Introduction
OpenIAM is a software platform that helps businesses manage user identities and control access to applications securely. It ensures that the right people have the right access at the right time.
Key Features:
✅ Maintains a unified record of user identities across systems.
✅ Automates user account creation and removal.
✅ Enforces security rules like Multi-Factor Authentication (MFA) and Role-Based Access Control (RBAC).
✅ Provides a self-service portal for password resets and access requests.
✅ Supports Single Sign-On (SSO) for easy and secure logins.
Deployment Options
You can install OpenIAM in two main ways:
- On-Premises: Install OpenIAM on your organization's own servers.
- Cloud-Based: Deploy OpenIAM in a cloud environment (AWS, Azure, Google Cloud, etc.).
One common method to install OpenIAM on Linux systems is via RPM (Red Hat Package Manager). The RPM installer includes almost everything except for the database and some system tools that must be set up separately.
Deployment Types
| Deployment Type | Description | Best For |
|---|---|---|
| Single VM Deployment | Everything runs on one machine. | ✅ Beginners & Testing |
| High Availability Deployment | Uses multiple servers for reliability. | Large-scale production |
| Multi-Tier Deployment | Separates components (UI, services, infrastructure). | Custom enterprise needs |
Using Single VM Deployment
This guide focuses on Single VM Deployment, where all OpenIAM components run on a single machine. This is the easiest deployment method and is best suited for beginners or non-production environments.
Step 1: Check System Requirements
Non-Production System Requirements
- Memory: 48GB RAM
- CPU: 8 cores
- Disk Space: 80GB
Why Do These Requirements Matter in the Cloud?
Even in cloud deployments, you must allocate enough virtual resources (RAM, CPU, disk space) to ensure OpenIAM functions properly.
Verify System Configuration
Run the following commands to check your system:
# Check CPU
lscpu
# Check memory (RAM)
free -m
# Check OS version
cat /etc/os-release
# Check disk space
df -H
Step 2: Download CentOS
To install OpenIAM, you need a compatible Linux distribution. You can download CentOS here:
Step 3: Connect to Your VM
3.1 Get Your VM’s IP Address
Run the following command to find your VM’s IP:
ip addr
3.2 Connect to Your VM via SSH
Use a terminal or PuTTY (for Windows) to SSH into your VM:
ssh [username]@[your VM's IP]
Example:
ssh root@172.16.101.128
Step 4: Install Required Packages
Before installing OpenIAM, install essential system packages.
4.1 Install Tar Utility
For CentOS 8+:
dnf install tar
Step 5: Choose Installation Method
- Install with Internet Access – Downloads necessary files during installation.
Step 6: Start the Installation
Now you’re ready to install OpenIAM. Follow the official installation steps based on your chosen deployment type.
