无法在 AWS EC2 浏览器上运行 Jupyter 说“无法访问站点”

Question

我在他们的免费套餐上设置了一个 AWS 账户，在安装 Anaconda 和 Jupyter Notebooks 后，我无法通过浏览器连接到 Jupyter Notebook。我得到以下屏幕：

我设置它的过程主要总结在下面的链接中：

https://medium.com/@josemarcialportilla/getting-spark-python-and-jupyter-notebook-running-on-amazon-ec2-dec599e1c297

由于无法正常工作，我对上述中型文章流程进行了一些更改。主要是我的证书中包含以下命令

# Configuration file for jupyter-notebook.

c = get_config()



# Notebook config this is where you saved your pem cert

c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem'

# listen on all IPs

c.NotebookApp.ip = '0.0.0.0'

# Allow all origins

c.NotebookApp.allow_origin = '*'

# Don't open browser by default

c.NotebookApp.open_browser = False

# Fix port to 8888

c.NotebookApp.port = 8888

在我在浏览器中输入必要的链接之前，一切似乎都按预期进行。当我在控制台中输入 Jupyter notebooks 时，我得到以下信息（X 是字母数字，我认为我不应该分享）：

[I 07:28:56.291 NotebookApp] Writing notebook server cookie secret to /run/user/1000/jupyter/notebook_cookie_secret
[I 07:28:57.297 NotebookApp] JupyterLab extension loaded from /home/ubuntu/anaconda3/lib/python3.7/site-packages/jupyterlab
[I 07:28:57.297 NotebookApp] JupyterLab application directory is /home/ubuntu/anaconda3/share/jupyter/lab
[I 07:28:57.299 NotebookApp] Serving notebooks from local directory: /home/ubuntu
[I 07:28:57.299 NotebookApp] The Jupyter Notebook is running at:
[I 07:28:57.299 NotebookApp] https://(ip-XXX-XX-XX-XXX or XXX.X.X.X):8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
[I 07:28:57.299 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 07:28:57.303 NotebookApp]

To access the notebook, open this file in a browser:
file:///run/user/1000/jupyter/nbserver-29637-open.html
Or copy and paste one of these URLs:
https://(ip-XXX-XX-XX-XXX or XXX.X.X.X):8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

在浏览器中输入教程内容：

https://XXX-X-XX-X-XXX.us-east-2.compute.amazonaws.com:8888

我也尝试过以下方法：

https://XXX-X-XX-X-XXX.us-east-2.compute.amazonaws.com

https://(ip-XXX-XX-XX-XXX 或 XXX.X.X.X):8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

https://ip-XXX-XX-XX-XXX:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

https://ip-XXX.X.X.X:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

这些似乎都不起作用。

如果有人有任何建议，将不胜感激。

谢谢

编辑

在重新创建实例之后，这次将安全设置设置为所有流量，而不仅仅是 SSH（感谢 Lamanus），浏览器现在只是不断尝试连接，而控制台提供以下输出：

我在 Lamanus 的帮助下解决了这个问题。

正如我在编辑中所说，我必须重新创建我的实例，确保将安全设置从 SSH 更改为所有流量。

然后下次激活终端时，我必须转到 certs 文件夹并使用以下命令修改一些证书：

cd 证书

sudo chmod 777 mycert.pem

之后，我进入一个屏幕，它要求我提供令牌。我提供的是控制台在下面末尾提供给我的令牌

https://ip-XXX-XX-XX-XXX:8888/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

于是我把xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx部分复制粘贴到token区。

谢谢
