You must upgrade your Ansible Tower 2.4.4 (or later) system to Ansible Tower 3.0 before you can upgrade to Ansible Tower 3.1.0.
This section covers changes that you should keep in mind as you attempt to upgrade your Ansible Tower Instance
./configure/as part of the initial setup.
tower_setup_conf.ymlis no long used. Instead, you should now edit the inventory file in the
Download and then extract the Ansible Tower installation/upgrade tool: http://releases.ansible.com/ansible-tower/setup/
To install or upgrade, start by editing the inventory file in the
ansible-tower-setup-<tower_version> directory, replacing
<tower_version> with the version number, such as
As you edit your inventory file, there are a few things you must keep in mind:
./inventory, next to the
localhostwith the hostname or IP address of all instances. All nodes/instances must be able to reach any others using this hostname or address.
Changes made to the installation process now require that you fill out the all of the password fields in the inventory file. If you need to know where to find the values for these they should be:
admin_password=''<— Tower local admin password
pg_password=''<—- Found in /etc/tower/conf.d/postgres.py
rabbitmq_password=''<—- create a new password here
Example Inventory file
Example Single Node Inventory File
[tower] localhost ansible_connection=local [database] [all:vars] admin_password='password' pg_host='' pg_port='' pg_database='awx' pg_username='awx' pg_password='password' rabbitmq_port=5672 rabbitmq_vhost=tower rabbitmq_username=tower rabbitmq_password='password' rabbitmq_cookie=rabbitmqcookie # Needs to be true for fqdns and ip addresses rabbitmq_use_long_name=false
Example Multi Node Cluster Inventory File
[tower] clusternode1.example.com clusternode2.example.com clusternode3.example.com [database] dbnode.example.com [all:vars] ansible_become=true admin_password='password' pg_host='dbnode.example.com' pg_port='5432' pg_database='tower' pg_username='tower' pg_password='password' rabbitmq_port=5672 rabbitmq_vhost=tower rabbitmq_username=tower rabbitmq_password=tower rabbitmq_cookie=rabbitmqcookie # Needs to be true for fqdns and ip addresses rabbitmq_use_long_name=true
Example Inventory file for an external existing database
[tower] node.example.com ansible_connection=local [database] [all:vars] admin_password='password' pg_password='password' rabbitmq_password='password' pg_host=‘database.example.com’ pg_port=’5432’ pg_database='awx' pg_username='awx' pg_password='password'
Example Inventory file for external database which needs installation
[tower] node.example.com ansible_connection=local [database] database.example.com [all:vars] admin_password='password' pg_password='password' rabbitmq_password='password' pg_host=‘database.example.com’ pg_port=’5432’ pg_database='awx' pg_username='awx' pg_password='password'
Once any necessary changes have been made, you are ready to run
Root access to the remote machines is required. With Ansible, this can be achieved in different ways:
- ansible_ssh_user=root ansible_ssh_password=”your_password_here” inventory host or group variables
- ansible_ssh_user=root ansible_ssh_private_key_file=”path_to_your_keyfile.pem” inventory host or group variables
- ANSIBLE_BECOME_METHOD=’sudo’ ANSIBLE_BECOME=True ./setup.sh
- ANSIBLE_SUDO=True ./setup.sh
Ansible Tower 3.0 simplifies installation and removes the need to run
./configure/ as part of the installation setup. Users of older versions should follow the instructions available in the v.2.4.5 (or earlier) releases of the Tower Documentation available at:
The Tower setup playbook script uses the
inventory file and is invoked as
./setup.sh from the path where you unpacked the Tower installer tarball.
[email protected]:~$ ./setup.sh
The setup script takes the following arguments:
-h– Show this help message and exit
-i INVENTORY_FILE– Path to Ansible inventory file (default:
-e EXTRA_VARS– Set additional Ansible variables as key=value or YAML/JSON (i.e.
-e bundle_install=falseforces an online installation)
-b– Perform a database backup in lieu of installing
-r– Perform a database restore in lieu of installing (a default restore path is used unless EXTRA_VARS are provided with a non-default path, as shown in the code example below)
./setup.sh -e 'restore_backup_file=/path/to/nondefault/location' -r
Please note that a issue was discovered in Tower 3.0.0 and 3.0.1 that prevented proper system backups and retorations.
If you need to back up or restore your Tower v3.0.0 or v3.0.1 installation, use the v3.0.2 installer to do so.
