在229-231上修改/etc/profile
添加

ssh免密码登录
用hadoop用户登录所有机器，在/home/hadoop/下建立.ssh目录
运行
# ssh-keygen -t dsa -P '' -f ~/.ssh/id_dsa
这样会在~/.ssh/生成两个文件：id_dsa 和id_dsa.pub。
# cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys
拷贝authorized_keys到222-232
# scp /home/hadoop/.ssh/authorized_keys hadoop@192.168.0.222:/home/hadoop/.ssh/
修改hosts文件
# sudo vim /etc/hosts
修改所有机器的/etc/hosts文件为
?

拷贝221的hadoop到222-228,232
# scp -r /home/hadoop/cdh3/hadoop-0.20.2-cdh3u0/ hadoop@192.168.0.222:/home/hadoop/cdh3/
格式化hadoop文件系统
# hadoop namenode -format
启动hadoop，在221上运行
# start-all.sh

4、安装zookeeper
在229-231上创建/home/hadoop/zookeeperdata目录
修改229的/home/hadoop/cdh3/zookeeper-3.3.3-cdh3u0/conf/zoo.cfg
?
# The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial # synchronization phase can takeinitLimit=10# The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.dataDir=/home/hadoop/zookeeperdata# the port at which the clients will connectclientPort=2181server.1=ubuntu-9:2888:3888server.2=ubuntu-10:2888:3888server.3=ubuntu-11:2888:3888

启动hbase
在221上执行
# start-hbase.sh
