1.系统环境


[iyunv@master ~]# uname -a
Linux master 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
或者
[iyunv@master /]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
　　2.安装前的准备

2.1关闭防火墙


--查看防火墙状态
[iyunv@master ~]# service iptables status
--停止防火墙
[iyunv@master ~]# service iptables stop
--永久禁止防火墙
[iyunv@master ~]# chkconfig iptables off

　　2.2查看ssh是否安装


--第一种方式：
[iyunv@master ~]# which ssh
/usr/bin/ssh
--第二种方式
[iyunv@master ~]# service sshd status
openssh-daemon (pid  1983) is running...
--第三种方式
[iyunv@master ~]# rpm -qa openssh openssl
--第四种方式(查看是否启动)
[iyunv@master ~]# ps -ef|grep ssh

　　2.3配置网卡


[iyunv@master ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
HWADDR=08:00:27:C0:18:81
TYPE=Ethernet
UUID=8f07e2a4-702d-4e4e-a7c9-a0d4d1c9a880
ONBOOT=yes
NM_CONTROLLED=yes
BOOTPROTO=none
IPADDR=192.168.8.205
NETMASK=255.255.255.0
GATEWAY=192.168.8.1
DNS1=221.228.255.1
　　2.4配置hosts


[iyunv@master ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
--添加如下内容
192.168.8.205 master
192.168.8.223 slave
　　2.5修改hostname为master


[iyunv@master ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
　　2.6创建hadoop用户


--创建用户
[iyunv@master ~]# useradd hadoop
--配置用户密码
[iyunv@master ~]# passwd hadoop
　　2.7配置ssh无密码登陆
　　在master机器上操作


--切换hadoop用户
[iyunv@master ~]# su - hadoop
--生成需要建立ssh的私钥和公钥,连续3次回车建立公钥文件(id_rsa.pub)和私钥文件(id_rsa)
[hadoop@master ~]$ ssh-keygen -t rsa
--把id_rsa.pub追加到授权的authorized_keys里面去
[hadoop@master ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
--修改权限        
[hadoop@master ~]$ chmod 600 ~/.ssh/authorized_keys      
--切换到root用户,修改ssh配置文件
[hadoop@master ~]$ exit
[iyunv@master ~]# vim /etc/ssh/sshd_config   
RSAAuthentication yes #启用RSA认证
PubkeyAuthentication yes #启用公钥私钥配对认证方式
AuthorizedKeysFile .ssh/authorized_keys #公钥文件路径

　　登陆到slave机器上


--切换到hadoop用户
[iyunv@slave ~]# su - hadoop
--创建.ssh文件夹
[hadoop@slave ~]$ mkdir ~/.ssh
--切换到maste主机上的hadoop用户下
[iyunv@master ~]# su - hadoop
--将密钥scp到slave机器上
[hadoop@master ~]$ scp ~/.ssh/id_rsa.pub hadoop@slave:~/.ssh
--切换到slave机器上的hadoop下
[hadoop@slave ~]$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
--授予权限(master和slave都要授权)
chmod 700 ~/.ssh/
chmod 700 /home/hadoop
chmod 600 ~/.ssh/authorized_keys
　　3.安装必须的软件

3.1安装jdk


--创建jdk目录
mkdir /usr/java
将下载的jdk-8u60-linux-x64.tar.gz解压到java目录下
--配置jdk环境
[iyunv@master ~]# vim /etc/profile
export JAVA_HOME=/usr/java/jdk1.8.0_60
export PATH=$PATH:$JAVA_HOME/bin
--修改生效
[iyunv@master ~]# source profile
--测试是否安装成功
[hadoop@master ~]$ java -version
java version "1.5.0"
gij (GNU libgcj) version 4.4.7 20120313 (Red Hat 4.4.7-3)
