關於jupyter 的設定

jupyter 設定

生成登入密碼

可以進入jupyter ，或者Ipython，輸入以下程式碼

In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password:#如'passwd' 輸入自己的密碼
Verify password:#再次輸入'passwd'
Out[2]: 'sha1:9ffede0825894254b2e042ea597d7711aad'

生成jupyter 的配置檔案

$ jupyter notebook --generate-config
 

編輯jupyter 配置檔案

$ vim  ~/.jupyter/jupyter_notebook_config.py

在裡面新增如下資訊

# Set options for certfile, ip, password, and toggle off
# browser auto-opening
#c.NotebookApp.certfile = u'/absolute/path/to/your/certificate/mycert.pem'
#c.NotebookApp.keyfile = u'/absolute/path/to/your/certificate/mykey.key'
# Set ip to '*' to bind on all interfaces (ips) for the public server
 

#上面的感覺沒有用，註釋了
c.NotebookApp.ip = '*'


c.NotebookApp.password = u'sha1:9ffede0825894e042ea597d771089edf11aad'

#發現更方便的方法，直接用上面的明文會簡單，當然可能不安全
#c.NotebookApp.password = u'sha1:bcd259ccf...<就是剛剛上面的密碼，替換冒號裡面的值>'
c.NotebookApp.open_browser = False
# It is a good idea to set a known, fixed port for server access，設定埠
 

c.NotebookApp.port = 8888

上週停電，伺服器現在重啟，以後密碼總是不對，按照配置檔案中的修改也不行，最後查詢文件，又用了另外一種方法：

[[email protected] ~]$ jupyter notebook password  
Enter password: "mima"
Verify password: "mima"
[NotebookPasswordApp] Wrote hashed password to /home/centos/.jupyter/jupyter_notebook_config.json
[[email protected] ~]$  jupyter notebook
[W 09:56:03.592 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.

[I 09:56:03.663 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).

最後進入網頁，輸入在上面的配置好的密碼 :’mima’，就可以進入了

配置防火牆埠

直接在伺服器執行命令

$ jupyter notebook  

我用的是CentOS7.3，不過我在客戶端連線不反應，一查是防火牆的問題

於是就在防火牆新增 8888 埠

#新增8888埠
$ firewall-cmd --zone=public --add-port=8888/tcp --permanent
#重啟防火牆
$ systemctl restart firewalld.service

好的，在輸入啟動，

$ jupyter notebook  
[[email protected] ~]$  jupyter notebook

不過看啟動文件是不是8888，如果被佔用就是8889，

檢視那個程序在佔用這個埠，沒用就刪除了，

以前後臺啟動了jupyter ,所以刪除了，

kill -9  18997

這下就好了

後面再等了，讓輸入密碼，我一直輸入 ‘sha1:9ffede0825894254b2e042ea597d771089e11aad’
不過一直報錯，所以我估計是’sha1：’ 不需要輸入，只需要冒號後面的。

最後沒有問題後，讓這個Server一直後臺執行，即使關了ssh 也不用停服務

$ nohup jupyter notebook &

#項查詢日誌，可以輸入
$ cat nohup.out
