本文详细介绍HBase的安装步骤及配置方法，包括选择稳定版本、配置JAVA_HOME、HBASE_MANAGES_ZK参数、hbase-site.xml关键属性、regionservers节点设置及环境变量配置，并介绍如何启动HBase集群。

部署运行你感兴趣的模型镜像

1，前言：

hbase 是hadoop database的缩写，是一个高可靠性、高性能、面向列、可伸缩的分布式存储系统，利用HBase技术可在廉价PC Server上搭建起大规模结构化存储集群。

2，安装

2.1，hbase官网下载安装包,根据官方建议，使用stable版本

2.2，新建hbase安装目录，解压安装包到当前目录

mkdir -p /opt/hbase
chown hadoop:hadoopGroup /opt/hbase
tar -zxvf hbase-1.2.6-bin.tar.gz

2.3，配置hbase配置文件

hbase配置文件目录：/opt/hbase/hbase-1.2.6/conf

2.3.1，修改hbase-env.sh,

配置JAVA_HOME,HBASE_CLASSPATH,

这里使用hbase自带的zookeeper服务管理集群，故设置HBASE_MANAGES_ZK为true.

# The java implementation to use.  Java 1.7+ required.
export JAVA_HOME=/usr/local/java/jdk1.8.0_161

# Extra Java CLASSPATH elements.  Optional.
export HBASE_CLASSPATH=/opt/hbase/conf

...

# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=true

2.3.2,修改hbase-site.xml：

<configuration>
        <property>
                <name>hbase.rootdir</name>
                <!-- hbase存放数据目录 -->
                <value>hdfs://master:9000/hbase/hbase_db</value>
                <!-- 端口要和Hadoop的fs.defaultFS端口一致-->
        </property>
        <property>
                <name>hbase.cluster.distributed</name>
                <!-- 是否分布式部署 -->
　              <value>true</value>
        </property>
        <property>
　              <name>hbase.master</name>
　　　          <value>master:60000</value>
        </property>
        <property>
　              <name>hbase.zookeeper.quorum</name>
                <!-- list of  zookooper -->
　　　          <value>master,base0186,base0185,base0184,base0183</value>
        </property> 　　　
        <property>
                <!--zookooper配置、日志等的存储位置 -->
                <name>hbase.zookeeper.property.dataDir</name>
                <value>/opt/hbase/zookeeper</value>
        </property>
</configuration>

2.4，修改regionservers，跟hadoop配置文件相似，增加节点hostname

[hadoop@master conf]$ cat regionservers 
base0183
base0184
base0185
base0186

2.5,修改环境变量vi .bash_profile

export HBASE_HOME=/opt/hbase/hbase-1.2.6
export PATH=$JAVA_HOME/bin:$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin:$HBASE_HOME/bin

source .bash_profile

2.6,同步hbase安装文件，环境变量.bash_profile文件到各个slave节点

scp -r /opt/hbase/hbase-1.2.6  hadoop@base0186:/opt/hbase/
scp -r /opt/hbase/hbase-1.2.6  hadoop@base0185:/opt/hbase/
scp -r /opt/hbase/hbase-1.2.6  hadoop@base0184:/opt/hbase/
scp -r /opt/hbase/hbase-1.2.6  hadoop@base0183:/opt/hbase/

2.7，启动hbase

start-hbase.sh

[hadoop@master conf]$ start-hbase.sh
