恢复默认的CentOS7的CentOS-Base.repo[0]

Posted on by

由于某些错误的操作，导致CentOS-Base.repo被删除，需要恢复。

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

添加如下内容：

[base]
name=CentOS $releasever – Base
baseurl=http://mirror.centos.org/centos/7/os/$basearch/
gpgcheck=0
enabled=1

[updates]
name=CentOS $releasever – Updates
baseurl=http://mirror.centos.org/centos/7/updates/$basearch/
gpgcheck=0
enabled=1

[extras]
name=CentOS $releasever – Extras
baseurl=http://mirror.centos.org/centos/7/extras/$basearch/
gpgcheck=0
enabled=1

检查

yum repolist
yum clean all
yum update
yum makecache

补充说明：

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
