https://github.com/jupyterhub/jupyterhub 是一套支援多用戶的網際運算伺服器, 這裡展示如何在純 IPV6 的 Ubuntu 14.04 環境下進行安裝設定.

首先假如沒有固定的 IPV4 位址, 就必須透過 IPV4/IPV6 雙支援的代理主機執行 apt-get, pip3 與 http 連結.

要讓 apt-get 使用代理主機, 必須編輯 /etc/apt/apt.conf, 並且納入下列內容:

Acquire::http::Proxy "http://username:password@your.proxy.server:3128";

接著就可以進行 Jupyterhub 執行所需的 apt-get install 安裝:

安裝 npm 與 nodejs-legacy 套件:

sudo apt-get install npm nodejs-legacy

安裝 pip3 工具:

sudo apt-get install python3-pip

安裝 jupyterhub 與 notebook 模組:

sudo pip3 --proxy http://2001:288:6004:17::17:3128 install jupyterhub

sudo pip3 --proxy http://2001:288:6004:17::17:3128 install notebook

接著為了要採 https 啟動, 需要建立認証編碼用的 crt 與 key 檔案:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout jupyterhub.key -out jupyterhub.crt

完成後就可以指定 IP 啟動:

jupyterhub --ip your_server_ip --port 443 --ssl-key jupyterhub.key --ssl-cert jupyterhub.crt

或不指定 IP 方式啟動:

jupyterhub --port 9443 --ssl-key jupyterhub.key --ssl-cert jupyterhub.crt

啟動之後則可以透過 https://your_server_ip:9443 連結, 以系統帳號登入.

接下來要讓 Jupyterhub 隨著伺服器開機時啟動, 需要建立 /etc/jupyterhub/jupyterhub_config.py 與 /etc/init.d/jupyterhub 等兩個設定檔案, 並且配置 /srv/jupyterhub 目錄作為啟動目錄, 且將 jupyterhub.key 與 jupyterhub.crt 放入 /srv/jupyterhub/ssl 目錄中.

/etc/jupyterhub/jupyterhub_config.py 檔案內容:

# jupyterhub_config.py
# jupyterhub -f /etc/jupyterhub/jupyterhub_config.py
c = get_config()

import os
pjoin = os.path.join

runtime_dir = os.path.join('/srv/jupyterhub')
ssl_dir = pjoin(runtime_dir, 'ssl')
if not os.path.exists(ssl_dir):
    os.makedirs(ssl_dir)

# https on :9443
c.JupyterHub.port = 9443
# 以 IPV6 位址綁定 Jupyterhub
c.JupyterHub.ip = '2001:288:1::8888'
c.JupyterHub.ssl_key = pjoin(ssl_dir, 'jupyterhub.key')
c.JupyterHub.ssl_cert = pjoin(ssl_dir, 'jupyterhub.crt')

# put the JjupyterHub cookie secret and state db
# in /var/run/jupyterhub
c.JupyterHub.cookie_secret_file = pjoin(runtime_dir, 'jupyterhub_cookie_secret')
c.JupyterHub.db_url = pjoin(runtime_dir, 'jupyterhub.sqlite')
# or `--db=/path/to/jupyterhub.sqlite` on the command-line

# put the log file in /var/log
c.JupyterHub.log_file = '/var/log/jupyterhub.log'

# use GitHub OAuthenticator for local users
'''
c.JupyterHub.authenticator_class = 'oauthenticator.LocalGitHubOAuthenticator'
c.GitHubOAuthenticator.oauth_callback_url = os.environ['OAUTH_CALLBACK_URL']
# create system users that don't exist yet
c.LocalAuthenticator.create_system_users = True
'''
# specify users and admin
c.Authenticator.whitelist = {'username1', 'username2'}
c.Authenticator.admin_users = {'username1', 'username2'}

# start single-user notebook servers in ~/assignments,
# with ~/assignments/Welcome.ipynb as the default landing page
# this config could also be put in
# /etc/ipython/ipython_notebook_config.py
#c.Spawner.notebook_dir = '~/tmp'
#c.Spawner.args = ['--NotebookApp.default_url=/notebooks/Welcome.ipynb']

/etc/init.d/jupyterhub 檔案內容:

設定隨機啟動步驟:

$ sudo chmod +x /etc/init.d/jupyterhub
# Create a default config to /etc/jupyterhub/jupyterhub_config.py
$ sudo jupyterhub --generate-config -f /etc/jupyterhub/jupyterhub_config.py
# Start jupyterhub
$ sudo service jupyterhub start
# Stop jupyterhub
$ sudo service jupyterhub stop
# Start jupyterhub on boot
$ sudo update-rc.d jupyterhub defaults

設定完成後, 利用 sudo /etc/init.d/jupyterhub start 進行測試, 利用 /etc/init.d/jupyterhub stop 關閉.

啟動後, 則可開啟瀏覽器連結 https://[2001:288:1::8888]:9443 , 以系統帳號登入 Jupyterhub.
