从远程服务器运行Jupyter Notebook的脚本 [英] Script to run jupyter notebooks from remote server

问题描述

我有一台运行jupyter笔记本的服务器(Ubuntu服务器16.04)，还有一台使用google-chrome可视化这些笔记本的本地计算机(Mac).为此，我必须:

I have a server (Ubuntu server 16.04) that runs jupyter notebooks, and a local machine (Mac) where I use google-chrome to visualize these notebooks. To do so, I have to:

1. 在服务器中运行jupyter笔记本:

1. Run jupyter notebook in the server:

jupyter笔记本--no-browser --port = $ {remotePort}

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

在我的本地计算机上指定一个SHH隧道:

Specify a SHH tunnel in my local machine:

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

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

要自动执行此过程，我创建了脚本jupyter.sh(如下所述)，因此我只能在本地计算机上运行:

To automate this process, I've created the script jupyter.sh (described below), such that I only run on my local machine:

bash jupyter.sh -u myUserNameInServer

它完美无瑕.它能够运行前两个步骤，并且会自动在我的Web浏览器中打开jupyter页面.不过，我想知道是否有更好的方法可以做到这一点.非常感谢您的评论.

It works flawlessly. It's able to run the previous two steps plus it automatically open the jupyter page in my web-browser. Still, I would like to know if there is a better way to do this. I would greatly appreciate your comments.

谢谢.

推荐答案

您可以使用默认情况下未激活的"jupyter配置文件"，因此需要在服务器上执行以下命令:

You can use the "jupyter config file" wich is not activated by default so need to do this command fisrt (on your server):

jupyter notebook --generate-config

然后在"/.jupyter"文件夹中生成的"jupyter_notebook_config.py"中: 取消注释行并更改值.

Then in the generated "jupyter_notebook_config.py" in the "/.jupyter" folder : uncomment the line and change the value.

通过这种方法，您可以调整配置，例如密码而不是令牌，默认目录，端口等..随心所欲，这可能是在脚本中执行某些"jupyter config"然后保持所有内容的正确方法别的.

This way you can tweak configuation such as password instead of token, default directory , port and so on .. Do as you want it may be a proper way to do some of the "jupyter config" in your script then keep evertything else.
