Jupyter_notebook 搭建服务及更换主题

Jupyter notebook

准备工作

1. 一台云服务器(我用的是腾讯服务器，centos7)
2. 服务器已安装 python3
3. 有一定python基础
4. 热爱学习的心和不怕艰辛的热忱

安装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. 设置密码及设置工作目录

   ## 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. 修改密码，使用python生成密码的密钥

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

   2. 生成密码后，替换掉那一串字符
5. 启动服务

   # 正常启动(前台运行)
   $ jupyte-notebook --config ~/.jupyter/jupyter_notebook_config.py
   # 后台运行
   $ mkdir jupyter_notebooks
   $ nohup jupyter-notebook --config .jupyter/jupyter_notebook_config.py 1>jupyter_notebooks/jupyter.log 2>&1 &
   

6. 测试是否成功

   $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.

7. 设置防火墙通过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. 打开浏览器，访问http://ip:8888

常见问题

• 密码修改不成功

1. ./jupyter 下面还有一个 jupyter_notebook_config.json，将其删除，然后修改配置文件，最后重启服务就可以了

• 浏览器打开没反应怎么办

1. 先看下电脑和云服务器的网络是否通畅 ping ip
2. 再看下云服务器的jupyter进程是否还在 ps -aux | grep jupyter 和 lsof -i:8888
3. 看下端口是否能telnet telnet ip 8888 电脑没有telnet怎么办
4. 看下防火墙是否已经通过 8888 端口，云服务除linux防火墙外，云服务商还有一套防火墙，可以自己询问相应的客服咨询

Jupyter notebook 修改字体，修改颜色，修改主题

1. 感谢大神做的notebook主题，查看GitHub
2. 安装jupyter themes
   pip3 install --upgrade jupyterthemes’
3. 使用命令行设置相应配置
   1. 查看支持的主题

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

   2. 配置 主题为 oceans16， 字体为 fira，字体大小为 13

      	jt -t oceans16 -f fira -fs 13
      

   3. 具体规则
      
4. 参考文章： https://blog.csdn.net/qq_30565883/article/details/79444750
5. 所有字体
6. 注意事项：直接修改字体和字体大小，是不会生效的
7. 清除所有主题，恢复默认 jt -r
