otus-task5's Introduction

Домашнее задание: развернуть сервис NFS и подключить к нему клиента

Решение:

Задание выполнено на машине vagrant с помощью Ansible.

Скрипт deploy.sh:

  • создаёт две виртуальные машины с помощью Vagrantfile;
  • заускает роли:
    • manage_nfss (настройка сервера);
    • manage_nfsc (настройка клиента);
    • test (тестирование результата);
  • получает лог из виртуальной машины.

Файлы с логами, полученными после отработки ролей находится в директории со скриптом deploy.sh

Лог настройки сервера 
 Посмотрим прослушиваемые порты (ss -tnplu)
