JupyterNotebook安装

准备环境

python

准备python3.8

# cd /usr/local/src
# mkdir /usr/local/pythin38
# tar zxvf Python-3.8.13.tgz 
# 安装依赖
# yum install -y gcc patch libffi-devel python-devel  zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

编译安装

# cd Python-3.8.13
# ./configure --prefix=/usr/local/pythin38/
# make -j
# make install
# ls /usr/local/pythin38/

配置系统环境变量

# vim  /etc/profile
# 最后一行添加
……
PATH=$PATH:/usr/local/pythin38/bin
……
# python3 --version
Python 3.8.13

或者添加软连接

# ln -s /usr/local/pythin38/bin/python3 /usr/bin/python3
# ln -s /usr/local/pythin38/bin/pip3 /usr/bin/pip3

安装jupterNotebook

# pip3 install jupyter -i https://pypi.tuna.tsinghua.edu.cn/simple
# 查看是否成功 官方不建议以root用户运行 下面有登录的token
# jupyter notebook --ip=192.168.10.169 --no-browser --allow-root
[I 15:35:53.478 NotebookApp] Serving notebooks from local directory: /usr/local/src/Python-3.8.13
[I 15:35:53.478 NotebookApp] Jupyter Notebook 6.4.11 is running at:
[I 15:35:53.478 NotebookApp] http://192.168.10.169:8888/?token=0611072ca9ddac547ec039a6d78ddbd3bb8e870da16b0d09

[I 15:35:53.478 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
[C 15:35:53.481 NotebookApp] 
    
    To access the notebook, open this file in a browser:
        file:///root/.local/share/jupyter/runtime/nbserver-14102-open.html
    Or copy and paste one of these URLs:
        http://192.168.10.169:8888/?token=0611072ca9ddac547ec039a6d78ddbd3bb8e870da16b0d09

# 也可以修改密码，直接密码登录
# jupyter notebook password

# 访问url进入
http://192.168.10.169:8888/

配置

默认情况下，在哪个目录启动jupterNotebook 当前的工作目录就是哪个目录，可以设置指定目录

生成配置目录

# jupyter notebook --generate-config
Writing default config to: /root/.jupyter/jupyter_notebook_config.py

编辑配置文件，修改目录完成后工作目录就是修改的目录了

在/opt/jupyternotebook创建文件 jupyternotebook页面就会有相应的目录
```
# vim  /root/.jupyter/jupyter_notebook_config.py
……
c.NotebookApp.notebook_dir = '/opt/jupyternotebook'
……
```

使用

新建项目 python3环境
重命名项目

需要先停止项目然后重命名
项目运行

如图，中括号中的数字表示当前运行的第几个程序如果是*号代表正在运行
检查点，可以手动保存创建检查点，用于出错的时候回退如下图保存和回退

自动保存不会创建记录点只有手动保存才会
停止

每个notebook都对应一个kernel内核停止notebook就是停止一个内核

主题

安装主题库

# pip3 install jupyterthemes -i https://pypi.tuna.tsinghua.edu.cn/simple

查看主题

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

设置主题

# jt -t chesterish

# 恢复默认主题
# jt -r

设置完成后重启

# jupyter notebook --ip=192.168.10.169 --no-browser --allow-root

插件

安装插件库

# pip3 install jupyter_nbextensions_configurator -i https://pypi.tuna.tsinghua.edu.cn/simple

# 启用
# jupyter nbextensions_configurator enable --user

启动

会显示一个配置器还需要安装插件

# jupyter notebook --ip=192.168.10.169 --no-browser --allow-root

安装第三方插件

# pip3 install jupyter_contrib_nbextensions -i https://pypi.tuna.tsinghua.edu.cn/simple
# jupyter contrib nbextension install --user

至此插件就可用了

安装java内核

在官方下载java内核

https://github.com/jupyter/jupyter/wiki/Jupyter-kernels

目前最低支持到java9

下载内核包：https://github.com/SpencerPark/IJava/releases/ijava-1.3.0.zip

解压安装

# unzip ijava-1.3.0.zip 
# python3 install.py --sys-prefix
install.py:164: DeprecationWarning: replace is ignored. Installing a kernelspec always replaces an existing installation
  install_dest = KernelSpecManager().install_kernel_spec(
Installed java kernel into "/usr/local/pythin38/share/jupyter/kernels/java"

# 查看是否安装成功 有没有java内核
# jupyter kernelspec list
Available kernels:
  java       /usr/local/pythin38/share/jupyter/kernels/java
  python3    /usr/local/pythin38/share/jupyter/kernels/python3

重启jupyter

# jupyter notebook --ip=192.168.10.169 --no-browser --allow-root

创建的时候就会有java内核了

tips

使用？查看对象的注释或者文档
```
import time
time.sleep?
```
执行shell命令

在命令前加上叹号(!) 就可以直接执行shell命令还可以将返回直接赋值给变量
```
!ls ./

#赋值给变量
file = !ls
print(file)
```
单元格的最后一行值会被默认输出，如果不想输出需要在最后一行添加分号;
```
a = 18
a;
```
