在亞馬遜 AWS 上安裝 jupyter notebook

Question

我有一些 AWS 服務器，我正在嘗試在其上安裝 jupyter notebook。

我執行以下步驟：

轉到我的主目錄並使用

python3.6 -m venv env

激活 venv

source env/bin/activate

安裝 Jupyter

python -m pip install --upgrade pip

python -m pip install jupyter

運行 jupyter 筆記本

jupyter notebook

在我運行jupyter notebook之前，一切似乎都正常。

我收到以下錯誤：

(env) root@ip-172-51-23-114:/home/USER# jupyter notebook --allow-root

我通過 RStudio 中的終端安裝 python 和 jupter notebook。

我應該嘗試在實例上安裝 chrome 或其他網絡瀏覽器嗎？

Answer 1

根據您配置的網絡權限，您可以嘗試使用域后跟端口連接到 EC2 實例上的 Jupyter 筆記本。 例如，

https://<ec2-address>:<port>

對於us-west-2區域中的示例實例：

https://ec2-52-39-239-66.us-west-2.compute.amazonaws.com:8888/

它可能會提示您在 EC2 身份驗證窗口中輸入令牌，或者您可以簡單地將其附加到上述 URL 的末尾：

https://ec2-52-39-239-66.us-west-2.compute.amazonaws.com:8888/?token=4a83abb3edf214bff5796dae4cf0ed756b1d99972e4134e7
