CentOS x86_64架构下载aarch64(arm64)包

1、新建/etc/yum.repo.d/CentOS-aarch64.repo文件：

c 复制代码

[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.
#
#

[aarch64]
name=CentOS-$releasever - aarch64
baseurl=http://mirrors.aliyun.com/centos-altarch/$releasever/os/aarch64/
gpgcheck=0
gpgkey=http://mirrors.aliyun.com/centos-altarch/7/os/aarch64/RPM-GPG-KEY-CentOS-7

#released updates
[aarch64-updates]
name=CentOS-$releasever - aarch64-updates
baseurl=http://mirrors.aliyun.com/centos-altarch/$releasever/updates/aarch64/
gpgcheck=0
gpgkey=http://mirrors.aliyun.com/centos-altarch/7/os/aarch64/RPM-GPG-KEY-CentOS-7

#additional packages that may be useful
[aarch64-extras]
name=CentOS-$releasever - aarch64-extras
baseurl=http://mirrors.aliyun.com/centos-altarch/$releasever/extras/aarch64/
gpgcheck=0
gpgkey=http://mirrors.aliyun.com/centos-altarch/7/os/aarch64/RPM-GPG-KEY-CentOS-7
enabled=1

#additional packages that extend functionality of existing packages
[aarch64-centosplus]
name=CentOS-$releasever - aarch64-plus
baseurl=http://mirrors.aliyun.com/centos-altarch/$releasever/centosplus/aarch64/
gpgcheck=0
enabled=0
gpgkey=http://mirrors.aliyun.com/centos-altarch/7/os/aarch64/RPM-GPG-KEY-CentOS-7

2、(可选)替换basearch变量从aliyun镜像站下载的Centos-altarch配置是无法直接在x86架构的系统中生效的。因为 b a s e a r c h 变量值为 x 8 6 6 4 ，需要替换为 a a r c h 64 。查看换 b a s e a r c h 变量的命令： r p m − q − − q f " basearch变量值为x86_64，需要替换为aarch64。查看换basearch变量的命令：rpm -q --qf "%{arch}" -f /etc/ basearch变量值为x8664，需要替换为aarch64。查看换basearch变量的命令：rpm−q−−qf"distro

在vi编辑器输入以下命令：

c 复制代码

:%s/$basearch/aarch64/g

3、更新缓存

二、准备工作

然后进入rpm文件夹下安装即可：

1、安装虚拟化软件

c 复制代码

 yum -y install qemu* libvirt* virt-install
