HBase安装模式有三种：单机模式、分布式（伪分布式和完全分布式）。本教程介绍了HBase的完全分布式模式安装配置的过程，分布式模式均需要依赖于HDFS。
- 基础环境
- 安装配置
[一]、环境说明
- JDK1.6+
- Hadoop 2.2.0
- CentOS 6.0
- HBase-0.98.0-hadoop2
Hadoop集群机器对应于HBase用途如下：
| hostname | IP | Hadoop用途 | HBase用途 |
| Master.Hadoop | 192.168.6.77 | NameNode/ResouceManager | Master |
| Slave5.Hadoop | 192.168.8.205 | DataNode/NodeManager | RegionServer |
| Slave6.Hadoop | 192.168.8.206 | DataNode/NodeManager | RegionServer |
| Slave7.Hadoop | 192.168.8.207 | DataNode/NodeManager | RegionServer |
有关hadoop2的集群安装配置参考：http://www.micmiu.com/bigdata/hadoop/hadoop2x-cluster-setup/
[二]、安装配置
1、下载发布包
到HBase官方下载最新的版本 hbase-0.98.0-hadoop2-bin.tar.gz （支持hadoop2）为例：
|
1 2 3 |
$ tar xfz hbase-0.98.0-hadoop2-bin.tar.gz $ cd hbase-0.98.0-hadoop2 $ ln -s hbase-0.98.0-hadoop2 hbase |
注意：由于 HBase 依赖 Hadoop，在分布式模式下，Hadoop版本必须和HBase下的版本一致。用你运行的分布式Hadoop版本jar文件替换HBase lib目录下的Hadoop jar文件，以避免版本不匹配问题，也可以根据情况自己编译发布包。
2、配置系统环境
|
1 2 3 |
#HBase micmiu.com export HBASE_HOME="/usr/local/share/hbase" export PATH=$HBASE_HOME/bin:$PATH |
3、配置HBase参数
修改配置文件：<HBASE_HOME>/conf/hbase-env.sh
export JAVA_HOME = /usr/lib/jvm/java-1.6.0-openjdk.x86_64
修改配置文件：<HBASE_HOME>/conf/hbase-site.xml
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
<property> <name>hbase.rootdir</name> <!-- 和hdfs中配置的fs.defaultFS一致 by micmiu.com--> <value>hdfs://Master.Hadoop:9000/hbase</value> </property> <property> <name>hbase.cluster.distributed</name> <value>true</value> </property> <property> <name>hbase.zookeeper.quorum</name> <!-- 设置zk集群的主机，建议奇数 by micmiu.com--> <value>Slave5.Hadoop,Slave6.Hadoop,Slave7.Hadoop</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/home/hadoop/data/zookeeper</value> </property> |
修改配置文件：<HBASE_HOME>/conf/regionservers
|
1 2 3 |
Slave5.Hadoop Slave6.Hadoop Slave7.Hadoop |
注意：在HBase集群的所有机器上（一台Master：Master.Hadoop ,三台RS：Slave5.Hadoop,Slave6.Hadoop,Slave7.Hadoop 共4台设备）都需要执行上面的所有安装配置过程。
4、演示
启动HBase之前确保HDFS已经启动，和单机模式的演示过程基本一致。
4.1、启动HBase：
在Master机器 Master.Hadoop( 192.168.6.77) 上执行启动脚本：
|
1 2 3 4 5 6 |
[hadoop@Master ~]$ start-hbase.sh Master.Hadoop: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hadoop-zookeeper-Slave7.Hadoop.out Slave5.Hadoop: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hadoop-zookeeper-Slave5.Hadoop.out Slave6.Hadoop: starting zookeeper, logging to /usr/local/hbase/bin/../logs/hbase-hadoop-zookeeper-Slave6.Hadoop.out starting master, logging to /usr/local/hbase/logs/hbase-hadoop-master-Master.Hadoop.out localhost: starting regionserver, logging to /usr/local/hbase/bin/../logs/hbase-hadoop-regionserver-Master.Hadoop.out |
- 打开 http://Master.Hadoop(192.168.6.77):60010 主界面，可以查看Master运行状态。
- 打开 http://SlaveX.Hadoop(192.168.8.20x):60030 主界面，可以查看RegionServer运行状态
4.2、shell演示 建表、插入数据、查询数据、删除表

4.3、停止HBase：stop-hbase.sh
|
1 2 3 4 5 |
[hadoop@Master ~]$ stop-hbase.sh stopping hbase............... Slave7.Hadoop: stopping zookeeper. Slave5.Hadoop: stopping zookeeper. Slave6.Hadoop: stopping zookeeper. |
到此完全分布式模式的安装配置的介绍结束。
