使用python自动创建基于systeamd的守护配置

手动配置systeamd配置文件始终是一件麻烦的事情

每次手动配置都要复制一份之前的配置，再手动修改，难免会改出问题。。。所以撸了个生成脚本，只需要按步骤填写对应的值就好了，减少出错的可能性。

将下面的python代码保存为create_systeamd.py

import os
import time

After=network.target

[Service]
Type={type}
ExecStart={exec_start}

User={user}
Group={group}
{other_data}

[Install]
WantedBy=multi-user.target

运行python3 create_systeamd.py, 按照提示输入内容就行啦!
