Hbase集群搭建

  • 1、上传hbase安装包

  • 2、解压

      tar -zxvf hbase-0.96.2-hadoop2-bin.tar.gz -C /softWare/

  • 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
	cd /softWare/hadoop-2.2.0/etc/hadoop
  	cp hdfs-site.xml /softWare/hbase-0.96.2-hadoop2/conf/
  	cp core-site.xml /softWare/hbase-0.96.2-hadoop2/conf/

    • 3.1修改hbase-env.sh

      vim /softWare/hbase-0.96.2-hadoop2/conf/hbase-env.sh

export JAVA_HOME=/softWare/jdk1.7.0_80
//告诉hbase使用外部的zk 
export HBASE_MANAGES_ZK=false

    • 3.2修改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>hadoop04:2181,hadoop05:2181,hadoop06:2181</value>
  	</property>
  </configuration>

    • 3.3修改regionservers

      hadoop03
hadoop04
hadoop05
hadoop06

    • 3.4拷贝hbase到其他节点

        scp -r /softWare/hbase-0.96.2-hadoop2/ hadoop02:/softWare/
  scp -r /softWare/hbase-0.96.2-hadoop2/ hadoop03:/softWare/
  scp -r /softWare/hbase-0.96.2-hadoop2/ hadoop04:/softWare/
  scp -r /softWare/hbase-0.96.2-hadoop2/ hadoop05:/softWare/
  scp -r /softWare/hbase-0.96.2-hadoop2/ hadoop06:/softWare/

  • 4、将配置好的HBase拷贝到每一个节点并同步时间。

  • 5、启动所有的hbase

    分别启动zk
  ./zkServer.sh start
启动hbase集群
  ./start-dfs.sh
启动hbase，在主节点上运行：
  ./start-hbase.sh

  • 6、通过浏览器访问hdase管理页面

      192.168.2.101:60010

  • 7、为保证集群的可靠性，要启动多个HMaster

      hbase-daemon.sh start master

  • 8、使用操作

    • hbase shell

       [root@hadoop01 bin]# hbase shell
 2018-07-29 01:32:53,499 INFO  [main] Configuration.deprecation: hadoop.native.lib is deprecated.
