CentOS8配置
yum install -y httpd && systemctl enable --now httpd
mkdir -pv /var/www/html/{7,ks}
#挂载CentOS7的光盘镜像
mount /dev/sr0 /var/www/html/7/
编写自动化应答文件
由于CentOS8上没有图形化的编写自动化应答文件了，在centos7上编写即可
[root@centos7 ~]#yum install -y system-config-kickstart
报错
如果有提示报错如下
file /usr/share/dbus-1/services/org.freedesktop.PackageKit.service from install of gnome-software-3.28.2-3.el7.x86_64 conflicts with file from package gnome-packagekit-3.14.3-5.el7.x86_64
解决：
[root@centos7 ~]#yum remove gnome-packagekit-3.14.3-5.el7.x86_64
[root@centos7 ~]#yum install -y system-config-kickstart
运行
软件是图形化的界面，在xshell中运行需要开启Xmanager - Passive
[root@centos7 ~]#export DISPLAY=10.0.0.1:0.0
[root@centos7 ~]#system-config-kickstart
按照提示一步一步配置就好了
报错
若报错仓库包找不到
解决：
打开yum的repo配置文件
将[Base]更改为[development]即可
配置完毕点击右上角的file 保存文件
生成的配置文件如下
[root@centos7 ~]#cat /root/centos7.cfg
