HBase HA 集群搭建

注：安装的Hbase的前提是ZooKeeper和hadoop的集群已经搭建完毕。（ZooKeeper和hadoop（高可用集群）具体安装细节可以在网上查找）同时意味着防火墙、JDK、SSH免密登陆已经完成。

1、集群配置简介：

2、下载Hbase稳定版

hbase-1.2.6-bin.tar.gz 

3、上传到SecureCRT

使用命令：rz -y回车弹出如下截图

4、解压，更名

5、修改配置文件

5.1 hbase-env.sh修改以下配置信息

使环境变量生效：source ---

5.2修改配置文件hbase-site.xml

<configuration>   <property>         <name>hbase.rootdir</name>         <value>hdfs://mycluster/hbase</value>   </property>   <property>         <name>hbase.master.port</name>         <value>16000</value>     </property>   <property>         <name>hbase.master.info.port</name>         <value>16010</value>     </property>   <property>         <name>hbase.tmp.dir</name>         <value>/home/soft/hbase/tmp</value>     </property>   <property>        <name>hbase.cluster.distributed</name>        <value>true</value>   </property>   <property>        <name>hbase.zookeeper.quorum</name>        <value>Slave1,Slave2,Slave3</value>   </property>   <property>         <name>hbase.zookeeper.property.clientPort</name>         <value>2181</value>     </property>   <property>          <name>hbase.zookeeper.property.dataDir</name>          <value>/home/soft/zookeeper/data</value>     </property></configuration>

5.3建议把hadoop以下几个配置文件考入Hbase的conf文件夹下

6. 将Hbase文件发送到其他各个节点上

[hadoop@Master soft]$ scp -r hbase Slave1:/home/soft

[hadoop@Master soft]$ scp -r hbase Slave2:/home/soft

[hadoop@Master soft]$ scp -r hbase Slave3:/home/soft

[hadoop@Master soft]$ scp -r hbase hamaster:/home/soft

配置环境变量（所有虚拟机都要配置）

export JAVA_HOME=/home/soft/Javaexport HADOOP_HOME=/home/soft/hadoopexport HADOOP_INSTALL=$HADOOP_HOMEexport HADOOP_MAPRED_HOME=$HADOOP_HOMEexport HADOOP_COMMON_HOME=$HADOOP_HOMEexport HADOOP_HDFS_HOME=$HADOOP_HOMEexport YARN_HOME=$HADOOP_HOME#export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/nativeexport JRE_HOME=$JAVA_HOME/jreexport MAVEN_HOME=/home/soft/maven#HBASE_HOMEexport HBASE_HOME=/home/soft/hbaseexport PATH=$PATH:$HBASE_HOME/binexport PATH=$PATH:$JAVA_HOME/bin:${MAVEN_HOME}/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:/home/Master/git-2.9.4/bin

使环境变量生效：[hadoop@Master ~]$ source /etc/profile

7.1先启动zookeeper集群：在Slave1、Slave2、Slave3分别启动：zkServer.sh start

jps 查看进程：5593 QuorumPeerMain

7.2 在master（主节点）上启动hadoop集群

start-all.sh

jps查看进程

[hadoop@Master soft]$ jps5956 NameNode6487 Jps6280 DFSZKFailoverController6377 ResourceManager

从节点

[hadoop@Slave1 soft]$ jps5873 NodeManager5794 JournalNode5718 DataNode5593 QuorumPeerMain5919 Jps

7.3在master启动Hbase：start-hbase.h

[hadoop@Master soft]$ start-hbase.sh
starting master, logging to /home/soft/hbase/logs/hbase-hadoop-master-Master.out

Slave3: starting regionserver, logging to /home/soft/hbase/bin/../logs/hbase-hadoop-regionserver-Slave3.out

Slave2: starting regionserver, logging to /home/soft/hbase/bin/../logs/hbase-hadoop-regionserver-Slave2.out
Slave1: starting regionserver, logging to /home/soft/hbase/bin/../logs/hbase-hadoop-regionserver-Slave1.out

hamaster: starting master, logging to /home/soft/hbase/bin/../logs/hbase-hadoop-master-hamaster.out

jps查看进程

[hadoop@Master soft]$ jps
7937 HMaster..................................（Hbase进程）
7253 NameNode
7577 DFSZKFailoverController
7691 ResourceManager
8060 Jps

从节点

[hadoop@Slave1 soft]$ jps
5873 NodeManager
5794 JournalNode
6440 DataNode
6472 Jps
5593 QuorumPeerMain
6138 HRegionServer（Hbase进程启动成功）

查看web页面：Master:16010

至此Hbase部署成功！！！
