大数据 Docker Zookeeper 集群环境搭建
前言
为搭建hbase集群环境，预先搭建Zookeeper环境，废话不多说，直接盘他。此文基础Docker及Docker-compose技术，如何搭建Docker及使用请点击这里
Zookeeper官方网站
搭建版本: 3.8.4
JDK: openjdk8
系统环境: centos7.9.2009
基础环境
系统镜像环境：java:openjdk8-centos.base-7.9.2009
docker pull registry.cn-hangzhou.aliyuncs.com/snake-group/java:openjdk8-centos.base-7.9.2009
此镜像是在
centos7.9.2009基础上安装了一系统工具包的二次镜像包：iputils nc less libcurl zip unzip tar net-tools iptutils-ping sysvinit-tools iptables wget telnet ntp kde-l10n-Chinese,时区为Asia/Shanghai，系统编码为zh_CN.UTF-8,Java环境为openjdk8
搭建软件准备
