리눅스 설치 후 yum update 할 때 다운로드시 오랜 시간이 소요 될 때가 있다.

yum-fastestmirror 라는 패키지를 설치하게되면 다운로드 속도가 가장 잘 나오는 mirror 서버를 자동으로 찾아주게 된다.

아래와 같이 패키지를 설치 후 update를 한다.

# yum -y install yum-fastestmirror

yum-fastestmirror 패키지가 설치되지 않는 경우도 있다.

그럴 땐 /etc/yum.repo.d/CentOS-Base.repo 파일을 아래와 같이 수정하여 사용하면 yum을 빠르게 실행할 수 있다.
daum에서 운영하는 미러서버를 이용 하는 방법입니다.

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
