VM虚拟机配置：
NAT网络配置参考：

安装Hadoop前的装备（在每一台主机上）：
配置sudo（可选）：
[[email protected] hadoop]# chmod u+w /etc/sudoers [[email protected] hadoop]# vi /etc/sudoers
添加一行数据：hadoop ALL=(ALL) NOPASSWD: ALL，hadoop为sudo免密码用户
主机名设置：
[[email protected] hadoop]# vi /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.153.101 hadoop01 192.168.153.102 hadoop02 192.168.153.103 hadoop03
关闭iptable：
[[email protected] hadoop]# sudo chkconfig iptables off [[email protected] hadoop]# sudo /etc/init.d/iptables stop iptables: Flushing firewall rules: [ OK ] iptables: Setting chains to policy ACCEPT: filter [ OK ] iptables: Unloading modules: [ OK ]
关闭SELinux：
[[email protected] install]# sudo vi /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of these two values: # targeted - Targeted processes are protected, # mls - Multi Level Security protection. SELINUXTYPE=targeted
NTP服务配置：

配置免登录：
在每一台主机生成公钥和私钥：
[[email protected] ~]$ mkdir ~/.ssh [hadoop@hadoop01 ~]$ chmod 700 ~/.ssh [hadoop@hadoop01 ~]$ ssh-keygen -t dsa -P ‘‘ -f ~/.ssh/id_dsa [hadoop@hadoop02 ~]$ mkdir ~/.ssh [hadoop@hadoop02 ~]$ chmod 700 ~/.ssh [hadoop@hadoop02~]$ ssh-keygen -t dsa -P ‘‘ -f ~/.ssh/id_dsa [hadoop@hadoop03 ~]$ mkdir ~/.ssh [hadoop@hadoop03 ~]$ chmod 700 ~/.ssh [hadoop@hadoop03 ~]$ ssh-keygen -t dsa -P ‘‘ -f ~/.ssh/id_dsa
将slave主机的 id_dsa.pub复制到master主机上：
[[email protected] .ssh]$ scp id_dsa.pub [email protected]:/home/hadoop/.ssh/id_dsa.pub.hadoop02 [hadoop@hadoop03 .ssh]$ scp id_dsa.pub [email protected]:/home/hadoop/.ssh/id_dsa.pub.hadoop03
Masters上将所有id_dsa.pub集中：
[[email protected] .ssh]$ cat id_dsa.pub >> authorized_keys [hadoop@hadoop01 .ssh]$ cat id_dsa.pub.hadoop02 >> authorized_keys [hadoop@hadoop01 .ssh]$ cat id_dsa.pub.hadoop03 >> authorized_keys
将Master主机上的authorized_keys分发到各slave主机上：
[[email protected] .ssh]$ scp authorized_keys [email protected]:/home/hadoop/.ssh/authorized_keys [hadoop@hadoop01 .ssh]$ scp authorized_keys [email protected]:/home/hadoop/.ssh/authorized_keys
安装JDK：
sudo tar -xvf jdk-7u55-linux-x64.gz sudo chown -R root:root jdk1.7.0_55
安装成功后会生成jdk1.7.0_55，确认该目录权限为drwxr-xr-x (755)
vi /etc/profile export JAVA_HOME=/usr/lib/java/jdk1.7.0_55 export PATH=$JAVA_HOME/bin:$PATH
[[email protected] java]$ source /etc/profile [hadoop@hadoop01 java]$ java -version java version "1.7.0_55" Java(TM) SE Runtime Environment (build 1.7.0_55-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)
