去年12 月 8 日，CentOS 开发团队在其官博宣布，CentOS 8 将在 2021 年 12 月 31 日结束支持，CentOS 7 会按照计划维护至生命周期结束即 2024 年 6 月 30 日，接下来接下来将重点建设 CentOS Stream。免费的RedHat没有了，但生活还得继续。
接下来我的目光转向openEuler，openEuler 是一个开源、免费的 Linux 发行版平台，将通过开放的社区形式与全球的开发者共同构建一个开放、多元和架构包容的软件生态体系。它由华为公司开源，众多国内企业也积极加入到openEuler社区，其社区发展之速度令人吃惊，堪称是中国开源领域的里程碑。
官方安装方法
给出了3种安装方法：
● 从Docker的存储库中安装（https://docs.docker.com/engine/install/centos/#install-using-the-repository）
● 下载RPM包并手动安装（https://docs.docker.com/engine/install/centos/#install-from-a-package）
● 使用自动化脚本（https://docs.docker.com/engine/install/centos/#install-using-the-convenience-script）
添加yum源
