<span>HBase2.x安装</span>

zookeeper的安装

参考Zookeeper集群环境搭建

下载安装包

下载地址：

上传到服务器并解压

tar -zxvf hbase-2.3.4-bin.tar.gz -C /usr/local/

修改配置文件

配置文件目录在conf文件夹中。

（1）修改hbase-env.sh

export JAVA_HOME=/usr/local/jdk1.8
export HBASE_MANAGES_ZK=false

其中HBASE_MANAGES_ZK=false表示指定使用自己搭建的zk集群，而不是hbase自带的zk集群。

(2) 修改hbase-site.xml

 <configuration>
    <property>
      <name>hbase.unsafe.stream.capability.enforce</name>
      <value>false</value>
    </property>
     <property>
         <name>hbase.zookeeper.property.clientPort</name>
         <value>2181</value>
     </property>
     <property>
         <name>hbase.zookeeper.quorum</name>
         <value>hadoop01,hadoop02,hadoop03</value>
     </property>
     <property>
         <name>hbase.rootdir</name>
         <value>hdfs://bigdata02:9000/hbase</value>
     </property>
     <property>
         <name>hbase.cluster.distributed</name>
         <value>true</value>
     </property>
 </configuration>

修改regionservers

vi regionservers
bigdata02
bigdata03
bigdata04

修改backup-masters

该文件是不存在的，先自行创建

vi backup-masters
bigdata04

将HBase安装包分发到其他节点

scp -r hbase-2.3.4/ bigdata03:/usr/local/
scp -r hbase-2.3.4/ bigdata04:/usr/local/

配置环境变量

 vi /etc/profile

export HBASE_HOME=/usr/local/hbase-2.3.4
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin:$PATH
source /etc/profile

启动Hbase

启动顺序,hadoop集群-->zk集群-->hbase HBase启动命令 start-hbase.sh

start-hbase.sh

[root@bigdata02 hbase-2.3.4]# start-hbase.sh

通过浏览器验证启动结果

排错

Q: HMaster进程未启动 A:需要去hbase安装目录下logs文件里查看具体错误信息

cat hbase-root-master-bigdata02.log

如果报的是failed on connection e xception: java.net.ConnectException: Connection refused;请保持core-site中fs.defaultFS配置的端口号和hbase-site.xml中配置的hbase.rootdir端口号相同。 core-site.xml

    <property>
                 <name>fs.defaultFS</name>
                <value>hdfs://bigdata02:9000</value>
    </property>

fs.defaultFS:接收Client连接的RPC端口，用于获取文件系统metadata信息 hbase-site.xml
  <property>
    <name>hbase.tmp.dir</name>
