WALKTHROUGHS ARE OPEN

Training centerOnly what you can use

Hands-on walkthroughs: monitoring, containers, a Linux domain, virtualization, databases. Each one is a path you can follow — commands, configs, checks and what to take away. No filler.

Everything lives on AdminGuide.online. We write from our own production work, so nothing here is untested.

  • Every walkthrough is taken to a working result, not to a pretty slide.
  • Written by engineers who run production and answer for it at night.
  • Material is linked into series: from what it is to installing, checking and concluding.
MANIFESTO

The system does not ask whether you are ready.It goes down at night, on a Friday, in production.In that minute nobody cares how many certificates you hold.What matters is what your hands do in the first ten minutes.Slides do not teach that. Walkthroughs, commands and a verified result do.We built the place where that is taught.

KEPT CURRENTZabbix 8 or Ubuntu Server 26 ships — we redo the walkthrough instead of leaving the old version up.

PRINCIPLES

This is what we stand on

  1. 01

    An example beats theory

    a concrete task, the commands and a verified result.

  2. 02

    We write what we have done ourselves

    production first, the walkthrough after.

  3. 03

    We finish the job

    install, configure, verify and conclude, never «you take it from here».

  4. 04

    We follow the versions

    a new one ships, we rewrite the walkthrough instead of pointing at the old one.
