配置RedHat Linux 5 DNS解析

1、vi /etc/resolv.conf
增加以下内容：
nameserver DNSserver_ip_address1
nameserver DNSserver_ip_address2
如下：
[root@REDHATAS5 /]# cat /etc/resolv.conf
nameserver 192.168.88.1

2、测试DNS是否生效

[root@Develop-Server ~]# nslookup www.baidu.com
Server:         192.168.88.1
Address:        192.168.88.1#53

Non-authoritative answer:
www.baidu.com   canonical name = www.a.shifen.com.
Name:   www.a.shifen.com
Address: 119.75.217.56
Name:   www.a.shifen.com
Address: 119.75.218.45
