swdream / Tại sao không đặt log files trong root partition
Last active August 27, 2018 08:58
1. Root partition là data partition quan trọng nhất trong Linux enterprise and Unix system và là non-swap filesystem duy nhất được
được yêu cầu trong quá trình boot một unix hay linux system.
2. Root partition được mount tới root directory - the root filesystem của linux/unix system.
3. Root filesystem chứa các thư mục/file được yêu cầu để boot linux/unix system:
- thư mục mà qua đó các devices access (/dev)
- thư mục chứa các initialization và config file (/etc)
- thư mục chứa các libraries, system modules, security ... (/lib)
- thư mục chứa các file system binaries (/bin,/sbin)
Lý do khi có một file log lớn, khi đó sẽ làm root partition bị full.

Concepts:

  • groups: set of hosts
  • facts: contains all info about remote host.
  • Ansible facts are a way of getting data about remote systems for use in playbook variables.
1. these operating systems, Ansible will fallback into using a high-quality Python implementation of OpenSSH called ‘paramiko’.
2. By default, ansible read remote hosts in /etc/ansible/hosts, it is an inventory file.
