=== Basic HTTP-only nginx server_block ===
\\
First we need to edit **/etc/nginx/nginx.conf** to allow virtual hosts (known as server blocks when using nginx)
This guide will show how to configure server blocks in the same manner as Ubuntu apache vhosts, using sites-available and sites-enabled.
\\
Add the following line to the configuration in the http section:

<sxh bash>
include /etc/nginx/sites-enabled/*;
</sxh>
\\
Now the best practice for nginx is to create a system similar to that of vhosts using ubuntu. Create the following directories to configure the vhosts:
<sxh bash>
mkdir /etc/nginx/sites-available
</sxh>
<sxh bash>
mkdir /etc/nginx/sites-enabled
</sxh>
\\
Once these have been made, go to **/etc/nginx/sites-available** and create a vhost with the following configuration:
<sxh bash>
server {
    listen 80;
    server_name lukeshirnia.co.uk www.lukeshirnia.co.uk;
    access_log /var/log/nginx/lukeshirnia.co.uk.access.log;
    error_log /var/log/nginx/lukeshirnia.co.uk.error.log;
    root /var/www/html/lukeshirnia.co.uk;

location / {
    index index.html index.htm index.php;
    try_files $uri $uri/ =404;
}

location ~ \.php$ {
    include /etc/nginx/fastcgi_params;
    fastcgi_pass  127.0.0.1:9000; #this means php-fpm will run on a port
    # fastcgi_pass unix:/run/php-fpm/example.com.sock; or you could have php-fpm running on a socket
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME /var/www/html/lukeshirnia.co.uk$fastcgi_script_name;
    }
}
</sxh>
\\
You can see that php will be handled by PHP-FPM listening on port 9000. This port does not need to be opened. If you type: netstat -plnt you will be able to see PHP-FPM listening to the port.

Once the vhost had been created we will need to create a symbolic link from **/sites-available/** to **/sites-enabled/**.

Moving into the **/etc/nginx/sites-enabled/** directory and type the following:

<sxh bash>
ln -s /etc/nginx/sites-available/lukeshirnia.co.uk
</sxh>

Your vhost should now work.

If you wish to take a site offline for any reason, you can remove the symbolic link by using the 'rm' command on the vhost in **/etc/nginx/sites-enabled/**

And you are DONE!

**Restart PHP-FPM** and nginx if you face any issues.
