一、概要
2、角色
a、zk集群
10.10.20.64:2181
10.10.40.212:2181
10.10.102.207:2181
b、hbase
10.10.40.212 HMaster
10.10.20.64 HMaster
10.10.10.114 HRegionServer
10.10.40.169 HRegionServer
10.10.30.174 HRegionServer
2、安装zk集群（所有zk节点都操作）
1、安装
yum -y install zookeeper zookeeper-server
b、配置
vim /etc/zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/lib/zookeeper
clientPort=2181
maxClientCnxns=0
server.1=10.10.20.64:2888:3888
server.2=10.10.40.212:2888:3888
server.3=10.10.102.207:2888:3888
autopurge.snapRetainCount=3
autopurge.purgeInterval=1
mkdir -p /data/lib/zookeeper #建zk的dir目录
echo 1 >/data/lib/zookeeper/myid #10.10.20.64上操作
echo 2 >/data/lib/zookeeper/myid #10.10.40.212上操作
echo 3 >/data/lib/zookeeper/myid #10.10.102.207上操作
c、启动服务
/etc/init.d/zookeeper-server start
3、安装配置hbase集群
a、安装
yum -y install hbase hbase-master #HMaster节点操作
yum -y install hbase hbase-regionserver #HRegionServer节点操作
b、配置（所有base节点操作）
vim /etc/hbase/conf/hbase-site.xml
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.zookeeper.quorum</name>
<value>10.10.20.64:2181,10.10.40.212:2181,10.10.102.207:2181</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>

</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
<description>集群的模式，分布式还是单机模式，如果设置成false的话，HBase进程和Zookeeper进程在同一个JVM进程
</description>
</property>
</configuration>
echo "export HBASE_MANAGES_ZK=false" >>/etc/hbase/conf/hbase-env.sh
#设置hbase使用独立的zk集群
vim /etc/hbase/conf/regionservers
ip-10-10-30-174.ec2.internal
ip-10-10-10-114.ec2.internal
ip-10-10-40-169.ec2.internal
#添加HRegionServer的主机名到regionservers，我没有在/etc/hosts下做主机名的映射，直接用了ec2的默认主机名
c、启动服务
/etc/init.d/hbase-master start #HMaster节点操作
/etc/init.d/hbase-regionserver start #HRegionServer节点操作
4、验证
a、验证基本功能
[root@ip-10-10-20-64 ~]# hbase shell

b、验证HA功能
1、hbase默认的web管理端口是60010，两个HMaster谁先启动谁就是主active节点，10.10.40.212先启动，10.10.20.64后启动，web截图如下：

wKiom1kSy5az5p8nAAEheuczSu0415.png-wh_50
2、停止10.10.40.212的HMaster进程，查看10.10.20.64是否会提升为master
/etc/init.d/hbase-master stop
