Centos 7 安装VNC

yum update -y

yum groupinstall "X Window System" -y

yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts -y

unlink /etc/systemd/system/default.target

ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target

yum install tigervnc-server -y

cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service

--------------------------------------------------------------------------------------------------------------------------------

vim /etc/systemd/system/vncserver@:1.service

接着我们用自己最喜欢的编辑器（这儿我们用的 nano ）打开 /etc/systemd/system/vncserver@:1.service ，找到下面这几行，用自己的用户名替换掉 。举例来说，我的用户名是 linoxide 所以我用 linoxide 来替换掉 ：

ExecStart=/sbin/runuser -l <USER> -c "/usr/bin/vncserver %i"

PIDFile=/home/<USER>/.vnc/%H%i.pid

替换成

ExecStart=/sbin/runuser -l linoxide -c "/usr/bin/vncserver %i"

PIDFile=/home/linoxide/.vnc/%H%i.pid

如果是 root 用户则

ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"

PIDFile=/root/.vnc/%H%i.pid

--------------------------------------------------------------------------------------------------------------------------------

systemctl daemon-reload

vncpasswd

systemctl enable vncserver@:1.service

systemctl start vncserver@:1.service
