Jupyter notebook的安装及远程登陆的配置

环境及工具

1. ubuntu16.04
2. pip
3. python3
4. ipython

安装

官方教程： https://jupyter.readthedocs.io/en/latest/install.html

我是直接使用pip安装。

pip install jupyter

本地运行

jupyter notebook

配置远程登陆

如果你想在windows下的浏览器中连接登陆到jupyter notebook，你需要修改相应的配置。官方教程：https://jupyter-notebook.readthedocs.io/en/stable/public_server.html#securing-a-notebook-server

• 步骤一

找到配置文件， Linux 在：/home/username/.jupyter/jupyter_notebook_config.py ，如果你发现没找到，莫急，我们可以手动生成它。输入下面命令即可。

jupyter notebook --generate-config

• 步骤二

自定义登陆的密码，并将这个密码复制好，下面会用到。首先打开ipython，输入如下：

In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password:
Verify password:
Out[2]: 'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'

• 步骤三

在配置文件jupyter_notebook_config.py修改以下几点，并将这几点的注释取消。这里使用vim打开这个文件，修改完后保存退出。退出时，它可能会报有配置文件内很多信息不该被注释，请忽略它。

c.NotebookApp.ip = '*' #设置远程所有ip可访问
c.NotebookApp.password = u'sha1:bcdccf...'#把刚刚复制的密码粘贴
c.NotebookApp.open_browser = False   #关闭浏览器
c.NotebookApp.port = 9999  #选一个可用的端口

• 步骤四

我们在步骤三种选择了一个端口，默认是8888，但我修改了，因为8888这个端口已经在用。端口9999需要我们做端口转发，千万不要忘了。具体步骤我这里就不啰嗦了。

• 步骤五

 如果不出意外的话，直接运行jupyter notebook 就可以，然后在浏览器中输入http:// [your ip]:your port 即可。但我就恰好出现了下面的报错信息。

Traceback (most recent call last):

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -5] No address associated with hostname

后来我把jupyter notebook命令换成jupyter notebook --allow-root --no-browser --ip=0.0.0.0就ok了。效果如下所示：
