Restart service linux server

2. Start a service

To start a service in Linux, you just need to use its name like this:

3. Stop a service

To stop a systemd service, you can use the stop option of systemctl command:

4. Restart a service

To restart a service in Linux with systemd, you can use:

5. Check the status of a service

You can confirm that you have successfully executed a certain action by printing the service status:

This will output information in the following manner:

That was systemd. Let’s switch to init now.

Method 2: Managing services in Linux with init

The commands in init are also as simple as system.

1. List all services

To list all the Linux services, use

The services preceded by [ – ] are disabled and those with [ + ] are enabled.

2. Start a service

To start a service in Ubuntu and other distributions, use this command:

3. Stop a service

Stopping a service is equally easy.

4. Restart a service

If you want to restart a service, the command is:

5. Check the status of a service

Furthermore, to check if your intended result was achieved, you can output the service status:

This will output information in the following manner:

This will, most importantly, tell you if a certain service is active (running) or not.

Wrapping Up

Today I detailed two very simple methods of managing services on Ubuntu or any other Linux system. I hope this article was helpful to you.

Как запустить, остановить и перезапустить сервисы в Linux

Linux обеспечивает детальный контроль над системными службами через systemd с помощью команды systemctl. Службы могут быть включены, выключены, перезапущены, перезагружены или даже включены или отключены при загрузке. Если вы используете Debian, CentOSили Ubuntu, ваша система, вероятно, использует systemd.

Это руководство покажет вам, как использовать основные команды для запуска, остановки и перезапуска служб в Linux.

Базовый синтаксис команды systemctl

Основной синтаксис для использования команды systemctl:

systemctl [command] [service_name]

Как правило, вам нужно запускать это как суперпользователь поэтому команды будут начинаться с sudo.

Как проверить, работает ли служба в Linux

Чтобы проверить, активна ли служба или нет, выполните следующую команду:

sudo systemctl status SERVICE_NAME

Замените SERVICE_NAME на нужный сервис.

В нашем случае мы будем брать за пример веб-сервер Apache.

Интересный факт: в Ubuntu и других дистрибутивах на основе Debian служба Apache называется apache2. В CentOS и других дистрибутивах RedHat служба Apache называется httpd или httpd.service

sudo systemctl status apache2

Так мы проверили состояние Apache. Выходные данные показывают, что служба активна (работает), как на рисунке ниже:

Как перезапустить сервис

Чтобы остановить и перезапустить службу в Linux, используйте команду:

sudo systemctl restart SERVICE_NAME

Где SERVICE_NAME — имя вашего сервиса.

После выполнения команды ваш сервис должен снова заработать. Вы можете проверить состояние с помощью команды status

Для перезапуска нашего сервера Apache используем:

sudo systemctl restart apache2

Как перезагрузить конфигурационные файлы сервиса

Чтобы служба перезагрузила свои файлы конфигурации, введите в терминале следующую команду:

sudo systemctl reload SERVICE_NAME

После перезагрузки проверьте ее состояние командой status для подтверждения.

В нашем примере мы перезагрузили Apache, используя:

sudo systemctl reload apache2

Как запустить сервис

Чтобы запустить службу в Linux вручную, введите в терминале следующее:

sudo systemctl start SERVICE_NAME

Например, команда для запуска службы Apache:

sudo systemctl start apache2

Как остановить сервис

Чтобы остановить активную службу в Linux, используйте следующую команду:

sudo systemctl stop SERVICE_NAME

Для нашего апача используем команду

sudo systemctl stop apache2

Проверьте, остановился ли сервис с помощью команды status . Вывод должен показать, что сервис неактивен — inactive (dead)

Как включить сервис при загрузке

Чтобы настроить службу для запуска при загрузке системы, используйте команду:

sudo systemctl enable SERVICE_NAME

Чтобы включить Apache при загрузке системы, выполните команду:

sudo systemctl enable apache2

Как отключить сервис при загрузке

Вы можете запретить запуск службы при загрузке с помощью команды:

sudo systemctl disable SERVICE_NAME

sudo systemctl disable apache2

How to Restart Services in Linux

This article was co-authored by wikiHow staff writer, Jack Lloyd. Jack Lloyd is a Technology Writer and Editor for wikiHow. He has over two years of experience writing and editing technology-related articles. He is technology enthusiast and an English teacher.

The wikiHow Tech Team also followed the article’s instructions and verified that they work.

This article has been viewed 469,101 times.

This wikiHow teaches you how to force a currently running service to restart in Linux. You can do this with just a few simple commands regardless of your Linux type.

• Since Linux distributions vary in appearance from release to release, you may have to look for the «Terminal» or command line app inside of a folder in the Menu.
• You may find the «Terminal» app on the desktop or in the toolbar at the bottom of the screen instead of in the Menu.
• Some Linux distributions have a command line bar at the top or bottom of the screen.

Find the command name of the service that you want to restart. You’ll typically find the name of the service (e.g., «Apache») on the left side of the screen, while the command name (e.g., «httpd» or «apache2», depending on your Linux distribution) will appear on the right side.

• For example, to restart Apache on Ubuntu Linux, you would type sudo systemctl restart apache2 into Terminal.

• If the service doesn’t restart after doing this, try typing in sudo systemctl stop service , pressing ↵ Enter , and then entering sudo systemctl start service .

Community Q&A

It means both, actually. If you’re talking about hard drives and storage, SSHD is correct for solid state hybrid drive. If you’re talking about Linux, the Secure Shell Daemon is also correct.

To see a comprehensive list of all current services in all directories on your computer, enter ps -A into Terminal.

Don’t stop services at random while trying this out. Some of the services listed are necessary to keep your system stable and running happily.

How to Restart Service in Linux

You can use the restart command to restart Systemd services. This command stops the service and then starts it back. Or it just starts the service if it is not running. For example, you can restart the Nginx web server using this command:

sudo systemctl restart nginx

If everything is okay, the command will output nothing. But if an error occurs while the process is stopped or started, an error message will be displayed.

When you want to restart the service only if it is running use the try-restart command:

sudo systemctl try-restart nginx

The Systemd initialization system supports not only services restarting, when the services are entirely stopped but also soft reloading. In this case, the service continues working without downtime and only updates its configuration from configuration files. You can use this reloading by entering the reload command:

sudo systemctl reload nginx

This method is not supported by all services. If you don’t know whether a specific service supports reloading but still want to restart it, use the reload-or-restart command. For example:

sudo systemctl reload-or-restart nginx

This command will use soft reloading if it is supported. But if it is not, the service will be restarted in the usual way. You can read more about service management in Linux in this article.
