前提条件：2核8g，已安装dockerCompose

1.准备好dockerCompose.yaml文件

version: '2.2'
services:

    driver: bridge

2.运行yaml文件：docker-compose up -d     

3查看启动结果：docker-compose ps

4.注意：容器挂在卷的位置可以根据自己的实际情况选择合适的位置

        4.1 skywalking-oap容器挂载卷第一次启动时是无需设置的，等到容器全部启动后进入容器copy这个文件夹到一个位置然后删除全部容器，添加skwalking-oap容器挂在卷以便于后续更改数据过期、告警等规则
