jupyter 远程访问

Jupyter 远程访问

jupyter 远程访问的工作方法是，在本地通过浏览器打开jupyter，但是代码和服务运行在远程集群中。

集群设置

首先需要确保集群中安装有python和jupyter。
在集群 /opt/intel/2019 目录下，已经安装好python3和jupyter。将其添加入环境变量中

export PATH=/opt/intel/2019/intelpython3/bin:${PATH}

随后对python路径进行检查，可以看出此时已经在调用intel python。

$ which python
/opt/intel/2019/intelpython3/bin/python

随后用以下命令对 jupyter 进行设置，设置 jupyter 登录密码。

$ jupyter notebook --generate-config

$ jupyter notebook password
Enter password:  ****
Verify password: ****

此时在个人目录下就生成了 jupyter 配置文件 jupyter_notebook_config.py。
对配置文件进行修改，增加以下设置

c.NotebookApp.ip='*' # 星号代表任意ip，这个跟mysql的权限设置一样，所以说知识是互通的
c.NotebookApp.allow_remote_access = True # 允许远程连接
c.NotebookApp.password = u'sha1:xxx' # 复制密码在此 
c.NotebookApp.open_browser = False # 不自动打开浏览器
c.NotebookApp.port = 6666 # 指定端口, 访问时使用

注意在设置端口时给定一个较大的整数，22 或 24 等常用端口时不可以的。
此时即可在命令行中启动jupyter notebook服务，会显示以下内容：

$ jupyter notebook
[W 14:01:28.051 NotebookApp] Collisions detected in /home/lilongxiang/.jupyter/jupyter_notebook_config.py and /home/lilongxiang/.jupyter/jupyter_notebook_config.json config files. /home/lilongxiang/.jupyter/jupyter_notebook_config.json has higher priority: {
      "NotebookApp": {
        "password": "'sha1:llx891209' ignored, using 'sha1:a221858aea95:923e3211599640af335a06052fcea5818f118621'"
      }
    }

本地登录

注意上面内容中，提示可以使用任意ip地址登录Notebook服务。在本地网页浏览器中，以集群IP地址代替。如集群IP为10.166.15.60，在本地浏览器中输入

https://10.166.15.60:1224/

随后即可登录集群jupyter notebook服务进行操作。
