To start the Apache web server via SSH, you can use the systemctl start apache2 command.
To stop the Apache web server, use the systemctl stop apache2 command.
To restart the Apache web server, use the systemctl restart apache2 command.
Note: These commands assume that Apache is installed and configured to run as a service on your system. The exact name of the service may vary depending on your Linux distribution and the version of Apache you are using.
You may also need to use sudo to run these commands, depending on your user's permissions. For example: sudo systemctl start apache2.
Alternatively, you can use the service command to start, stop, or restart Apache. For example: service apache2 start, service apache2 stop, or service apache2 restart.
Keep in mind that these commands may not work on all systems, as the service command has been deprecated in some distributions in favor of systemctl.
