    [挖坑笔记]Centos7折腾Jupyter Notebook

    最近学Python 偶然间发现了Jupyter Notebook这个神奇的工具 于是给自己挖了个坑

    Anaconda版本安装

    Anaconda已经自动为你安装了Jupter Notebook及其他工具,还有python中超过180个科学包及其依赖项。
    你可以通过进入Anaconda的官方下载页面自行选择下载

    wget https://repo.anaconda.com/archive/Anaconda3-2019.03-Linux-x86_64.sh
    bash Anaconda3-2019.03-Linux-x86_64.sh
    

    如果提示bunzip2: command not found那么我们安装下bunzip2即可

    yum install -y bzip2
    

    常规来说,安装了Anaconda发行版时已经自动为你安装了Jupyter Notebook的,但如果没有自动安装,那么就在终端(Linux或macOS的“终端”,Windows的“Anaconda Prompt”,以下均简称“终端”)中输入以下命令安装:

    conda install jupyter notebook
    

    如果提示conda command not found那么我们执行下下面的代码即可

    source ~/.bash_profile
    

    使用PIP安装

    我自己还没折腾明白先不写了

    运行Jupyter Notebook

    默认端口启动

    jupyter notebook
    

    报错

    [root@iZj6c60t3bjdrsrm8ojftuZ ~]# jupyter notebook
    [I 21:17:23.827 NotebookApp] Writing notebook server cookie secret to /run/user/0/jupyter/notebook_cookie_secret
    Traceback (most recent call last):

        sock.bind(sockaddr)
    OSError: [Errno 99] Cannot assign requested address
    

    解决方案:添加启动参数

    jupyter notebook --ip=0.0.0.0 --no-browser --allow-root
    

    出现如下信息说明启动成功

    [root@iZj6c60t3bjdrsrm8ojftuZ ~]# jupyter notebook --ip=0.0.0.0 --no-browser --allow-root
    [I 21:20:12.204 NotebookApp] JupyterLab extension loaded from /root/anaconda3/lib/python3.7/site-packages/jupyterlab
    [I 21:20:12.204 NotebookApp] JupyterLab application directory is /root/anaconda3/share/jupyter/lab
    [I 21:20:12.205 NotebookApp] Serving notebooks from local directory: /root
    [I 21:20:12.206 NotebookApp] The Jupyter Notebook is running at:
    [I 21:20:12.206 NotebookApp] http://(iZj6c60t3bjdrsrm8ojftuZ or 127.0.0.1):8888/?token=d547f7ee68511fe93f6697ece677ce730fc67ba2c7d0343e
    [I 21:20:12.206 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
    [C 21:20:12.210 NotebookApp] 
    
        To access the notebook, open this file in a browser:
            file:///run/user/0/jupyter/nbserver-30440-open.html
        Or copy and paste one of these URLs:
            http://(iZj6c60t3bjdrsrm8ojftuZ or 127.0.0.1):8888/?token=d547f7ee68511fe93f6697ece677ce730fc67ba2c7d0343e
    

    访问http://(iZj6c60t3bjdrsrm8ojftuZ or 127.0.0.1):8888/?token=d547f7ee68511fe93f6697ece677ce730fc67ba2c7d0343e即可访问您的页面(注意修改地址)。
    使用过程中不要关闭终端如果想要关闭后继续运行可以使用screen

    screen -S jupyter  #创建一个jupyter的窗口
    jupyter notebook --ip=0.0.0.0 --no-browser --allow-root  ##执行命令
    ctrl+a+z  #将程序放到后台退出
