1 在Ubuntu中环境准备

系统环境：

Linux Ubuntu 14.04.2 LTS 64bit server
Java 1.7.0_75
Hadoop 1.2.1

HBase安装

2.1 下载HBase

下载地址：http://mirror.tcpdiag.net/apache/hbase/# 解压HBase　tar xvf hbase-0.94.18.tar.gz# 移动HBase目录到文件夹　mv hbase-0.94.18/ /home/liujianfei/hadoop/   cp -rf  hbase-0.94.18/ /home/liujianfei/hadoop/hbase-0.94.18 # 进入目录   cd /home/liujianfei/hadoop/hbase-0.94.182.2 配置HBase
2.2.1 修改启动文件hbase-env.sh
创建目录：
mkdir /home/liujianfei/hadoop/hdata vim conf/hbase-env.sh#打开注释export JAVA_HOME=/home/conan/toolkit/jdk16export HBASE_CLASSPATH=/home/conan/hadoop/hadoop-1.1.2/confexport HBASE_MANAGES_ZK=true
2.2.2 修改配置文件 hbase-site.xml
~ vi conf/hbase-site.xml<configuration><property><name>hbase.rootdir</name><value>hdfs://localhost:9000/hbase</value></property><property><name>hbase.cluster.distributed</name><value>true</value></property><property><name>dfs.replication</name><value>1</value></property><property><name>hbase.zookeeper.quorum</name><value>localhost</value></property><property><name>hbase.zookeeper.property.clientPort</name><value>2181</value></property><property><name>hbase.zookeeper.property.dataDir</name><value>/home/liujianfei/hadoop/hdata</value></property></configuration>
2.3 启动hadoop和hbase
  ./home/liujianfei/hadoop/hadoop-1.2.1/bin/start-all.sh  ./home/liujianfei/hadoop/hbase-0.94.18/bin/start-hbase.sh# 查看hbase进程~ jps4647 JobTracker4824 TaskTracker4556 SecondaryNameNode7589 HQuorumPeer4356 DataNode7660 HMaster8248 Main9007 Jps3859 org.eclipse.equinox.launcher_1.3.0.dist.jar4076 NameNode7797 HRegionServer2.4 打开HBase命令行客户端访问Hbase进入cd /home/liujianfei/hadoop/hbase-0.94.18/bin./hbase shell2.5 HBase简单命令操作
