Hbase的集群安装

hadoop集群的搭建

搭建真正的zookeeper集群

Hbase需要安装在成功部署的Hadoop平台，并且要求Hadoop已经正常启动。

同时，HBase需要集群部署，我们分别把HBase 部署到主机：guoyansi128  guoyansi129  guoyansi130

1.下载hbase-1.2.4-bin.tar.gz;并且上传到/usr/local/src中

2.解压缩并且把解压缩后的文件移动到上级目录

3.修改 /usr/lcoal/hbase-1.4.8/conf/hbase-env.sh文件

去掉exprot JAVA_HOME前面的#号，并且修改jdk安装目录

4.修改conf/hbasie-site.xml文件

<configuration>
    <property>
        <name>hbase.cluster.distributed</name>
        <value>true</value>
    </property>
    <property>
        <name>hbase.rootdir</name>
        <value>hdfs://guoyansi128:9000/hbase</value>
    </property>
    <property>
        <name>hbase.zookeeper.quorum</name>
        <value>guoyansi128</value>

    <property>
        <name>hbase.master.info.port</name>
        <value>60010</value>
    </property>
</configuration>

5.设置regionservers，该文件在conf下

regionservers文件类似Hadoop的slaves文件，启动HBase的时候,系统将根据该文件建立HBase集群。

6.设置linux的环境变量文件

cd 
ls -a
vim .bash_profile 

#HBase
export HBASE_HOME=/usr/local/hbase-1.4.8/
export PATH=$BASE_HOME/bin:$PATH
export HADOOP_CLASSPATH=$HBASE_HOME/lib/*

 7.启动HBase    进入/usr/local/Hbase-1.4.8/bin

./start-hbase.sh

8.查看启动是否成功

jps

主节点显示的是HBase，从节点显示的是HRegionServer

在浏览器上输入地址：192.168.123.128：60010是否能够正常显示：

 HBase使用独立安装的zookeeper

1.修改conf/hbase-env.sh文件

HBASE_MANGES_ZK=false表示不启用自带的zookeeper。true表示使用hbase自带的zookeeper

 2.将独立安装的zookeeper的配置文件复制到HBase的CLASSPATH

cp /usr/local/zookeeper/conf/zoo.cfg /usr/local/hbase-1.4.8/conf
