Ready to
turn off the firewall
systemctl stop firewalld
setenforce 0
1, yum install VNC server, easily solve the problem of dependence:
yum -y install tigervnc-server
And did not install a desktop option if the system is installed, then you need to use yum install what desktop, VNC is a remote graphical because:
yum groupinstall "X Window System" "Desktop"
2. Edit vnc configuration file
editing / etc / sysconfig / vncservers,
add the following:
centos6
vim /etc/sysconfig/vncservers
VNCSERVERS="1:root"VNCSERVERARGS[1]="-geometry 800x600 -alwaysshared -depth 24"
centos7
vim /lib/systemd/system/vncserver@:1.service
[Unit]
Description=Remote desktop service (VNC)
After=syslog.target network.target
[Service]
Type=forking #[forking:root用户 simple:普通用户]
#Clean any existing files in /tmp/.X11-unix environment
ExecStartPre=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"
PIDFile=/root/.vnc/%H%i.pid
ExecStop=/bin/sh -c '/usr/bin/vncserver -kill %i > /dev/null 2>&1 || :'
Note: The resolution can be adjusted according to the actual situation, the resolution is improper connection may lead to vnc display a black screen phenomenon.
3. Set the VNC password
can be used to modify the command vncpasswd
vncpasswd
4. View vnc session information
to restart the vncserver service:
centos6
/etc/init.d/vncserver restart
centos7
systemctl daemon-reload
systemctl restart vncserver@:1.service
chmod 777 /root/.vnc/xstartup #解决黑屏问题
View a vnc session information:
vncserver -list
5. Client vnc connection test
client is vncviewer, I have here is a Windows system
Enter 10.0.0.41:1, this is my vnc server IP
After determining, prompted for a password, the password here is the vnc password,
OK, you can connect to the server's desktop environment through vnc.
When the above situation may be automatically put out screen
Note: Here "10.0.0.41" is the server's IP address, while ": 1" corresponds VNCSERVERS configuration, this is the root user.
VNC personally think the biggest advantage is: the network suddenly disconnected, it will not affect the operation being done before.
