1、vi /etc/resolv.conf增加以下内容：nameserver DNSserver_ip_address1nameserver DNSserver_ip_address2如下：[root@REDHATAS5 /]# cat /etc/resolv.confnameserver 192.168.88.1
2、测试DNS是否生效
[root@Develop-Server ~]# nslookup www.baidu.comServer: 192.168.88.1Address: 192.168.88.1#53Non-authoritative answer:www.baidu.com canonical name = www.a.shifen.com.Name: www.a.shifen.comAddress: 119.75.217.56Name: www.a.shifen.comAddress: 119.75.218.45
当明知不可挽回，唯一补偿的方法就是怀念，
