Getting Started with Nginx

Welcome to the tutorial on getting started with Nginx! Nginx is a high-performance web server that is known for its stability, security, and efficiency. In this guide, we will cover the basics of installing, configuring, and using Nginx.

Prerequisites

Before you begin, make sure you have the following prerequisites:

• A Linux server (Ubuntu, CentOS, etc.)
• Root access to the server
• Basic knowledge of Linux commands

Installation

To install Nginx, you can use the package manager of your Linux distribution. Here's how you can do it on Ubuntu:

sudo apt update
sudo apt install nginx

On CentOS, you can use:

sudo yum install nginx

After the installation is complete, you can check if Nginx is running with:

sudo systemctl status nginx

Basic Configuration

Nginx uses a configuration file located at /etc/nginx/nginx.conf. You can edit this file to customize the behavior of your web server.

Here's a basic configuration example:

user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;

        location / {
            root   /usr/share/nginx/html;
            index  index.html index.htm;
        }
    }
}

Testing the Configuration

After making changes to the configuration file, you need to test it to ensure there are no syntax errors. You can do this with the following command:

sudo nginx -t

If the test is successful, you can reload Nginx to apply the changes:

sudo systemctl reload nginx

Accessing Your Website

Now that Nginx is installed and configured, you can access your website by navigating to http://localhost in your web browser.
