[大数据]Hadoop大数据开发__HBase分布式集群安装部署

1、下载解压HBase

cd /home/hadoop/app
tar -zxvf hbase-2.4.12-bin.tar.gz
rm hbase-2.4.12-bin.tar.gz
ln -s hbase-2.4.12 hbase

2、修改HBase配置文件

cd /home/hadoop/app/hbase/conf

修改hbase-site.sh

<configuration>
  <property>
    <name>hbase.zookeeper.quorum</name>
    <value>hadoop01,hadoop02,hadoop03</value>
  </property>
  <!-- 指定Zookeeper集群节点 -->
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>/home/hadoop/data/zookeeper</value>
  </property>
  <!-- 指定Zookeeper数据存储目录 -->
  <property>
    <name>hbase.zookeeper.property.clientPort</name>
    <value>2181</value>
  </property>
  <!-- 指定Zookeeper端口 -->
  <property>
    <name>hbase.rootdir</name>
    <value>hdfs://mycluster/hbase</value>
  </property>
  <!-- 指定HBase在HDFS上的根目录 -->
  <property>
    <name>hbase.cluster.distributed</name>
    <value>true</value>
  </property>
  <!-- 指定true为分布式集群部署 -->
</configuration>

修改regionservers

#hadoop01、hadoop02、hadoop03都配置为RegionServers
hadoop01
hadoop02
hadoop03

修改backup-masters

hadoop02 #因为HBase的Hmaster为高可用，选择hadoop02为备用节点

修改hbase-env.sh

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HBASE_MANAGES_ZK=false #使用独立的Zookeeper集群

3、配置HBase环境变量

vi ~/.bashrc
JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
ZOOKEEPER_HOME=/home/hadoop/app/zookeeper
HADOOP_HOME=/home/hadoop/app/hadoop
HBASE_HOME=/home/hadoop/app/hbase
CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
PATH=$JAVA_HOME/bin:$HADOOP_HOME/bin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:$PATH
export JAVA_HOME CLASSPATH HADOOP_HOME ZOOKEEPER_HOME HBASE_HOME

4、将hadoop/etc/hadoop中的core-site.xml和hdfs-site.xml复制到hbase的conf目录下

cp /home/hadoop/app/hadoop/etc/hadoop/core-site.xml /home/hadoop/app/hbase/conf
cp /home/hadoop/app/hadoop/etc/hadoop/hdfs-site.xml /home/hadoop/app/hbase/conf

5、HBase安装目录分发到hadoop02、hadoop03

cd /home/hadoop/app
scp -r hbase-2.4.12 hadoop@hadoop02:/home/hadoop/app
scp -r hbase-2.4.12 hadoop@hadoop03:/home/hadoop/app
ln -s hbase-2.4.12 hbase #在hadoop02、hadoop03上生成软连接

6、启动HBase集群

cd /home/hadoop/app/hbase/bin
start-hbase.sh #在hadoop01上启动即可

7、HBase集群状态验证

jps #分别在hadoop01、hadoop02、hadoop03上执行命令，hadoop01和hadoop02上有HMaster和HRegionServer两个进程，hadoop03只有HRegionServer进程
http://hadoop01:16010和http://hadoop02:16010 #一个是Master，一个Backup Master
