A detailed explanation of VNC Remote Desktop installation and configuration method in Linux system

Specific methods

1. Check whether the Linux system installs VNC command Rpm-q vnc-server
Use yum install VNC vnc-server if it is not installed
2. Start VNC Service

The code is as follows	Copy Code
Vncserver You'll require a password to access your desktops. Password: Verify:

Enter the password two times, which is the password you need to log on remotely.
3. Modify configuration file, root account

The code is as follows	Copy Code
Vi/etc/sysconfig/vncservers

New and below configuration

The code is as follows	Copy Code
vncservers= "10000:root" #10000: Root (Desktop number: User) vncserverargs[2]= "-geometry 1024x768-nolisten tcp-localhost"

4. Configure the firewall to allow the 10000+5900=15900 port to access the desktop through the firewall

The code is as follows	Copy Code
Vi/etc/sysconfig/iptables -A input-m state–state new-m tcp-p tcp–dport 15900-j ACCEPT

5. Restart VNC services and firewalls.

The code is as follows	Copy Code
/etc/init.d/vncserver restart /etc/init.d/iptables restart

6. Set VNC self-boot

The code is as follows	Copy Code
Chkconfig Vncserver on

Change password you can use the VNCPASSWD command

The above is my operation process, later from sentient beings to find a picture and text of the tutorial, we do not refer to the

Use SSH software to connect to the system, start VNC service with command vncserver

The first time you use vncserver prompts for a password, and then retype it again (enter geisnic.com here

As a password, you must remember this password), enter the following figure prompts:

Remember dispay# here, this is feng:1,display# is 1.

Open the file in the current user's home directory. Vnc/xstartup, because this is the root user, so the file is in the/root directory, after opening the file, comment out all rows, add a line Gnome-session &, save exit.

Using the command Vncserver-kill:d ispaly# The dispaly# view is shown in the previous steps, here is 1, enter command return

Re-use the command vncserver restart the service

Remember that the dispaly# here is 1.

Vncserver default port is 5900, this port is open in the firewall

Vi/etc/sysconfig/iptables

Locate the following statement:

-A rh-firewall-1-input-j Reject--reject-with icmp-host-prohibited

Before this trip, add the following:

-A rh-firewall-1-input-m state--state new-m tcp-p TCP--dport 5900:5903-j ACCEPT

Then restart the Iptables service: Services iptables restart

Can.

Open the Software vnc Viewer (VNC client) on the local system and enter the machine's IP address plus dispaly#

Here is 118.126.16.219:1

Point OK, the following input box appears, enter the password you just set geisnic.com

Click OK to log on to the system

Set Vncserver to boot automatically: Chkconfig vncserver on
