The Build Order
1. Base OS: Install your chosen Linux distro. Configure SSH keys, firewall, and basic security.
2. Networking Foundation: Set up DHCP and DNS first. Without these, nothing else works smoothly.
3. Core Services: Add web server, then database. Test each independently.
4. Identity Management: Deploy LDAP before adding user-dependent services.
5. Virtualization Layer: Add KVM/Podman for isolation and scalability.
6. Redundancy: Clone to backup hardware. Configure automatic failover.
The Mantra
One Primary, One Backup. For every critical service, have a second box (even a Raspberry Pi) ready to take over. Automate it with keepalived or good ol' cron scripts.
Lab Bench Note: Your datacenter is a living project. It will hum, it will break, you will fix it. You will know every wire and config file. That's the point. This machine is a territory. Defend it.
Start with what you need today. A file server? A local wiki? A Pi-hole equivalent? Build that one service perfectly. Document everything. Then add the next. This incremental approach prevents overwhelm and creates truly resilient infrastructure.
sudo dnf install nginx mariadb-server bind9
The command above is how it begins. Three packages. One service. Then you grow. Your datacenter becomes a living organism you understand completely—because you built it, piece by piece.
