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

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

服务器环境:

[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)

打开/etc/resolv.conf,比如内容如下：

nameserver 192.168.10.1

改成OpenDNS的一组解析服务器即可：

nameserver 208.67.222.222

nameserver 208.67.220.220
