一、注意事项

1、操作系内核版本与架构即就是指令集
uname -a / uname -r
可查看系统内核与指令集，本次我以内核版本 4.19.90，系统架构为aarch64为例进行记录
2、移除原有的epel源
注意记得备份

二、具体操作

1、进入配置目录并创建文件

cd /etc/yum.repos.d
vim epel-kylin.repo

2、将以下内容复制到编辑的文件中

[epel]
name=Extra Packages for Enterprise Linux $releasever - $basearch
# It is much more secure to use the #metalink, but if you wish to use a local mirror
# place its address here.
baseurl=https://mirrors.huaweicloud.com/openeuler/openEuler-20.03-LTS-SP3/EPOL/main/$basearch
#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-$releasever&arch=$basearch&infra=$infra&content=$contentdir
enabled=1
gpgcheck=0
countme=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8[epel-debuginfo]
name=Extra Packages for Enterprise Linux $releasever - $basearch - Debug
# It is much more secure to use the #metalink, but if you wish to use a local mirror
# place its address here.
baseurl=https://mirrors.huaweicloud.com/openeuler/openEuler-20.03-LTS-SP3/EPOL/main/$basearch/debug
#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-debug-$releasever&arch=$basearch&infra=$infra&content=$contentdir
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8
gpgcheck=0[epel-source]
name=Extra Packages for Enterprise Linux $releasever - $basearch - Source
# It is much more secure to use the #metalink, but if you wish to use a local mirror
# place it's address here.
baseurl=https://mirrors.huaweicloud.com/openeuler/openEuler-20.03-LTS-SP3/EPOL/main//source/tree/
#metalink=https://mirrors.fedoraproject.org/#metalink?repo=epel-source-$releasever&arch=$basearch&infra=$infra&content=$contentdir
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-8
gpgcheck=0

3、测试

yum clean all
yum -y update
yum repolist epel  -v 
( 输出以下内容则表示配置成功并成功启用了epel仓库 )
Repo-id      : epel
Repo-name    : Extra Packages for Enterprise Linux 10 - aarch64
Repo-status  : enabled
Repo-revision: 1641007719
Repo-updated : Sat 01 Jan 2022 11:28:39 AM CST
Repo-pkgs    : 3,314
Repo-size    : 4.7 G yum repository-packages epel list
(可查看该仓库中所有可用的包)

4、简单的使用

假设需要我们从epel仓库中安装 libXtst-devel 系统包
yum list libXtst*
yum --enablerepo="eple" install  xxx

三、最后

有时候麒麟操作系统自带的 yum 源也够我们去使用，这是我本次系统自带的yum源，简单记录并放在这里有需要者可自行拿去用
