How to Install Imunify360 on Supported OS

Imunify360 is a comprehensive security solution for Linux web servers, providing malware detection, firewall, patch management, and proactive defense. This guide walks you through installing Imunify360 on CentOS, AlmaLinux, Rocky Linux, Ubuntu, and Debian servers.

Prerequisites

• ✔ Root SSH access to the server or user with sudo privileges
• ✔ Ensure your server has internet access to download packages
• ✔ Backup important data before proceeding

Step-by-Step Installation Commands

1. Step 1: Login to your server as root via SSH:

   ssh root@your-server-ip

2. Step 2: Update your system packages:

   # For CentOS/AlmaLinux/Rocky Linux:
   yum update -y
   
   # For Ubuntu/Debian:
   apt-get update && apt-get upgrade -y
         

3. Step 3: Download the Imunify360 installation script:

   wget https://repo.imunify360.cloudlinux.com/defence360/i360deploy.sh

4. Step 4: Run the installation script:

   bash i360deploy.sh

5. Step 5: Restart the server (recommended after install):

   reboot

6. Step 6: Check if Imunify360 service is running:

   systemctl status imunify360

7. Step 7: If the license is not detected or shows a quota/license error, manually register it:

   /usr/bin/imunify360-agent register YOUR_LICENSE_KEY

   Replace YOUR_LICENSE_KEY with your actual key.
   Note: Use this command only if automatic activation fails or returns an error like:
   "Unable to register license: quota exceeded" or "License not found".
8. Step 8: Enable Imunify360 to start at boot (optional):

   systemctl enable imunify360
