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

hd2
hd3
hd4

#
/home/hadoop/hadoop/etc/hadoop/core-site.xml

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
