### 设置默认启动图形界面
# unlink /etc/systemd/system/default.target
# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target
# reboot
|
2.安装 tigervnc server and X11 fonts
1
|
yum install tigervnc-server xorg-x11-fonts-Type1
|
拷贝VNC server configuration 文件到 /etc/systemd/system 下进行配置。VNC默认端口为5900，你可以直接通过5900端口登录VNC，也可以自己设置一个子端口。比如，我将子端口设成5，那么登录的端口就是5905,你可以通过ipaddress:sub-port(192.168.1.1:5或者192.168.1.1:5905)来登录。

New 'localhost.localdomain:1 (raj)' desktop is server.itzgeek.com:1
Creating default startup script /home/archie/.vnc/xstartup
Starting applications specified in /home/archie/.vnc/xstartup
Log file is /home/archie/.vnc/server.itzgeek.com:1.log
