一、搭建HBase本地模式

 

解压：                                                                                              

tar -zxvf hbase-1.3.1-bin.tar.gz -C ~/training/                                                               

设置环境变量  vi ~/.bash_profile                                                                                    

 HBASE_HOME=/root/training/hbase-1.3.1                                                                        

 export HBASE_HOME                                                                                                                                                                                  

PATH=$HBASE_HOME/bin:$PATH                                                                                   

 export PATH      

生效环境变量                                                                                            

 source ~/.bash_profile                                                                                       

                                                                                                              

由于本地模式:不需要HDFS，保存在Linux的文件系统                                                                                

    在bigdata11上配置                                                                                              

                                                                                                            

建个目录: mkdir data                                                                                            

修改文件：conf/hbase-env.sh                                                                                      

export JAVA_HOME=/root/training/jdk1.8.0_144                                                              

                                                                                                            

核心配置文件:  conf/hbase-site.xml                                                                                

<property>                                                                                                

  <name>hbase.rootdir</name>                                                                              

  <value>file:///root/training/hbase-1.3.1/data</value>                                                   

</property>                                                                                               

                                                                                                              

启动HBase：start-hbase.sh                                                                                      

starting master, logging to /root/training/hbase-1.3.1/logs/hbase-root-master-bigdata11.out                

只有HMaster ，没有RegionServer                                                                                          

                                                                                                              

                                                                                                            

2、伪分布模式（bigdata11）                                                                                           

修改文件：hbase-env.sh                                                                                           

HBASE_MANAGES_ZK =true     ## 使用HBase自带的ZK

启动Hbase

在HDFS上查看自动生成的hbase目录

 

用网页的方式查看Hbase

192.168.100.11:16010

 

创建’emp’表

create 'emp','depto','ename','job'  

查看表结构  describe 'emp'

或者通过网页查看

                                                                                                          

3、全分布模式：

在bigdata12 、 bigdata13 、 bigdata14  上搭建                                                                   

      解压：tar -zxvf hbase-1.3.1-bin.tar.gz -C /root/training/

                                                                                                        

修改文件：hbase-env.sh                                                                                           

export JAVA_HOME=/root/training/jdk1.8.0_144

文件regionservers：配置从节点地址                                                                                     

192.168.100.13                                                                                           

192.168.100.14                                                                                           

                                                                                                          

复制到其他节点上                                                                                                    

scp -r /root/training/hbase-1.3.1/ root@bigdata13:/root/training                                                        

scp -r /root/training/hbase-1.3.1/ root@bigdata14:/root/training                                                        

启动 Hbase集群

 通过Web Console查看

                                                                                                                                                     4、 Hbase HA 的实现               

在bigdata13再手动启动一个HMaster                                                                                   

hbase-daemon.sh start master                                                                               

     

查看网页状态

bigdata13是Buckup Master

bigdata12是Master

 

把bigdata12的Master   kill掉，然后查看bigdata13的状态，发现已经自动切换到Master状态
