Jupyter_notebook 搭建服務及更換主題

Jupyter notebook

準備工作

1. 一臺雲服務器(我用的是騰訊服務器，centos7)
2. 服務器已安裝 python3
3. 有一定python基礎
4. 熱愛學習的心和不怕艱辛的熱忱

安裝jupyter-notebook

1. pip3 install jupyter notebook
2. 生成配置jupyter notebook --generate-config
3. 配置一般在 ~/.jupyter/jupyter_notebook_config.py 中
4. 設置密碼及設置工作目錄

   ## The directory to use for notebooks and kernels.
   c.NotebookApp.notebook_dir = '/root/jupyter_notebooks'
   
   ## Whether to open in a browser after starting. The specific browser used is
   ...
   #  To generate, type in a python/IPython shell:
   #
   #    from notebook.auth import passwd; passwd()
   #
   #  The string should be of the form type:salt:hashed-password.
   c.NotebookApp.password = 'sha1:ff737af759e0:5fdc6a7df25b9af4912204ced9ca309336defe8f'
   

   1. 修改密碼，使用python生成密碼的密鑰

      	from notebook.auth import passwd; print(passwd("123456"))
      

   2. 生成密碼後，替換掉那一串字符
5. 啓動服務

   # 正常啓動(前臺運行)
   $ jupyte-notebook --config ~/.jupyter/jupyter_notebook_config.py
   # 後臺運行
   $ mkdir jupyter_notebooks
   $ nohup jupyter-notebook --config .jupyter/jupyter_notebook_config.py 1>jupyter_notebooks/jupyter.log 2>&1 &
   

6. 測試是否成功

   $wget 127.0.0.1:8888
   --2020-01-11 10:49:58--  http://127.0.0.1:8888/
   Connecting to 127.0.0.1:8888... connected.

   2020-01-11 10:49:58 (208 MB/s) - ‘index.html’ saved [9113/9113]
   

7. 設置防火牆通過8888端口
   iptables -A INPUT -p tcp -m tcp --dport 8080 -j accept
   or
   firewall-cmd --permanent --add-port=8888/tcp
firewall-cmd --reload
8. 打開瀏覽器，訪問http://ip:8888

常見問題

• 密碼修改不成功

1. ./jupyter 下面還有一個 jupyter_notebook_config.json，將其刪除，然後修改配置文件，最後重啓服務就可以了

• 瀏覽器打開沒反應怎麼辦

1. 先看下電腦和雲服務器的網絡是否通暢 ping ip
2. 再看下雲服務器的jupyter進程是否還在 ps -aux | grep jupyter 和 lsof -i:8888
3. 看下端口是否能telnet telnet ip 8888 電腦沒有telnet怎麼辦
4. 看下防火牆是否已經通過 8888 端口，雲服務除linux防火牆外，雲服務商還有一套防火牆，可以自己詢問相應的客服諮詢

Jupyter notebook 修改字體，修改顏色，修改主題

1. 感謝大神做的notebook主題，查看GitHub
2. 安裝jupyter themes
   pip3 install --upgrade jupyterthemes’
3. 使用命令行設置相應配置
   1. 查看支持的主題

      $ jt -l
      Available Themes:   chesterish   grade3
      gruvboxd
      gruvboxl
      monokai
      oceans16
      onedork
      solarizedd
      solarizedl
      	```
      

   2. 配置 主題爲 oceans16， 字體爲 fira，字體大小爲 13

      	jt -t oceans16 -f fira -fs 13
      

   3. 具體規則
      
4. 參考文章： https://blog.csdn.net/qq_30565883/article/details/79444750
5. 所有字體
6. 注意事項：直接修改字體和字體大小，是不會生效的
7. 清除所有主題，恢復默認 jt -r
