Jupyter笔记本SSH隧道错误“签名数据库无法打开”

问题描述 投票：0回答：1

我的大学有一台Linux机器，校园里有强大的Jupyter。以下是我通过Windows笔记本电脑登录远程服务器并在服务器上运行Jupyter笔记本的步骤，可以通过ssh隧道在我的本地浏览器上进行编辑，但它总是给我同样的错误：

  1. 在远程服务器上安装anaconda和Jupyter
  2. 创建我的环境并激活它
  3. 对于SSH隧道，这是我在CMD上连接到远程服务器的方式： Ssh –L 8000(on my laptop):localhost:8889(on remote server) <MyUserID>@<RemoteServerIP>
  4. 在此之后，它要求我的密码，然后我进入远程服务器
  5. 要激活anaconda，我使用以下命令： source $HOME/anaconda3/bin/activate
  6. 进入anaconda后，我激活我的环境： conda activate <env_name>
  7. 进入环境后，启动jupyter笔记本，我输入： jupyter notebook 要么 jupyter notebook --no-browser --port=8889
  8. 然后它显示： [I 09:04:06.122 NotebookApp] Writing notebook server cookie secret to /run/user/148037468/jupyter/notebook_cookie_secret [I 09:04:06.881 NotebookApp] Serving notebooks from local directory: <directoryname> [I 09:04:06.881 NotebookApp] The Jupyter Notebook is running at: [I 09:04:06.881 NotebookApp] http://localhost:8889/ [I 09:04:06.881 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation). [I 09:05:10.507 NotebookApp] 302 GET / (::1) 1.43ms
  9. 然后在我的笔记本电脑上输入： localhost:8000 它将我重定向到登录页面，我在jupyter笔记本中成功查看了我的目录，然后单击.ipynb文件
  10. 在此步骤之后，它永远不会加载笔记本并在笔记本上显示以下错误： 无法建立与笔记本服务器的连接。笔记本电脑将继续尝试重新连接。检查网络连接或笔记本服务器配置。

它在终端上给出以下错误：

Jupyter笔记本不断显示：

"Connecting to terminal"

我不知道如何解决这个问题。我是Linux新手。 sudo命令都不起作用，因为我不是admin /或具有这些权限

这个设置对我的论文是必要的。

linux ssh anaconda jupyter-notebook ssh-tunnel

这可能是问题所在：您的笔记本存储签名（https://jupyter-notebook.readthedocs.io/en/stable/security.html），告诉浏览器在打开笔记本时是否信任任何javascript和html。它将它们存储在SQLite数据库中。看来如果这个数据库文件在NFS上，可能会出现锁定问题：

因此，将文件移动到服务器上的本地文件夹可能会有效，并将NotebookNotary.db_file指向那里。
