Start VNC Server, refer to here (section [1]).
This example is based on that "cent" user runs VNC server with 5901 port.
[3] Start Websockify with the user who runs VNC server and proxying localhost:5901 on port 6080.
[cent@dlp ~]$ websockify -D --web=/usr/share/novnc/ --cert=/etc/pki/tls/certs/novnc.pem 6080 localhost:5901
WebSocket server settings:
- Listen on :6080
- Flash security policy server
- Web server. Web root: /usr/share/novnc
- SSL/TLS support
- Backgrounding (daemon)
[4] Access to the "http://(server's hostname or IP address):6080/" from a client with web browser, then noVNC form is displayed like follows, Login with VNC password.

[5] Just connected. It's possible to operate CentOS on Web browser.
