子路径中带有nginx反向代理的Jupyterhub

我有一台Ubuntu服务器，在端口

443

上运行nginx，以提供一些静态内容，在端口

8000

上运行Jupyterhub 0.8，用于Python笔记本电脑（Jupyterhub通过pip安装并作为服务运行（不与Docker一起运行）

我想使用nginx的反向代理将jupyterhub作为子路径进行访问，例如

example.com/jupyterhub

在这里的文档和一些其他讨论（例如）之后，我提出了以下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

https://example.com/jupyterhub

我得到一个502错误。查看nginx

错误。日志

我发现

*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

curl

如前所述，您的问题是您的Jupyter正在https上运行，并且您正在使用http作为您的

代理\u通行证

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

还要确保
https://localhost:8000
，以便
/jupyterhub/
作为url的一部分发送到
代理\u pass
您是否能够卷曲到
http://127.0.0.1:8000/jupyterhub/
？@TarunLalwani不，我得到
curl:（52）来自服务器的空回复
您是否使用docker运行jupyterhub？@TarunLalwani，否，它是通过
pip安装的
并作为服务运行。那么
curl-v呢http://127.0.0.1:8000/
？
