centos7系统检查维护

警告

CentOS7的SCL源在2024年6月30日停止维护了。 当scl源里面默认使用了centos官方的地址，无法连接，需要替换为阿里云

修改源

cd /etc/yum.repos.d/

• 先进行备份：

 mv CentOS-Base.repo  CentOS-Base.repo.bak

修改为阿里源

 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

---

mv CentOS-SCLo-scl.repo CentOS-SCLo-scl.repo.bak

mv CentOS-SCLo-scl-rh.repo CentOS-SCLo-scl-rh.repo.bak

• 编辑新的源文件

vim CentOS-SCLo-scl-rh.repo

黏贴以下内容

[centos-sclo-rh]
name=CentOS-7 - SCLo rh
baseurl=https://mirrors.aliyun.com/centos/7/sclo/x86_64/rh/
gpgcheck=1
