[root@localhost ~]# python get-pip.py 

[root@localhost ~]# pip --version

Installing Jupyter with pip

As an existing or experienced Python user, you may wish to install Jupyter using Python’s package manager, pip, instead of Anaconda.

If you have Python 3 installed (which is recommended):

python3 -m pip install --upgrade pip
python3 -m pip install jupyter

If you have Python 2 installed:

python -m pip install --upgrade pip
python -m pip install jupyter

Congratulations, you have installed Jupyter Notebook! To run the notebook, run the following command at the Terminal (Mac/Linux) or Command Prompt (Windows):

jupyter notebook

See Running the Notebook for more details.

安装ipython, jupyter

pip install ipython  
pip install jupyter 

jupyter notebook –generate-config

生成配置文件

[root@ ~]# jupyter notebook --generate-config  
Writing default config to: /root/.jupyter/jupyter_notebook_config.py 

生成密码

[root@localhost ~]# ipython

修改默认配置文件

vi /root/.jupyter/jupyter_notebook_config.py 

c.NotebookApp.ip='*' #设置访问notebook的ip,*表示所有IP,这里设置ip为都可访问  
c.NotebookApp.password = u'sha1:5df252f58b7f:bf65d53125bb36c085162b3780377f66d73972d1' #填写刚刚生成的密文  
c.NotebookApp.open_browser = False # 禁止notebook启动时自动打开浏览器(在linux服务器一般都是ssh命令行访问,没有图形界面的。所以,启动也没啥用)  
c.NotebookApp.port =8889 #指定访问的端口,默认是8888。

firewall-cmd --zone=public --add-port=8888/tcp --permanent
systemctl restart firewalld.service


systemctl stop firewalld.service

启动jupyter notebook

jupyter notebook –allow-root

[root@localhost ~]# jupyter notebook --allow-root           
[W 20:43:08.883 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.
[I 20:43:08.889 NotebookApp] Serving notebooks from local directory: /root
[I 20:43:08.889 NotebookApp] The Jupyter Notebook is running at:
[I 20:43:08.889 NotebookApp] http://(localhost.localdomain or 127.0.0.1):8889/
[I 20:43:08.889 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
^C[I 20:44:19.264 NotebookApp] interrupted

在这里启动后,外网访问不了,解决办法

[root@localhost ~]# yum install -y httpd         

[root@localhost ~]# systemctl start httpd.service

然后你就可以在浏览器里敲入你的地址 http://yourip:8889/
