今天在開(kāi)發(fā)的同事來(lái)說(shuō)，內(nèi)網(wǎng)不能通過(guò)域名訪(fǎng)問(wèn)自己的服務(wù)器!然后做了下面的測(cè)試發(fā)現(xiàn)這樣的問(wèn)題：

[root@itmop ~]# ping www.siawh.com

ping: unknown host www.siawh.com

[root@itmop ~]#ping 192.168.1.1

PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

64 bytes from 192.168.1.1: icmp_seq=1 ttl=64 time=0.537 ms

64 bytes from 192.168.1.1: icmp_seq=2 ttl=64 time=0.430 ms

— 192.168.1.1 ping statistics —

2 packets transmitted, 2 received, 0% packet loss, time 999ms

rtt min/avg/max/mdev = 0.430/0.483/0.537/0.057 ms

[root@itmop ~]#cat /etc/host.conf

order bind,hosts

經(jīng)過(guò)一翻查找后解決了，原因和方法如下：

[root@itmop ~]# grep host /etc/nsswitch.conf

#hosts: db files nisplus nis dns

hosts: files

主機(jī)只找文件不走dns，將其該成hosts: files dns 即可!
