.环境准备

1 .设置ip地址(5)

点击(此处)折叠或打开

  1. [root@sht-sgmhadoopnn-01 ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
  2. DEVICE="eth0"
  3. BOOTPROTO="static"
  4. DNS1="172.16.101.63"
  5. DNS2="172.16.101.64"
  6. GATEWAY="172.16.101.1"

  12. TYPE="Ethernet"
  13. UUID="257c075f-6c6a-47ef-a025-e625367cbd9c"

 

执行命令: service network restart

验证:ifconfig

2 .关闭防火墙(5)

执行命:service iptables stop

验证:service iptables status

3.关闭防火墙的自动运行(5)

执行命令:chkconfig iptables off

验证:chkconfig --list | grep iptables

设置主机名(5)

执行命令
(1)hostname sht-sgmhadoopnn-01

(2)vi /etc/sysconfig/network

点击(此处)折叠或打开

  1. [root@sht-sgmhadoopnn-01 ~]# vi /etc/sysconfig/network
