Novnc connects to CentOS to deliver VNC remote connections on the Web

What is NOVNC?

• NoVNC is a HTML5 VNC client with HTML 5 WebSockets, Canvas and JavaScript implementations, and NoVNC is commonly used in cloud computing, virtual machine control panels such as OpenStack Dashboard and Op Ennebula Sunstone all used NoVNC.

• NoVNC is implemented with WebSockets, but most VNC servers currently do not support WebSockets, so NoVNC is not directly connected to the VNC server and requires an agent to convert between WebSockets and TCP sockets. This agent is in the NoVNC directory, called Websockify.

Experimental environment

• Operating system: CentOS 6.6

• ip:192.168.204.128

First, modify the network configuration

1) Close the protective wall

12	setenforce 0service iptables stop

2) View native IP address

Second, install Git

1	yum installgit -y

Three, installation configuration Tigervnc

12	yum installtigervnc-servervncserver :1

To install the Tigervnc-server process:

Enter Vncserver:1 to start the service and enter the password (note that the password is not less than 6 bits long).

Iv. installation of NoVNC

1) Download NoVNC

1	git clone git://github.com/kanaka/noVNC

2) Create a secure connection

^ Note: The default session of VNC is not secure and requires creating a secure VNC connection. The created certificate ' SELF.PEM ' needs to be placed in the ' novnc/utils ' directory, and when NoVNC is started,websockify will automatically load the certificate.

12	cd./noVNC/utils/openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem

Go all the way down ...

3) Running NoVNC

12	# 在noVNC目录下，执行./utils/launch.sh --vnc localhost:5901

V. Test connection

In browser access (note Replace with your own IP address) http://192.168.204.128:6080/vnc.html

Enter the password, the connection is successful!
