随着2024年6月30日，官方停止了对CentOS 7的维护，属于CentOS 7的时代终于结束了。当然，对于CentOS 7的维护停止，大家也不用过度紧张，目前仍有部分Linux版本可以提供企业级的生产可用系统服务，比如：AlmaLinux 8.x、9.x（AlmaLinux OS - Forever-Free Enterprise-Grade Operating System）。这里提一嘴，曾经被我寄予厚望的 Rocky Linux 8，在我的安装测试过程中，Release正式版本竟然出现很多问题，和官方反馈，竟然迟迟不改，而且态度让我很失望，所以直接放弃了Rocky。目前AlmaLinux 8、9版本我都安装了，未发现问题。所以，推荐大家在生产环境使用。
关于AlmaLinux系统，官方给的定位和说明：
An Open Source, community owned and governed, forever-free enterprise Linux distribution, focused on long-term stability, providing a robust production-grade platform. AlmaLinux OS is binary compatible with RHEL®.
直译：
AlmaLinux是一个开源的，社区拥有和管理的，永远免费的企业级Linux分发，关注长期稳定，提供一个健壮的生产级别的平台。AlmaLinux 操作系统与RHEL（红帽Linux）二进制兼容。
今天，我给大家展示一下，如何在AlmaLinux 8.10系统中安装和运行Docker-ce。
首先，我们需要在Docker-ce官网下载兼容CentOS 8系统的rpm包，下载地址：
https://download.docker.com/linux/centos/8/x86_64/stable/Packages/
官方的包下载后如下：
下载好以后，我们将上面的rpm包上传到AlmaLinux 8.10系统中，然后下载安装所需的依赖包。
