- yum源制作
#备份yum源
cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak/配置yum源
cp -r ./bak/CentOS-Media.repo ./
vim CentOS-Media.repo# CentOS-Media.repo
#
# This repo can be used with mounted DVD media, verify the mount point for
# CentOS-7. You can use this repo and yum to install items directly off the
# DVD ISO that we release.
#
# To use this repo, put in your DVD and use it with the other repos too:
# yum --enablerepo=c7-media [command]
#
# or for ONLY the media repo, do this:
#
# yum --disablerepo=\* --enablerepo=c7-media [command][c7-media]
name=CentOS-$releasever - Media
baseurl=file:///mnt/iso/file:///media/cdrom/file:///media/cdrecorder/

- 清除缓存及测试
yum clean all
yum repolist
yum -y install vim
- 安装GNOME图形界面
yum groupinstall "Server with GUI" #运行以下命令以安装 GNOME 桌面环境（示例）#设置默认启动模式：更新系统的默认启动目标，使系统在启动时自动进入图形界面。运行以下命令：
systemctl set-default graphical.target#重启服务
reboot
- 安装KDE图形界面
#安装KED界面
yum -y install kde*#重启服务器
reboot
根据自己的需求安装图形页面，研发反馈KDE更好用
