3.Hbase安装

1.系统版本信息

OS:Debian-8.2
JDK:1.8.0_181
Hadoop-2.8.4
Zookeeper-3.4.10
Hbase：1.3.1

主机信息

192.168.74.131  master
192.168.74.133  slave1
192.168.74.134  slave2
192.168.74.135  slave3

2.前提条件

• A:安装好jdk并配置好环境变量
• B:安装好Hadoop并能够跑通example下的wordcout
• C:安装好zookeeper，并能够跑通

3.首先在master上安装hbase

A:下载hbase1.4.6

    使用wget下载镜像站下的某个版本，如wget http://mirror.bit.edu.cn/apache/hbase/1.4.6/hbase-1.4.6-bin.tar.gz

    http://mirror.bit.edu.cn/apache/hbase/

B:解压并移动hbase到指定文件夹下

tar zxvf hbase-1.4.6-bin.tar.gz
mv hbase-1.4.6 /home/hadoop/opt/

C:配置环境变量

sudo vim /etc/profile
#Set Hbase Path
export HBASE_HOME=/home/hadoop/opt/hbase-1.4.6
export PATH=$PATH:$HBASE_HOME/bin

##立即生效
source /etc/profile

D:配置Hbase配置文件hbase-site.xml,注意的是这个配置文件是与hadoop，zookeeper密切相关的，所以前提是已经配置好hadoop和zookeeper

cd /home/hadoop/opt/hbase-1.4.6/conf

vim hbase-site.xml

<configuration>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://master:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>master,slave1,slave2,slave3</value>
    </property>
    <property>
        <name>hbase.zookeeper.property.dataDir</name>
        <value>/home/hadoop/opt/zookeeper-3.4.10/data</value>
    </property>
    <property>
        <name>hbase.tmp.dir</name>
        <value>/home/hadoop/opt/hbase-1.4.6/tmp</value>
    </property>
    <property>
        <name>hbase.master</name>
        <value>hdfs://master:60000</value>
    </property>

</configuration>

E：配置hbase的Java_home,配置文件为hbase-env.sh

cd /home/hadoop/opt/hbase-1.4.6/conf
vim hbase-env.sh
export JAVA_HOME=/home/hadoop/opt/jdk1.8.0_181

4.建立hbase数据文件夹

    因为在上一步中设置了hbase.tmp.dir的目录，这里需要手动建立目录/home/hadoop/opt/hbase-1.4.6/tmp

cd /home/hadoop/opt/hbase-1.4.6
mkdir -p tmp/hbase

5.使用scp将master上的hbase拷贝到每个slave机器上

scp -r /home/hadoop/opt/hbase-1.4.6 hadoop@slave1:/home/hadoop/opt/
scp -r /home/hadoop/opt/hbase-1.4.6 hadoop@slave2:/home/hadoop/opt/
scp -r /home/hadoop/opt/hbase-1.4.6 hadoop@slave3:/home/hadoop/opt/

##拷贝完成之后修改环境变量sudo vim /etc/profile
#Set Hbase Path
export HBASE_HOME=/home/hadoop/opt/hbase-1.4.6
export PATH=$PATH:$HBASE_HOME/bin

#立即生效
source /etc/profile

6.在master上启动habse

     需要保证hdfs和zookeeper服务已开启

#在master上启动
cd /home/hadoop/opt/hbase-1.4.6/bin
start-hbase.sh

#在master和slave上分别输入jps查看开启的服务
jps

　　

    在浏览器中输入http://192.168.74.131:16010/master-status查看

 

7.使用hbase shell创建表

    注意的是在使用shell的时候需要启动hbase集群，zookeeper管理

cd /home/hadoop/opt/hbase-1.4.6/bin
hbase shell

    下面创建这样一张表customer

rowkey	address			info		phone
	province	city	country	age	company
zhangsan	hubei	wuhan	china	24	douyu	101
lisi	guangdong	guangzhou	china	24	netease	102

 

 

 

 

create 'customer','address','info', 'phone'

put 'customer','zhangsan','phone:','101'
put 'customer','zhangsan','address:province','hubie' 
put 'customer','zhangsan','address:city','wuhan' 
put 'customer','zhangsan','address:country','china' 
put 'customer','zhangsan','info:age','24' 
put 'customer','zhangsan','info:company','douyu' 

put 'customer','lisi','phone:','102'
put 'customer','lisi','address:province','guangdong' 
put 'customer','lisi','address:city','guangzhou' 
put 'customer','lisi','address:country','china' 
put 'customer','lisi','info:age','24' 
put 'customer','lisi','info:company','netease'

    扫描所有数据

scan 'customer'

    根据键值查询数据

get 'customer','zhangsan' 
get 'customer','zhangsan','phone' 

    删除指定数据

delete 'customer','lisi','phone'
delete 'customer','lisi'

    修改表结构

disable 'customer' 
alter 'customer',PHONE=>'tel' 
enable 'customer' 

    改变或者添加一个列族

disable 'customer' 
alter 'customer',PHONE=>'tel' ，'VERSION=>5'
enable 'customer

    删除一个列族

disable 'customer' 
alter 'customer', NAME => 'f1', METHOD => 'delete' 
alter 'customer', 'delete' => 'f1' 
enable 'customer

    统计行数

count 'customer'

    表的删除 

drop 'customer'

     退出shell

quit
