LINUX OPERATIONS

Linux administration is more than installing a server

A Linux service depends on the interaction between its operating system, web server, runtime, database, storage, network, and access model. We start from observed symptoms and logs so that changes remain explainable and reviewable.

SERVICE CAPABILITIES

What Linux Infrastructure covers

Deploy and operate Linux servers and open-source services, from web and database stacks to hardening, monitoring, and practical troubleshooting for your environment.

Operating system & services

  • Server setup and maintenance

    Prepare the system, accounts, packages, and baseline settings for its role.

  • systemd and service health

    Review state, dependencies, startup behavior, and why a service stopped.

  • SSH and administration access

    Organize administrative access and keys around the organization’s policy.

Web and data stack

  • Nginx and Apache

    Handle virtual hosts, reverse proxy, TLS, and web-server errors.

  • Runtime and database

    Coordinate PHP and LAMP/LEMP components with MySQL, MariaDB, or PostgreSQL.

  • Storage and filesystems

    Investigate mounts, permissions, inodes, disk capacity, and growth.

Hardening and troubleshooting

  • Updates and packages

    Plan patches and dependencies with service compatibility in mind.

  • Logs and resource analysis

    Review load, memory pressure, network errors, and system events.

  • Operational integration

    Connect existing monitoring and backup practices to Linux workloads.

OPERATIONAL OUTCOMES

Practical outcomes for day-to-day service ownership

  • Clearer diagnosis

    System logs and resource signals are reviewed alongside service behavior.

  • Reviewable changes

    Important settings and dependencies are documented and staged.

  • Better capacity decisions

    Current usage and constraints inform the next infrastructure decision.

DELIVERY APPROACH

From environment discovery to operational handover

  1. 01

    Discover

    Record distribution, release, access, and server role.

    Map dependencies

    Review web, runtime, data, network, and backup dependencies.

  3. 03

    Plan the change

    Set sequence, validation, and rollback steps to match risk.

  4. 04

    Implement and validate

    Apply changes in stages and check service behavior.

  5. 05

    Document

    Hand over relevant settings and operating notes.

WHY SYSTECHNIC

Grounded in real server operations

From logs to cause

Web, access, network, and service failures are investigated from environment evidence.

The whole stack

The operating system and dependent services are considered together.

Distribution-aware

The approach follows the environment’s release and operational constraints.

FAQ

Linux infrastructure questions

Which Linux distributions do you support?

Ubuntu, Debian, and RHEL-family environments are assessed against release, software dependencies, and lifecycle. Exact scope is agreed after review.

Does this service include DevOps?

This page focuses on the operating system and Linux services. CI/CD design and deployment automation are covered by our DevOps service, and can be linked into the same operating model.

Can you troubleshoot Nginx or Apache errors?

Yes. Configuration, TLS, file access, upstream behavior, and logs are reviewed alongside runtime and network conditions.

What happens when a disk fills or load rises?

We first examine resource usage, inodes, processes, and event trends; corrective action follows the identified cause and risk.

Can workloads move between distributions?

Feasibility depends on application compatibility, package versions, data, and the change window, so it is assessed before implementation.

Is backup included?

We can assess requirements and coordinate with an existing backup solution. Backup policy design and restore testing belong to the separate Backup & Recovery service.
