NGINX UBUNTU UBUNTU 16.04
Introduction

Nginx is one of the most popular web servers in the world and is responsible for hosting some of the largest and highest-traffic sites on the internet. It is more resource-friendly than Apache in most cases and can be used as a web server or a reverse proxy.

In this guide, we'll discuss how to get Nginx installed on your Ubuntu 16.04 server.

Prerequisites
Before you begin this guide, you should have a regular, non-root user with sudo privileges configured on your server. You can learn how to configure a regular user account by following our initial server setup guide for Ubuntu 16.04.

-uuser_name -ppassword 
-u user_name -ppassword

sudo apt update
sudo apt install phpmyadmin

This is a : no need to think setup for Ubuntu 16.04 with php7-fpm already installed.

Then copy paste just before the last } of the file the following block into /etc/nginx/sites-avaliable/default

location /phpmyadmin {
    root /usr/share/;
    index index.php index.html index.htm;
