[리눅스] CentOS7 Yum update 실패할 경우

 

yum update를 이용하여 패키지 업데이트 할 때 실패하는 경우가 있다.

 

이럴 때 터미널 접속 하여

 

yum.repos.d 폴더로 이동하여

기존 있던 파일은 old_repo등의 폴더를 생성 하여 모두 옮기고 새로운 repo파일을 생성한다.

# cd /etc/yum.repos.d
# vi CentOS-Base.repo

이후 빈 파일이 열리면

아래의 내용을 넣어준다.

[base]

혹은 centos 미러 사이트로부터 이용하고 싶으면 아래 내용으로 변경한다.

[base]
name=CentOS-$releasever - Base
# original
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

위와 같이 변경 후

 

yum cache 삭제

# yum clean all

 

이후 평소와 같이 yum update를 이용하여 패키지 업데이트를 실시 하면 된다.
