2、解压下载的包

[root@imzcy ~]# tar zxvf hbase-1.1.4-bin.tar.gz -C /opt/
[root@imzcy ~]# cd /opt/hbase-1.1.4/

1 2	[root@imzcy ~]# tar zxvf hbase-1.1.4-bin.tar.gz -C /opt/ [root@imzcy ~]# cd /opt/hbase-1.1.4/

3、修改conf/hbase-env.sh两处配置（此版本位于第27行和第129行）

[root@imzcy hbase-1.1.4]# vi conf/hbase-env.sh
27 export JAVA_HOME=/opt/jdk1.8.0_121
129 export HBASE_MANAGES_ZK=true

[root@imzcy hbase-1.1.4]# vi conf/hbase-env.sh

27 export JAVA_HOME=/opt/jdk1.8.0_121

129 export HBASE_MANAGES_ZK=true

27行:指明JAVA_HOME位置，hbase需要1.7及以上版本的jdk支持（如果系统已经配置过jdk，此行可以不做配置）
129行配置:为true表示指明hbase使用自带的zookeeper

4、配置hbase的root目录，并配置zookeeper地址、端口号及data目录

[root@imzcy hbase-1.1.4]# vi conf/hbase-site.xml
<configuration>
		<property>
			<name>hbase.rootdir</name>
			<value>../data/rootdir</value>
		</property>

	<property>
			<name>hbase.zookeeper.quorum</name>
			<value>127.0.0.1</value>
		</property>
		<property>
			<name>hbase.zookeeper.property.clientPort</name>
			<value>2181</value>
	</property>
		<property>
			<name>hbase.zookeeper.property.dataDir</name>
			<value>../data/zk</value>
		</property>
</configuration>

[root@imzcy hbase-1.1.4]# vi conf/hbase-site.xml

<name>hbase.rootdir</name>

<value>../data/rootdir</value>

</property>

<name>hbase.zookeeper.quorum</name>

</property>

<name>hbase.zookeeper.property.clientPort</name>

</property>

<name>hbase.zookeeper.property.dataDir</name>

</property>

</configuration>

5、启动及停止hbase

5.1、启动hbase

[root@imzcy hbase-1.1.4]# ./bin/start-hbase.sh 
starting master, logging to /opt/hbase-1.1.4/bin/../logs/hbase-root-master-imzcy.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
[root@imzcy hbase-1.1.4]#

[root@imzcy hbase-1.1.4]# ./bin/start-hbase.sh

starting master, logging to /opt/hbase-1.1.4/bin/../logs/hbase-root-master-imzcy.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

[root@imzcy hbase-1.1.4]#

5.2、查看是否正常启动

[root@imzcy hbase-1.1.4]# ps -ef |grep hbase |grep -v grep
root       2841      1  0 20:25 pts/0    00:00:00 bash /opt/hbase-1.1.4/bin/hbase-daemon.sh --config /opt/hbase-1.1.4/bin/../conf foreground_start master

[root@imzcy hbase-1.1.4]#


[root@imzcy ~]# jps -m
3467 HMaster start
[root@imzcy ~]#


[root@imzcy ~]# ss -tnl |grep 2181
LISTEN     0      50          :::2181                    :::*                  
[root@imzcy ~]#

[root@imzcy hbase-1.1.4]# ps -ef |grep hbase |grep -v grep

root 2841 1 0 20:25 pts/0 00:00:00 bash /opt/hbase-1.1.4/bin/hbase-daemon.sh --config /opt/hbase-1.1.4/bin/../conf foreground_start master

root 2855 2841 6 20:25 pts/0 00:00:12 /opt/jdk1.8.0_121/bin/java -Dproc_master -XX:OnOutOfMemoryError=kill -9 %p -XX:+UseConcMarkSweepGC -XX:PermSize=128m -XX:MaxPermSize=128m -Dhbase.log.dir=/opt/hbase-1.1.4/bin/../logs -Dhbase.log.file=hbase-root-master-imzcy.log -Dhbase.home.dir=/opt/hbase-1.1.4/bin/.. -Dhbase.id.str=root -Dhbase.root.logger=INFO,RFA -Dhbase.security.logger=INFO,RFAS org.apache.hadoop.hbase.master.HMaster start

[root@imzcy hbase-1.1.4]#

[root@imzcy ~]# jps -m

3467 HMaster start

[root@imzcy ~]#

[root@imzcy ~]# ss -tnl |grep 2181

LISTEN 0 50 :::2181 :::*

[root@imzcy ~]#

5.3、停止hbase

[root@imzcy hbase-1.1.4]# ./bin/stop-hbase.sh 
stopping hbase.................
[root@imzcy hbase-1.1.4]#

[root@imzcy hbase-1.1.4]# ./bin/stop-hbase.sh

stopping hbase.................

[root@imzcy hbase-1.1.4]#

6、使用CLI对hbase进行一些简单操作

6.1、进入hbase CLI界面

[root@imzcy hbase-1.1.4]# ./bin/hbase shell
2018-09-19 21:02:33,274 WARN  [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 1.1.4, r14c0e77956f9bb4c6edf0378474264843e4a82c3, Wed Mar 16 21:18:26 PDT 2016

hbase(main):001:0>

[root@imzcy hbase-1.1.4]# ./bin/hbase shell

2018-09-19 21:02:33,274 WARN [main] util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

HBase Shell; enter 'help<RETURN>' for list of supported commands.

Type "exit<RETURN>" to leave the HBase Shell

Version 1.1.4, r14c0e77956f9bb4c6edf0378474264843e4a82c3, Wed Mar 16 21:18:26 PDT 2016

hbase(main):001:0>

6.2、使用help命令列出hbase一些基本的使用信息

hbase(main):015:0> help

1	hbase(main):015:0> help

6.3、使用create命令创建一个表

hbase(main):001:0> create 'test', 'cf'
0 row(s) in 2.8620 seconds

=> Hbase::Table - test
hbase(main):002:0>

hbase(main):001:0> create 'test', 'cf'

0 row(s) in 2.8620 seconds

=> Hbase::Table - test

hbase(main):002:0>

6.4、使用list命令列出所有表，后面跟上表明列出指定表信息

hbase(main):003:0> list 'test'
TABLE                                                                                                                                                                  
test                                                                                                                                                                   
1 row(s) in 0.0400 seconds

=> ["test"]
hbase(main):004:0>

hbase(main):003:0> list 'test'

TABLE

test

1 row(s) in 0.0400 seconds

=> ["test"]

hbase(main):004:0>

6.5、使用put命令向表中插入两条数据

hbase(main):004:0> put 'test', 'row1', 'cf:a', 'value1'
0 row(s) in 0.3110 seconds

hbase(main):005:0> put 'test', 'row2', 'cf:b', 'value12'
0 row(s) in 0.0290 seconds

hbase(main):006:0>

hbase(main):004:0> put 'test', 'row1', 'cf:a', 'value1'

0 row(s) in 0.3110 seconds

hbase(main):005:0> put 'test', 'row2', 'cf:b', 'value12'

0 row(s) in 0.0290 seconds

hbase(main):006:0>

6.6、使用scan命令查看表中所有数据

hbase(main):006:0> scan 'test'
ROW                                        COLUMN+CELL                                                                                                                 
 row1                                      column=cf:a, timestamp=1537363958346, value=value1                                                                          
 row2                                      column=cf:b, timestamp=1537364088634, value=value2                                                                         
2 row(s) in 0.0480 seconds

hbase(main):007:0>

hbase(main):006:0> scan 'test'

ROW COLUMN+CELL

row1 column=cf:a, timestamp=1537363958346, value=value1

row2 column=cf:b, timestamp=1537364088634, value=value2

2 row(s) in 0.0480 seconds

hbase(main):007:0>

6.7、使用get命令查看指定行数据

hbase(main):007:0> get 'test', 'row1'
COLUMN                                     CELL                                                                                                                        
 cf:a                                      timestamp=1537363958346, value=value1                                                                                       
1 row(s) in 0.0590 seconds

hbase(main):008:0>

hbase(main):007:0> get 'test', 'row1'

COLUMN CELL

cf:a timestamp=1537363958346, value=value1

1 row(s) in 0.0590 seconds

hbase(main):008:0>

6.8、使用disable命令禁用指定表（hbase删除表或修改表设置时需要先将表禁用）

hbase(main):008:0> disable 'test'
0 row(s) in 2.3450 seconds

hbase(main):009:0>

hbase(main):008:0> disable 'test'

0 row(s) in 2.3450 seconds

hbase(main):009:0>

6.9、使用enable命令启用被禁用的表

hbase(main):009:0> enable 'test'
0 row(s) in 2.5540 seconds

hbase(main):010:0>

hbase(main):009:0> enable 'test'

0 row(s) in 2.5540 seconds

hbase(main):010:0>

6.10、删除指定的表（需要先禁用表，不然会有以下报错）

hbase(main):013:0> drop 'test'
0 row(s) in 1.3290 seconds

hbase(main):014:0>

hbase(main):013:0> drop 'test'

0 row(s) in 1.3290 seconds

hbase(main):014:0>

6.11、使用exit退出CLI界面

hbase(main):014:0> exit
[root@imzcy hbase-1.1.4]#

1 2	hbase(main):014:0> exit [root@imzcy hbase-1.1.4]#

7、常见问题

7.1、如果没有配置好JAVA_HOME，那么启动和停止hbase的时候会报以下错误:

[root@imzcy hbase-1.1.4]# ./bin/start-hbase.sh 
+======================================================================+
|                    Error: JAVA_HOME is not set                       |
+----------------------------------------------------------------------+
| Please download the latest Sun JDK from the Sun Java web site        |
|     > http://www.oracle.com/technetwork/java/javase/downloads        |
|                                                                      |
| HBase requires Java 1.7 or later.                                    |
+======================================================================+
[root@imzcy hbase-1.1.4]#

[root@imzcy hbase-1.1.4]# ./bin/start-hbase.sh

+======================================================================+

+======================================================================+

[root@imzcy hbase-1.1.4]#

7.2 、hbase删除指定表时，如果没有事先禁用该表，则会报以下错误：

hbase(main):010:0> drop 'test'

ERROR: Table test is enabled. Disable it first.

Here is some help for this command:
Drop the named table. Table must first be disabled:
  hbase> drop 't1'
  hbase> drop 'ns1:t1'


hbase(main):011:0>

hbase(main):010:0> drop 'test'

ERROR: Table test is enabled. Disable it first.

Here is some help for this command:

Drop the named table. Table must first be disabled:

hbase> drop 't1'

hbase> drop 'ns1:t1'

hbase(main):011:0>
