CentOS7.6 设置Jupyter Lab（anaconda）远程访问，以系统服务运行

安装jupyter lab过程不再赘述。

测试

设置所有本机所有IP均可访问，服务端口为8080，设置启动目录为/root/ipynbs。

由于当前用户为root，出于安全考虑，jupyter lab需要设置--allow-root才能运行。

(base) [root@ecs-9e76 ~]# jupyter lab --ip=0.0.0.0 --port=8080 --notebook-dir='/root/ipynbs' --allow-root
[I 22:49:45.533 LabApp] JupyterLab extension loaded from /root/anaconda3/lib/python3.7/site-packages/jupyterlab
[I 22:49:45.533 LabApp] JupyterLab application directory is /root/anaconda3/share/jupyter/lab
[I 22:49:45.535 LabApp] Serving notebooks from local directory: /root/ipynbs
[I 22:49:45.535 LabApp] The Jupyter Notebook is running at:
[I 22:49:45.535 LabApp] http://ecs-9e76:8080/?token=5c5548b668f5eb1a3c188e9f2c047af3e0fccb111686801d
[I 22:49:45.535 LabApp]  or http://127.0.0.1:8080/?token=5c5548b668f5eb1a3c188e9f2c047af3e0fccb111686801d
[I 22:49:45.535 LabApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[W 22:49:45.538 LabApp] No web browser found: could not locate runnable browser.
[C 22:49:45.538 LabApp] 
    To access the notebook, open this file in a browser:
        file:///root/.local/share/jupyter/runtime/nbserver-13713-open.html
    Or copy and paste one of these URLs:
        http://ecs-9e76:8080/?token=5c5548b668f5eb1a3c188e9f2c047af3e0fccb111686801d
     or http://127.0.0.1:8080/?token=5c5548b668f5eb1a3c188e9f2c047af3e0fccb111686801d

访问http://xx.xx.xx.xx:8080/?token=5c5548b668f5eb1a3c188e9f2c047af3e0fccb111686801d即可访问Jupyter Lab。

设置密码访问

jupyter lab默认采用token访问，不够方便，设置采用密码访问。

输入jupyter notebook password，按提示输入密码。

密码文件保存在配置文件/root/.jupyter/jupyter_notebook_config.json中。

(base) [root@ecs-9e76 ~]# jupyter notebook password
Enter password: 
Verify password: 
[NotebookPasswordApp] Wrote hashed password to /root/.jupyter/jupyter_notebook_config.json
(base) [root@ecs-9e76 ~]# vi /root/.jupyter/jupyter_notebook_config.json
{
    
    
  "NotebookApp": {
    
    
    "password": "sha1:d933b9053eb0:55de430361c7686fdc3ce5462af9804637ead074"
  }
}

修改配置文件

前面测试中直接用参数配置IP、端口等信息，为了便于使用，可在配置文件中做相关配置。

jupyter lab的配置文件有两种：jupyter_notebook_config.py和jupyter_notebook_config.json。

两个配置文件选择其一即可。

1. 通过jupyter_notebook_config.py文件

• 生成配置文件jupyter_notebook_config.py
  输入jupyter notebook --generate-config命令，生成jupyter_notebook_config.py文件。

(base) [root@ecs-9e76 ~]# jupyter notebook --generate-config
Writing default config to: /root/.jupyter/jupyter_notebook_config.py

• 修改配置文件

(base) [root@ecs-9e76 ~]# vi  /root/.jupyter/jupyter_notebook_config.py

修改配置文件，确保以下选项为未注释状态：

c.NotebookApp.ip = '*' 
c.NotebookApp.port = 8080
c.NotebookApp.open_browser = False 
c.NotebookApp.notebook_dir = '/root/ipynbs' 
c.NotebookApp.allow_root = True

2. 通过jupyter_notebook_config.json文件

注意，jupyter_notebook_config.json文件原始内容为：

{
    
    
  "NotebookApp": {
    
    
    "password": "sha1:d933b9053eb0:55de430361c7686fdc3ce5462af9804637ead074"
  }
}

修改上述配置后，对应的jupyter_notebook_config.json文件内容如下：

(base) [root@ecs-9e76 ~]# vi /root/.jupyter/jupyter_notebook_config.json
{
    
    
  "NotebookApp": {
    
    
    "password": "sha1:d933b9053eb0:55de430361c7686fdc3ce5462af9804637ead074",
    "ip" : "*" ,
    "port" : 8080,
    "open_browser" : false ,
    "notebook_dir" : "/root/ipynbs" ,
    "allow_root": true
  }
}

运行效果如下：

(base) [root@ecs-9e76 ~]# jupyter lab
[W 00:47:39.022 LabApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.
[I 00:47:39.028 LabApp] JupyterLab extension loaded from /root/anaconda3/lib/python3.7/site-packages/jupyterlab

以系统服务形式运行jupyter lab

创建/etc/systemd/system/jupyter.service文件，文件内容如下：

[root@ecs-9e76 ~]# vi /etc/systemd/system/jupyter.service
[Unit]
Description=jupyterlab
After=network.service

[Service]
ExecStart=/root/anaconda3/bin/jupyter lab 

[Install]
WantedBy=default.target

启动服务：systemctl start jupyter

[root@ecs-9e76 ~]# systemctl start jupyter

开机启动：systemctl enable jupyter

[root@ecs-9e76 ~]# systemctl enable jupyter
Created symlink from /etc/systemd/system/default.target.wants/jupyter.service to /etc/systemd/system/jupyter.service.
