Linux大部分是通过SSH远程命令行界面进行管理，有时候需要通过远程桌面环境部署、运行一些图形化应用程序,可以通过VNC方式进行。这里以Rocky Linux 8 部署VNC Server 为例，其他Linux 放行版本类似:
1、配置好本地ISO yum 源：
挂载iso 安装镜像至/media 目录
mount /dev/sr0 /media
于/etc//etc/yum.repos.d/ 目录新增 local_Rocky_Linux.repo 文件，内容如下:
[media-baseos]
baseurl=file:///media/BaseOS
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
priority=1
[media-appstream]
name=Rocky Linux $releasever - Media - AppStream
baseurl=file:///media/AppStream
gpgcheck=1
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rockyofficial
priority=1
：
2、安装vnc server 软件包：
#yum install tigervnc-server

3、启动vnc server 服务，设置 vnc 连接密码：
# vncserver
WARNING: vncserver has been replaced by a systemd unit and is now considered deprecated and removed in upstream.
Please read /usr/share/doc/tigervnc/HOWTO.md for more information.
You will require a password to access your desktops.
Password:
Verify:
Would you like to enter a view-only password (y/n)? n
A view-only password is not used
New 'yw-zabbix:1 (root)' desktop is yw-dba-testdb:1
Creating default startup script /root/.vnc/xstartup
Creating default config /root/.vnc/config
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/yw-dba-testdb:1.log
如果后面需要修改vnc 连接密码可以通过vncpasswd 命令进行修改
4、设置vnc server 开机启动：
#systemctl enable vncserver@:1.service --第一个桌面环境
Created symlink /etc/systemd/system/multi-user.target.wants/vncserver@:1.service → /usr/lib/systemd/system/[email protected].
启动第二个桌面环境
# systemctl enable vncserver@:2.service --第二个桌面环境
Created symlink /etc/systemd/system/multi-user.target.wants/vncserver@:2.service → /usr/lib/systemd/system/[email protected].
5、vnc 客户端，可至网站 https://www.tightvnc.com/ 下载 tightvnc 客户端
vnc server 输入 ip:1 即可连接
