ubuntu - 从远程服务器运行 jupyter 笔记本的脚本

Question

我有一台运行 jupyter 笔记本的服务器(Ubuntu 服务器 16.04)和一台本地机器(Mac)，我使用 google-chrome 来可视化这些笔记本。为此，我必须:

在服务器中运行 jupyter notebook:

jupyter notebook --no-browser --port=${remotePort}

在我的本地机器上指定一个 SHH 隧道:

ssh -f ${username}@${serverIP} -L ${localPort}:localhost:${remotePort}

为了自动化这个过程，我创建了脚本 jupyter.sh(如下所述)，这样我只在本地机器上运行:

bash jupyter.sh -u myUserNameInServer

它完美无缺。它能够运行前两个步骤，而且它会自动在我的网络浏览器中打开 jupyter 页面。不过，我想知道是否有更好的方法来做到这一点。我将非常感谢您的意见。

提前致谢。

您可以使用默认情况下未激活的“jupyter 配置文件”，因此需要先执行此命令(在您的服务器上):

jupyter notebook --generate-config

然后在“/.jupyter”文件夹中生成的“jupyter_notebook_config.py”中:
取消注释该行并更改值。

通过这种方式，您可以调整配置，例如密码而不是 token 、默认目录、端口等.. 随心所欲地做这可能是在脚本中执行一些“jupyter 配置”然后保留其他所有内容的正确方法。
