Introduction
Welcome to our comprehensive guide on how to set up Apache Web Server on Ubuntu. Whether you’re a website owner, developer, or newcomer to the world of web servers, this guide is designed to give you an in-depth understanding of Apache Web Server and how to install it on Ubuntu.
Apache is the most widely used web server on the internet, and it’s known for its reliability, scalability, and security. Its popularity is owed to its open-source nature, which allows developers to customize it according to their needs without any restrictions.
Apache can run on a variety of operating systems, but in this guide, we’ll focus on setting it up on Ubuntu, a popular Linux-based operating system.
So, whether you’re looking to host a website, run an application, or simply learn something new, let’s get started with the ultimate guide on setting up Apache Web Server on Ubuntu.
What is Apache Web Server?
Apache is a free, open-source web server software that allows you to host websites and web applications. It’s developed and maintained by the Apache Software Foundation and is known for its stability, security, and flexibility. Apache Web Server is currently used by over 50% of all active websites on the internet, making it the most popular web server on the planet.
Why Apache Web Server on Ubuntu?
Ubuntu is a popular choice for web server hosting due to its stability, security, and ease of use. As an open-source operating system, Ubuntu is free to use and comes with all the necessary software pre-installed. Additionally, it has a large and active community, which means you can easily find support and resources to help you troubleshoot any issues. Apache Web Server is also free and open-source, making it a natural fit for Ubuntu.
Prerequisites
Before we start the installation process, you need to make sure that:
Prerequisites |
Commands |
|---|---|
Ubuntu installed |
sudo apt-get update |
User with sudo privileges |
adduser [username] |
Open ports 80 and 443 |
sudo ufw allow 80/tcp && sudo ufw allow 443/tcp |
Setting Up Apache Web Server on Ubuntu
Step 1: Update Ubuntu
The first step is to update Ubuntu using the following command:
sudo apt-get update
This command will update all the available packages and dependencies.
Step 2: Install Apache Web Server
Now that we’ve updated Ubuntu let’s install Apache Web Server using the following command:
sudo apt-get install apache2
This command will start the installation process, and you’ll be prompted to confirm the installation.
Step 3: Configure Firewall
By default, Apache listens on port 80, which is an unsecured port. So, it’s essential to enable the firewall to allow traffic to come through on port 80. To enable the firewall, use the following command:
sudo ufw allow 'Apache'
This command will allow traffic to come through on port 80. You can also enable HTTPS traffic on port 443 using the following command:
sudo ufw allow 'Apache Full'
Step 4: Test Apache Web Server
At this point, you have successfully installed Apache Web Server. To test if it’s working correctly, open your browser and navigate to your server’s IP address or domain name. You should see the default Apache2 Ubuntu Default Page.
Step 5: Configure Apache Web Server
Now that we’ve successfully installed Apache, we can begin to configure it to suit our needs. The Apache configuration files are located in the /etc/apache2/ directory. The two primary configuration files are apache2.conf and ports.conf.
You can modify the contents of these files using a text editor like nano or vim.
sudo nano /etc/apache2/apache2.conf
You can also use the a2enmod and a2dismod commands to enable or disable modules within Apache.
Step 6: Enable Virtual Hosting
If you want to host multiple websites on your server, you’ll need to enable virtual hosting. To do this, you’ll need to configure your server to respond to requests for multiple domain names or IP addresses. You can do this by creating a Virtual Host configuration file.
sudo nano /etc/apache2/sites-available/newdomain.com.conf
Once you’ve created the configuration file, you can enable it using the a2ensite command and restart Apache:
sudo a2ensite newdomain.com.conf
sudo systemctl restart apache2
Step 7: Install SSL Certificate
If you plan on running a secure website, you’ll need to install an SSL certificate on your server. You can do this using Let’s Encrypt, a free, automated, and open Certificate Authority.
Install Certbot:
sudo add-apt-repository ppa:certbot/certbot
sudo apt-get update
sudo apt-get install python-certbot-apache
Install Certbot Apache Plugin:
sudo apt-get install certbot python3-certbot-apache
Next, run the following command to obtain the SSL certificate:
sudo certbot --apache -d newdomain.com
Certbot will ask you a few questions and automatically configure your SSL settings.
