Final answer:
To start Apache on Ubuntu, use 'sudo systemctl start apache2'. Ensure Apache is installed with 'sudo apt-get install apache2'. Check its status with 'sudo systemctl status apache2' and enable it at boot with 'sudo systemctl enable apache2'.
Step-by-step explanation:
To start the Apache server on Ubuntu, you can use the following command in the terminal:
sudo systemctl start apache2
Before doing so, make sure you have Apache installed. If not, you can install it using:
sudo apt-get update
sudo apt-get install apache2
Once the Apache server is running, you can check its status to ensure it started correctly:
sudo systemctl status apache2
If Apache is configured to start at boot time, it will automatically start during system boot. If you want to enable this feature, use the command:
sudo systemctl enable apache2
This command sets up a symbolic link between the Apache service script and the system’s startup folders, ensuring that the server starts when the system does. Remember, proper management of a web server requires attention to security and configuration details beyond starting the server.
