| - | ====== š§ Centralized | + | ====== š§ Zentrale |
| - | To streamline the administration of the entire infrastructure, a centralized management node was deployed. This allows for simultaneous updates, command execution, and service monitoring across all virtual machines from a single interface. | + | Wir haben ein System gebaut, um alle Server an einem Ort zu kontrollieren. Das ist einfacher fĆ¼r die Administration und sehr sicher. |
| - | ===== 1. Master-Slave Architecture | + | ===== 1. Architektur (Master |
| - | The management system follows a Master-Slave topology where a dedicated VM acts as the orchestrator for other infrastructure components. | + | Es gibt einen "Master" Server (das Gehirn). Dieser Master sieht und kontrolliert alle anderen "Slave" Server. |
| - | ^ Role ^ Hostname | + | ^ Rolle ^ Name ^ IP Adresse |

| - | ===== 3. Network & DNS Integration | + | ===== 3. DNS Konfiguration |
| - | To enhance usability, a local domain was assigned to the management interface. | + | Wir benutzen einen Namen statt einer IP Adresse. Das ist einfacher zu merken. |
| - | * **DNS Record:** A new A-Record was added to the FreeBSD BIND9 server.Ā | + | * **DNS Name:** webmin.berkay.localĀ |
| - | * Record: '' | + | * **Ziel:** Dieser Name zeigt direkt auf unseren Master Server |
| - | * **Reverse Proxy (Optional):** Initial tests were performed with Nginx Proxy Manager | + | |
| - | ===== 4. Security Hardening | + | ===== 4. Sicherheit (Firewall) |
| - | Strict security measures were applied to the management port (10000). | + | Wir haben den Port 10000 in der Firewall erlaubt. Nur so kƶnnen die Server miteinander sprechen. |
| - | **Firewall Configuration (UFW):** | ||
| < | < | ||
| + | # Port 10000 erlauben (UFW) | ||
| sudo ufw allow 10000/tcp | sudo ufw allow 10000/tcp | ||
| sudo ufw reload | sudo ufw reload | ||
| </ | </ | ||
| - | **Access Control: | + | Wir haben auch die Datei ''/ |
| - | Configuration was modified in ''/ | + | |
| - | < | + | |
| - | referers=webmin.berkay.localĀ | + | |
| - | trust_real_ip=1Ā | + | |
| - | </ | + | |
| - | ===== 5. Centralized Operations | + | ===== 5. Was haben wir gemacht? |
| - | With this setup, the following tasks are now automated across the cluster:Ā | + | Mit diesem System kƶnnen wir jetzt:Ā |
| - | * **Cluster Shell Commands:** Run '' | + | * **Alle Server gleichzeitig updaten.**Ā |
| - | * **Unified Monitoring:** View CPU, RAM, and Disk usage for all nodes in one dashboard.Ā | + | * **Einen Befehl an alle Server schicken.**Ā |
| - | * **User Management:** Create or modify administrative accounts globally. | + | * **CPU und RAM von allen Computern auf einer Seite sehen.** |

| - | **Summary:** The deployment of the Webmin Master Node successfully unified the management of Debian and FreeBSD | + | **Zusammenfassung:** Die zentrale Verwaltung spart viel Zeit. Wir kƶnnen jetzt FreeBSD |
