hbase不需要编译，只需要选择需要的hadoop版本对应的hbase就可以。比如hbase-0.98.2-hadoop2-bin.tar.gz
1：集群机器间要建立ssh互信
先到所有机器执行下面代码创建rsa
|
mkdir ~/.ssh
|
然后到其中一台机器执行下面命令收集各个集群机器上的私钥
ssh hadoop1 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh hadoop2 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh hadoop3 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
ssh client cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
将收集好的authorized_keys复制到所有集群中机器中
scp ~/.ssh/authorized_keys hadoop2:~/.ssh/
scp ~/.ssh/authorized_keys hadoop1:~/.ssh/
scp ~/.ssh/authorized_keys hadoop3:~/.ssh/
将集群中的authorized_keys文件权限设置为600 。不设置的话互信会不成功哦。
chmod 600 ~/.ssh/authorized_keys
2进入解压后的hbase-0.98.2-hadoop2-bin.tar.gz，修改hbase-0.98.2-hadoop2-bin/conf/hbase-site.xml
添加如下配置：
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://mycluster/hbase</value>
<description>The directory shared by RegionServers.
</description>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop1,hadoop2,hadoop3</value>
</property>
</configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://mycluster/hbase</value>
<description>The directory shared by RegionServers.
</description>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>hadoop1,hadoop2,hadoop3</value>
</property>
</configuration>
3：将这个配置好后的hbase拷贝到所有集群中相同的位置
4：在hdfs中新建/hbase目录，并修改所有者为hbase的启停用户,这个/hbase目录是hbase-site.xml中配置的hdfs://mycluster/hbase
hadoop fs -mkdir /hbase
hadoop fs -chown hbase /hbase
5:hbase启停用户需要配置hadoop环境变量，不然如果你配置了hdfs ha，在hbase-site.xml里面指定的 HBASE.ROOTDIR地址hbase就不认识
export JAVA_HOME=/usr/java/jdk1.7.0_45
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export HADOOP_HOME=/usr/local/hadoop
export PATH=$PATH:$HADOOP_HOME/bin
export HADOOP_INSTALL=/usr/local/hadoop

6：启动hbase和停止hbase
HBASE_HOME/bin/start-hbase.sh
HBASE_HOME/bin/stop-hbase.sh
