CentOS Stream9替换国内阿里云源

备份源

sudo mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/

修改 /etc/yum.repos.d/centos.repo，替换为：

# 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.
