This enables IP addresses to be resolved back to hostnames, complementing the forward lookup zone created in previous labs.</p> <p>By the end of this lab, the DNS server will support both:</p> <ul> <li>Forward lookups (hostname → IP address)</li> <li>Reverse lookups (IP address → hostname)</li> </ul> <hr> <h2 id="environment">Environment</h2> <ul> <li>Virtualization: VirtualBox</li> <li>OS: ( 1 DNS Server VM + 1 Web Server VM + 1 Client VM)</li> </ul> <hr> <h2 id="network-topology">Network Topology</h2> <p><img alt="dns-topology" loading="lazy" src="https://my-it-blog.netlify.app/posts/reverse-dns/dns-topology.png"></p> https://my-it-blog.netlify.app/posts/nginx-virtual-hosts/ Fri, 03 Jul 2026 00:00:00 +0000 https://my-it-blog.netlify.app/posts/nginx-virtual-hosts/ <h1 id="hosting-multiple-websites-on-one-server-using-nginx">Hosting Multiple Websites on One Server Using Nginx</h1> <h2 id="objective">Objective</h2> <p>Host multiple websites on a single web server by combining:</p> <p>DNS (BIND9) Nginx Virtual Hosts (Server Blocks)</p> <hr> <h2 id="environment">Environment</h2> <ul> <li>Virtualization: VirtualBox</li> <li>OS: ( 1 DNS Server VM + 1 Web Server VM + 1 Client VM)</li> </ul> <hr> <h2 id="network-topology">Network Topology</h2> <p><img alt="dns-topology" loading="lazy" src="https://my-it-blog.netlify.app/posts/nginx-virtual-hosts/dns_vhost_topology.png"></p> <hr> <h2 id="prerequisites">Prerequisites</h2> <p>This lab builds upon the Private DNS Infrastructure with BIND9 (3-VM Lab). The following components are assumed to already be configured:</p> <ul> <li>BIND9 installed and running on the DNS server.</li> <li>The company.lab DNS zone created and configured.</li> <li>The zone file (/etc/bind/db.company.lab) already exists.</li> <li>The client is configured to use the internal DNS server (192.168.10.10) via Netplan.</li> <li>DNS resolution between the client and the DNS server has been verified.</li> </ul> <p>In this lab, the existing DNS infrastructure is extended by adding additional DNS records and configuring Nginx virtual hosts to host multiple websites on a single web server.</p>
