Linux Administration
Linux Server Administration — Ubuntu, Debian, AlmaLinux, CentOS
Linux is the foundation of most web infrastructure worldwide — and the primary operating system we deploy for our clients' servers. We have been administering servers running Ubuntu Server, Debian, AlmaLinux, and CentOS for years, in production environments hosting WordPress sites, WooCommerce stores, and custom web applications. We configure servers from scratch, harden the operating system, deploy firewalls, design backup strategies, and monitor infrastructure 24/7. Every Linux server we deliver is tailored to the specific requirements of your application — we do not rely on templates or default configurations.
System
Linux Installation & Configuration
We install and configure Linux servers from scratch — selecting the distribution based on project requirements, configuring partitioning, filesystem, networking, package repositories, and core system services. Ubuntu Server and Debian for WordPress web environments, AlmaLinux as a stable CentOS successor for production workloads requiring long-term support.
Hardening
Operating System Hardening
We secure Linux servers with a multi-layered approach: system and kernel updates, disabling unnecessary services and daemons, configuring iptables or nftables firewall, restricting SSH access to public key authentication only, deploying fail2ban, configuring AppArmor or SELinux, setting password policies, and auditing file permissions. Each layer reduces the attack surface.
Firewall
iptables / nftables Firewall & fail2ban
We configure kernel-level firewalls on Linux — iptables for older distributions, nftables for newer ones. We define traffic filtering rules, close unused ports, and segment access to services. We deploy fail2ban for automatic blocking of brute-force attempts on SSH, FTP, admin panels, and other listening services.
Web Server
Nginx, Apache & PHP-FPM for WordPress
We configure and optimize web servers on Linux for WordPress and WooCommerce: Nginx with FastCGI cache, Apache with mod_rewrite and MPM event, PHP-FPM with dedicated pools per site. Redis or Memcached as object cache, OPcache for compiled PHP bytecode. We tune worker_processes, keepalive, buffers, and limits for your specific workload.
Backup
Backup & Disaster Recovery
We design and implement backup strategies on Linux servers using rsync, borgbackup, restic, or provider snapshots. Local and remote (offsite) copies with AES-256 encryption and retention rotation. We regularly test recovery procedures — a backup you have not tested is not a backup.
Monitoring
24/7 Monitoring & Updates
We monitor Linux servers around the clock: availability, CPU load, RAM usage, disk and partition utilization, network traffic, system and application service status. Alerts are sent immediately — we respond to issues before they affect your website. We perform regular security updates for the OS and all software.
A Linux server is not something you set up and forget about. It is a living infrastructure that requires regular updates, monitoring, log reviews, and responses to evolving threats. Every server we manage is tailored to the specific requirements of the application — we do not copy configurations from Stack Overflow and hope for the best.
