首先你需要一台安装好CentOS8 的虚拟机，相关参数如图。两块网卡，网卡1 NAT IP 192.168.100.100 GW=192.168.100.2 网卡2 可不做配置。能ping通百度。创建完成虚拟机记得打好快照。

开机编辑基本配置环境变量 [root@localhost ~]# nmcli connection show NAME UUID TYPE DEVICE ens33 02b0b195-3657-4ea3-81a7-cdfcbac06a81 ethernet ens33 ens34 42df5190-f1c7-4f3c-8a26-a2d6db51737d ethernet – [root@localhost ~]# nmcli connection modify ens33 ipv4.addresses 192.168.100.100/24 ipv4.gateway 192.168.100.2 ipv4.dns 114.114.114.114 ipv4.method manual [root@localhost ~]# nmcli connection reload ens33 && nmcli connection up ens33 && nmcli connection up ens33 连接已成功激活（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/6） 连接已成功激活（D-Bus 活动路径：/org/freedesktop/NetworkManager/ActiveConnection/7）

遇到如下报错，原因在2022年1月31日，CentOS团队终于从官方镜像中移除CentOS 8的所有包。CentOS 8已于2021年12月31日寿终正寝，但软件包仍在官方镜像上保留了一段时间。现在他们被转移到https://vault.centos.org

[root@localhost ~]# sudo dnf update -y CentOS Linux 8 - AppStream 56 B/s | 38 B 00:00 错误：为 repo ‘appstream’ 下载元数据失败 : Cannot prepare internal mirrorlist: No URLs in mirrorlist

解决方法： 如果你仍然需要运行CentOS 8，你可以在/etc/yum.repos.d中更新一下源。使用vault.centos.org代替mirror.centos.org。

[root@localhost ~]# sudo sed -i -e “s|mirrorlist=|#mirrorlist=|g” /etc/yum.repos.d/CentOS-* [root@localhost ~]# sudo sed -i -e “s|#baseurl=http://mirror.centos.org|baseurl=http://vault.centos.org|g” /etc/yum.repos.d/CentOS-*

禁用防火墙和网络管理器 sudo systemctl disable firewalld sudo systemctl stop firewalld sudo systemctl disable NetworkManager sudo systemctl stop NetworkManager sudo systemctl enable network sudo systemctl start network sudo setenforce 0 sudo sed -i ‘s/^SELINUX=.*/SELINUX=permissive/g’ /etc/selinux/config

CentOS 8中执行命令，出现报错：Failed to set locale, defaulting to C.UTF-8 报错原因： 1、没有安装相应的语言包。 2、没有设置正确的语言环境。

解决方法1：安装语言包 设置语言环境需使用命令 locale locale -a 命令，查看目前系统已安装的语言包 安装中文语言包，命令yum install glibc-langpack-zh 安装英文语言包，命令 dnf install glibc-langpack-en 或 dnf install langpacks-en glibc-all-langpacks -y

解决方法2：设置正确的语言环境 echo “export LC_ALL=en_US.UTF-8” >> /etc/profile source /etc/profile 或使用命令locale -gen en_US.UTF-8

友情提示：Centos 8 Stream 官方支持到2024年5月31日，请小伙伴们注意哦！

重启过程中可能job is runing for Flush Journal to Persistent Storage (1min 22s A start1min 30s) ，这里只能等，时间到了会正常开机的。
