访问服务器 Jupyter Lab 或 Notebook 并使用 Nginx/Caddy 反向代理

安装并访问服务器上的 JupyterLab，易错点在于 nodejs 需要较新版本和添加 sha1 密钥，可选自启动和基于 Nginx 的反向代理。

本文以 Debian/Ubuntu 为例

Jupyter Notebook

安装

pip install notebook

配置

生成默认配置 jupyter notebook --generate-config

打开 vim .jupyter/jupyter_notebook_config.py 配置文件

修改并取消注释（可以用vim搜索关键词）

c.NotebookApp.allow_root = True
c.NotebookApp.base_url = '/notebook'
c.NotebookApp.ip = '0.0.0.0'
c.NotebookApp.notebook_dir = 'JupyterLab'
c.NotebookApp.open_browser = False
c.NotebookApp.password = '<上面保存的sha1值>'
c.NotebookApp.port = 8888

启动

python3 -m notebook

自启动

vim /etc/systemd/system/jupyter-notebook.service

写入如下代码

[Unit]
Description=Jupyter Notebook
After=network.target
[Service]
Type=simple
ExecStart=/home/aaa/.local/bin/jupyter-notebook --config=/home/aaa/.jupyter/jupyter_notebook_config.py
User=aaa
WorkingDirectory=/home/aaa/
Restart=always
RestartSec=10
[Install]
WantedBy=multi-user.target

将aaa改为自己的用户名，路径等自行修改

启动 Jupyter Notebook

systemctl enable jupyter-notebook
systemctl start jupyter-notebook

反向代理参考https访问章节

Jupyter Lab

安装 JupyterLab

安装 pip 与 JupyterLab

sudo apt update
sudo apt install python3
sudo apt install pip3
pip3 install jupyterlab

添加PATH

export PATH=$PATH:/path/to/jupyterlab

echo $PATH

安装较新版本 nodejs

添加 apt 源文件并更新源:

curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash -

安装 nodejs 与 npm

sudo apt install nodejs

查看 nodejs 版本

npm --version

配置 JupyterLab

生成配置文件

jupyter lab --generate-config

创建哈希密码

利用ipython创建密码

from jupyter_server.auth import passwd
passwd(algorithm='sha1')
# 输入两次密码并保存sha1值

修改 JupyterLab 配置文件

mkdir ~/JupyterLab

打开配置文件

vim ~/.jupyter/jupyter_lab_config.py

修改并取消注释（可以用vim搜索关键词）

c.ServerApp.allow_root = True
c.ServerApp.base_url = '/jupyter'
c.ServerApp.ip = '0.0.0.0'
c.ServerApp.notebook_dir = 'JupyterLab'
c.ServerApp.open_browser = False
c.ServerApp.password = '<上面保存的sha1值>'
c.ServerApp.port = 8080

:wq 保存并退出

构建 JupyterLab 并启动

jupyter lab build --dev-build=False --minimize=False

nohup jupyter lab &

到现在为止已经可以用 http://公网ip:8080 访问 JupyterLab，后文介绍使用 https 访问以及开机自启动

https 访问

Nginx

将下列代码添加到 nginx 配置文件 (/etc/nginx/nginx.conf)

client_max_body_size 1G;
location /jupyter {
        proxy_pass   http://127.0.0.1:8080;
        proxy_connect_timeout 3s;
        proxy_read_timeout 5s;
        proxy_send_timeout 3s;
        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_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
    };
location /notebook {
        proxy_pass   http://127.0.0.1:8888;
        proxy_connect_timeout 3s;
        proxy_read_timeout 5s;
        proxy_send_timeout 3s;
        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_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_redirect off;
    };

Caddy

将下列代码添加到 Caddyfile

your_domain_name

reverse_proxy /jupyter/* 127.0.0.1:8080
reverse_proxy /notebook/* 127.0.0.1:8888

重新读取 Caddyfile 并启动 Caddy

caddy reload && caddy start

开机自启动

使用 systemctl 管理

vim /etc/systemd/system/jupyter.service
