Local virtual machine initialization script

The latest period of time , Virtual machine initialization is required , So install some services as needed , Organize a script , Share with you ,

Some of the environment configurations may not be suitable , Manual modification is required

#!/bin/bash
# Suitable for local virtual machine environment 

# Process detection . If the host has this service, the installation function will not be called
