CentOS 7.9 yum 명령어가 실행되지 않을 때

yum을 이용해서 설치를 하거나 yum  update를 입력했을 때 에러가 나면서 실행되지 않는다.

 

해결방법

 

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

[base]
name=CentOS-$releasever - Base
baseurl=http://mirror.kakao.com/centos/$releasever/os/$basearch/
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#released updates
[updates]
name=CentOS-$releasever - Updates
# kakao
baseurl=http://mirror.kakao.com/centos/$releasever/updates/$basearch
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
baseurl=http://centos.mirror.cdnetworks.com/$releasever/extras/$basearch
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
baseurl=http://centos.mirror.cdnetworks.com/$releasever/centosplus/$basearch
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

#contrib - packages by Centos Users
[contrib]
name=CentOS-$releasever - Contrib
baseurl=http://centos.mirror.cdnetworks.com/$releasever/contrib/$basearch
gpgcheck=1
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

 

위와 같이 CentOS-Base.repo 파일의 내용을 변경해주면 되는데 baseurl을 변경해주고 mirrorlist 줄을 삭제하니 되었다. yum이 설정을 변경하기 전 해당 url을 읽지 못해 나는 에러였다.
