Replace the code below and nginx_testing.com with your domain.
 

server {
    listen   80; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default ipv6only=on; ## listen for ipv6
    index index.php index.html index.htm;
    # Make site accessible from http://localhost/
    server_name nginx_testing.com;
    # You can specify another sub domain aswell.
    # server_name www.nginx_testing.com;
    root /var/www/nginx_testing;
#   access_log "/var/logs/nginx_access_log";
#   error_log "/var/logs/nginx_error_log";
    # enforce www (exclude certain subdomains)
#   if ($host !~* ^(www|subdomain))
#   {
#       rewrite ^/(.*)$ $scheme://www.$host/$1 permanent;
#   }
    # enforce NO www
#   if ($host ~* ^www\.(.*))
#   {
#       set $host_without_www $1;
#       rewrite ^/(.*)$ $scheme://$host_without_www/$1 permanent;
#   }
    # set the expiry of following extensions
    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$
    {
        #expires max;
        expires 1y;
        log_not_found off;
        add_header Pragma public;
        add_header Cache-Control "public, must-revalidate, proxy-revalidate";
    }
    location ~ ^/(.*\.(ac3|avi|bmp|bz2|css|cue|dat|doc|docx|dts|exe|flv|gif|gz|htm|html|ico|img|iso|jpeg|jpg|js|mkv|mp3|mp4|mpeg|mpg|ogg|pdf|png|ppt|pptx|qt|rar|rm|swf|tar|tgz|txt|wav|xls|xlsx|zip|ttf|eot|svg|woff))$ {
        try_files $uri @fallback;
    }
    # This block will disbale .htacess
    location ~ /\.ht {
        deny all;
    }
    location / {
        try_files $uri $uri/ /index.php?u=$request_uri;
    }
    location ~ \.php$
    {
        fastcgi_pass unix:/run/php5-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /var/www/nginx_testing$fastcgi_script_name;
        include fastcgi_params;
    }
    # Always place these at the bottom of "server" block.
    error_page 404 /error_404.html;
    error_page 500 502 503 504 /error_5xx.html;
    location = /error_5xx.html {
        root  /var/www/nginx_testing;
    }
}

sudo ln -s /etc/nginx/sites-available/nginx_testing.com /etc/nginx/sites-enabled/nginx_testing.com

Restart the server to see the changes
