1. 启动Hadoop

如果没有安装Hadoop，则查看博文：http://blog.csdn.net/sunnyyoona/article/details/53454430

启动Hadoop并查看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

从上可以知道Hadoop版本为2.7.3版本

2. 下载与解压

我们从官网上下载：http://www.apache.org/dyn/closer.cgi/hbase/

解压到~/opt文件夹下：

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

重命名，便与管理：

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路径以及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"?>

4. 设置环境变量

在/etc/profile配置文件中，创建HBASE_HOME环境变量指向hbase目录，便于以后操作：

1. # hbase
2. export HBASE_HOME=/home/xiaosi/opt/hbase-1.2.4
3. export PATH=${HBASE_HOME}/bin:$PATH

5. 启动Hadoop

进入 Hadoop 主文件夹，开启NameNode和DataNode守护进程：

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. 启动HBase

进入 HBase 主文件夹，开启HMaster和HRegionServer守护进程：

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

通过jps命令查看启动情况：

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. 进入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>

走到这一步，我们已经确定HBase已经安装成功。为了最终验证，可以试试列出HBase中所有表的命令。这个动作执行了一个全程请求，从客户端应用到HBase服务器，然后返回。在Shell提示符下，输入list然后按下回车键：

1. hbase(main):001:0> list
2. TABLE
3. 0 row(s) in 0.1980 seconds
5. => []

完成安装与验证，现在可以创建表并存储一些数据了。

8. 初步使用HBase

创建一个有列族的表student，列族为info：

1. hbase(main):002:0> create 'student', 'info'
2. 0 row(s) in 1.3580 seconds
4. => Hbase::Table - student

再次查看表：

1. hbase(main):003:0> list
2. TABLE
3. student
4. 1 row(s) in 0.0150 seconds
6. => ["student"]
