Hbase 配置流程

点击有惊喜

配置Hbase之前需要先配置一下ZooKeeper.
在每台服务器的hosts文件中添加
192.168.111.200 master
192.168.111.199 slave1
192.168.111.198 slave2
如果在之前装集群的时候已经配置过了那么就不用再配置了
随便在某一台上解压zookeeper文件
zoopeeker文件可在官网上下载



下载好将压缩文件上传到任意一台linux系统上
tar -zxvf zookeeper-3.4.8.tar.gz
解压完之后配置/etc/profile文件(我是将文件解压到了/opt/SofteWare文件下)

#zookeeperexport ZOOKEEPER=/opt/SoftWare/zookeeper/zookeeper-3.4.8export PATH=$PATH:$ZOOKEEPER/bin

然后执行source /etc/profile指令 更新
进入刚解压完的文件下的conf目录下
mkdir zoo.cfg文件
然后 cp zoo_sample.cfg zoo.cfg
修改里面的dataDir =//opt/SoftWare/zookeeper/zookeeper-3.4.8/data
添加

server=master:2888:3888server=slave1:2888:3888server=slave2:2888:3888

配置完之后将上述所有内容考到其他节点上
scp -r /opt/SoftWare/zookeeper root@salve1:/opt/SoftWare/
scp -r /opt/SoftWare/zookeeper root@salve2:/opt/SoftWare/
三台机器zookeeper-3.4.8/下面都创建data文件夹
然后再data文件夹中创建一个文件myid
然后里面写上相应的数字 如 master 下 写1
slave1 写 2
salve2 写 3

然后将 /etc/profile文件也按照上述步骤传给各节点 保持文件里面的内容一致
进行到这zookeeper就算配置好了
启动zookeeper zkServer.sh start
查看zookeeper服务状态zkServer.sh status

使用jps查询
结果为QuorumPeerMain

装完zookeeper之后我们来安装HBase

HBase安装配置

下载hbase文件

在任意一台上解压hbase的压缩文件 如在192.168.111.200
tar -xvf hbase-1.2.0-bin.tar.gz
配置添加环境变量到/etc/profile

#hbaseexport HBASE_HOME=/opt/SoftWare/Hbase/hbase-1.2.0export PATH=$PATH:$HBASE_HOME/bin

source /etc/profile

进入hbase的conf目录下 修改三个文件
hbase-env.sh
hbase-site.xml
regionservers
其中hbase-env.sh中 在文档的十多行位置处添加:

# The java implementation to use.  Java 1.7+ required.# export JAVA_HOME=/usr/java/jdk1.6.0/export JAVA_HOME=/opt/SoftWare/Hbase/hbase-1.2.0# Extra Java CLASSPATH elements.  Optional.# export HBASE_CLASSPATH=然后在后面添加：# Seconds to sleep between slave commands.  Unset by default.  This# can be useful in large clusters, where, e.g., slave rsyncs can# otherwise arrive faster than the master can service them.# export HBASE_SLAVE_SLEEP=0.1# Tell HBase whether it should manage it's own instance of Zookeeper or not.export HBASE_MANAGES_ZK=false

重点在于两句话
**
export JAVA_HOME=/opt/SoftWare/Hbase/hbase-1.2.0
export HBASE_MANAGES_ZK=false
**
hbase-site.xml中

<configuration>        <property>                <name>hbase.zookeeper.quorum</name>                <value>master,salve1,salve2</value>                <description>The directory shared by RegionServers.</description>        </property>        <property>                <name>hbase.zookeeper.property.dataDir</name>                <value>/opt/SoftWare/Hbase/hbase-1.2.0/zookeeperdata</value>                <description>Property from ZooKeeper config zoo.cfg.
