Article Summary

The following is a step-by-step guide for installing IAG on RHEL 8.

⚠ If you are installing Automation Gateway on a different platform you will need to install/compile Python 3.9. After installing Python 3.9 follow the steps starting with Setup Directory and Virtual Environment.

⚠ If you encounter any problems during the install or have questions, please contact the Product Support Team.

Root Access

This document assumes that you will have root access on the server you will be installing IAG on.

sudo su

Install System Packages

Use the following to install system packages.

dnf -y install python39 python39-devel make gcc-c++

Set Up Directory and Virtual Environment

Use the following to set up the directory and virtual environment.

mkdir /opt/automation-gateway
cd /opt/automation-gateway
python3.9 -m venv .venv

The following command will activate the virtual environment for your current session.

source /opt/automation-gateway/.venv/bin/activate

Make sure you are in the virtual environment for all following commands.

Include the Virtual Environment in Default Shell

This command is optional but recommended and will allow every shell you open to have the virtual environment.

echo source /opt/automation-gateway/.venv/bin/activate > /etc/profile.d/venv.sh

Install Automation Gateway

Work with your Itential Account Manager to obtain the whl file. Place this file in /tmp on the IAG server.

You will need to change <version> to be the version of IAG you are installing. For example: pip install /tmp/automation_gateway-3.198.19+2022.1.8-py3-none-any.whl

pip install /tmp/automation_gateway-<version>-py3-none-any.whl

Install Ansible

Run the following to install Ansible.

pip install ansible==2.10.7

Install Terraform (Optional)

If the following does not work on your platform you can download Terraform directly using this link: Install Terraform Directly.

yum install -y yum-utils
yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
yum -y install terraform

Service Configuration

The following configurations can be changed to reflect your environment. By default Itential runs Automation Gateway using gunicorn. You may want to add an additional front-end HTTP server (e.g., NGINX, HAProxy) in front of this service configuration. Settings that use NGINX or HAProxy are outside the scope of this documentation.

Create User

Create a user that will run automation-gateway using gunicorn.

useradd itential

Set Up Folders

Set up your folders for the database, logs, and other files.

mkdir /var/lib/automation-gateway
mkdir /etc/automation-gateway
chown itential /var/lib/automation-gateway

Automation Gateway Configuration

Copy the configuration included in the release and modify it for your needs.

cp \
  /opt/automation-gateway/.venv/lib64/python3.9/site-packages/automation_gateway/properties.yml \

Modify the following file with a preferred text editor to make any changes that are relevant to your environment and differ from the default.


Systemd Configuration

To configure systemd for automation-gateway, create the following file with a preferred text editor.


Use the following default configuration for systemd:

Description=Itential Automation Gateway

ExecStart=/opt/automation-gateway/.venv/bin/automation-gateway --properties-file=/etc/automation-gateway/properties.yml


Enable automation-gateway on boot and start the service.

systemctl enable automation-gateway
systemctl daemon-reload
systemctl start automation-gateway

Check the Status of the Service

Verify the service has started correctly.

systemctl status automation-gateway

Open Automation Gateway in a Web Browser

Server is the name of the host you installed IAG on.

Default username: admin@itential
Default password: admin

Install Additional Content

You can now install additional custom content, playbooks, and scripts to use with IAG.

# Create the custom content directories to match your configuration (below is default)
mkdir -p /usr/share/automation-gateway/ansible/inventory \
         /usr/share/automation-gateway/ansible/modules \
         /usr/share/automation-gateway/ansible/roles \
         /usr/share/automation-gateway/ansible/collections \
         /usr/share/automation-gateway/ansible/playbooks \
         /usr/share/automation-gateway/nornir/modules \
         /usr/share/automation-gateway/scripts \

chown -R itential /usr/share/automation-gateway/

Folders and Files

By default IAG uses the following folders and files.
