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 00:47:39.030 labapp] serving notebooks from local directory: /root/ipynbs

[i 00:47:39.030 labapp] use control-c to stop this server and shut down all kernels (twice to skip confirmation).
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.
