远程访问aws jupyter notebook超时

  在AWS申请服务器后,连接超时。试了很多方法,都没有成功,困扰了我很久。现在分享一下解决方法。

jupyter notebook远程服务器设置

jupyter官网服务端设置教程 网上也有很多教程,最好还是以官网为准。下面给出不设置ssl简易的jupyter配置

1.设置jupyter 登录密码

有两种方式,一种直接使用jupyter命令自动将密码保存在jupyter_notebook_config.json中,另一种通过from notebook.auth import passwd先生成密码哈希值再在jupyter_notebook_config.py文件中手动配置。这里选择第一种自动配置。注意:如果两种方法都使用的话,按照官网的说法,第一种会覆盖第二种方法的密码。

$ jupyter notebook password
Enter password:  ****
Verify password: ****
[NotebookPasswordApp] Wrote hashed password to /Users/you/.jupyter/jupyter_notebook_config.json

2.生成jupyter_notebook_config.py

$ jupyter notebook --generate-config

选择覆盖原有的文件,生成的文件默认是全部注释的。

3.配置jupyter_notebook_config.py

vim ~/.jupyter/jupyter_notebook_config.py

修改后如下:

c.NotebookApp.ip = '*'   #所有ip均可访问
c.NotebookApp.open_browser = False   #服务器端没有浏览器,所以设置为False
c.NotebookApp.port = 8888 #端口不一定为8888,可随意设置

4.启动jupyter

$ jupyter notebook

出现下面的提示:

[I 02:43:49.989 NotebookApp] [nb_conda_kernels] enabled, 20 kernels found
[W 02:43:50.195 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.

[I 02:43:50.421 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

5.在本地浏览器登录远程jupyter

在本地浏览器输入

xx.xx.xx.xx:8888       #xx.xx.xx.xx为aws实例的公开ipv4地址,而非jupyter显示的172-31-xx-xx,如上面的倒数第二行。

问题

登录不成功,连接超时。

思考

如何和服务器产生连接呢?所以想ping一下服务器。

ping 54.249.xx.xx

显示

Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3

与服务器连接不成功,在网上搜索ping aws不成功的原因,找到原因如下面的链接:

是安全组设置的问题,困扰我两天的问题终于解决,感谢作者的分享。下次在碰到类似的问题,一定要先想本地和终端产生连接的原因。中间自己在虚拟机的服务器搭建了jupyter,用上面的方法配置能够在本地服务器正常登陆。所以问题一定处在aws的配置上面。最后通过ping确定为安全组设置的问题。至此该问题解决。
