noVNC settings

Here is the instruction how to configure noVNC:

  1. Set up noVNC in SolusVM > Configuration > Settings > Other

    • noVNC Admin - Disable/Enable noVNC in the admin area
    • noVNC Client - Disable/Enable noVNC in the client area
    • noVNC Socket Port - The port number the websockify daemon runs on. Default is 7706
    • noVNC Socket Location - Set up Master as socket Host.
  2. Connect to master server via SSH and isntall necessary packages:

    yum install python numpy python-ssl
  3. Setup SSL certificate for noVNC. It should be placed in the file /usr/local/solusvm/includes/nvnc/cert.pem/ Execute the following commands:

    cat /usr/local/svmstack/nginx/ssl/ssl.crt /usr/local/svmstack/nginx/ssl/ssl.key > /usr/local/solusvm/includes/nvnc/cert.pem
    systemctl restart svmstack-nginx.service 
  4. Several advanced settings exist in the masters /usr/local/solusvm/data/config.ini for noVNC:

    [NOVNC]
    ;;Set this to true if you want noVNC to access the websocket with the remote servers hostname. All the hostnames must resolve correctly. Default (false) is to use the ip address of the remote server
    use_remote_hostname = true
    			
    ;;Set this to true if you want the socket on the host to forward packets across the public network
    socket_dest_public = false

noVNC troubleshooting

To debug socket connections you can manually start websockify on the host (Make sure you do this on the correct server and you specify the correct port):

sh /scripts/websocket-stop
php /usr/local/solusvm/includes/wsocket.php --port=7706 --debug=1

After that open noVNC console and check the logs in the terminal.

Never start websockify without the --debug=1 flag manually as root. SolusVM will automatically start it if it's not running.
