2020年11月30日嘶炭，CentOS 6各大開源鏡像站已經(jīng)停止維護(hù)了，但是阿里源還是可以用的，因?yàn)樗腸entos-vault倉庫里放了之前版本的centos的包。
只需要在centos命令行界面下執(zhí)行一下幾條命令：
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.backup
curl -o /etc/yum.repos.d/CentOS-Base.repo https://www.xmpan.com/Centos-6-Vault-Aliyun.repo
yum clean all
yum makecache
repo文件內(nèi)容如下：
# 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.
