CentOS installation Novnc, web-delivered VNC remote connection

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.

Create a secure connection (go all the way down ...) ）

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

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 Websockify will automatically load the certificate when NoVNC is started.
Run Novnc

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