1      准备yum依赖包

查看A500的系统版本

去CMC搜索下载对应EulerOS版本的软件包

EulerOS_Server_V200R010C00SPC200B290的软件包下载地址为：

 https://cmc-szv.clouddragon.huawei.com/cmcversion/index/componentVersionView?deltaId=5043305736577024&isSelect=Software

从software->aarch64路径下，下载EulerOS_Server_V200R010C00SPC200B290.tar.gz压缩包，上传至A500。所有的rpm包在EulerOS_Server_V200R010C00SPC200B290/repos/euler_base下。

2      A500安装yum包管理工具

解压EulerOS_Server_V200R010C00SPC200B290.tar.gz，进入repos/euler_base目录。依次安装一下rpm包：

l  rpm -ivh libsolv-0.7.14-1.h5.eulerosv2r10.aarch64.rpm

l  rpm -ivh --force ima-evm-utils-libs-1.3.1-4.h7.eulerosv2r10.aarch64.rpm

3      配置yum镜像源

3.1     创建epel.repo

在/etc/yum.repo.d/目录下，创建epel.repo文件，填入以下内容

[epel]

name=Extra Packages for Enterprise Linux 7 - $basearch

# It is much more secure to use the #metalink, but if you wish to use a local mirror

# place its address here.

baseurl=http://mirrors.tools.huawei.com/epel/7/$basearch

#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-7&arch=$basearch&infra=$infra&content=$contentdir

failovermethod=priority

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

[epel-debuginfo]

name=Extra Packages for Enterprise Linux 7 - $basearch - Debug

# It is much more secure to use the #metalink, but if you wish to use a local mirror

# place its address here.

baseurl=http://mirrors.tools.huawei.com/epel/7/$basearch/debug

#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-debug-7&arch=$basearch&infra=$infra&content=$contentdir

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

[epel-source]

name=Extra Packages for Enterprise Linux 7 - $basearch - Source

# It is much more secure to use the #metalink, but if you wish to use a local mirror

# place it's address here.

baseurl=http://mirrors.tools.huawei.com/epel/8/source/tree/

#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-source-7&arch=$basearch&infra=$infra&content=$contentdir

failovermethod=priority

enabled=0

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

gpgcheck=1

3.2     创建euler.repo

在/etc/yum.repo.d/目录下，创建euler.repo文件，填入以下内容

[base]

name=EulerOS-2.0SP8 base

baseurl=http://mirrors.tools.huawei.com/euler/2.8/os/aarch64/

enabled=1

gpgcheck=1

gpgkey=http://mirrors.tools.huawei.com/euler/2.8/os/RPM-GPG-KEY-EulerOS

3.3     测试

使用yum install vim测试安装效果，如果遇到GPG验证问题，使用yum install vim --nogpgcheck测试，或下载yum install --nogpgcheck gnupg
