如何配置NGINX端口重定向？RStudio，Jupyter和JupyterLab

Question

我在端口8000上运行jupyter，在8888上运行jupyter实验室.Nginx配置看起来像（服务器侦听端口80）：

location /julia/ {
  proxy_pass http://localhost:8000;
  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 Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  access_log /var/log/nginx/julia-access.log;
  error_log  /var/log/nginx/julia-error.log;
}

和

location /jupyterlab/ {
  proxy_pass http://localhost:8888;
  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 Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  access_log /var/log/nginx/jlab-access.log;
  error_log  /var/log/nginx/jlab-error.log;
}

/ julia工作正常

/ jupyterlab没有，但服务器：8888工作正常。

为什么呢？要改变什么？

在8787我有RStudio，有nginx配置：

location / {
  proxy_pass http://localhost:8787;
  proxy_redirect http://localhost:8787/ $scheme://$host/;
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection $connection_upgrade;
  proxy_read_timeout 20d;
  access_log /var/log/nginx/rstudio-access.log;
  error_log  /var/log/nginx/rstudio-error.log;
}

也许我应该删除Jupyter（/ julia /）并只留下JupyterLab？
