Points To Remember

Nginx is pronounced as Engine-x
It is open source
It is a High performance HTTP server and Reverse proxy
It does not rely on thread to handle requests. Thus it can serve thousands of concurrent requests.
It works on scalable event driven (asynchronous) architecture.

Getting started with NGINX

Install nginx
```
sudo apt-get install nginx
```
Check the status of the server
```
sudo service nginx status
```
Start the nginx server
```
sudo service nginx start 
```

Go to the browser and enter the url http://localhost you will see the following screen.

Our nginx server is up and running.

Viewing the NGINX configuration files.

You can go to the folder /etc/nginx to view the Nginx configuration files.

The image above shows how the nginx files looks like.

For getting started the important files you should be familiar to are

mime.types it includes all the mime types the the ngnix server will support.
nginx.conf it contains most of the configuration that is required for a normal application. It contains the following things

events block - it contains the number of connections to support
http block - it contains the server settings, logging settings and other basic settings.
mail block - for pop/imap services

sites-available - This is where you define your server configurations for different sites/applications.
sites-enabled- it contains the soft link to the sites/applications that are defined in sites-available.

How to Configure Nginx to serve a new Site

Go to /etc/hosts create a new entry there e.g site1.ekiras.com 127.0.0.1

Create a new server configuration in sites-available folder e.g

site1.ekiras.com

server{
 listen   80;
 server_name site1.ekiras.com;
 root  /home/ekansh/;
 index index.html;
 
 location / {
 } 
}

Enable this site by adding a soft link to this file

sudo ln -s /etc/nginx/sites-available/site1.ekiras.com site1.ekiras.com

Now restart the nginx server using command
```
sudo service nginx restart
```

Go to the browser and open the url http://site1.ekiras.com you will be able to see the html page on the home directory by name index.html
