一，部署环境及安装包
系统：Ubuntu 18.04.5 LTS
1.系统自带的python或python3.7
2.Python安装 包安装和管理工具pip
3.pip安装 代理/抓包工具Mitmproxy
4.pip安装 传输和存储数据工具protobuf
二，操作：
查看软件版本
root@root1:~# python3 --version
Python 3.6.9
root@root1:~# pip --version
Command 'pip' not found, but can be installed with:apt install python-pip
root@root1:~# mitmproxy --version
Command 'mitmproxy' not found, but can be installed with:apt install mitmproxy
1.Python3.6.9版（先用这一版，不行在用3.7）
1）安装pip
su root #切换到root用户
sudo apt update
sudo apt install python3-pip
结果：
root@root1:~# pip3 --version
pip 9.0.1 from /usr/lib/python3/dist-packages (python 3.6)
2）安装Mitmproxy
pip3 install mitmproxy
