遠程remote 01——Ubuntu由ssh遠程訪問jupyter notebook

Ubuntu由ssh遠程訪問jupyter notebook

1. Jupyter-notebook configuration file

jupyter notebook --generate-config

Note: 會有以下配置文件生成的提醒:
Writing default config to: /home/computer_name/.jupyter/jupyter_notebook_config.

2. Generate password

使用python,遠程電腦裏有ipython可以直接輸入ipython

$ python
from notebook.auth import passwd
passwd()
# 輸入完後會出現以下輸入密碼,該密碼爲遠程登錄jupyter密碼
Enter password:******
Verify password:******
# 下面爲配置文件的密文
輸出爲: 'sha1:cd723d3e4b0afg34hasrsf65yr453t32hj456d2627fb'

3. Modify configuration file

用vim或者gedit, 修改第一步生成的配置文件:

vim ~/.jupyter/jupyter_notebook_config.py

修改如下:

# *號表示任何的IP地址都可以訪問
c.NotebookApp.ip= '*'                                                             #204 line
# 前面第一步生成的密文
c.NotebookApp.password = u'sha1:cd723d3e4b0afg34hasrsf65yr453t32hj456d2627fb'     #267 line
# 表示在打開jupyter的時候不會自動打開遠程的瀏覽器
c.NotebookApp.open_browser = False                                                #276 line
# 這裏可以任意定義一個端口進行連接需要
c.NotebookApp.port = 9999                                                         #288 line

以上行數爲修改之前的行數。
Note: 這裏打開以後所有的配置是被註釋掉的, 所以先複製上面的配置, 然後在另起一行進行修改.如下:

# c.NotebookApp.ip= 'hostname' 
c.NotebookApp.ip= '*' 

4. Launch jupyter-notebook

對不同python環境下的jupyter不熟悉的可以查看我另外一篇的最後一節 Link
1.在遠程電腦上的terminal中輸入jupyter-notebook, 然後會出現一個警告, 這個沒關係, 記住之前設置密文的密碼就行.

[W 17:28:47.794 NotebookApp] WARNING: The notebook server is listening on all IP addresses and not using encryption. This is not recommended.

2.root 用戶使用

jupyter notebook --allow-root

3.後臺執行

nohup jupyter notebook --allow-root &

5. Remote login

在自己的電腦上, 可以直接從本地瀏覽器直接訪問http://address_of_remote:8888就可以看到jupyter的登陸界面.
比如: 遠程電腦的ip地址是: 127.0.0.1
你設置的端口號爲: 9999
那麼瀏覽器輸入: 127.0.0.1:9999 即可.
可以看到如下界面, 然後輸入第一步設置的密碼即可登錄到遠程電腦的home界面.

之後只需要遠程使用輕薄本, 來使用高性能臺式機爲自己的程序進行測試.

6. Problem

以上設置，測試過沒有問題的，但是最近遠程電腦重裝了以後，按照以上步驟出現的一些錯誤

~$ jupyter-notebook

Traceback (most recent call last):
  File "/home/zzl/anaconda3/lib/python3.6/site-packages/traitlets/traitlets.py", line 528, in get

    value = self._validate(obj, dynamic_default())
  File "/home/zzl/anaconda3/lib/python3.6/site-packages/notebook/notebookapp.py", line 867, in _default_allow_remote
    for info in socket.getaddrinfo(self.ip, self.port, 0, socket.SOCK_STREAM):

    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -5] No address associated with hostname

可以看到最後錯誤顯示是hostname有問題，也就是這個這個出了問題：

# c.NotebookApp.ip= 'hostname' 
c.NotebookApp.ip= '*' 

原來的給任意的ip地址'*'不合適，這裏修改爲遠程電腦的ip地址。

c.NotebookApp.ip= 'your_remote_ip'
