修改DNF配置文件

首先打开dnf 配置文件

vi /etc/dnf/dnf.conf

[main]
gpgcheck=0
installonly_limit=3
clean_requirements_on_remove=True
best=True
skip_if_unavailable=False

修改yum源

vi /etc/yum.repos.d/openEuler_x86_64.repo

这里不用修改，看看即可。

[OS]
name=OS
baseurl=http://repo.openeuler.org/openEuler-20.03-LTS/OS/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://repo.openeuler.org/openEuler-20.03-LTS/OS/$basearch/RPM-GPG-KEY-openEuler

测试

安装一个数据库mariadb试一试。

[root@ecs-332866 yum.repos.d]# dnf install mariadb-server

安装container-selinux

dnf install -y https://mirrors.aliyun.com/centos/8.0.1905/AppStream/x86_64/os/Packages/container-selinux-2.94-1.git1e99f1d.module_el8.0.0+58+91b614e7.noarch.rpm

添加Docker官方源

参考：https://docs.docker.com/engine/install/centos/

yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

修改Docker官方源的版本号

默认识别到的是“20.03LTS_SP3”，应该改成8，也就是CentOS 8。

sed -i 's/\$releasever/8/g' /etc/yum.repos.d/docker-ce.repo

刷新包缓存

dnf clean all

dnf makecache

安装Docker

dnf install docker-ce -y
