Abstract ─ YS910 is a Linux system administration document. It details system administration tasks and operations, including verification results. The target distribution covered in the document is AlmaLinux 9/10, which supports Red Hat Enterprise Linux (RHEL) compatible distributions. The document provides a concise command cheat sheet and explains efficient workflows. It also documents setup procedures to ensure reproducibility. The goal of this project is to reduce working time, improve operational efficiency, and smooth out system deployment.
Abstract ─ YS0 is an Ansible playbook. This playbook builds a working environment on a Red Hat Enterprise Linux-based distribution, including the installation of Ruby, various servers, and additional tools. By applying a pre-defined playbook, it eliminates errors and inconsistencies that occur with manual configuration. It is an idempotent playbook. It manages the infrastructure state as code. It uses the version control system Git. It ensures reproducibility through idempotency and version control.
Keywords:
Ansible, Git, IaC(Infrastructure as Code)
