 上运行，并且您使用 http 作为proxy_pass. 您需要将您的 nginx 配置更改为以下

  location /jupyterhub/ {
    proxy_pass https://localhost:8000;
    ...

还要确保 没有尾部斜杠https://localhost:8000，以便将/jupyterhub/其作为 url 的一部分发送到proxy_pass.
