HBASE 0.98版本安装，二步曲：安装HADOOP到集群
1、准备4台服务器
一台作为namenode
192.168.137.101 hd1
三台作为datanode
192.168.137.102 hd2
192.168.137.103 hd3
192.168.137.104 hd4
2、拉平所有服务器的时间
使用ntpdate
略
3、配置多机互信
略
4、解压hadoop
tar zxvf hadoop-2.2.0.tar.gz
5、移动hadoop到相应位置
mv hadoop-2.2.0 /home/hadoop/hadoop
6、在namenode建立相应目录
应该是755权限
mkdir /home/hadoop/hdfs
mkdir /home/hadoop/namenode
mkdir /home/hadoop/tmp
7、在datanode建立相应的目录
mkdir /home/hadoop/hdfs
mkdir /home/hadoop/tmp
8、配置hadoop
配置文件有7个：
/home/hadoop/hadoop/etc/hadoop/hadoop-env.sh
/home/hadoop/hadoop/etc/hadoop/yarn-env.sh
/home/hadoop/hadoop/etc/hadoop/slaves
/home/hadoop/hadoop/etc/hadoop/core-site.xml
/home/hadoop/hadoop/etc/hadoop/hdfs-site.xml
/home/hadoop/hadoop/etc/hadoop/mapred-site.xml
/home/hadoop/hadoop/etc/hadoop/yarn-site.xml
# /home/hadoop/hadoop/etc/hadoop/hadoop-env.sh
export JAVA_HOME=/java
export HADOOP_HOME=/home/hadoop/hadoop
# /home/hadoop/hadoop/etc/hadoop/yarn-env.sh
export JAVA_HOME=/java
# /home/hadoop/hadoop/etc/hadoop/slaves

hd3
hd4

8、拷贝hadoop到所有datanode
scp -r /home/hadoop/hadoop/ hd2:/home/hadoop/
scp -r /home/hadoop/hadoop/ hd3:/home/hadoop/
scp -r /home/hadoop/hadoop/ hd4:/home/hadoop/
9、格式化namenode
hadoop namenode -format
10、启动dfs
start-dfs.sh
11、查看状态
