Hadoop-HBase-高可用集群部署

1. 启动 Hadoop 集群: Hadoop-集群部署 | Hadoop-高可用集群部署
2. 启动 Zookeeper 集群: Zookeeper-高可用集群部署[DockerSwarm]
3. 修改 HBase 配置文件
   • hbase-env.sh

     export HBASE_PID_DIR=/var/hbase/pids
     export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.19.0.7-1.el9_1.x86_64
     export HBASE_MANAGES_ZK=false
     export HADOOP_HOME=/opt/hadoop/hadoop-3.3.5

   • hbase-site.xml

     <configuration>
         <property>
             <name>hbase.rootdir</name>
             <value>hdfs://hadoop01:9000/hbase</value>
         </property>
         <property>
             <name>hbase.cluster.distributed</name>
             <value>true</value>
         </property>
         <property>
             <name>hbase.zookeeper.quorum</name>
             <value>hadoop01:2181,hadoop02:2181,hadoop03:2181</value>
         </property>
         <property>
             <name>hbase.wal.provider</name>
             <value>filesystem</value>
         </property>
     </configuration>

   • Regionservers

     hadoop01
     hadoop02
     hadoop03

4. 使用 scp -r 把软件复制到其他节点
   • scp -r /opt/hbase/ root@hadoop02:/opt/hbase/
   • scp -r /opt/hbase/ root@hadoop03:/opt/hbase/
5. 配置环境变量
6. 启动主节点Master: start-hbase.sh
7. 启动从节点备用Master: hbase-daemon.sh start master
