1. 啟動Hadoop

如果沒有安裝Hadoop，則檢視博文：

http://blog.csdn.net/sunnyyoona/article/details/53454430

啟動Hadoop并檢視Hadoop版本：

1. xiaosi@yoona:~/opt/hadoop-2.7.3$ sbin/start-dfs.sh

2. Starting namenodes on [localhost]

3. localhost: starting namenode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-namenode-yoona.out

4. localhost: starting datanode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-datanode-yoona.out

5. Starting secondary namenodes [0.0.0.0]

6. 0.0.0.0: starting secondarynamenode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-secondarynamenode-yoona.out

7. xiaosi@yoona:~/opt/hadoop-2.7.3$ bin/hadoop version

8. Hadoop 2.7.3

9. Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r baa91f7c6bc9cb92be5982de4719c1c8af91ccff

10. Compiled by root on 2016-08-18T01:41Z

11. Compiled with protoc 2.5.0

12. From source with checksum 2e4ce5f957ea4db193bce3734ff29ff4

13. This command was run using /home/xiaosi/opt/hadoop-2.7.3/share/hadoop/common/hadoop-common-2.7.3.jar

從上可以知道Hadoop版本為2.7.3版本

2. 下載下傳與解壓

我們從官網上下載下傳：

http://www.apache.org/dyn/closer.cgi/hbase/

解壓到~/opt檔案夾下：

1. xiaosi@yoona:~$ tar -zxvf hbase-1.2.4-bin.tar.gz -C opt/

重命名，便與管理：

1. xiaosi@yoona:~$ cp hbase-1.2.4-bin.tar.gz hbase-1.2.4

3. 配置

修改hbase-env.sh，配置JDK路徑以及Zookeeper：

1. # The java implementation to use.  Java 1.7+ required.

2. export JAVA_HOME=/home/xiaosi/opt/jdk-1.8.0

3. # Tell HBase whether it should manage it's own instance of Zookeeper or not.

4. export HBASE_MANAGES_ZK=true

修改hbase-site.xml

1. <?xml version="1.0"?>

2. <?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

3. <!--

4. 設定環境變量

在/etc/profile配置檔案中，建立HBASE_HOME環境變量指向hbase目錄，便于以後操作：

1. # hbase

2. export HBASE_HOME=/home/xiaosi/opt/hbase-1.2.4

3. export PATH=${HBASE_HOME}/bin:$PATH

5. 啟動Hadoop

進入 Hadoop 主檔案夾，開啟NameNode和DataNode守護程序：

1. xiaosi@yoona:~/opt/hadoop-2.7.3$ cd ~

2. xiaosi@yoona:~$ cd $HADOOP_HOME

3. xiaosi@yoona:~/opt/hadoop-2.7.3$ sbin/start-dfs.sh

4. Starting namenodes on [localhost]

5. localhost: starting namenode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-namenode-yoona.out

6. localhost: starting datanode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-datanode-yoona.out

7. Starting secondary namenodes [0.0.0.0]

8. 0.0.0.0: starting secondarynamenode, logging to /home/xiaosi/opt/hadoop-2.7.3/logs/hadoop-xiaosi-secondarynamenode-yoona.out

6. 啟動HBase

進入 HBase 主檔案夾，開啟HMaster和HRegionServer守護程序：

1. xiaosi@yoona:~/opt/hbase-1.2.4$ bin/start-hbase.sh

2. localhost: starting zookeeper, logging to /home/xiaosi/opt/hbase-1.2.4/bin/../logs/hbase-xiaosi-zookeeper-yoona.out

3. starting master, logging to /home/xiaosi/opt/hbase-1.2.4/logs/hbase-xiaosi-master-yoona.out

4. Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0

5. Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

6. starting regionserver, logging to /home/xiaosi/opt/hbase-1.2.4/logs/hbase-xiaosi-1-regionserver-yoona.out

通過jps指令檢視啟動情況：

1. xiaosi@yoona:~/opt/hbase-1.2.4$ jps

2. 1536 Jps

3. 915 HQuorumPeer

4. 22886 SecondaryNameNode

5. 22678 DataNode

6. 1117 HRegionServer

7. 989 HMaster

8. 22511 NameNode

7. 進入Hbase Shell

1. xiaosi@yoona:~/opt/hbase-1.2.4$ bin/hbase shell

2. SLF4J: Class path contains multiple SLF4J bindings.

3. SLF4J: Found binding in [jar:file:/home/xiaosi/opt/hbase-1.2.4/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]

4. SLF4J: Found binding in [jar:file:/home/xiaosi/opt/hadoop-2.7.3/share/hadoop/common/lib/slf4j-log4j12-1.7.10.jar!/org/slf4j/impl/StaticLoggerBinder.class]

5. SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

6. SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]

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

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

9. Version 1.2.4, r67592f3d062743907f8c5ae00dbbe1ae4f69e5af, Tue Oct 25 18:10:20 CDT 2016

11. hbase(main):001:0>

走到這一步，我們已經确定HBase已經安裝成功。為了最終驗證，可以試試列出HBase中所有表的指令。這個動作執行了一個全程請求，從用戶端應用到HBase伺服器，然後傳回。在Shell提示符下，輸入list然後按下Enter鍵：

1. hbase(main):001:0> list

2. TABLE

3. 0 row(s) in 0.1980 seconds

5. => []

完成安裝與驗證，現在可以建立表并存儲一些資料了。

8. 初步使用HBase

建立一個有列族的表student，列族為info：

1. hbase(main):002:0> create 'student', 'info'

2. 0 row(s) in 1.3580 seconds

4. => Hbase::Table - student

再次檢視表：

1. hbase(main):003:0> list

2. TABLE

3. student

4. 1 row(s) in 0.0150 seconds

6. => ["student"]
