Introduction
Welcome to our guide on configuring Apache on Ubuntu Server! Apache, a widely used web server, can be installed on Ubuntu Server to serve web pages and other content. This configuration process can be daunting for beginners, but with our step-by-step guide, we’ll make it easier for you to understand and configure Apache on your Ubuntu Server.
Ubuntu is a popular operating system that is widely used in servers. It’s known for its ease of use, security, and stability. Meanwhile, Apache is one of the most popular web servers in the world, powering millions of websites.
Before we dive into the configuration process, let’s discuss the basics of Apache and Ubuntu, which will help you better understand the configuration process down the line.
The Basics of Apache
Apache is an open-source web server software that can handle both static and dynamic content, and it’s cross-platform, meaning it can run on different operating systems like Linux, Windows, and macOS. Apache can be used for different purposes like web hosting, files sharing, and more. Apache is also known for its flexibility and security. It can handle multiple requests at a time, thus providing high performance.
Apache is modular, which means you can add or remove functionalities as needed. Modules are separate pieces of code that can be installed, activated, or deactivated. There are a lot of modules available for Apache, including those for PHP and SSL.
The Basics of Ubuntu Server
Ubuntu Server is a free and open-source operating system that’s known for its ease of use, flexibility, and security. It’s based on Debian, another popular Linux distribution. Ubuntu Server can be used for different purposes like web hosting, cloud computing, file sharing, and more. It’s designed to be lightweight, which means it can run on older hardware as well.
Ubuntu Server comes with a lot of pre-installed software, including Apache, but you can also install and configure other software as needed. Ubuntu Server uses a package manager called apt, which makes it easy to install and update software on your server.
Prerequisites
Before we start configuring Apache on Ubuntu Server, you need to make sure you have the following:
Item |
Minimum Requirement |
|---|---|
Ubuntu Server |
Version 16.04 or later |
SSH Access |
You need to be able to access your Ubuntu Server via SSH |
Superuser Privileges |
You need to have superuser privileges to install and configure Apache |
Configuring Apache on Ubuntu Server
Now that we’ve covered the basics, let’s dive into the configuration process of Apache on Ubuntu Server. The process consists of the following:
- Installing Apache
- Configuring Firewall
- Configuring Virtual Hosts
- Enabling Modules
- Securing Apache
- Creating a Test Page
- Restarting Apache
Installing Apache
The first step is to install Apache on your Ubuntu Server. You can do this by running the following command:
sudo apt-get install apache2
This command will install Apache and its dependencies. Once the installation is complete, you can verify it by running:
sudo systemctl status apache2
If everything went well, you should see a message that says “Active: active (running)”.
Configuring Firewall
Next, you need to configure the firewall to allow HTTP and HTTPS traffic. You can do this by running the following commands:
sudo ufw allow 'Apache'
sudo ufw allow 'Apache Full'
The first command allows HTTP traffic, while the second command allows HTTPS traffic. You can verify the status of the firewall by running:
sudo ufw status
Configuring Virtual Hosts
Virtual Hosts are used to host multiple websites on a single server. You can configure Virtual Hosts by creating a new file in the /etc/apache2/sites-available/ directory. You can name this file whatever you want, but it should end with “.conf”.
Open this file with your favorite text editor, and add the following code:
<VirtualHost *:80>ServerAdmin webmaster@localhostDocumentRoot /var/www/html/example.com/public_htmlServerName example.comErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>
This code sets up a Virtual Host for a website called “example.com”. You can change the name, document root, and other settings as needed. Once you save this file, you need to enable the Virtual Host by running:
sudo a2ensite conf_file_name
Replace “conf_file_name” with the name of your configuration file. Finally, you need to restart Apache by running:
sudo systemctl restart apache2
Your Virtual Host is now ready to use.
Enabling Modules
Apache comes with a lot of modules that you can enable or disable as needed. Some of the commonly used modules are:
- mod_ssl: used for enabling SSL on Apache
- mod_rewrite: used for URL rewriting
- mod_php: used for running PHP scripts on Apache
You can enable a module by running:
sudo a2enmod module_name
Replace “module_name” with the name of the module. You can disable a module by running:
sudo a2dismod module_name
Restart Apache after enabling or disabling a module by running:
sudo systemctl restart apache2
Securing Apache
Apache can be secured by disabling directory listing, enabling HTTPS, and more. To disable directory listing, you can add the following code to your Virtual Host configuration file:
<Directory /var/www/html>Options -Indexes</Directory>
This will prevent Apache from displaying a list of files in a directory if there is no index file present.
To enable HTTPS, you need to install an SSL certificate on your server. You can get a free SSL certificate from Let’s Encrypt, or you can purchase one from a certificate authority. Once you have the certificate, you can enable HTTPS by adding the following code to your Virtual Host configuration file:
<VirtualHost *:443>ServerAdmin webmaster@localhostDocumentRoot /var/www/html/example.com/public_htmlServerName example.comSSLEngine onSSLCertificateFile /path/to/certificate_fileSSLCertificateKeyFile /path/to/certificate_key_fileSSLCertificateChainFile /path/to/certificate_chain_fileErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>
This code sets up a Virtual Host for HTTPS. Replace the path to the certificate files with the actual path on your server.
Creating a Test Page
You can create a simple test page to verify that Apache is working correctly. Create a new file in the /var/www/html/ directory called “index.html”. Add the following HTML code:
<!DOCTYPE html><html><head><title>Test Page</title></head><body><h1>Test Page</h1><p>This is a test page</p></body></html>
Save this file and open your web browser. Navigate to “http://your_ip_address/”. You should see the Test Page.
Restarting Apache
If you make any changes to Apache’s configuration files, you need to restart Apache for the changes to take effect. You can do this by running:
sudo systemctl restart apache2
