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
