[me@PC ~]$

続いて、Jupyter notebookの設定をします。 その前に、認証用のパスワードを作成します。

[me@PC ~]$ ipython3
Python 3.6.0 (default, Jan  4 2017, 01:52:52)
Type "copyright", "credits" or "license" for more information.

IPython 5.1.0 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object', use 'object??' for extra details.

In [1]: from notebook.auth import passwd

In [2]: passwd()
Enter password:
Verify password:
Out[2]: 'sha1:68a878e770dd:f3a15262d7a59d744d4eca4284d3489821e30e51'

In [3]: exit()
[me@PC ~]$

Out[2]に出力された'sha1:...'の文字列がパスワードがハッシュ化されたものです。これを以下の設定ファイルに書きます。

[me@PC ~]$ jupyter notebook --generate-config
Writing default config to: /home/me/.jupyter/jupyter_notebook_config.py
[me@PC ~]$ vi .jupyter/jupyter_notebook_config.py

# 全てのIPアドレスから着信を許可する
#c.NotebookApp.ip = 'localhost'
c.NotebookApp.ip = '*'

# ノートブックのデフォルトパスを指定する
#c.NotebookApp.notebook_dir = ''
c.NotebookApp.notebook_dir = '/home/me/jupyternotebook'

# 起動時にブラウザを開く設定をOFFにする（GUI環境でないのでWARNING出ないように）
#c.NotebookApp.open_browser = True
c.NotebookApp.open_browser = False

# パスワード（上記で吐き出したハッシュをコピー）
#c.NotebookApp.password = ''
c.NotebookApp.password = 'sha1:68a878e770dd:f3a15262d7a59d744d4eca4284d3489821e30e51'

さて起動してくれるでしょうか！？ notebook用のディレクトリを作成し、いざ起動！

[me@PC ~]$ mkdir jupyternotebook
[me@PC ~]$ jupyter notebook
[I 02:35:59.512 NotebookApp] Writing notebook server cookie secret to /run/user/1001/jupyter/notebook_cookie_secret

ブラウザを起動して、http://localhost:18888 へGO!

ログイン画面が出ました！

ディレクトリツリーが表示されました！

New -> Python3 と選ぶと・・・新規ノートブックが開きます。

ためしに、1+2と打って、Shift+Enter！ 計算結果が 3 と出ました。 動作確認OKです。 [次は、ライブラリのインストール](/2017/01/makejupyter24.html)
