記HBase叢集安裝

HBase實驗環境：

172.16.110.133 laodeng3.localdomain
172.16.110.132 laodeng2.localdomain
172.16.110.134 laodeng4.localdomain

使用者:hbase password:hbase

Node Name          Master    Zookeeper    RegionServer
172.16.110.133       Y          Y               N
172.16.110.134      backup      Y               Y
172.16.110.132       N          Y               Y

下載hbase的安裝包
http://mirror.bit.edu.cn/apache/hbase/hbase-0.98.8/hbase-0.98.8-hadoop2-bin.tar.gz

步驟
一、Password-Less SSH Access
1、配置133 到134、132 的 hbase使用者Password-Less SSH Access

2、134為backup master
配置在134-〉133的hbase使用者Password-Less SSH Access

二、133上的配置
安裝jdk 1.6 (其他兩個節點也要安裝，並配置JAVA_HOME)

安裝hbase :tar xzvf hbase-0.98.8-hadoop2-bin.tar.gz 到/opt/hbase

1、配置RegionServer
     vi conf/regionservers
     laodeng2.localdomain
     laodeng4.localdomain
2、配置a backup master
     Create a new file in conf/ called backup-masters
      vi conf/backup-masters
      增加laodeng4.localdomain

3、配置Zookeeper （更多配置參考：http://hbase.apache.org/book/zookeeper.html）
    vi conf/hbase-site.xml

      hbase.rootdir
      hdfs://172.16.110.133:9000/hbase


    hbase.cluster.distributed
    true


    hbase.zookeeper.quorum
    laodeng2.localdomain,laodeng3.localdomain,laodeng4.localdomain


    hbase.zookeeper.property.dataDir
    /usr/local/zookeeper


  注意：hbase使用者在/usr/local上要有寫許可權
  注意：zookeeper跑在三個節點上，故還需要在133上打通自身的Password-Less SSH Access
4、配置JAVA_HOME
   vi conf/hbase-env.sh
   export JAVA_HOME=/usr/java/jdk1.6.0_45

5、遠端釋出hbase到132、134上
[hbase@laodeng3 opt]$ scp -r hbase hbase@laodeng4.localdomain:/opt
[hbase@laodeng3 opt]$ scp -r hbase hbase@laodeng2.localdomain:/opt

三、啟動和測試Hbase Cluster

[hbase@laodeng3 hbase]$ ./bin/start-hbase.sh
laodeng3.localdomain: starting zookeeper, logging to /opt/hbase/bin/../logs/hbase-hbase-zookeeper-laodeng3.localdomain.out
laodeng2.localdomain: starting zookeeper, logging to /opt/hbase/bin/../logs/hbase-hbase-zookeeper-laodeng2.localdomain.out
laodeng4.localdomain: starting zookeeper, logging to /opt/hbase/bin/../logs/hbase-hbase-zookeeper-laodeng4.localdomain.out
starting master, logging to /opt/hbase/bin/../logs/hbase-hbase-master-laodeng3.localdomain.out
laodeng2.localdomain: starting regionserver, logging to /opt/hbase/bin/../logs/hbase-hbase-regionserver-laodeng2.localdomain.out
laodeng4.localdomain: starting regionserver, logging to /opt/hbase/bin/../logs/hbase-hbase-regionserver-laodeng4.localdomain.out
laodeng4.localdomain: starting master, logging to /opt/hbase/bin/../logs/hbase-hbase-master-laodeng4.localdomain.out

結果：
[hbase@laodeng3 hbase]$ jps
9893 Jps
9649 HMaster
9584 HQuorumPeer

[hbase@laodeng4 ~]$ jps
12183 HMaster
11948 HQuorumPeer
12398 Jps
12067 HRegionServer

[hbase@laodeng2 ~]$ jps
20800 HRegionServer
20689 HQuorumPeer
21006 Jps

可以查詢到我在偽叢集實驗時建立的表：
