Kategorie:Server

This article details the standard server configuration for systems classified under the "Kategorie:Server" designation on this wiki. It is intended as a guide for new administrators and those seeking to understand the baseline infrastructure. This configuration aims for stability, performance, and scalability. Please consult the System Administration Policy before making any changes. All servers within this category must adhere to these guidelines.

Overview

Servers categorized under "Kategorie:Server" generally support mission-critical applications and services. They are typically deployed in a clustered environment to ensure high availability. This documentation covers hardware specifications, operating system details, software stacks, and important configuration notes. Understanding the Networking Infrastructure is also crucial for successful server management. Remember to always follow the Security Best Practices when working with these systems.

Hardware Specifications

The following table outlines the minimum and recommended hardware specifications for servers within this category.

Component Minimum Specification Recommended Specification
CPU Intel Xeon E5-2680 v4 (or AMD equivalent) Intel Xeon Gold 6248R (or AMD equivalent)
RAM 64 GB DDR4 ECC 128 GB DDR4 ECC
Storage (OS) 500 GB SSD 1 TB NVMe SSD
Storage (Data) 2 TB HDD (RAID 1) 4 TB HDD (RAID 10) or SSD Array
Network Interface 1 Gbps Ethernet 10 Gbps Ethernet
Power Supply 750W Redundant 1000W Redundant

These specifications are subject to change based on the specific application requirements. Always refer to the Application Requirements Document before provisioning new servers. Consider using a Hardware Asset Management System to track server inventory.

Operating System and Software Stack

All servers in this category utilize a hardened Linux distribution. Currently, CentOS 7 is the standard, although migration to Rocky Linux is planned. The software stack is carefully curated to provide a stable and secure environment. See the Software Licensing Guide for details.

Software Version Purpose
Operating System CentOS 7 Base Operating System
Web Server Apache 2.4 Serving dynamic content
Database Server MariaDB 10.5 Data storage and retrieval
PHP 7.4 Server-side scripting
SSH Server OpenSSH 7.6 Secure remote access
Firewall Firewalld Network security
Intrusion Detection System Fail2ban Security monitoring and blocking

Regular Security Updates are critical. Automated patching is implemented using Ansible for consistent configuration management. Consult the Monitoring Dashboard for real-time system performance.

Configuration Details

Specific configuration settings are vital for maintaining the integrity and performance of the servers. These settings are managed through centralized configuration management tools. All changes must be documented in the Change Management System.

Configuration Item Value Description
Default SSH Port 2222 Non-standard port for enhanced security.
Firewall Rules Restrictive by default, allowing only necessary ports. See Firewall Configuration.
SELinux Enforcing Mandatory access control for enhanced security.
Log Rotation 7 days Logs are rotated weekly to prevent disk space exhaustion.
System Time Synchronization NTP Servers synchronize time using Network Time Protocol. See Time Synchronization.
Root Access Disabled via SSH Direct root login via SSH is disabled for security reasons. Use sudo.

Monitoring and Maintenance

Continuous monitoring is essential. Servers are monitored using Nagios and Grafana for performance metrics and availability. Regular maintenance tasks, such as disk space cleanup and log analysis, are scheduled and automated. Refer to the Disaster Recovery Plan in case of unforeseen issues. The Backup Strategy details how data is protected.
