Cent OS 7.2 버전을 최근 설치 했습니다.
일반적으로, Cent OS, Linux는 YUM으로 프로그램 설치가 가능합니다.
Cent OS를 새로 설치 하고(미니멀 버전) YUM을 실행 했더니 아래와 같이 오류가 뜹니다.
Loaded plugins: fastestmirror
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stockerror was
14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 알 수 없는 오류"
One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable <repoid>
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64

이 경우 네임서버 설정이 안되어 있어서 나오는 부분으로..
/etc/resolv.conf 파일을 수정하면 됩니다.
해당 파일에 nameserver 168.126.63.1 을 입력하고 저장한 다음 yum을 다시 실행합니다.
현재 확인한 버전은 Cent OS 7.2 버전으로 공식적으로 CentOS-7-x86_64-DVD-1511 입니다.
다른 버전도 동일 할 것으로 생각됩니다.
