jupyter server

[TOC]

首先确认是否安装有python2和3

使用 $ which python2 , $ which python3 查看，一般会返回 /usr/bin/python2 , /usr/bin/python3 ，如果没有，那么就用 $ sudo apt-get install python2 来安装

安装pip,ipython,jupyter

sudo apt-get install python-pip安装python2版本的pip

sudo -H pip install --upgrade pip 更新pip

sudo apt-get install ipython 安装ipython

sudo apt-get install ipython-notebook 安装ipython

sudo -H pip install jupyter 使用pip安装jupyter

此时所有需要的包都安装完成了，如果是在本地使用jupyter，那么直接输入 $ jupyter notebook ,然后在浏览器中输入 localhost:8080 就可以正常使用了

配置jupyter server

$ jupyter notebook --generate-config 首先生成jupyter的配置文件，文件名为 jupyter_notebook_config.py ，存储于 ~/.jupyter 中

$ ipython 打开ipython进行密码设置，输入以下内容

12345

In [1]: from notebook.auth import passwdIn [2]: passwd()Enter password:Verify password:Out[2]: 'sha1:67c9eXXX'

$ openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mykey.key -out mycert.pem

接下来在 jupyter_notebook_config.py 文件中添加如下信息：

# Set options for certfile, ip, password, and toggle off# browser auto-openingc.NotebookApp.certfile = u'/absolute/path/to/your/certificate/mycert.pem'
c.NotebookApp.keyfile = u'/absolute/path/to/your/certificate/mykey.key'
# Set ip to '*' to bind on all interfaces (ips) for the public serverc.NotebookApp.ip = '*'
c.NotebookApp.password = u'sha1:bcd259ccf...<your hashed password here>'
c.NotebookApp.open_browser = False
# It is a good idea to set a known, fixed port for server accessc.NotebookApp.port = 9999

现在在非 .jupyter 目录运行 $ jupyter notebook,得到如下信息表示jupyter server已成功运行

Copy/paste this URL into your browser when you connect for the first time,    to login with a token:        https://localhost:8080/?token=b5f5e11340dcbf4c2e2b0c9b105fc87d5140d575c457aac8

在浏览器上输入 https://<your server ip>:8080 即可看到jupyter server 的界面

添加python3内核

sudo apt-get install python3-pip 安装python3版本的pip
sudo python3 -m pip install ipykernel
python3 -m ipykernel install --user 安装python3的内核

到此，再次运行$ jupyter notebook就可以同时使用puthon2和3了。
