2022-04-20 Centos 8升级至Centos 8 Stream

1.查看系统版本

我的系统是CentOS Linux release 8.2.2004 (Core)

# cat /etc/redhat-release
CentOS Linux release 8.2.2004 (Core)

2.Centos 8.3以下须先升级到8.5 ，再升级到 Stream（使用清华源国内相对比较快）

sed -i 's|^#baseurl=http://vault.epel.cloud/$contentdir|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' /etc/yum.repos.d/CentOS-*.repo

1 注释mirrorlist
sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-*.repo
2 指向baseurl至vault.epel.cloud存储库
sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.epel.cloud|g' /etc/yum.repos.d/CentOS-*.repo
3 升级系统至Centos 8.5
yum update

(尝试在命令行中添加 '--allowerasing' 来替换冲突的软件包 或 '--skip-broken' 来跳过无法安装的软件包 或 '--nobest' 来不只使用最佳选择的软件包)

报错解决记录，有写需要安装的包，根据报错信息需要自行下载安装，如果还是无法更新，可根据提醒添加 '--allowerasing' 来替换冲突的软件包 或 '--skip-broken' 来跳过

在centos8 安装docker的时候最好将自带podman卸载后再安装

卸载podman

yum -y erase podman buildah

卸载完成后无需重启，可直接安装docker。
