## Make sure the machine meets the ansible tower requirements

RHEL 64bit
RAM > 4GB
HDD > 20GB


## download the ansible installer bundle

cd /var/tmp
wget --no-check-certificate https://releases.ansible.com/ansible-tower/setup/ansible-tower-setup-latest.tar.gz


## extract
## depending on the version number, it will create a sub directory with the version number e.g.
## ansible-tower-setup-3.8.4-1

tar cvfz ansible-tower-setup-latest.tar.gz


## edit the inventory file to insert passwords
## eg. if the extracted installer is in ansible-tower-setup-3.8.4-1

cd ansible-tower-setup-3.8.4-1
vi inventory


## modify accordingly

[tower]
localhost ansible_connection=local

[automationhub]

[database]

[all:vars]
admin_password='Your_Admin_Password_Here'

pg_host=''
pg_port=''

pg_database='awx'
pg_username='awx'
pg_password='Your_DB_Password_Here'
pg_sslmode='prefer'  # set to 'verify-full' for client-side enforced SSL


## if you want to tweak the installation requirements e.g. minimum RAM size, you can edit the variables in

[INSTALLDIR]/roles/preflight/defaults/main.yml



## run the installer and wait till completed.

./setup.sh
