centos7跟6比设置方法不一样
yum groupinstall "X Window System" -y
yum grouplist
yum groupinstall "GNOME Desktop" -y
yum install tigervnc* -y
cp /lib/systemd/system/vncserver@.service /lib/systemd/system/vncserver@:3.service
vi /lib/systemd/system/vncserver@:3.service
修改[Service]段内中的<USER>为需要开启的账户名称，如root，保存退出。
1 [Service] 2 Type=simple 3 # Clean any existing files in /tmp/.X11-unix environment 4 ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' 5 ExecStart=/usr/sbin/runuser -l root -c "/usr/bin/vncserver %i" 6 PIDFile=/root/.vnc/%H%i.pid 7 ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :' 8 9 [Install] 10 WantedBy=multi-user.target
保存后设置VNC用户密码
vncpasswd root
root123
systemctl daemon-reload
systemctl enable vncserver@:3.service
systemctl start vncserver@:3.service
如果启动不起来，做如下操作
rm -rf /tmp/.X11-unix/*
[root@localhost ~]# vncserver -list
TigerVNC server sessions:
X DISPLAY # PROCESS ID

vnc-viewer连接服务器IP:3或者服务器IP::5903. 注意写端口的时候是2个冒号
