VNC（Virtual Network Console）是在基于 UNIX 和 Linux 操作系統的免費的開源軟件。 ## 服務器端配置查詢vnc-sever ``` yum provides vnc-server yum info tigervnc-server ``` 安裝vnc-sever ``` yum install tigervnc-server -y ``` 創建用戶 ``` useradd user01 passwd user01 ``` 切換用戶，啟用vnc ``` su - user01 vncserver :1 You will require a password to access your desktops.
