hbase(4):hbase集群安装，

1.前提条件hadoop已经安装完成，zookeeper安装完成。 namenode：安装在：hadoop1,hadoop2 zookeeper集群安装在：hadoop4,hadoop5,hadoop6
2.先启动zookeeper （1）启动第一台zookeeper 登陆到hadoop4,hadoop5,hadoop6 #cd /hadoop/zookeeper-3.4.6/bin [root@hadoop4 bin]#./zkServer.sh start （2）启动hadoop集群的hdfs,在hadoop1中进行启动。 [root@hadoop1 sbin]# ./start-dfs.sh
Starting namenodes on [hadoop1 hadoop2]
hadoop1: starting namenode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-namenode-hadoop1.out
hadoop2: starting namenode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-namenode-hadoop2.out
hadoop5: starting datanode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-datanode-hadoop5.out
hadoop6: starting datanode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-datanode-hadoop6.out
hadoop4: starting datanode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-datanode-hadoop4.out
Starting journal nodes [hadoop4 hadoop5 hadoop6]
hadoop6: starting journalnode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-journalnode-hadoop6.out
hadoop5: starting journalnode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-journalnode-hadoop5.out
hadoop4: starting journalnode, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-journalnode-hadoop4.out
Starting ZK Failover Controllers on NN hosts [hadoop1 hadoop2]
hadoop1: starting zkfc, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-zkfc-hadoop1.out
hadoop2: starting zkfc, logging to /hadoop/hadoop-2.6.0/logs/hadoop-root-zkfc-hadoop2.out
[root@hadoop1 sbin]# 检查是否启动成功 http://192.168.37.131:50070/
3.进行hbase进行解压缩将hbase-0.99.2-bin.tar.gz下载文件，上传到/hadoop的目录下面。解压后 [root@hadoop12 hbase-0.99.2]# pwd
/hadoop/hbase-0.99.2
[root@hadoop12 hbase-0.99.2]# ls
bin CHANGES.txt conf docs hbase-webapps lib LICENSE.txt logs NOTICE.txt README.txt
[root@hadoop12 hbase-0.99.2]#
4.修改hbase的配置文件 #cd /hadoop/hbase-0.99.2/conf （1）修改hbase-env.sh      export JAVA_HOME=/usr/java/jdk1.7.0_55
     //告诉hbase使用外部的zk
     export HBASE_MANAGES_ZK=false （2）修改hbase-site.xml hbase-site.xml
     <configuration>
          
        <property>
                <name>hbase.rootdir</name>
                <value>hdfs://ns1/hbase</value>
        </property>
          
        <property>
                <name>hbase.cluster.distributed</name>
                <value>true</value>
        </property>
          
        <property>
                <name>hbase.zookeeper.quorum</name>
                <value>hadoop4:2181,hadoop5:2181,hadoop6:2181</value>         </property>
     </configuration>
（3）regionservers修改 hadoop3
hadoop4
hadoop5
hadoop6 （4）拷贝hadoop的core-site.xml与hdfs-site.xml到hbase的conf目录。 scp /hadoop/hadoop-2.6.0/etc/hadoop/core-site.xml /hadoop/hbase-0.99.2/conf/ scp /hadoop/hadoop-2.6.0/etc/hadoop/hdfs-site.xml /hadoop/hbase-0.99.2/conf/ 如果不进行拷贝，配置在hbase-site.xml文件中也可以。
（5）拷贝hbase到其他节点           scp -r /hadoop/hbase-0.99.2/ itcast02:/hadoop/           scp -r /hadoop/hbase-0.99.2/ itcast03:/hadoop/           scp -r /hadoop/hbase-0.99.2/ itcast04:/hadoop/           scp -r /hadoop/hbase-0.99.2/ itcast05:/hadoop/           scp -r /hadoop/hbase-0.99.2/ itcast06:/hadoop/
5.将配置好的HBase拷贝到每一个节点并同步时间。
6.启动所有的hbase
（1）分别启动zk
          ./zkServer.sh start
（2）启动hadoop集群
          start-dfs.sh
（3）启动hbase，在主节点上运行： #cd /hadoop/hbase-0.99.2/bin
#./start-hbase.sh 7.查看进程hbase （1）HMaster节点进程 [root@hadoop1 bin]# jps
2703 DFSZKFailoverController
5193 HMaster
5512 Jps
2455 NameNode
You have new mail in /var/spool/mail/root
[root@hadoop1 bin]# （2）子节点进程 [root@hadoop5 bin]# jps
2286 QuorumPeerMain
3389 DataNode
3584 JournalNode
4854 HRegionServer
5061 Jps
You have new mail in /var/spool/mail/root
[root@hadoop5 bin]# （3）页面显示 http://192.168.37.131:16030
8.添加一个Hmaster服务，使得集群更加可靠。在hadoop2机器上启动 #cd /hadoop/hbase-0.99.2/bin [root@hadoop2 bin]# ./hbase-daemon.sh start master
starting master, logging to /hadoop/hbase-0.99.2/logs/hbase-root-master-hadoop2.out
[root@hadoop2 bin]# jps
5349 HMaster
2381 NameNode
2438 DFSZKFailoverController
5412 Jps
