zookeeper基于docker的安装

单机模式、集群模式

单机模式：

docker-compose.yml文件

version:'3.1'
services:
    zoo1:
      image: zookeeper
      restart: always
      hostname: zoo1
      ports:
        - 2181:2181
      environment:
        ZOO_MY_ID: 1
        ZOO_SERVERS: server.1=zoo1:2888:3888

验证是否成功安装

　　以交互的方式进入容器

　　docker exec -it zookeeper_zoo1_1 /bin/bash
