hbase集群搭建，

hbase集群搭建，

1.上传hbase安装包

 

2.解压

 

3.配置hbase集群，要修改3个文件（首先zk集群已经安装好了）

注意：要把hadoop的hdfs-site.xml和core-site.xml放到hbase/conf下

3.1修改hbase-env.sh

export JAVA_HOME=/usr/java/jdk1.7.0_55

//告诉hbase使用外部的zk

export HBASE_MANAGES_ZK=false

vim hbase-site.xml

<configuration>
		<!-- 指定hbase在HDFS上存储的路径 -->
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://ns1/hbase</value>
        </property>
		<!-- 指定hbase是分布式的 -->
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
		<!-- 指定zk的地址，多个用“,”分割 -->
        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>zookeeperServer01:2181,zookeeperServer02:2181,zookeeperServer03:2181</value>
        </property>
</configuration>

vim regionservers

zookeeperServer01#集群主机名
zookeeperServer02
zookeeperServer03

3.2拷贝hbase到其他节点

scp -r /opt/hbase-0.96.2-hadoop2/  其他节点:/opt/

配置ntp服务端

# ntp.conf(5), ntp_acc(5), ntp_auth(5), ntp_clock(5), ntp_misc(5), ntp_mon(5).

# permit the source to query or modify the service on this system.

# be tightened as well, but to do so would effect some of
# the administrative functions.

#其他节点启动ntp服务

service ntpd start

#查看ntp同步状态

#启动hbase

 

#在主节点执行

start-hbase.sh

 

#启动主节点备机（可多台）

./hbase-daemon.sh start master
