Kiosk

Киоск на базе пустого образа Alt jeos

Обновление ОС и ядра

В этом разделе всё делается в рутовой консоли. Т.к. sudo по умолчанию в ОС Альт не присутствует (ниже мы его добавим)

Установка необходимых пакетов через apt-get

apt-get install nano xorg xorg-server xorg-server openssh sudo su xterm gnome3-minimal xhost awesome git npm

Установка браузера google-chrome через epm

epm play chrome

Установка необходимых пакетов через npm

npm install -g n

Установка LTS версии платформы nodejs и её пакетного менеджера npm

n lts

Создание пользователя kiosk

useradd kiosk

установка пароля делается командой

passwd kiosk

делаем sudo su без пароля для пользователя kiosk. Просто бросьте это в рутовую консоль:

cat << EOF > /etc/sudoers
User_Alias	WHEEL_USERS = %wheel
User_Alias	XGRP_USERS = %xgrp
Defaults:XGRP_USERS env_keep += "DISPLAY XAUTHORITY"

kiosk ALL=(ALL) NOPASSWD: ALL
