Чтобы запускать административные задачи на Linux, у вас должны быть права суперпользователя (права root). В большинстве дистрибутивов Linux присутствует отдельная учетная запись суперпользователя, но в Ubuntu она по умолчанию отключена. Это позволяет предотвратить случайные ошибки и защитить систему от проникновения. Чтобы запустить команды, которые требуют административный доступ, используйте команду sudo .

Запуск прав суперпользователя командой sudo

Нажмите комбинацию клавиш Ctrl + Alt + T , чтобы открыть окно терминала. Так как в Ubuntu права суперпользователя по умолчанию отключены, вы не сможете воспользоваться командой su и получить административные права, как в прочих дистрибутивах Linux. [1] X Источник информации Вместо этого, вам сначала необходимо запустить команду sudo .

• Пример: команда sudo /etc/init.d/networking stop прекращает работу сети, а sudo adduser добавляет в систему нового пользователя. Обе эти команды требуют прав суперпользователя.
• Перед тем, как sudo выполнит команду, вы должны будете ввести пароль. Linux хранит пароль в течение 15 минут, так что вам не придется вводить их постоянно.

• Пример: введите gksudo gedit /etc/fstab , чтобы открыть файл «fstab» в текстовом редакторе GEdit с графическим интерфейсом.
• Если вы используете KDE Window Manager, вместо gksudo вводите команду kdesudo .

• Введите команду sudo passwd root . Этим вы создадите пароль для root, тем самым «включите» административный доступ. Смотрите, не забудьте этот пароль.
• Введите sudo -i . Введите пароль от root, когда это будет необходимо.
• Значок в терминале изменится с $ на # , указывая на то, что теперь вы обладаете правами суперпользователя.

Предоставьте доступ sudo другому пользователю. Если вы настраиваете учетную запись для того, кто в данный момент не имеет административного доступа, добавьте его имя в группу sudo. Для этого введите usermod -aG sudo username (замените «username» на правильное имя пользователя). [4] X Источник информации

How To Add a User and Grant Root Privileges on Ubuntu 18.04

Adding a user and granting that user root privileges is one of the many tasks of a system admin. Once a user has been added and granted root privileges they’ll be able to login to your Ubuntu VPS and perform vital functions for the upkeep of the system. Afterward, they’ll be able to use sudo before commands to perform elevated tasks. In this quick tutorial, we’ll show you how to add a new user and grant root permissions.

Preflight

• These instructions are intended specifically for adding a user on Ubuntu 18.04 LTS.
• We’ll be working from a Liquid Web Core Managed Ubuntu 18.04 LTS server, and I’ll be logged in as root.

Step 1: Add the Username

In my example, I’ll be adding my cat’s name, Tom, using the adduser command. Replace tom with your desired username. During this time, the system will also ask of me details from my user. Feel free to skip these details by pressing enter and eventually it asks us to confirm that the info is correct, leading us to a new user added.

Example Output:
Adding user `tom’ .
Adding new group `tom’ (1001) .
Adding new user `tom’ (1001) with group `tom’ .
Creating home directory `/home/tom’ .
Copying files from `/etc/skel’ .
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for tom
Enter the new value, or press ENTER for the default
Full Name []: Tom
Room Number []:
Work Phone []:
Home Phone []:
Other []:
Is the information correct? [Y/n] Y

Step 2: Grant Root Privileges to the User

The command above leads us to the /etc/sudoers.tmp file, where we can view the following code: # User privilege specification
root ALL=(ALL:ALL) ALL

After the root user line, you will add in your new user with the same format for us to grant admin privileges.

Once you’ve added the permission, save and exit the file by using the following process. (In Ubuntu 18.04, nano is the default editor, so we need to use the ctrl+x, y keystrokes to save and exit the file.)

hold `ctrl` and press `x`. At the prompt, press `y` and then hit `enter` to save and exit the file.

Step 3: Verify User Has Privileges

If you’ve followed the instructions correctly then this user will be able to run commands like, update, using the sudo:
