这篇文章将详细的讲述一下HBase的安装。

下载安装包

进入CDH Archive页面 http://archive.cloudera.com/cdh5/cdh/5/

选择需要安装的HBase版本，这次安装选择的是hbase-1.2.0-cdh5.7.0

下载链接 http://archive.cloudera.com/cdh5/cdh/5/hbase-1.2.0-cdh5.7.0.tar.gz

1 2	cd /usr/local/hbase wget http://archive.cloudera.com/cdh5/cdh/5/hbase-1.2.0-cdh5.7.0.tar.gz

解压安装包

1	tar -zxvf hbase-1.2.0-cdh5.7.0.tar.gz

添加环境变量

1	vi ~/.bash_profile

在文件里面加入以下内容

1	export HBASE_HOME=/usr/local/hbase/hbase-1.2.0-cdh5.7.0/

然后执行source命令使配置文件生效

source ~/.bash_profile

echo $HBASE_HOME
/usr/local/hbase/hbase-1.2.0-cdh5.7.0/

修改配置文件

进入到$HBASE_HOME目录，并修改conf/hbase-env.sh配置文件

1 2	cd $HBASE_HOME vi conf/hbase-env.sh

修改JAVA_HOME参数，指定JAVA_HOME的位置

1	export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

修改HBASE_MANAGES_ZK参数为false，不让HBase管理自己的Zookeeper实例，因为我们需要自己安装Zookeeper

1	export HBASE_MANAGES_ZK=false

修改hbase-site.xml文件

<configuration>
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://localhost:8020/hbase</value>
        </property>

        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>localhost:2181</value>
        </property>
</configuration>

regionserver文件，如果是单机伪分布环境，则可以不用改，默认为localhost

启动zookeeper

在启动HBase之前，我们需要先启动zookeeper

cd $ZK_HOME
sbin/zkServer.sh start

JMX enabled by default
Using config: /usr/local/zookeeper/zookeeper-3.4.5-cdh5.7.0/sbin/../conf/zoo.cfg
Starting zookeeper ... STARTED

jps

zookeeper实例已经启动

启动HBase

1 2	cd $HBASE_HOME bin/start-hbase.sh

starting master, logging to /usr/local/hbase/hbase-1.2.0-cdh5.7.0//logs/hbase-simon-master-localhost.out
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
starting regionserver, logging to /usr/local/hbase/hbase-1.2.0-cdh5.7.0//logs/hbase-simon-1-regionserver-localhost.out

我们可以看到starting master和starting regionserver

jps

50607 HMaster
50703 HRegionServer

说明HBase已经成功的启动了。

cd $HADOOP_HOME

bin/hadoop fs -ls /

可以看到前面设置的hdfs://localhost:8020/hbase已经被成功创建了。

通过Web UI查看HBASE信息

在浏览器地址栏输入 http://localhost:60010

查看状态

创建表member，包含info和address两个列蔟

hbase(main):003:0> create 'member', 'info', 'address'
0 row(s) in 2.3700 seconds

=> Hbase::Table - member

查看数据库表列表

hbase(main):004:0> list

member
1 row(s) in 0.0380 seconds

=> ["member"]

查看member表信息

hbase(main):005:0> describe 'member'
Table member is ENABLED

我们再次查看HBase Web UI

发现在Tables标题栏里面已经多了一条记录了。

清空数据表
