HBASE详解大数据

1. 进入/usr
   cd /usr

2. 解压hbase
   tar -xzvf hbase-1.3.1-bin.tar.gz

3. 删除包
   rm -rf hbase-1.3.1-bin.tar.gz

4. 修改文件名
   mv hbase-1.3.1/ hbase

5. 修改profile
   vi /etc/profile

6. 添加如下代码

    export ZK_HOME=/usr/zookeeper 
    export HBASE_HOME=/usr/hbase 
 
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$HADOOP_HOME/bin:${HBASE_HOME}:${ZK_HOME}/bin:$PATH

1. 执行生效
   source /etc/profile

2. 进入hbase cd /usr/hbase修改hbase-env.sh文件
   vi conf/hbase-env.sh

3. 添加如下代码

export JAVA_HOME=/usr/java/jdk1.8.0_131 
export HADOOP_HOME=/usr/hadoop 
export HBASE_HOME=/usr/hbase 
export HBASE_CLASSPATH=/usr/hadoop/etc/hadoop 
export HBASE_PID_DIR=/usr/hbase/pids 
export HBASE_MANAGES_ZK=false

1. 修改配置文件hbase-site.xml
   vi conf/hbase-site.xml

2. 添加如下代码
   <configuration>
   <!– Site specific YARN configuration properties –>
   <property>
   <name>hbase.rootdir</name>
   <value>hdfs://centos201:9000/hbase</value>
   <description>The directory shared byregion servers.</description>
   </property>
   <property>
   <name>hbase.master</name>
   <value>centos201</value>
   </property>
   <property>
   <name>hbase.zookeeper.property.clientPort</name>
   <value>2181</value>
   <description>Property from ZooKeeper’sconfig zoo.cfg. The port at which the clients will connect.
   </description>
   </property>
   <property>
   <name>zookeeper.session.timeout</name>
   <value>120000</value>
   </property>
   <property>
   <name>hbase.zookeeper.quorum</name>
   <value>centos201,centos202,centos203</value>
   </property>
   <property>
   <name>hbase.tmp.dir</name>
   <value>/usr/hbase/tmp</value>
   </property>
   <property>
   <name>hbase.cluster.distributed</name>
   <value>true</value>
   </property>
   </configuration>

3. 创建tmp
   mkdir tmp mkdir pids

4. 修改regionservers文件
   vi conf/regionservers

5. 添加如下代码
   centos201
   centos202
   centos203

6. 授权
   chown -R wuyang:wuyang /usr/hbase/

7. 切换用户
   su wuyang

8. 启动
   首先要启动hdfs和zookeeper

   bin/start-hbase.sh

9. 查看
   bin/hbase shell
   

10. 测试
    status
11. 退出
    exit
