Upgrade Guacamole server

This section describes how to upgrade the Guacamole server as part of the upgrade to Abiquo 6.1.2 or higher.
This upgrade is for remote access to public cloud and it is optional for customers that only use vCenter with WebMKS

To use the latest version of Guacamole, install and run it in a Docker container on each Remote Services server.

Log in to each Remote Services server, and create and run the following script.

#!/bin/bash

# Check if the file exists
if [ -f "/etc/guacamole/guacd.conf" ]; then
    # Check if the line already exists in the file
    if grep -q "bind_port = 4820" "/etc/guacamole/guacd.conf"; then
        echo "The line 'bind_port = 4820' already exists in the file."
    else
        # Append the line to the file
        echo "bind_port = 4820" | sudo tee -a "/etc/guacamole/guacd.conf" >/dev/null
        echo "The line 'bind_port = 4820' has been added to the file."
    fi
else
    echo "File '/etc/guacamole/guacd.conf' does not exist."
fi

# Start docker
if [ -x /usr/bin/systemctl ]; then
  echo "Enabling and starting Docker..."
  /usr/bin/systemctl enable docker
  /usr/bin/systemctl start docker
  /usr/bin/systemctl stop guacd
  echo "Docker started successfully."
fi
