hbase集群搭建

前提

• 已经配置好java环境
• 已经搭建zookeeper集群
• 已经搭建Hadoop集群
• 准备3台机器

步骤

1. 拷贝hadoop的hdfs-site.xml和core-site.xml 放到hbase/conf下.

   cp hdfs-site.xml /root/hbase/hbase-1.2.0/conf/
   cp core-site.xml  /root/hbase/hbase-1.2.0/conf/

2. 配置hbase-env.sh

   export JAVA_HOME=/usr/local/java/jdk1.8.0_171
   # 告诉hbase使用外部的zk
   export HBASE_MANAGES_ZK=false

3. 配置hbase-site.xml

   <configuration>
    <property>
        <name>fs.defaultFS</name>
        <!-- hdfs://data1:9000注意和core-site里保持一致 -->
        <value>hdfs://data1:9000/hbase</value>
    </property>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>data1:2181,data2:2181,data3:2181</value>
    </property>
   </configuration>

4. 配置regionservers

   [root@data1 conf]# cat regionservers 
   data2
   data3

5. 配置backup-masters

   echo data2 > backup-masters

6. 将hbase程序及配置拷贝到其它机器

scp -r hbase-1.2.0 root@data2:/root/hbase/
scp -r hbase-1.2.0 root@data3:/root/hbase/

7. 启动hbase

   # 在master节点启动即可
   bin/start-hbase.sh

8. 配置环境变量

   vim /etc/profile
   

export HBASE_HOME=/root/hbase/hbase-1.2.0
export PATH=$PATH:$HBASE_HOME/bin

source /etc/profile

9. 进入hbase
```bash
hbase shell

测试

1. UI

http://master:16010/master-status

2. hbase(main):001:0> create 'test','cf'
   0 row(s) in 1.3920 seconds
   

=> Hbase::Table - test
hbase(main):002:0> list
TABLE
test
1 row(s) in 0.0170 seconds

=> [“test”]
hbase(main):003:0> put ‘test’, ‘row1’, ‘cf:a’, ‘value1’
0 row(s) in 0.1200 seconds

hbase(main):004:0> scan ‘test’
ROW COLUMN+CELL
row1 column=cf:a, timestamp=1629967515721, value=value1
1 row(s) in 0.0210 seconds

hbase(main):005:0>
