V? N? C? Server? ?? Ann? Installation? And Configuration

1. VNC server configuration on RedHat

This article takes the VNC Server not installed in the current Linux system as the basis. If you have installed it, Skip section 1st!

Prerequisites:

1. Install tigervnc Server

# yum search tigervnc-server

# yum install tigervnc-server.x86_64

# vncpasswd

First, run vncpasswd as the user identity to be remotely logged on to set the login password, at least six digits. This password is used during client connection.

 

2.Configure graphical interface

Modify the configuration file, activate the graphical interface, and run the following command:

# vi /root/.vnc/xstartup

Comment out this line

# TWM & // comment the row

Add a row at the end

Gnome-session & // Add this row

Save and exit

3. Start the VNC service

Execute Command

# /etc/init.d/vncserver start

Or

# service vncserver start

Prompt after startup:

Starting VNC server: no displays configured [FAILED]

Solution:
Run the following command to modify the last two lines:

# vim /etc/sysconfig/vncservers

Modify the last two rows, for example:

VNCSERVERS="1:root"VNCSERVERARGS[1]="-geometry 1024x768"

Note: The first act service is configured. Currently, only one VNC service is configured and started with the user root. If you need to log on with another user, you can modify the value of vncservers, for example, "1: root 2: Tiger "(Tiger is another user in the system ). The second line can be commented out, which is to configure the window resolution. You need to remove the-localhost

The VNC Server is automatically started with the system.

Execute Command

# sudo chkconfig --level 345 vncserver on

 

4. Stop the VNC service

Execute Command

# /etc/init.d/vncserver stop

Or

# service vncserver stop

 

Ii. Access Linux Through VNC Viewer in Windows

First install RealVNC, download it from the Internet, start-run VNC Viewer, enter the IP address, and the following: 1 indicates to log on with the root user, 1: Root configured on RH, if you want to log on with another user, adjust the number after the colon. The password is previously configured.

 

Solution to connection failure

Run the command to check what port the VNC listens to. open the port in the firewall.

# netstat -ntupl|grep vnc

The returned list is as follows:

1. tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 4411/Xvnc 2. tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 4411/Xvnc 3. tcp 0 0 :::6001 :::* LISTEN 4411/Xvnc

Modify the firewall configuration file and open port 5901.

# vi /etc/sysconfig/iptables

You can copy a row of port 22 and paste it to modify it to restart the Firewall Service.

# service iptables restart
