HBase集群安装部署（完全分布式）（网上下载huangxin修改版）(3)

复制Master中的/etc/profile到Slave01和Slave02,Slave03中，在Slave01和Slave02,Slave03上执行source /etc/profile,让文件立即生效 1.4 启动集群

? 首先启动hadoop（在m1上start-all.sh），

? 然后启动zookeeper集群（分别在三台机器上zkServer.sh start;可以使用zkServer.sh status查看zk的状态）。

? 最后在Master上启动hbase集群（start-hbase.sh）。

HBase Shell操作（增删改查）

说明：

hbase提供了一个shell的终端给用户交互
