(二)大数据环境准备：Hbase安装步骤(先安装Hadoop)

寂寞大萝卜

1、解压缩： tar -zxvf hbase-0.94.7-security.tar.gz

2、改目录名 mv hbase-0.94.7-security hbase

3、设置HBASE_HOME环境变量
vi /etc/profile

4、修改conf/hbase.env中hbase-env.sh中的如下属性：
export JAVA_HOME=/usr/java/jdk1.6
export HBASE_MANAGES_ZK=true

5、修改hbase-site.xml文件
<configuration>
    <property>
      <name>hbase.rootdir</name>
     <value>hdfs://hadoop0:9000/hbase</value> >
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
</configuration>

6、启动顺序：先启动Hadoop——>再启动Hbase，关闭顺序：先关闭Hbase——>再关闭Hadoop
启动Hadoop：  start-all.sh
启动Hbase：    start-hbase.sh


7、停止顺序，关闭顺序：先关闭Hbase——>再关闭Hadoop
先停止hbase
   stop-hbase.sh
再停止hadoop
   stop-all.sh
