EC2上的Jupyter:SSL错误 [英] Jupyter on EC2: SSL Error

问题描述

我正在尝试从EC2提供Jupyter笔记本电脑，但出现SSL错误. 我正在使用此AMI:TensorFlow GPU - @nottombrown (ami-8ed4d0e4).我使用了自签名证书，这可能是问题的一部分.

I'm trying to serve a Jupyter notebook from EC2 but I'm getting an SSL error. I'm using this AMI: TensorFlow GPU - @nottombrown (ami-8ed4d0e4). I used a self-signed certificate and that might be part of the problem.

我查看了其他类似错误的SO帖子，例如此，此和

I've looked at several other SO posts that have a similar error such as this, this and this, but they're getting the error in a quite different context and I can't figure out how to get the solutions (such as setting verify=False) to work for me.

推荐答案

此错误表示找不到SSL证书.

如果尚未创建SSL证书:

通过在命令行中键入以下内容(从您的主目录开始)来创建一个:

Create one by typing the following into the command line (starting at your home directory):

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

(摘自这些说明 )

现在您已经有了SSL证书:

您需要告诉Jupyter在哪里找到它.

You need to tell Jupyter where to find it.

看看是否有jupyter_notebook_config.py(或使用jupyter notebook --generate-config生成).

Take a look at jupyter_notebook_config.py if you have one (or generate one using jupyter notebook --generate-config).

确保您具有以下行:

c.NotebookApp.certfile = u'/home/ubuntu/certs/mycert.pem' #location of your certificate file

(请参见 Jupyter Notebook文档)

，并确保您的自签名SSL证书实际上位于该位置.一个常见的错误是例如将certs与.certs混合在一起.这样的错误将导致Jupyter无法找到您的SSL证书，并会导致您得到错误.

and make sure that your self-signed SSL certificate is actually at that location. A common mistake is to mix up certs with .certs for example. A mistake like this will result in Jupyter not being able to find your SSL certificate and that'll result in the error that you're getting.
