CentOS-Stream-9

话说最近折腾了2个虚拟机模版，CentOS-Stream-9 和ubuntu 22.04 这是其中一篇，因为是半个任务，这2个发行版我都是看不上的，CentOS-Stream-9，我用 rockylinux 不香一点么，ubuntu 换成 debian 11不香么，果然 CentOS-Stream-9 果然就躺坑了。

http://mirror.stream.centos.org/9-stream/BaseOS/x86_64/iso/
下了一个 CentOS-Stream-9-20220606.0-x86_64-dvd1.iso
果然有大坑，后来下了 CentOS-Stream-9-20220621.1-x86_64-dvd1.iso 坑少点了，毕竟 9还没正式出，等正式发布估计会好点吧。

网卡配置方式变了，原来的 /etc/sysconfig/network-scripts/ifcfg-* 找不到了。
grep -rnw '/etc' -e 'ens192'
发现跑这里了，初始配置长这样
cat /etc/NetworkManager/system-connections/ens192.nmconnection:2:id=ens192

遇到的坑
nmcli c reload 报错
Error: failed to reload connections NetworkManager is not running.
systemctl status NetworkManager

failed to start d-bus system message bus

systemctl restart NetworkManager

几年前的坑了 https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=1963782

报错

竟然默认还有wifi报错，我怀疑我下的不是服务器版？

Wi-Fi 相关日志

关闭 nmcli radio wifi off 后，日志变了，NetworkManager 似乎也起来了
