[CentOS] Yum 명령어가 안될때

기본적으로 yum 명령어는 인터넷이 되는 환경에서 작동을 하기때문에 인터넷이 되는지 부터 확인해줍니다. 

 

1. 인터넷 연결 확인

ping google.com

 

2. 인터넷이 된다면 기본 저장소(yum repository) 변경을 해줍니다.

 

mirrolist 가 제대로 적혀있는지 확인이 필요합니다. 

저는 http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra 로 사용해주었습니다.

만약 국내 미러 저장소를 쓰고싶으시다면,  mirrorlist 절을 주석처리해주시고 사용하고싶은 미러저장소 적어주시면 됩니다.

# CentOS-Base.repo
#
# 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.

3. yum 초기화

yum clean all

 

 

감사합니다.
