Running the In-Place Upgrade Script

Overview

This article goes over how to run the in-place upgrade script to update to version 3.003.03.

Instructions

SSH into the VM and run this command to elevate your privileges:

sudo su

Next, run a wget command to download the script:

wget https://thorntech-products.s3.amazonaws.com/sftpgateway/3.003.03/in-place-upgrade.sh

Give the script execute permissions:

chmod +x in-place-upgrade.sh

Finally, run the script:

./in-place-upgrade.sh

When you refresh your Web Admin UI you should now see an updated UI and version at the bottom.

Here are the contents of the script for reference:

#!/bin/bash

#
# Preparation
#

# Show debug output, and halt on errors
set -xe

# Must run script as root, or else show usage
if [[ $(whoami) != "root" ]]; then
  echo "Usage: sudo $0"
  exit 1
fi

function extractPropValueFromSourceFile {
    local prefix="${1}"
    local str=`grep "${prefix}" ${2} 2>/dev/null`
    echo "${str#$prefix}" | xargs
}

# If on version 2, exit script as the command sftpgw version is only on version 2.x
command -v sftpgw version >/dev/null && exit

# Set target version
TARGET_VERSION="3.3.3"
TARGET_VERBOSE_VERSION="3.003.03"

# Set date
TODAY=$(date +"%m%d%Y")

# Determine the cloud provider
AWS_DOMAIN=$(curl -s "http://169.254.169.254/latest/meta-data/services/domain")
AZURE_DOMAIN=$(curl --noproxy "*" -H 'Metadata: True' "http://169.254.169.254/metadata/instance/compute/azEnvironment?api-version=2019-06-01&format=text")
CLOUD_PROVIDER=gcp
[[ $AWS_DOMAIN   == "amazonaws.com"    ]] && CLOUD_PROVIDER=aws
[[ $AZURE_DOMAIN == "AzurePublicCloud" ]] && CLOUD_PROVIDER=azure

# Determine operating system and Nginx user
if getent passwd www-data > /dev/null 2>&1; then
  OS=ubuntu
  NGINX_USER=www-data
else
  OS=centos
  NGINX_USER=nginx
