Exercise 2.0 - Installing Ansible Tower

Return to Workshop

Exercise Description

In this exercise, we are going to get Ansible Tower installed on your control node.

Step 1: Change directories

Change directories to /tmp

cd /tmp

Step 2: Download Red Hat Ansible Tower

Download the latest Ansible Tower package

curl -O https://releases.ansible.com/ansible-tower/setup/ansible-tower-setup-latest.tar.gz

Step 3: Untar and unzip the package file

tar xvfz /tmp/ansible-tower-setup-latest.tar.gz

Step 4: Change directories

Change directories into the Ansible Tower setup package

cd /tmp/ansible-tower-setup-*/

Step 5: Open inventory file

Using an editor of your choice, open the inventory file

vim inventory

Step 6: Identify variables

Fill a few variables out in an inventory file: admin_password, pg_password, rabbitmq_password

localhost ansible_connection=local




pg_sslmode='prefer'  # set to 'verify-full' for client-side enforced SSL

# Isolated Tower nodes automatically generate an RSA key for authentication;
# To disable this behavior, set this value to false
# isolated_key_generation=true

# SSL-related variables

# If set, this will install a custom CA certificate to the system trust store.
# custom_ca_cert=/path/to/ca.crt

# Certificate and key to install in nginx for the web UI and API
# web_server_ssl_cert=/path/to/tower.cert
# web_server_ssl_key=/path/to/tower.key

# Server-side SSL settings for PostgreSQL (when we are installing it).
# postgres_use_ssl=False
# postgres_ssl_cert=/path/to/pgsql.crt
# postgres_ssl_key=/path/to/pgsql.key

Step 7: Run setup

Run the Ansible Tower setup script

sudo ./setup.sh
Step 7 will take approx. 10-15 minutes to complete. This may be a good time to take a break.

Step 8: Confirm results

At this point, your Ansible Tower installation should be complete. You can access your Tower workshop (not forgetting that workshopname is the name of your workshop, and # is your student number) at:
