3.启动多实例集群，利用docker-compose

e24-6:docker dailong$ cat docker-compose.yml 
version: '3.1'

services:
  zoo1:
    image: zookeeper
    restart: always
    hostname: zoo1

  zoo2:
    image: zookeeper
    restart: always
    hostname: zoo2
    ports:
      - 2182:2181
    environment:
      ZOO_MY_ID: 2

  zoo3:
    image: zookeeper
    restart: always
    hostname: zoo3
    ports:
