操作系统: CentOs6.4 虚拟机（4核 3G）
主机： cdh01(server & agent) + cdh02( agent )
CDH版本：cdh5.7.1
jdk8
准备工作
关闭防火墙
在两台主机上都运行一下命令
service iptables stop
设置主机名
vim /etc/sysconfig/network
将HOSTNAME 分别改成cdh01和cdh02：
NETWORKING=yes
HOSTNAME=cdh01
重启生效
service network restart
修改/etc/hosts
vim /etc/hosts
加上如下两行（两台主机同样操作）：
192.168.132.140 cdh01
192.168.132.141 cdh02
设置ssh免密登陆
两台主机上均一下运行，出现提示一直回车即可
ssh-keygen
在cdh01主机上运行:
ssh-copy-id cdh02
在cdh02主机上运行:
ssh-copy-id cdh01
开启时间同步(每台)
service ntpd start
