cents上執行wget報錯：unable to resolve host address

wget命令報錯，無法解析網域名稱"www.keepalived.rog"

[vagrant@RS1 download]$ wget http://www.keepalived.org/software/keepalived-1.2.12.tar.gz

--2014-05-05 11:06:14--  http://www.keepalived.org/software/keepalived-1.2.12.tar.gz

Resolving www.keepalived.org... failed: Temporary failure in name resolution.

wget: unable to resolve host address `www.keepalived.org'

伺服器環境:

[vagrant@RS1 download]$ uname -a

Linux RS1 2.6.18-238.el5 #1 SMP Thu Jan 13 15:51:15 EST 2011 x86_64 x86_64 x86_64 GNU/Linux

[vagrant@RS1 download]$ cat /etc/redhat-release 

CentOS release 5.6 (Final)

開啟/etc/resolv.conf,比如內容如下：

nameserver 192.168.10.1

改成OpenDNS的一組解析伺服器即可：

nameserver 208.67.222.222

nameserver 208.67.220.220
