無法在 AWS EC2 瀏覽器上運行 Jupyter 說“無法訪問站點”

Question

我已經在他們的免費套餐上設置了一個 AWS 賬戶，在安裝 Anaconda 和 Jupyter Notebooks 后，我無法通過瀏覽器連接到 Jupyter Notebook。 我得到以下屏幕：

我設置它的過程主要總結在下面的鏈接中：

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

由於無法正常工作，我對上述中型文章流程進行了一些更改。 主要是我的證書中有以下命令

# 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

在我在瀏覽器中輸入必要的鏈接之前，一切似乎都符合預期。 當我在控制台中輸入 Jupyter notebooks 時，我得到以下信息（X 是字母數字，我認為我不應該分享）：

[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

在瀏覽器中以及輸入教程中的內容：

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

我也嘗試過以下方法：

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

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

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

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

這些似乎都不起作用。

如果有人有任何建議，將不勝感激。

謝謝

在重新創建實例之后，這次將安全設置設置為所有流量，而不僅僅是 SSH（感謝 Lamanus），瀏覽器現在只是不斷地嘗試連接，而控制台給出了下面的 output：

我在 Lamanus 的幫助下解決了這個問題。

正如我在編輯中所說，我必須重新創建我的實例，確保將安全設置從 SSH 更改為所有流量。

然后下次我激活我的終端時，我必須將 go 到 certs 文件夾並使用以下命令修改一些證書：

光盤證書

sudo chmod 777 mycert.pem

之后我去了一個屏幕，它要求我要一個令牌。 我提供的是控制台在下面末尾提供給我的令牌

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

所以我把xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx部分復制粘貼到token區。

謝謝
