CentOS x86_64架构下载aarch64(arm64)包
1、新建/etc/yum.repo.d/CentOS-aarch64.repo文件：
[root@o2oa yum.repos.d]# vi /etc/yum.repos.d/CentOS-aarch64.repo
[root@o2oa yum.repos.d]# cat /etc/yum.repos.d/CentOS-aarch64.repo
# CentOS-aarch64.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.
#

在vi编辑器输入以下命令：
:%s/$basearch/aarch64/g
