当服务器配置好 Python, Jupyterlab 后，访问总是通过 8888 端口，出于某些原因，想要为其配置二级页面，这样当想要更改端口时只需要修改一下配置，而不需要再次记忆到底是打开了哪个端口，只需要记住二级页面 web 地址就可以。本篇不介绍如何配置 Jupyterlab，而是假设已经配置好了 Jupyterlab，且申请了域名，直接说如何通过 nginx 配置 Jupyterlab.

安装 nginx

sudo apt update
sudo apt install nginx
sudo systemctl status nginx.service
sudo systemctl start nginx.service
sudo systemctl enable nginx.service

配置 Jupyterlab

# 生成 jupyterlab 配置文件
jupyter notebook --generate-config
# 修改配置
vim .jupyter/jupyter_notebook_config.py
# 修改如下内容
c.NotebookApp.base_project_url = '/jupyter'
c.NotebookApp.ip = '0.0.0.0'
# 或者修改如下内容
c.NotebookApp.base_url = '/jupyter'
c.NotebookApp.ip = '0.0.0.0'

#  配置 nginx
cat /etc/nginx/nginx.conf
# 修改如下内容
server {
        listen       80;
        server_name  www.googj.com;
        location /jupyter {
            proxy_pass          http://127.0.0.1:8888;
            proxy_set_header    Host $host;
            proxy_set_header    X-Real-Scheme $scheme;
            proxy_set_header    X-Real-IP $remote_addr;
            proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_http_version  1.1;
            proxy_set_header    Upgrade $http_upgrade;
            proxy_set_header    Connection "upgrade";
            proxy_read_timeout  120s;
            proxy_next_upstream error;
        }
    }
