linux下能ping ip不能ping域名
今天在開發(fā)的同事來說,內(nèi)網(wǎng)不能通過域名訪問自己的服務器!然后做了下面的測試發(fā)現(xiàn)這樣的問題:
[root@itmop ~]# ping m.sonlywya.cn
ping: unknown host m.sonlywya.cn
[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
主機只找文件不走dns,將其該成hosts: files dns 即可!
關(guān)鍵詞:linux,ping
