Linux Server Management & Configuration
Linux Server Management, Configuration & Support — Every Distribution
We’ve been working with Linux since 1998 — real hands-on experience from the days of hand-compiled kernels and text-only installs, through to today’s cloud instances and containers. That’s more than 25 years of building, securing, tuning and rescuing Linux servers, and it’s the backbone of our own hosting, email and VoIP infrastructure. When you hand your server to Mobile Techs, you’re not getting someone who read a tutorial last week; you’re getting someone who has run production Linux systems for decades.
We manage and configure servers across every major distribution — Debian, Ubuntu, Red Hat, Rocky, AlmaLinux, CentOS, Fedora, SUSE, Arch, Gentoo, Slackware and the BSDs — whether it’s a single VPS, a dedicated box in a data centre, a cloud instance, or a rack of physical servers. New build, ongoing management, a one-off fix, or a full migration: we work in plain English, document what we do, and leave your systems in a better state than we found them. Get in touch for a free consultation.
Distributions & Platforms We Work With
Debian & Ubuntu
The most common server distributions we deploy — rock-solid Debian and Ubuntu LTS releases, from bare install through to fully configured, secured and patched production servers.
Red Hat, Rocky, Alma & CentOS
Enterprise RHEL-family systems — Red Hat Enterprise Linux, Rocky Linux, AlmaLinux, CentOS and Fedora — including migrations off end-of-life CentOS onto a supported replacement.
SUSE, Arch, Gentoo & More
SUSE and openSUSE, plus the more specialised distributions — Arch, Gentoo, Slackware and others. If it’s Linux, we can work with it, whatever package manager it uses.
BSD & Unix-Like Systems
Not strictly Linux, but right at home for us — FreeBSD, OpenBSD and other Unix-like systems for firewalls, routers and high-reliability server roles.
Cloud, VPS & Dedicated
AWS, Azure, Google Cloud, DigitalOcean, Linode, Vultr and self-hosted — cloud instances, virtual private servers, and physical dedicated hardware in the data centre or on your premises.
Containers & Virtualisation
Docker, Podman, LXC/LXD containers, plus KVM, Proxmox and VMware virtualisation — consolidating workloads and isolating services cleanly on the one host.
Server Setup & Configuration
Fresh Builds & Provisioning
New servers built to spec from the ground up — partitioning, LVM, RAID, filesystem choice, user and SSH key setup, and a hardened base image ready for its role.
Migrations & Upgrades
Move servers between hosts, data centres or cloud providers with minimal downtime, and safely upgrade across major distribution releases without breaking what’s running.
Automation & Config Management
Repeatable, documented infrastructure using Ansible, shell scripting and cron — so your servers are consistent, reproducible, and not a mystery held together by one person’s memory.
Networking & VPNs
Static routing, bridging, VLANs, WireGuard and OpenVPN tunnels, site-to-site links and secure remote access — configured properly and documented.
Services We Run & Manage
Web Servers
Apache, Nginx, LiteSpeed and Caddy — virtual hosts, reverse proxies, PHP-FPM, and free auto-renewing Let’s Encrypt SSL certificates. Tuned for speed and stability.
Databases
MySQL, MariaDB, PostgreSQL, Redis and SQLite — installation, tuning, replication, and reliable automated backups you can actually restore from.
Mail Servers
Postfix, Dovecot, Exim and full mail stacks with SPF, DKIM, DMARC, spam filtering and anti-virus — deliverability that lands in the inbox, run on our own infrastructure for years.
DNS, VoIP & More
BIND and PowerDNS name servers, Asterisk and FreePBX VoIP systems, Samba file shares, FTP/SFTP, Git servers and just about any Linux service you need running reliably.
Security & Hardening
Firewalls & Hardening
iptables and nftables firewalls, fail2ban, SSH lockdown, SELinux/AppArmor, kernel hardening and sensible defaults — closing the doors that automated attacks come knocking on. See also our Website & Server Security service.
Audits & Remediation
Vulnerability assessment, patch review and remediation — pairing neatly with a Remote Security Audit so exposure is graded before and after we harden the box.
Access Control & SSH
Key-based SSH, multi-factor authentication, per-user permissions, sudo policies and jump hosts — so the right people get in and nobody else does.
Certificates & Encryption
TLS/SSL certificates, encrypted volumes (LUKS), and secure key management — data protected in transit and at rest.
Ongoing Management & Support
Patching & Updates
Scheduled security patching and package updates, tested and applied carefully — keeping your server current without the 3am surprise of an update that breaks production.
Monitoring & Alerting
CPU, memory, disk, services and uptime watched around the clock with our monitoring service — problems caught and often fixed before you notice.
Backups & Disaster Recovery
Automated, tested off-site backups and a recovery plan that actually works — snapshots, rsync, Borg/Restic and full bare-metal restore when it counts.
Troubleshooting & Rescue
Server won’t boot, disk full, service down, or compromised? We diagnose and recover Linux systems — from a slow website to a full rescue-mode filesystem repair.
Performance Tuning
Profiling and tuning slow servers — kernel parameters, database queries, web server workers, caching and I/O — to get more out of the hardware you already have.
Managed Contracts
Hand it over entirely with a Managed IT contract — patching, monitoring, backups and priority support for a predictable monthly cost, with the after-hours emergency line for critical issues.
Whether you need a server built, a fire put out, a migration handled, or someone reliable to keep everything patched and running, we’ve been doing exactly this since 1998. Contact us to talk through what you need — no jargon, no obligation.
