```bash
# Start from the home directory of user account "dataiku"
# which will be used to run the Dataiku DSS
# We will install DSS using data directory: /home/dataiku/dss_data
$ pwd
/home/dataiku
$ ls -l
-rw-rw-r-- 1 dataiku dataiku 159284660 Feb  4 15:20 dataiku-dss-VERSION.tar.gz
-r-------- 1 dataiku dataiku       786 Jan 31 07:42 license.json

# Unpack the distribution kit
$ tar xzf dataiku-dss-VERSION.tar.gz

# If the User Isolation Framework is to be configured on this instance,
# make sure all user accounts have read-execute permission to the installation directory
$ chmod a+x .
$ umask 22

# Run installer, with data directory $HOME/dss_data and base port 10000
# This fails because of missing system dependencies
$ dataiku-dss-VERSION/installer.sh -d /home/dataiku/dss_data -l /home/dataiku/license.json -p 10000

# Install dependencies with elevated privileges, using the command shown by the previous step
$ sudo -i "/home/dataiku/dataiku-dss-VERSION/scripts/install/install-deps.sh"

# Rerun installer script, which will succeed this time
$ dataiku-dss-VERSION/installer.sh -d /home/dataiku/dss_data -l /home/dataiku/license.json -p 10000

# Manually start DSS, using the command shown by the installer step
$ /home/dataiku/dss_data/bin/dss start

# Connect to Dataiku DSS by opening the following URL in a web browser:
#    http://HOSTNAME:10000
# Initial credentials : username = "admin" / password = "admin"

# [Optional] To finalize the installation, restart as a system-managed service:
#
# Stop the manually-started instance
$ /home/dataiku/dss_data/bin/dss stop
#
# Create a system service, using the command shown by the previous step
$ sudo "/home/dataiku/dataiku-dss-VERSION/scripts/install/install-boot.sh" "/home/dataiku/dss_data" dataiku
#
# Start the system service
