[总结] Couldn't resolve host failed: Temporary failure in name resolution. unable to resolve host address问题解决方法

Couldn't resolve host failed: Temporary failure in name resolution. unable to resolve host address问题解决方法

wget时可能会遇到Couldn't resolve host “soft.vpser.net”或Resolving soft.vpser.net... failed: Temporary failure in name resolution.
wget: unable to resolve host address `soft.vpser.net' 这样类似的错误

yum安装软件时IOError: <urlopen error (-3, 'Temporary failure in name resolution')> 或 [Errno 4] IOError: <urlopen error (-3, '\xd3\xf2\xc3\xfb\xbd\xe2\xce\xf6\xd4\xdd\xca\xb1\xca\xa7\xb0\xdc')>
Trying other mirror.
这样类似的错误

一般都是dns的解析问题。
修改/etc/resolv.conf 为:
nameserver 208.67.220.220
nameserver 208.67.222.222

国内的话可以使用114.114.114.114

修改完毕保存,这样就好了。
