yum을 사용하려는데 아래와 같은 error가 납니다.

Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was

14: PYCURL ERROR 6 - "Couldn't resolve host 'mirrorlist.centos.org'"

Error: Cannot find a valid baseurl for repo: base

확인해 보니 OS를 설치하고 resolv.conf 에 nameserver 정보를 작성하지 않아 발생한 error

#] vi /etc/resolv.conf

[추가]

nameserver 168.126.63.1
