hbase-0.94.7-security.tar.gz集群搭建

1.hbase的机群搭建过程（前是jdk、hadoop、zookeeper环境都已搭建好了）
hadoop1.1.2集群搭建参考我的博客 Hadoop1.1.2集群安装（Vmware+CenterOS6.5.X64） /article/10333044.html
zookeeper搭建可以参考我的博客 Zookeeper学习总结 /article/10333045.html
1.1集群结构，主节点(hmaster)是hadoop01，从节点(regionserver)是hadoop02和hadoop03

[root@hadoop01app]# cd /usr/share/app

[root@hadoop01app]# ls

hadoop-1.1.2 hbase-0.94.7-security.tar.gz zookeeper-3.4.5

[root@hadoop01app]# tar -zxvf hbase-0.94.7-security.tar.gz

[root@hadoop01app]# ls

hadoop-1.1.2 hbase-0.94.7-security hbase-0.94.7-security.tar.gz zookeeper-3.4.5
[root@hadoop01 app]# mv hbase-0.94.7-security hbase（文件夹名称太长，个人喜欢简洁，所以做了修改）

[root@hadoop01app]# cd hbase

[root@hadoop01hbase]# ls

bin CHANGES.txt conf docs hbase-0.94.7-security.jar hbase-0.94.7-security-tests.jar hbase-webapps lib LICENSE.txt NOTICE.txt pom.xml README.txt sbin security src
[root@hadoop01 conf]# echo $JAVA_HOME（修改前查看jdk安装目录，复制）

/usr/local/java/jdk1.7.0_79

1.2修改hadoop0上的hbase的几个文件
(1)修改hbase-env.sh的最后一行exportHBASE_MANAGES_ZK=false

[root@hadoop01conf]# vi hbase-env.sh
exportJAVA_HOME=/usr/local/java/jdk1.7.0_79（改为你的jdk安装目录）
export HBASE_MANAGES_ZK=false（最后一行）

(2)修改hbase-site.xml文件的hbase.zookeeper.quorum的值为hadoop01,hadoop02,hadoop03

[root@hadoop01conf]# vi hbase-site.xml
<property>

<name>hbase.rootdir</name>

<value>hdfs://hadoop01:9000/hbase</value>

</property>

<property>

<name>hbase.cluster.distributed</name>

<value>true</value>

</property>

<property>

<name>hbase.zookeeper.quorum</name>

<value>hadoop01,hadoop02,hadoop03</value>

</property>

<property>

<name>dfs.replication</name>

<value>1</value>

</property>

(3)修改regionservers文件(存放的region server的hostname)，内容修改为hadoop02、hadoop03

[root@hadoop01conf]# vi regionservers

hadoop02

hadoop03

1.3复制hadoop0中的/etc/profile到hadoop1、hadoop2中，在hadoop02、hadoop03上执行source/etc/profile

[root@hadoop01conf]# cd ..

[root@hadoop01hbase]# pwd

/usr/share/app/hbase

[root@hadoop01hbase]# vi /etc/profile

export HBASE_HOME=/usr/share/app/hbase

exportPATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/lib:$ZOOKEEPER_HOME/bin:$HBASE_HOME/bin

[root@hadoop01hbase]# source /etc/profile

[root@hadoop01hbase]# scp -r /etc/profile hadoop02:/etc/

[root@hadoop01 hbase]# scp -r /etc/profile hadoop03:/etc/

[root@hadoop02app]# source /etc/profile

[root@hadoop03 app]#source /etc/profile

复制hadoop0中的hbase文件夹到hadoop02、hadoop03中

[root@hadoop01hbase]# scp -r /usr/share/app/hbase hadoop02:/usr/share/app/

[root@hadoop01 hbase]# scp -r /usr/share/app/hbase hadoop03:/usr/share/app/

1.4 首先启动hadoop，然后启动zookeeper集群。
最后在hadoop01上启动hbase集群，然后jps查看进程。

[root@hadoop01hbase]# start-hbase.sh

startingmaster, logging to /usr/share/app/hbase/logs/hbase-root-master-hadoop01.out

hadoop03:starting regionserver, logging to/usr/share/app/hbase/bin/../logs/hbase-root-regionserver-hadoop03.out

hadoop02:starting regionserver, logging to/usr/share/app/hbase/bin/../logs/hbase-root-regionserver-hadoop02.out

[root@hadoop01hbase]# jps

1271NameNode

2640Jps

2463 HMaster

1395SecondaryNameNode

1470JobTracker

1637QuorumPeerMain

[root@hadoop02app]# jps

2423Jps

2324 HRegionServer

1396QuorumPeerMain

1276TaskTracker

1225DataNode

[root@hadoop03app]# jps

1415QuorumPeerMain

1738 HRegionServer

1224DataNode

1275TaskTracker

1861Jps

OK!Hbase集群搭建成功！
