linux上安装hbase

Posted 2020-08-31 wyl9527

1.使用hadoop账号解压到/opt/hadoop目录下：

# su hadoop

$ tar -zxvf hbase-${version} -C /opt/hadoop

$ ln -s hbase-${version}/ hbase

2.进入/opt/hadoop/hbase/conf目录,修改hbase-env.sh文件内容:

export JAVA_HOME=/opt/java

export HBASE_PID_DIR=/opt/hadoop/hadoop/pids

export HADOOP_HOME=/opt/hadoop/hadoop

export HBASE_HOME=/opt/hadoop/hbase

3.修改hbase-site.xml文件内容:

添加下面内容

<configuration>

    <property>

        <name>hbase.rootdir</name>

        <value>hdfs://baseline01:9000/hbase</value>

    </property>

    <property>

        <name>hbase.cluster.distributed</name>

        <value>true</value>

    </property>

    <property>

        <name>hbase.zookeeper.quorum</name>

        <value>baseline01,baseline02,baseline03</value>

    </property>

</configuration>

4.修改/opt/hadoop/hbase/conf/regionservers文件内容:

baseline02

baseline03

5.通过scp复制到其它两台机器上:

$ scp -r /opt/hadoop/hbase-${version} [email protected]baseline02:/opt/hadoop

$ ln -s hbase-${version}/ hbase

$ scp -r /opt/hadoop/hbase-${version} [email protected]:/opt/hadoop

$ ln -s hbase-${version}/ hbase

6.在baseline01上启动hbase集群:

$ /opt/hadoop/hbase/bin/start-hbase.sh

7.查看集群是否启动，运行jps

若baseline01如下所示：

$ jps

22898 ResourceManager

20739 Jps

24383 JobHistoryServer

20286 HMaster

22722 SecondaryNameNode

22488 NameNode

若baseline02和baseline03如下所示：

2141 NodeManager

3257 HRegionServer

25283 Jps

1841 DataNode

显示有HMaster和HRegionServer,则说明启动成功

8.使用/opt/hadoop/hbase/bin/hbase shell命令测试安装结果:

a.创建表test: 

hbase(main):002:0> create "test", "cf"

0 row(s) in 2.5840 seconds

=> Hbase::Table - test

b.列出全部表:

hbase(main):003:0> list

TABLE                                                                                                               

test                                                                                                                

1 row(s) in 0.0310 seconds

=> ["test"]

c.插入数据到test表:

hbase(main):001:0> put "test","row","cf:a","value"

0 row(s) in 0.4150 seconds

d.查看test表信息:

hbase(main):002:0> scan ‘test‘

ROW           COLUMN+CELL                                                                          

row          column=cf:a, timestamp=1447246157917, value=value                                    

1 row(s) in 0.0270 seconds

若hbase shell测试成功，则进入浏览器访问以下网址:

http://baseline01:16010/，若正常显示，则hbase集群安装成功!  用ip保险一点，用域名首先要在自己的电脑host文件中配置。

9.启动thriftserver2服务

$ nohup /opt/hadoop/hbase/bin/hbase-daemon.sh start thrift2 &
