This is a standard offline repo setup for Red Hat Enterprise Linux
🧱 PART 1: Setup Repo Server (VM1)
🔧 Step 1: Install required tools
sudo dnf install -y dnf-plugins-core createrepo
📁 Step 2: Create repo directory
sudo mkdir -p /repo
cd /repo
📦 Step 3: Download packages + dependencies
👉 Example (MongoDB):
sudo dnf download --resolve mongodb-enterprise-server mongodb-mongosh
👉 You can add more packages anytime:
sudo dnf download --resolve <package-name>
🔍 Step 4: Verify RPMs
ls -lh /repo
👉 Must show .rpm files ✅
🏗️ Step 5: Create repository metadata
sudo createrepo /repo
🌐 Step 6: Start repo server
Quick method (for testing)
cd /repo
python3 -m http.server 8080
👉 Repo URL:
http://<VM1-IP>:8080
🔥 (Production recommended) Use Apache
sudo dnf install -y httpd
sudo systemctl enable httpd
sudo systemctl start httpd
Copy repo:
sudo cp -r /repo /var/www/html/
👉 URL becomes:
http://<VM1-IP>/repo
🧱 PART 2: Configure Client VMs (VM2 & VM3)
🔧 Step 7: Create repo config
sudo vi /etc/yum.repos.d/local.repo
Paste:
[local-repo]
name=Local Repo
baseurl=http://<VM1-IP>:8080
enabled=1
gpgcheck=0
👉 If using Apache:
baseurl=http://<VM1-IP>/repo
🔄 Step 8: Refresh repo
sudo dnf clean all
sudo dnf makecache
🔍 Step 9: Verify packages
dnf list available | grep mongo
👉 Packages should appear ✅
🧱 PART 3: Install Packages from Repo
📥 Step 10: Install
sudo dnf install -y mongodb-enterprise-server mongodb-mongosh
🔄 PART 4: Adding New Packages Later
On VM1:
cd /repo
sudo dnf download --resolve <new-package>
sudo createrepo --update /repo
On VM2:
sudo dnf clean all
sudo dnf makecache
🧠 Best Practices
✅ Always use:
dnf download --resolve
✔ ensures dependencies included
✅ Keep repo updated:
createrepo --update /repo
✅ Use Apache for stability
- survives reboot
- production ready
🎯 Final Architecture
VM1 (Repo Server)
↓ HTTP
VM2 -------- VM3
(install packages from VM1)
🚀 You now have
- Offline package management ✅
- Centralized repo server ✅
- No need for subscription on other VMs ✅
👍 If you want next level
I can help you:
- 🔄 Sync full RHEL repo locally (mirror)
- ⚙️ Automate with Ansible
