Server Setup & Configuration

Production-Ready Servers, Configured Right From Day One

A reliable, high-performance server is the foundation of every successful application. At Renux Technologies, we provide comprehensive server setup and configuration services that transform bare metal or cloud instances into fully production-ready environments — hardened against threats, optimised for your workload, and configured to run your application stack with maximum efficiency. We don't just install packages and call it done; we build server environments that are secure, reproducible, and built to last.

Every server we provision follows a rigorous, repeatable process. We begin with operating system installation and hardening — disabling unnecessary services, applying the latest security patches, and configuring kernel parameters for your specific workload. From there, we install and tune web servers (Nginx, Apache, or Caddy), configure database servers (MySQL, PostgreSQL, MongoDB), set up application runtimes (PHP-FPM, Node.js, Python with Gunicorn), and implement SSL/TLS with automated certificate renewal. Every configuration decision is documented and version-controlled, so your infrastructure is never a mystery.

Security is woven into every step of our server setup process. We configure firewall rules using UFW or iptables, deploy fail2ban to block brute-force attacks, enforce SSH key-only authentication, restrict user permissions to the principle of least privilege, and configure audit logging to track all system-level changes. We also set up automated security updates for the operating system so critical patches are applied promptly without manual intervention.

Performance tuning is equally important. We optimise swap and memory settings, configure OPcache for PHP environments, tune connection pooling for database servers, set up proper log rotation to prevent disk exhaustion, and configure environment variables securely. Whether you're deploying a single application server or a multi-tier architecture, every server we configure is built for reliability, security, and performance from the moment it goes live.

What's Included

• OS Installation & Hardening: Clean installation of Ubuntu, Debian, CentOS, or AlmaLinux with CIS benchmark hardening, kernel parameter tuning, and removal of unnecessary packages and services
• Web Server Setup: Installation and configuration of Nginx, Apache, or Caddy with virtual host configuration, gzip compression, connection limits, and HTTP/2 support
• Database Server Configuration: MySQL, PostgreSQL, or MongoDB setup with optimised buffer sizes, connection pooling, query caching, and automated backup schedules
• Runtime Environment Setup: PHP-FPM, Node.js, Python (with Gunicorn/uWSGI), Ruby, or Java runtime installation and version management using tools like nvm, pyenv, or phpbrew
• SSL/TLS Configuration: Let's Encrypt or commercial certificate installation, automated renewal via Certbot, HSTS headers, OCSP stapling, and A+ SSL Labs rating configuration
• Firewall Configuration: UFW or iptables rule setup, port restriction, rate limiting, and network segmentation to minimize attack surface
• Fail2ban & Intrusion Prevention: Brute-force protection for SSH, web applications, and email services with customised jail configurations and ban thresholds
• SSH Hardening: Key-only authentication, root login disablement, port customisation, idle timeout configuration, and IP-based access restrictions
• Environment Variables & Secrets: Secure configuration of application environment variables, dotenv file management, and integration with secret management tools (Vault, AWS Secrets Manager)
• Log Configuration & Rotation: Centralised logging setup with logrotate configuration, syslog forwarding, and structured logging for application and system logs
• Swap & Memory Tuning: Swap file or partition configuration, vm.swappiness tuning, OOM killer configuration, and memory limit enforcement for applications

• Monitoring: Netdata, Prometheus Node Exporter, Monit for service health checks

Our Server Setup Process

1. Requirements Gathering

We begin by understanding your application stack, expected traffic patterns, compliance requirements, and performance targets. This allows us to select the right instance type, operating system, and configuration parameters for your workload.

2. Provisioning & Hardening

Using infrastructure-as-code tools, we provision your server, apply OS hardening, install required packages, and configure security measures. Every step is codified in version-controlled playbooks, ensuring the setup is reproducible across development, staging, and production environments.

3. Application Stack Configuration

We install and configure your full application stack — web server, database, runtime, caching layers, and message queues — with performance tuning tailored to your expected load and resource constraints.

4. Testing & Handover

Before handover, we run security scans, verify SSL configurations, test firewall rules, and perform basic load testing. You receive full documentation of the server configuration, credentials, and maintenance procedures.
