## 下载解压最新版本 ##

HBase下载地址 ：[http://archive.apache.org/dist/hbase/][http_archive.apache.org_dist_hbase] 点击stable目录选择不同版本，然后下载后缀为 .tar.gz 的文件; 例如 hbase-0.98.9-hadoop2-bin.tar.gz，解压缩，然后解压到指定的目录.

# tar -zxvf hbase-0.98.9-hadoop2-bin.tar.gz -C /usr/local

## \- jdk1.6以上版本配置 ##

如果你在命令行键入java有反应说明你安装了Java。如果没有装，你需要先安装，然后编辑conf/hbase-env.sh，将其中的JAVA\_HOME指向到你Java的安装目录。

# vi conf/hbase-env.sh

![这里写图片描述][SouthEast]

## \- 去配置hbase.rootdir ##

编辑 conf/hbase-site.xml 去配置hbase.rootdir，来选择HBase将数据写到哪个目录 将 DIRECTORY 替换成你期望写文件的目录. 默认 hbase.rootdir 是指向 /tmp/hbase-$\{user.name\} ，也就说你会在重启后丢失数据(重启的时候操作系统会清理/tmp目录)

# vi conf/hbase-site.xml

![这里写图片描述][SouthEast 1]

## \- 启动 HBase ##

# ./bin/start-hbase.sh starting Master, logging to logs/hbase-user-master-example.org.out

*  客户端访问结果

![这里写图片描述][SouthEast 2]

## \- 用shell连接你的HBase ##

# ./bin/hbase shell
    
    HBase Shell; enter 'help<RETURN>' for list of supported commands.
    Type "exit<RETURN>" to leave the HBase Shell
    Version: 0.90.0, r1001068, Fri Sep 24 13:55:42 PDT 2010
    
    hbase(main):001:0>

*  输入 help 然后 可以看到一列shell命令。这里的帮助很详细，要注意的是表名，行和列需要加引号。

hbase(main):001:0> help
    HBase Shell, version 0.98.9-hadoop2, r96878ece501b0643e879254645d7f3a40eaf101f, Mon Dec 15 23:00:20 PST 2014
    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.

      Group name: general
      Commands: status, table_help, version, whoami

      Commands: alter, alter_async, alter_status, create, describe, disable, disable_all, drop, drop_all, enable, enable_all, exists, get_table, is_disabled, is_enabled, list, show_filters
    
      Group name: namespace
      Commands: alter_namespace, create_namespace, describe_namespace, drop_namespace, list_namespace, list_namespace_tables
    
      Group name: dml
      Commands: append, count, delete, deleteall, get, get_counter, incr, put, scan, truncate, truncate_preserve
    
      Group name: tools
      Commands: assign, balance_switch, balancer, catalogjanitor_enabled, catalogjanitor_run, catalogjanitor_switch, close_region, compact, compact_rs, flush, hlog_roll, major_compact, merge_region, move, split, trace, unassign, zk_dump
    
      Group name: replication

      Group name: snapshots
      Commands: clone_snapshot, delete_all_snapshot, delete_snapshot, list_snapshots, restore_snapshot, snapshot
    
      Group name: security
      Commands: grant, revoke, user_permission
    
      Group name: visibility labels
      Commands: add_labels, clear_auths, get_auths, list_labels, set_auths, set_visibility
    
    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. For more on the HBase Shell, see http://hbase.apache.org/book.htm

*  创建一个名为 test 的表，这个表只有一个 列族 为 cf。可以列出所有的表来检查创建情况，然后插入些值

hbase(main):003:0> create 'test', 'cf'
    
    0 row(s) in 1.2200 seconds
    
    hbase(main):003:0> list 'table'
    test
    1 row(s) in 0.0550 seconds

*  分别插入了3行。第一个行key为row1, 列为 cf:a， 值是 value1。HBase中的列是由 列族前缀和列的名字组成的，以冒号间隔。例如这一行的列名就是a.

hbase(main):004:0> put 'test', 'row1', 'cf:a', 'value1'
    0 row(s) in 0.0560 seconds
    hbase(main):005:0> put 'test', 'row2', 'cf:b', 'value2'
    0 row(s) in 0.0370 seconds
    hbase(main):006:0> put 'test', 'row3', 'cf:c', 'value3'
    0 row(s) in 0.0450 seconds

*  检查插入情况.

hbase(main):007:0> scan 'test'
    
    ROW        COLUMN+CELL
    row1       column=cf:a, timestamp=1288380727188, value=value1
    row2       column=cf:b, timestamp=1288380738440, value=value2
    row3       column=cf:c, timestamp=1288380747365, value=value3
    3 row(s) in 0.0590 seconds

*  Get一行，操作如下

hbase(main):008:0> get 'test', 'row1'
    COLUMN      CELL
    cf:a        timestamp=1288380727188, value=value1
    1 row(s) in 0.0400 seconds

*  disable 再 drop 这张表，可以清除你刚刚的操作

hbase(main):012:0> disable 'test'
    0 row(s) in 1.0930 seconds
    hbase(main):013:0> drop 'test'
    0 row(s) in 0.0770 seconds

*  关闭shell，用exit/quit

hbase(main):014:0> exit

*  运行停止脚本来停止HBase.

# ./bin/stop-hbase.sh
    stopping hbase...............
