How to Set Up an Apache Web Server on Ubuntu

How to Set Up an Apache Web Server on Ubuntu: If you are looking to host your website or just experiment with a web server, Apache is one of the most popular options out there. It’s reliable, open-source, and works seamlessly on Ubuntu. In this guide, I will practically show you how to install and set up an Apache web server on the Ubuntu system in the simplest way possible.

Whether you’re a beginner or just need a refresher, this step-by-step guide will make the whole process easy and approachable.

I am sure, you will not feel any difficulty in following my instructions to Install Apache on your machine.

So are you ready now?

Step 1: Update Your System

Before we begin, it’s always a good idea to ensure your system is up to date. If you update your system before installing any application then It helps to avoid any compatibility issues.

Run the following command to update and upgrade your Ubuntu System:

Command:

sudo apt update && sudo apt upgrade

What this does:

• sudo apt update fetches the latest package lists from Ubuntu’s repositories.
• sudo apt upgrade upgrades any outdated packages.

By doing this, you make sure that when you install Apache, it uses the latest version available.

Step 2: Install Apache

With your system updated, the next step is to install Apache itself. Ubuntu comes with Apache in its default software repositories, so the installation process is simple. Run the following simple command on your Ubuntu terminal:

Command:

sudo apt install apache2

Once the installation is complete, Apache will start automatically. You don’t need to do anything special at this point. However, you can verify if Apache is running properly with the next step.

Step 3: Verify Apache Installation

You may want to make sure Apache is installed and running without issues. Right? So run the following command to verify:

Command:

sudo systemctl status apache2

If it’s running, you should see an output that says active (running). If it’s not running for some reason, you can start it buy running the following command on your terminal:

Command:

sudo systemctl start apache2

Now, let’s check if Apache is truly working by visiting your server’s IP address in a web browser. You should see the default Apache welcome page that says “It works!”

Don’t you know how to find the IP address of your system? No worries, I will guide you to find it.

Tip: How to Find Your Server’s IP Address

If you want to check the IP address of your system then you can use this command to find the IP address of your server:

hostname -I

Copy and paste that IP into your browser, and you’re good to go.

Step 4: Configure the Firewall

Most Ubuntu installations come with ufw (Uncomplicated Firewall). To allow web traffic through the firewall, you’ll need to adjust some settings.

Commands to open the firewall for Apache:

sudo ufw allow 'Apache'
sudo ufw enable
sudo ufw status

After running these commands, ufw will allow HTTP and HTTPS traffic, ensuring that visitors can access your website.

Step 5: Set Up Virtual Hosts (Optional)

Apache uses virtual hosts to handle multiple domains or websites on the same server. If you’re planning to host multiple sites, setting up virtual hosts will help.

Let’s assume you want to set up a site called example.com. Here’s how to create a virtual host for that domain.

1. Create a directory for your website:

   sudo mkdir -p /var/www/example.com

2. Set the appropriate permissions:

   sudo chown -R $USER:$USER /var/www/example.com

3. Create a configuration file for your virtual host: Use a text editor like nano to create the configuration file.

   sudo nano /etc/apache2/sites-available/example.com.conf

4. Add this content to the file:

   <VirtualHost *:80>
       ServerAdmin [email protected]
       ServerName example.com
       ServerAlias www.example.com
       DocumentRoot /var/www/example.com
       ErrorLog ${APACHE_LOG_DIR}/error.log
       CustomLog ${APACHE_LOG_DIR}/access.log combined
   </VirtualHost>

5. Enable the virtual host:

   sudo a2ensite example.com.conf

6. Disable the default configuration (optional):

   sudo a2dissite 000-default.conf

7. Restart Apache:

   sudo systemctl restart apache2

At this point, you’ve successfully set up a virtual host on your Apache server. You can now add more websites following these steps.

Table: Key Apache Commands Overview

Command	Description
sudo apt install apache2	Installs Apache web server
sudo systemctl status apache2	Checks if Apache is running
sudo ufw allow 'Apache'	Allows HTTP and HTTPS traffic through firewall
sudo a2ensite <site>	Enables a virtual host configuration file
sudo a2dissite <site>	Disables a virtual host configuration file
sudo systemctl restart apache2	Restarts the Apache service

Step 6: Test Your Setup

Now that everything is in place, it’s time to test your Apache server. Open your browser and navigate to the IP address of your server or the domain name if you have set up a virtual host.

If everything is set up correctly, you should see your default or custom webpage.

Troubleshooting Tips:

• If your webpage doesn’t load, check that Apache is running with sudo systemctl status apache2.
• Make sure the correct permissions are set for your website directory.
