How to Install Nginx on Ubuntu 15.04.

Introduction

Nginx is a free, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server. Nginx is written to address the C10K problem. Unlike traditional servers such as Apache, Nginx doesn't rely on threads to handle requests. Instead, it uses an event-driven (asynchronous) architecture.

In this tutorial, we will install Nginx on your Ubuntu 15.04 server.

Nginx can be easily installed on Ubuntu using apt-get package repository. Use the following commands to install Nginx on your server.

# sudo apt-get update
# sudo apt-get install nginx
