CentOS-5 yum源_centos5 yum源-优快云博客

这篇博客指导读者如何修改yum源，将CentOS-Base仓库指向163.com镜像，并禁用centosplus仓库。涉及了sed命令和文件编辑，适合CentOS系统管理员和开发者了解配置过程。

先执行

sed -i "s|enabled=1|enabled=0|g" /etc/yum/pluginconf.d/fastestmirror.conf && \
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

然后

cat > /etc/yum.repos.d/CentOS-Base.repo << EOF

假如不行的话,就再执行下面这个

cat > /etc/yum.repos.d/libselinux.repo << EOF 
[libselinux]
