Jupyter notebook无法为远程访问提供服务

Question

我正在linux服务器(Red Hat 4.8.5)上配置jupyter notebook，.I想使用远程客户端访问jupyter notebook。

首先，我生成了一个配置文件：

jupyter notebook --generate-config

然后我修改了配置文件/root/.jupyter/jupyter_notebook_config.py

c.NotebookApp.ip="0.0.0.0"
c.NotebookApp.allow_origin='*'
c.NotebookApp.open_browser=False
c.NotebookApp.password=u"sha1:16715d2ac300:ee938c81001cfd0841f8bf1441bd02038b62965e"
c.NotebookApp.port=9999
c.NotebookApp.notebook_dir='/home/jupyter_notebook'

最后，我运行jupyter笔记本：

jupyter notebook --config /root/.jupyter/jupyter_notebook_config.py --allow-root

但是，jupyter只是在localhost上运行服务器：

[root@localhost home]# jupyter notebook --allow-root --config /root/.jupyter/jupyter_notebook_config.py 
[I 18:22:45.287 NotebookApp] Serving notebooks from local directory: /home/jupyter_notebook
[I 18:22:45.287 NotebookApp] The Jupyter Notebook is running at:
[I 18:22:45.287 NotebookApp] http://(localhost or 127.0.0.1):9999/
[I 18:22:45.287 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

当我使用相同的配置文件在我的阿里云服务器(Ubuntu 16)上运行jupyter notebook时，它工作了：

[I 17:48:59.388 NotebookApp] Serving notebooks from local directory: /home/jupyter_notebook
[I 17:48:59.388 NotebookApp] The Jupyter Notebook is running at:
[I 17:48:59.389 NotebookApp] http://(iZbp14dhkm7uc5lnu5j510Z or 127.0.0.1):8888/
[I 17:48:59.389 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

我不知道问题出在哪里。我找了很多，但就是找不到解决方案。

欢迎任何建议。

Answer 1

我已经解决了这个问题。这是因为我的服务器的9999端口没有连接到互联网。
