HBASE 0.98版本安装，二步曲：安装HADOOP到集群

43tfwed

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
