hbase 集群搭建

上传解压HBase安装包
tar -xvzf hbase-2.1.0.tar.gz -C ../server/

修改HBase配置文件
hbase-env.sh
cd /export/server/hbase-2.1.0/conf
vim hbase-env.sh
export JAVA_HOME=/export/server/jdk1.8.0_241/
export HBASE_MANAGES_ZK=false


hbase-site.xml
vim hbase-site.xml
<configuration>
        <!-- HBase数据在HDFS中的存放的路径 -->
        <property>
            <name>hbase.rootdir</name>
            <value>hdfs://node1:8020/hbase</value>
        </property>
        <!-- Hbase的运行模式。false是单机模式，true是分布式模式。若为false,Hbase和Zookeeper会运行在同一个JVM里面 -->
        <property>
            <name>hbase.cluster.distributed</name>
            <value>true</value>
        </property>
        <!-- ZooKeeper的地址 -->
        <property>
            <name>hbase.zookeeper.quorum</name>
            <value>node1.itcast.cn,node2.itcast.cn,node3.itcast.cn</value>
        </property>
        <!-- ZooKeeper快照的存储位置 -->
        <property>
            <name>hbase.zookeeper.property.dataDir</name>
            <value>/export/server/apache-zookeeper-3.6.0-bin/data</value>
        </property>
        <!--  V2.1版本，在分布式情况下, 设置为false -->
        <property>
            <name>hbase.unsafe.stream.capability.enforce</name>
            <value>false</value>
        </property>
</configuration>



配置环境变量
# 配置Hbase环境变量
vim /etc/profile
export HBASE_HOME=/export/server/hbase-2.1.0
export PATH=$PATH:${HBASE_HOME}/bin:${HBASE_HOME}/sbin

#加载环境变量
source /etc/profile


复制jar包到lib
cp $HBASE_HOME/lib/client-facing-thirdparty/htrace-core-3.1.0-incubating.jar $HBASE_HOME/lib/


2.1.5     修改regionservers文件
vim regionservers 
node1
node2
node3


分发安装包与配置文件
cd /export/server
scp -r hbase-2.1.0/ node2.itcast.cn:$PWD
scp -r hbase-2.1.0/ node3.itcast.cn:$PWD
scp -r /etc/profile node2.itcast.cn:/etc
scp -r /etc/profile node3.itcast.cn:/etc

在node2 和node3 加载环境变量
source /etc/profile


启动HBase
cd /export/onekey
# 启动ZK
./start-zk.sh
# 启动hadoop
start-dfs.sh
# 启动hbase
start-hbase.sh


验证Hbase是否启动成功
# 启动hbase shell客户端
hbase shell
# 输入status

[root@node1 onekey]# hbase shell
