在Centos7上部署单机版hbase
下载安装包
解压
tar -zxvf hbase-2.2.4.bin.tar.gz
配置hbase-env.sh
部署JDK，查看JAVA_HOME路径。
[root@node1 hbase]# echo $JAVA_HOME /usr/local/bin/jdk1.8.0_112
配置conf/hbase-env.sh
... # 配置java路径 export JAVA_HOME=/usr/local/bin/jdk1.8.0_112 # 配置是否使用自身Zookeeper export HBASE_MANAGES_ZK=true ...
编辑conf/hbase-site.xml

启动
./bin/start-hbase.sh
Web UI
http://192.168.41.128:16010
进入shell命令行
./bin/hbase shell
简单测试
创建一个表，需要指明table name和ColumnFamily name
hbase(main):002:0> create 'test', 'cf' Created table test Took 0.8251 seconds => Hbase::Table - test
确认
hbase(main):004:0> list 'test' TABLE test 1 row(s) Took 0.0077 seconds => ["test"]
describe ‘test’
hbase(main):005:0> describe 'test'
Table test is ENABLED
test
COLUMN FAMILIES DESCRIPTION
{NAME => 'cf', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false', NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE', CACHE_DATA_ON_WRITE => 'false', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', MIN_VERSIONS => '0', REPL
ICATION_SCOPE => '0', BLOOMFILTER => 'ROW', CACHE_INDEX_ON_WRITE => 'false', IN_MEMORY => 'false', CACHE_BLOOMS_ON_WRITE => 'false', PREFETCH_BLOCKS_ON_OPEN => 'false', COMPRESSION => 'NONE', BLOCKCACHE => 'true', BLOCKSIZE => '65536'}
1 row(s)
QUOTAS 0 row(s)
Took 0.2132 seconds
写入数据
hbase(main):003:0> put 'test', 'row1', 'cf:a', 'value1' 0 row(s) in 0.0850 seconds hbase(main):004:0> put 'test', 'row2', 'cf:b', 'value2' 0 row(s) in 0.0110 seconds hbase(main):005:0> put 'test', 'row3', 'cf:c', 'value3' 0 row(s) in 0.0100 seconds
查看写入的数据
hbase(main):006:0> scan 'test' ROW COLUMN+CELL row1 column=cf:a, timestamp=1586504678931, value=value1 row2 column=cf:b, timestamp=1586504712029, value=value2 row3 column=cf:c, timestamp=1586504717104, value=value3 3 row(s) in 0.0230 seconds
获取一行数据
hbase(main):007:0> get 'test', 'row1' COLUMN CELL cf:a timestamp=1586504678931, value=value1 1 row(s) in 0.0350 seconds
获取一个字段
hbase(main):007:0> get 'test', 'row1','cf:a' COLUMN CELL cf:a timestamp=1586504678931, value=value1 1 row(s) in 0.0350 seconds
返回一个字段的多个版本值
默认Hbase列族最多保存一个版本的数据，可以通过下面命令修改,也可以使用HColumnDescriptor：
alter 'test', NAME => 'cf', VERSIONS => 3
从HBase 0.98.2开始，您可以通过在hbase-site.xml中设置hbase.column.max.version为所有新创建列保留的最大版本数指定一个全局默认值。
get 'test', 'row1', {COLUMN=>'cf:a',VERSIONS=>3}
禁用或者恢复表
hbase(main):008:0> disable 'test' 0 row(s) in 1.1820 seconds hbase(main):009:0> enable 'test' 0 row(s) in 0.1770 seconds
添加一个列族
hbase(main):012:0> alter 'test',{NAME=>'haha'}
Updating all regions with the new schema...
1/1 regions updated.
Done.
Took 2.0149 seconds
hbase(main):014:0> alter 'test',NAME=>'hehe' Updating all regions with the new schema... 1/1 regions updated. Done. Took 1.9555 seconds
删除一个列族
hbase(main):009:0> alter 'test',{NAME=>'haha',METHOD=>'delete'}
Updating all regions with the new schema...
1/1 regions updated.
Done.
Took 1.9296 seconds
hbase(main):013:0> alter 'test','delete'=>'haha' Updating all regions with the new schema... 1/1 regions updated. Done. Took 1.8706 seconds
# 添加一个列族，同时删除一个列族
hbase(main):011:0> alter 'test', {NAME => 'hehe'}, {NAME => 'myInfo', METHOD => 'delete'}
Updating all regions with the new schema...
1/1 regions updated.
Done.

清空表
hbase(main):013:0> truncate 'test' Truncating 'test' table (it may take a while): - Disabling table... - Truncating table... 0 row(s) in 3.6760 seconds
删除表
删除表或者修改表的配置前，需要禁用表
hbase(main):011:0> drop 'test' 0 row(s) in 0.1370 seconds
退出Shell
quit 或者 Ctrl+D
停止Hbase
./bin/stop-hbase.sh
