centos7安装 jupyter

xinhu1300

　　Jupyter Notebook（此前被称为 IPython notebook）是一个交互式笔记本，支持运行 40 多种编程语言。
　　Jupyter Notebook 的本质是一个 Web 应用程序，便于创建和共享文学化程序文档，支持实时代码，数学方程，可视化和 markdown。 用途包括：数据清理和转换，数值模拟，统计建模，机器学习等等

　　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 -xvJf  Python-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
　　# jupyter notebook --generate-config
　　Writing default config to: /root/.jupyter/jupyter_notebook_config.py
　　生成密码
　　# python3
　　Python 3.6.2 (default, Nov  2 2018, 16:17:04)
　　[GCC 4.8.5 20150623 (Red Hat 4.8.5-28.0.1)] on linux
　　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
　　[C 17:02:44.143 NotebookApp] 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
　　[I 17:04:12.761 NotebookApp] Serving notebooks from local directory: /home/sphuser/Python-3.6.2
　　[I 17:04:12.761 NotebookApp] The Jupyter Notebook is running at:
　　[I 17:04:12.761 NotebookApp] http://(jupyterserver or 127.0.0.1):8080/
　　[I 17:04:12.761 NotebookApp] 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
