To gracefully reboot the Apache web server from the shell, you can use the apachectl command with the -k graceful option.
Here is an example of using the apachectl command to gracefully reboot the Apache web server:
sudo apachectl -k graceful
This command will reload the Apache HTTPD configuration file and gracefully restart the Apache service, without interrupting any active connections or requests.
Keep in mind that the exact syntax and options for the apachectl command may vary depending on your specific Apache installation and configuration. It is always a good idea to refer to the official Apache documentation for detailed instructions and further information.
