1.下载

http://archive.cloudera.com/cdh5/cdh/5/hbase-1.2.0-cdh5.7.5.tar.gz

2.解压  
tar -zxvf hbase-1.2.0-cdh5.7.5.tar.gz

3.修改$HBASE\_HOME/conf/hbase-env.sh

export JAVA\_HOME=/opt/soft/jdk1.8.0\_40

export HBASE\_CLASSPATH=/opt/soft/hadoop-2.6.0-cdh5.7.0/etc/hadoop

export HBASE\_PID\_DIR=/opt/soft/hbase-1.2.0-cdh5.7.5/hbase/pids

export HBASE\_MANAGES\_ZK=true

4.修改$HBASE\_HOME/conf/hbase-site.xml

<property>  
<name>hbase.rootdir</name>  
<value>hdfs://hadoop01:8020/hbase</value>  
</property>  
<property>  
<name>hbase.cluster.distributed</name>  
<value>true</value>  
</property>  
<property>  
<name>hbase.tmp.dir</name>  
<value>/opt/soft/hbase-1.2.0-cdh5.7.5/hbase/tmp</value>  
</property>

5.修改regionservers(将主机名添加进去，每行一个)

hadoop01

6.修改环境变量(添加HBASE\_HOME和PATH)

export HBASE\_HOME=/opt/soft/hbase-1.2.0-cdh5.7.5  
export PATH=$HBASE\_HOME/bin:$PATH

7.启动hbase(打开hbaseUI界面进行查看，默认端口号是60010)

在启动hbase之前，首先启动hdfs的进程，因为hbase的底层存储依赖hdfs

\# bin/start-hbase.sh

8.停止hbase

\# bin/stop-hbase.sh

9.hbase基本的命令使用:

\# cd bin/

\# ./hbase

简单使用一下命令：\# ./hbase shell

hbase(main):004:0> help  
HBase Shell, version 1.2.0-cdh5.7.5, rUnknown, Wed Nov  2 12:02:54 PDT 2016  
Type 'help "COMMAND"', (e.g. 'help "get"' -- the quotes are necessary) for help on a specific command.  
Commands are grouped. Type 'help "COMMAND\_GROUP"', (e.g. 'help "general"') for help on a command group.

SHELL USAGE:  
Quote all names in HBase Shell such as table and column names.  Commas delimit  
command parameters.  Type <RETURN> after entering a command to run it.  
Dictionaries of configuration used in the creation and alteration of tables are  
Ruby Hashes. They look like this:  
  
  
  \{'key1' => 'value1', 'key2' => 'value2', ...\}  
  
  
and are opened and closed with curley-braces.  Key/values are delimited by the  
'=>' character combination.  Usually keys are predefined constants such as  
NAME, VERSIONS, COMPRESSION, etc.  Constants do not need to be quoted.  Type  
'Object.constants' to see a (messy) list of all constants in the environment.  
  
  
If you are using binary keys or values and need to enter them in the shell, use  
double-quote'd hexadecimal representation. For example:  
  
  
  hbase> get 't1', "key\\x03\\x3f\\xcd"  
  hbase> get 't1', "key\\003\\023\\011"  
  hbase> put 't1', "test\\xef\\xff", 'f1:', "\\x01\\x33\\x40"  
  
  
The HBase shell is the (J)Ruby IRB with the above HBase-specific commands added.

创建一张表：

create 'user','info'

查看有多少张表：

list

描述表：

describe 'user'

插入数据：

put 'user','10001','info:name','zhangsan'

put 'user','10001','info:age','25'

数据查询的方式：

\* 依据rowkey查询，最快的(查询结果按照rowkey排序)

get 'user','10001'
