系统：
centos7
centos7默认是python2，依照官网进行安装
# python -m pip install --upgrade pip
# python -m pip install jupyter
提示出错：
Downloading
setuptools-40.4.3-py2.py3-none-any.whl (569kB)
wheel-0.32.1-py2.py3-none-any.whl
ipython-7.0.1.tar.gz (5.1MB)
Complete output from command python setup.py egg_info:
IPython 7.0+ supports Python 3.5 and above.
When using Python 2.7, please install IPython 5.x LTS Long Term Support version.
Python 3.3 and 3.4 were supported up to IPython 6.x.
See IPython `README.rst` file for more information:
https://github.com/ipython/ipython/blob/master/README.rst
Python sys.version_info(major=2, minor=7, micro=5, releaselevel='final', serial=0) detected.
可以看到，下载的ipython最少需要python3.3的支持
编译python3
安装依赖
# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make
备份
# cd /usr/bin
# mv python python.bak
下载并编译
# wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tar.xz
# tar -xvJfPython-3.6.2.tar.xz
# cd Python-3.6.2
# ./configure prefix=/usr/local/python3
# make && make install
# ln -s /usr/local/python3/bin/python3 /usr/bin/python
验证，同时存在python2和python3
# python -V
Python 3.6.2
# python2 -V
Python 2.7.5
编辑yum和urlgrabber-ext-down
执行yum需要python2，需要修改yum的配置
# vi /usr/bin/yum
#! /usr/bin/python
>>
#! /usr/bin/python2
# vi /usr/libexec/urlgrabber-ext-down
#! /usr/bin/python
>>
#! /usr/bin/python2
依照官网进行安装
# python3 -m pip install --upgrade pip
# python3 -m pip install jupyter

生成配置文件

Writing default config to: /root/.jupyter/jupyter_notebook_config.py

Type "help", "copyright", "credits" or "license" for more information.
>>> from notebook.auth import passwd
>>> passwd()
此时会让你两次输入密码，然后就会生成秘钥
修改配置文件
# vi ~/.jupyter/jupyter_notebook_config.py
# 设置所有IP皆可访问
c.NotebookApp.ip = '0.0.0.0'
c.NotebookApp.password = u'生成的密钥'
# 禁止自动打开浏览器
c.NotebookApp.open_browser = Flase
# 服务端口
c.NotebookApp.port = 8080
这里需要注意的是c.NotebookApp.ip，这个配置项如果按照网上大多数的配置配置为*的话，就会出现下面的错误：
# jupyter notebook

需要注意版本信息，如果notebook为5.6.0以下版本,c.NotebookApp.ip = '*'，为以上版本，则设置为c.NotebookApp.ip = '0.0.0.0'
启动服务
# jupyter notebook
Running as root is not recommended. Use --allow-root to bypass.
根据提示使用root用户启动需要加入参数
# jupyter notebook --allow-root
Serving notebooks from local directory: /home/sphuser/Python-3.6.2
The Jupyter Notebook is running at:
http://(jupyterserver or 127.0.0.1):8080/
Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
打开 IP:指定的端口, 输入密码就可以访问了
