VNC is a wide range of server management software, you can achieve graphical management, the following is a brief introduction to how to install VNC under centos6.7.
Installing Vncserver
Yum Install Tigervnc tigervnc-server-y
Configure Vncserver
VI /etc/sysconfig/vncserver
Remove the following two lines of # in the file
# vncservers="2:myusername"# vncserverargs[2]="- Geometry 800x600-nolisten tcp-localhost"
and modify the user name and monitor resolution according to your needs:
vncservers="2:root"vncserverargs[2]="- Geometry 1024x768 -nolisten tcp-localhost"
To set the VNC access password:
vncpasswd
Note: This is a password for the root remote user above, so it is available under the root account, and so on, for other accounts with the password, it is necessary to use the command under another account .
Set Iptables:
Iptables firewall will block VNC Remote Desktop by default, so it needs to be allowed in iptables. When you start the VNC service, you can use the NETSTAT–TUNLP command to view the port used by the VNC service, you can find 5801,5901,6001 and so on. Use the following command to turn on these ports:
Vim/etc/sysconfig/iptables
Add to:
5801 -J Accept5901 -J Accept6001 -j Accept
To restart the firewall:
/etc/init.d/iptables restart
Or shut down the firewall directly:
/etc/init.d/iptables stop
Problems you may encounter:
A, black screen
Installed in Linux in the configuration of the VNC server, the discovery of multi-user login will appear black screen situation, the specific phenomenon is:
The client can enter the system via IP to the session number, but landing in is dark, except for a forked mouse, pitch.
Cause: The user's VNC startup file permissions are not set correctly.
Workaround: Modify the properties of the black screen user's Xstartup (typically:/user directory/.vnc/xstartup) file to 755 (rwxr-xr-x).
After that, kill all the VNC clients that have started:
Vncserver-kill:1
Vncserver-kill:2 (Note:-kill with: 1 or: 2 with a space in the middle)
Finally restart the Vncserver service! #/etc/init.d/vncserver Restart
Note: Vncserver can only be turned off by the user who initiated it, and instant root cannot turn off the vncserver that other users have opened.
Kill the process unless you use kill to order the violence.
