Despite the surge of NGINX, Apache is still one of the most used open source server software. But this article is not about Apache vs NGINX discussion. This is just a quick tips where I’ll show you various ways to restart Apache server in Ubuntu or other Linux distributions.
Restart Apache in Ubuntu Linux
Like many other services, there are multiple ways to restart Apache. Since Ubuntu 16.04, 18.04 and above versions use systemd, you can use the systemd commands to manage any service, including Apache. In fact, systemd is my recommend method.
But wait! Do you really need to restart Apache?
Why do you want to restart Apache server? Probably you made some configuration changes and you want those changes to take into effect. If that’s the case, you don’t need to restart Apache.
Restarting Apache means the Apache server will shutdown and then start again. If you are on a production server, it will result in downtime for all the services that utilize the Apache server. You don’t want to do that, do you?
Apache supports reload which means you can reload the configuration without shutting down the server. This way, your live server won’t suffer a downtime.
sudo systemctl reload apache2
If you don’t want to use systemd command, there is an alternate command to reload apache server:
sudo service apache2 reload
Okay! You really want to restart Apache
I can understand that you may have your reason where you reloading Apache won’t do the job and you must restart the Apache server. If that’s the case, you can use the systemd command:
sudo systemctl restart apache2
Alternatively, you can this command as well:
sudo service apache2 restart
Bonus Tip: Check status of Apache server
Since you are dealing with restarting and reloading a service, it would be a good idea to check its status. You can check the status of Apache server using systemd:
systemctl status apache2.service
The non-systemd command for checking Apache server status is:
service apache2 status
