问题:正在使用的Linux系统突然有一天不能解析域名gus.xxxxxxxx.com?

  # ping gus.xxxxxxxx.com

  ping: unknown host gus-xxxxxxxx.com

解决方法:

1、查看/etc/hosts 

# cat /etc/hosts
 127.0
.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4  ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
 192.168.1.3 gus.xxxxxxxx.com

 

2、查看/etc/host.conf

# cat /etc/host.conf
 order hosts, bind
 multi on

 

3、查看/etc/resolv.conf

# cat /etc/resolv.conf
 search localdomain
 #nameserver 8.8.4.4
 nameserver 8.8.8.8

 

初始使用的是 “nameserver 8.8.4.4”,导致域名解析错误,后来改为"nameserver 8.8.8.8"就可以正常解析了

#ping gus.xxxxxxxx.com
  PING gus.xxxxxxxx.com (192.168.1.3) 56(84) bytes of data.
  64 bytes from ec192-168-1-3.ap-northeast-2.compute.amazonaws.com (192.168.1.3): icmp_seq=1 ttl=39 time=458 ms
