When venturing into the realm of website management, some users find shared hosting adequate, while others opt for the control of a Virtual Private Server (VPS). This guide will not only walk you through setting up a secure web server using Apache on Ubuntu 16.04 but also provides insights on hardening your Ubuntu server for enhanced security. Let’s dive into the details.

Setting Up a Secure Web Server on Ubuntu 16.04:  Installing Apache

Begin by logging into your VPS using SSH, a crucial step for server management. Update sources and existing packages with the commands:

apt-get update && apt-get upgrade

Install Apache with:

apt-get install apache2

Now you have a functional web server on your VPS.

Configuring Let’s Encrypt

With Apache running, securing your website with an SSL certificate becomes paramount. Install Git using:

apt-get install git

Clone Let’s Encrypt repository and navigate to it:

git clone https://github.com/letsencrypt/letsencrypt && cd letsencrypt

Execute the command to obtain a free SSL certificate:

./letsencrypt-auto --apache --renew-by-default -d domain.com -d www.domain.com

Replace “domain.com” with your actual domain. Follow the prompts to complete the setup.

Enabling .htaccess Files

To use .htaccess files, edit the Apache configuration file:

cd && cd /etc/apache2 && nano apache2.conf

Change the relevant “AllowOverride” lines to:

cd && cd /etc/apache2 && nano apache2.conf

Save the changes, then enable Apache mod_rewrite and restart Apache:

a2enmod rewrite && apachectl restart

Create your .htaccess file in the web server’s root directory:

cd && cd /var/www/html && nano .htaccess

Harden Ubuntu Server 16.04: Strengthening Server Security

Updating System

Keeping your server’s software up-to-date is crucial. Schedule regular updates using:

apt-get update && apt-get upgrade

Configuring Firewall

Enhance security by configuring the firewall. Use Uncomplicated Firewall (UFW) for simplicity:

apt-get install ufw
ufw allow ssh
ufw enable

Conclusion

With the diligent application of these security measures, you not only fortify your Ubuntu Server 16.04 but also gain the confidence to navigate the intricate landscape of web infrastructure security. Stay vigilant, stay secure!
