【Hadoop】HBase组件配置
目录
HBase实验步骤：
需要在Hadoop-全分布式配置的基础上进行配置
1、配置时间同步（所有节点）
[root@master ~]# yum -y install chrony
[root@master ~]# vi /etc/chrony.conf
server 0.time1.aliyun.com iburst
#保存
[root@master ~]# systemctl restart chronyd
[root@master ~]# systemctl enable chronyd
Created symlink from /etc/systemd/system/multi-user.target.wants/chronyd.service to /usr/lib/systemd/system/chronyd.service.
[root@master ~]# systemctl status chronyd
● chronyd.service - NTP client/server
Loaded: loaded (/usr/lib/systemd/system/chronyd.service; enabled; vendor preset: enabled)
Active: active (running) since Fri 2022-04-15 15:39:55 CST; 23s ago
Main PID: 1900 (chronyd)
CGroup: /system.slice/chronyd.service
└─1900 /usr/sbin/chronyd
#看到running则表示成功
2、部署HBase（master节点）
先使用xftp上传hbase软件包至/opt/software
# 解压
[root@master ~]# tar xf /opt/software/hbase-1.2.1-bin.tar.gz -C /usr/local/src/
[root@master ~]# cd /usr/local/src/
[root@master src]# mv hbase-1.2.1 hbase
[root@master src]# ls
hadoop hbase hive jdk
# 配置hbase环境变量
[root@master src]# vi /etc/profile.d/hbase.sh
export HBASE_HOME=/usr/local/src/hbase
export PATH=${HBASE_HOME}/bin:$PATH
#保存
[root@master src]# source /etc/profile.d/hbase.sh
[root@master src]# echo $PATH
/usr/local/src/hbase/bin:/usr/local/src/jdk/bin:/usr/local/src/hadoop/bin:/usr/local/src/hadoop/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/usr/local/src/hive/bin:/root/bin
#看到环境变量中有hbase的路径则表示成功
3、配置HBase（master节点）
# 配置HBase
[root@master src]# cd /usr/local/src/hbase/conf/
[root@master conf]# vi hbase-env.sh
export JAVA_HOME=/usr/local/src/jdk
export HBASE_MANAGES_ZK=true
export HBASE_CLASSPATH=/usr/local/src/hadoop/etc/hadoop/
#保存
[root@master conf]# vi hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://master:9000/hbase</value>
</property>
<property>
<name>hbase.master.info.port</name>
<value>60010</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>zookeeper.session.timeout</name>
<value>10000</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>master,slave1,slave2</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/usr/local/src/hbase/tmp</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
</configuration>
#保存
[root@master conf]# vi regionservers
192.168.100.20
192.168.100.30
#保存
[root@master conf]# mkdir -p /usr/local/src/hbase/tmp
4、拷贝文件到slave节点
# master节点
[root@master conf]# scp -r /usr/local/src/hbase slave1:/usr/local/src/
[root@master conf]# scp -r /usr/local/src/hbase slave2:/usr/local/src/
[root@master conf]# scp /etc/profile.d/hbase.sh slave1:/etc/profile.d/
[root@master conf]# scp /etc/profile.d/hbase.sh slave2:/etc/profile.d/
5、修改权限，切换用户（所有节点）
# master节点
[root@master conf]# chown -R hadoop.hadoop /usr/local/src
[root@master conf]# ll /usr/local/src/
total 0
drwxr-xr-x. 12 hadoop hadoop 183 Apr 9 09:57 hadoop
drwxr-xr-x 8 hadoop hadoop 171 Apr 15 15:59 hbase
drwxr-xr-x. 11 hadoop hadoop 215 Apr 9 10:40 hive
drwxr-xr-x. 8 hadoop hadoop 255 Sep 14 2017 jdk
[root@master conf]# su - hadoop
# slave1节点
[root@slave1 ~]# chown -R hadoop.hadoop /usr/local/src
[root@slave1 ~]# ll /usr/local/src/
total 0
drwxr-xr-x. 12 hadoop hadoop 183 Apr 9 09:59 hadoop
drwxr-xr-x 8 hadoop hadoop 171 Apr 15 16:19 hbase
drwxr-xr-x. 8 hadoop hadoop 255 Apr 8 17:24 jdk
[root@slave1 ~]# su - hadoop
# slave2节点
[root@slave2 ~]# ll /usr/local/src/
总用量 0
drwxr-xr-x. 12 hadoop hadoop 183 4月 9 09:59 hadoop
drwxr-xr-x 8 hadoop hadoop 171 4月 15 16:19 hbase
drwxr-xr-x. 8 hadoop hadoop 255 4月 8 17:24 jdk
[root@slave2 ~]# su - hadoop
6、启动hadoop（master节点）
#在master上启动分布式hadoop集群
[hadoop@master ~]$ start-all.sh
[hadoop@master ~]$ jps
3210 Jps
2571 NameNode
2780 SecondaryNameNode
2943 ResourceManager
# 查看slave1节点
[hadoop@slave1 ~]$ jps
2512 DataNode
2756 Jps
2623 NodeManager
# 查看slave2节点
[hadoop@slave2 ~]$ jps
3379 Jps
3239 NodeManager
3135 DataNode
#确保master上有NameNode、SecondaryNameNode、 ResourceManager进程, slave节点上要有DataNode、NodeManager进程
7、启动hbase（master节点）
[hadoop@master ~]$ start-hbase.sh
[hadoop@master ~]$ jps
3569 HMaster
2571 NameNode
2780 SecondaryNameNode
3692 Jps
2943 ResourceManager
3471 HQuorumPeer
# 查看slave1节点
[hadoop@slave1 ~]$ jps
2512 DataNode
2818 HQuorumPeer
2933 HRegionServer
3094 Jps
2623 NodeManager
# 查看slave2节点
[hadoop@slave2 ~]$ jps
3239 NodeManager
3705 Jps
3546 HRegionServer
3437 HQuorumPeer
3135 DataNode
#确保master上有HQuorumPeer、HMaster进程，slave节点上要有HQuorumPeer、HRegionServer进程
8、查看浏览器页面
在windows主机上执行:
在C:\windows\system32\drivers\etc\下面把hosts文件拖到桌面上，然后编辑它加入master的主机名与IP地址的映射关系，在浏览器上输入http://master:60010访问hbase的web界面
192.168.100.10 master master.example.com
192.168.100.20 slave1 slave1.example.com
192.168.100.30 slave2 slave2.example.com
9、hbase语法应用（master节点）
[hadoop@master ~]$ hbase shell
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/local/src/hbase/lib/slf4j-log4j12-1.7.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
