Jupyter 遠程訪問

jupyter 遠程訪問的工作方法是，在本地通過瀏覽器打開jupyter，但是代碼和服務運行在遠程集群中。

集群設置

首先需要確保集群中安裝有python和jupyter。
在集群 /opt/intel/2019 目錄下，已經安裝好python3和jupyter。將其添加入環境變量中

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

隨后對python路徑進行檢查，可以看出此時已經在調用intel python。

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

隨后用以下命令對 jupyter 進行設置，設置 jupyter 登錄密碼。

$ jupyter notebook --generate-config

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

此時在個人目錄下就生成了 jupyter 配置文件 jupyter_notebook_config.py。
對配置文件進行修改，增加以下設置

c.NotebookApp.ip='*' # 星號代表任意ip，這個跟mysql的權限設置一樣，所以說知識是互通的
c.NotebookApp.allow_remote_access = True # 允許遠程連接
c.NotebookApp.password = u'sha1:xxx' # 復制密碼在此 
c.NotebookApp.open_browser = False # 不自動打開瀏覽器
c.NotebookApp.port = 6666 # 指定端口, 訪問時使用

注意在設置端口時給定一個較大的整數，22 或 24 等常用端口時不可以的。
此時即可在命令行中啟動jupyter notebook服務，會顯示以下內容：

$ jupyter notebook

      "NotebookApp": {
        "password": "'sha1:llx891209' ignored, using 'sha1:a221858aea95:923e3211599640af335a06052fcea5818f118621'"
      }
    }

本地登錄

注意上面內容中，提示可以使用任意ip地址登錄Notebook服務。在本地網頁瀏覽器中，以集群IP地址代替。如集群IP為10.166.15.60，在本地瀏覽器中輸入

https://10.166.15.60:1224/

隨后即可登錄集群jupyter notebook服務進行操作。
