python-3.x - 在 ec2 Ubuntu 实例上启动 Jupyter Notebook

Question

我正在尝试在 AWS EC2 实例上安装 Anaconda、Python 3 和 Jupyter 笔记本。我在实例上运行 Ubuntu。我已经使用 Anaconda 安装了 Python。我已将默认 Python 设置为 Anaconda 版本。我创建了一个 Jupyter notebook 配置文件。在我添加的 Jupyter notebook 配置文件中:

c = get_config()

# Notebook config this is where you saved your pem cert
c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem' 
# Run on all IP addresses of your instance
c.NotebookApp.ip = '*'
# Don't open browser by default
c.NotebookApp.open_browser = False  
# Fix port to 8888
c.NotebookApp.port = 8888

我还使用以下代码为证书创建了一个目录:

mkdir certs
cd certs

sudo openssl req -x509 -nodes -days 365 -newkey rsa:1024 -keyout mycert.pem -out mycert.pem

但是当我尝试使用以下命令运行 Jupiter notebook 时:

jupyter 笔记本

我收到以下错误消息。我的最终目标是能够在 AWS EC2 实例上启动 Jupiter notebook，然后在笔记本电脑上的浏览器中远程连接到它。有谁知道我的问题可能是什么？

错误:

Answer 1

转到您的 AWS 实例安全组，然后像下面的屏幕截图那样配置入站安全组:

如果您确定 AWS 的权限配置正确，请检查您的网络是否未阻止出站流量。当通过 SSH 连接到您的实例时，您可以尝试进行端口隧道:

ssh -i -L 8888:127.0.0.1:8888

然后您就可以在浏览器上访问 localhost:8888 来本地访问 jupyter。
