1.修改主機名

2.修改IP地址

3.添加主機名與ip的映射

dataNodeOneIP dataNodeOne

dataNodeTwoIP dataNodeTwo

nameNodeIP nameNode

slaveNodeIP slaveNode

4.防火墻：

查看：service iptables status

關(guān)閉：service iptables stop

查看開啟狀態(tài)：chkconfig iptables --list

關(guān)閉開機啟動：chkconfig iptables off

驗證：service iptables status

5.拷貝安裝包：

6.關(guān)閉：selinux

驗證：sestatus -v

沒有修改成功就reboot

7.在隱藏文件中導(dǎo)入jdk環(huán)境變量：/home/用戶名/.bash_profile? （.bash_profile隱藏文件）

export JAVA_HOME=/home/用戶名/setupPackage/jdk1.7.0_79

export JRE_HOME=/home/用戶名/setupPackage/jdk1.7.0_79/jre

export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar:$JRE_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

生效環(huán)境變量：source /home/用戶名/.bash_profile

檢查jdk版本:java -version

分發(fā)/home/用戶名/.bash_profile到集群其他機器，并逐個生效環(huán)境變量；

8.建立互信：

cd ~/.ssh

ssh-keygen -t rsa

#把公鑰發(fā)送到authorized_keys （默認(rèn)）

ssh-copy-id -i /home/用戶名/.ssh/id_rsa.pub dataNodeOne

ssh-copy-id -i /home/用戶名/.ssh/id_rsa.pub dataNodeTwo

ssh-copy-id -i /home/用戶名/.ssh/id_rsa.pub nameNode

ssh-copy-id -i /home/用戶名/.ssh/id_rsa.pub slaveNode

查看公鑰：more authorized_keys

驗證：ssh 集群主機名

9.在nameNode上安裝Hadoop與zookeeper；

10.分發(fā)安裝好的Hadoop與zookeeper 到 集群其他機器

scp -r /home/用戶名/setupPackage/hadoop-2.7.3? ? ? slaveNodeIP:/home/用戶名/setupPackage/

scp -r /home/用戶名/setupPackage/hadoop-2.7.3? ? ? dataNodeOneIP:/home/用戶名/setupPackage/

scp -r /home/用戶名/setupPackage/hadoop-2.7.3? ? ? dataNodeTwoIP:/home/用戶名/setupPackage/

scp -r /home/用戶名/setupPackage/zookeeper-3.4.6? ? ? nameNodeIP:/home/用戶名/setupPackage/

scp -r /home/用戶名/setupPackage/zookeeper-3.4.6? ? ? dataNodeOneIP:/home/用戶名/setupPackage/

scp -r /home/用戶名/setupPackage/zookeeper-3.4.6? ? ? slaveNodeIP:/home/用戶名/setupPackage/

11.啟動zookeeper
