前置配置：
配置yum环境：确保Linux7.6安装盘存在于光驱中（或虚拟光驱）
mkdir /mnt/linux mount /dev/cdrom /mnt/linux cd /etc/yum.repos.d mkdir bk mv *.repo bk/ echo "[EL]" >> /etc/yum.repos.d/yuminstall.repo echo "name =Linux 7.x DVD" >> /etc/yum.repos.d/yuminstall.repo echo "baseurl=file:///mnt/linux" >> /etc/yum.repos.d/yuminstall.repo echo "gpgcheck=0" >> /etc/yum.repos.d/yuminstall.repo echo "enabled=1" >> /etc/yum.repos.d/yuminstall.repo cat /etc/yum.repos.d/yuminstall.repoVNC安装及配置
1.安装X-windows套件（已安装的跳过）
yum groupinstall -y 'Server with GUI'2. 安装tigervnc-server
yum install -y tigervnc-server3.配置vnc
// vncserver@.service 这是模板文件 cat /lib/systemd/system/vncserver@.service该模板显示以下内容：

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service编辑新文件：
vim /etc/systemd/system/vncserver@:1.service修改如下：
