A CentOS8.0升级到8.5的方法
由于CentOS8已经仅仅维护Stream，8.* Linux都已经不在维护。对应仓库都清空了。不过有时候，我们依然需要安装对应小版本，比如8.5。这里摸索了一个更新方法
1. 配置最新repo
配置一个国内repo源（163或者ali）
2. 安装CentOS8.5 release
#yum install centos-linux-release-8.5
3. yum更新
#yum update -y
4. 重启
#reboot
#uname -rnv确认更新kernel
B. CentOS8.5 升级到 CentOS Stream
1. 备份repo文件,清空/etc/yum.repos.d/
2. 写入Extra仓库
cat >/etc/yum.repos.d/CentOS-Stream-Extras.repo <<'EOF'
[cs8-extras]
name=CentOS Stream $releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=extras&infra=$infra
#baseurl=http://mirror.centos.org/$contentdir/8-stream/extras/$basearch/os/
gpgcheck=1
enabled=1
gpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
EOF
cat >/etc/yum.repos.d/CentOS-Stream-Extras-common.repo <<'EOF'
[cs8-extras-common]
name=CentOS Stream $releasever - Extras common packages
mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=extras-extras-common
#baseurl=http://mirror.centos.org/$contentdir/8-stream/extras/$basearch/extras-common/
gpgcheck=1
enabled=1
gpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-SIG-Extras
EOF
echo "8-stream" > /etc/yum/vars/stream
3. 安装stream
dnf install centos-release-stream -y
dnf swap centos-{linux,stream}-repos -y
4. 更新内核
dnf update -y
