Как изменить Hostname (имя компьютера)

Hostname (имя компьютера, имя хоста) задается во время установки системы Linux. Hostname определяет название компьютера и используется преимущественно для идентификации компьютера в сети. Нельзя назначать два одинаковых Hostname для компьютеров в одной сети.

Просмотр текущего Hostname

Чтобы показать текущий Hostname можно использовать команду hostname без параметров:

Также Hostname можно отобразить командой hostnamectl :

Как изменить Hostname

Рассмотрим, как изменить Hostname двумя разными способами.

Способ 1. Используем команду hostnamectl

Во многих systemd-based дистрибутивах (например, в Ubuntu Linux) есть утилита hostnamectl .

Воспользуемся командой hostnamectl , чтобы установить новое значение Hostname равным pingvinus . Используется аргумент set-hostname:

sudo hostnamectl set-hostname pingvinus

Способ 2. Редактируем файлы /etc/hostname и /etc/hosts

Еще один способ изменения Hostname — это ручное редактирование файла /etc/hostname и файла /etc/hosts .

Сначала выполните команду (вместо pingvinus укажите свое значение):

Отредактируем файл /etc/hostname для редактирования в редакторе nano, выполняем команду:

Измените текущее значение в файле на новое. Сохраните изменения и закройте файл. Это можно сделать, нажав Ctrl+C , затем Y и Enter .

Hostname прописывается также в файле /etc/hosts , поэтому нужно изменить его значение в этом файле. Откроем файл:

Найдите строку вида « 127.0.0.1 ваш_hostname » и впишите новое имя хоста. Сохраните изменения и закройте файл.

Проверка результата

Чтобы проверить, изменилось ли значение Hostname, откройте новое окно терминала и введите команду:

How to Change the Computer Name (Hostname) in Linux Mint 20

This is a beginner’s guide shows how to change the computer name (hostname) in Linux Mint 20.

In Linux world, the computer name is called hostname. It’s a label that is assigned to a device connected to a computer network and that is used to identify the device in various forms of electronic communication.
Hostnames may be simple names consisting of a single word or phrase, or they may be structured.

Change the hostname / computer name for temporary use:

There’s a hostname Linux command allows to change your computer name easily. And it works until reboot.

Open terminal and run command:

sudo hostname NEW_NAME_HERE

In the case, I set the name to ulyana via command sudo hostname ulyana .
You can then check the computer name via hostname command. And the new name will be displayed after @ in new terminal window.

Change the hostname / computer name permanently:

There are a few ways to change the name permanently. It may be different for each desktop environment. For the universal way, you can edit the /etc/hostname configuration file.

Open terminal and run command to edit the file with Linux Mint Cinnamon’s default xed text editor. You may replace xed depends on your DE.

When the file opens, replace the content with your new name and save it.
Also edit the /etc/hosts file and set the new name to avoid networking issue.

How to change hostname in Linux Mint?

The hostname is the name of your computer. It is generally used to identify your PC on the network and it’s also usually part of the command prompt in Linux terminal.

The hostname is assigned to the computer during the operating system installation, but you can change it later, if you want. In this post we will see how you can change hostname of your Linux Mint PC.

Before we start

To find the current hostname of your Linux PC simply open the terminal and run the following command:

The image below is from my home Linux Mint VM and its hostname is old-hostname :

Notice that the current hostname is also the part of the command prompt, which includes:

Now, let’s see how we can change the hostname.

Method #1. Use hostnamectl ( recommended)

The recommended way is to use hostnamectl command which is a part of systemd. It means that you can use this method on any Linux distribution running systemd.

If you run hostnamectl in the Terminal you will see some information about your system including the hostname:

To change the hostname run:

As you can see on the image below the hostname has been changed:

Method #2. Use hostname command

This method is a bit longer and not as convenient as the first one, because it requires more work. Nevertheless, I decided to describe it here, because it involves a manual editing of /etc/hostname system file and it’s useful to be aware of its existence.

You can run the following command to set the new hostname(temporary):

After running this command the hostname will be changes, but if you reboot the PC, it will revert back to the previous hostname. The reason for this is that the permanent hostname of the machine should be specified in the /etc/hostname file. In the previous Method #1 it was done automatically by the hostnamectl command, but here we need to do this manually.

Use any text editor to edit the file and make sure it contains a single line which is the new hostname. You will need sudo privileges to edit this file, so if you use nano editor, run the command:

I edited the file to look like this:

Now, after the reboot the hostname will be set to new-hostname

/etc/hosts file

Another important file which you should edit is /etc/hosts file which is used for hostname resolution. Whenever your Linux PC wants to reach another machine on the local network or the Internet it’s going to look for the matching name in this file. Since you haven’t edited this file it will contain the old hostname resolving to a loopback address. This means that you will be able to ping your PC via the old name, even after you change the hostname, which is confusing.

Therefore, let’s edit it too:

After the change it look like this:

After you change it to the correct hostname and save the file you will not be able to ping the old hostname anymore which is what we want.

Now you can reboot the PC and after the reboot the new hostname will be preserved.

Conclusion

Thank you for reading. I hope this was helpful 🙂
