Step 1 – Install PHP

PHP 7 is the default available packages in Ubuntu 16.04 repositories. Simply use the following commands to update apt cache and install PHP packages on your system.

$ sudo apt update
$ sudo apt install php php-fpm

Verify installed PHP version using following command.

rahul@tecadmin:~$ php -v

PHP 7.0.4-7ubuntu2 (cli) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies

Step 2 – Install NGINX

First we will install Nginx web server on our system. Use the following commands to install Nginx web server on your Ubuntu 16.04 LTS server.

$ sudo apt install nginx

Step 3 – Install MySQL

Finally install mysql-server packages for MySQL database. Also install php-mysql package to use MySQL support using php. Use following command to install it.

$ sudo apt install mysql-server php-mysql

Installer will prompt for root password, This password will work for your MySQL root user. After installing MySQL execute following command for initial settings of MySQL server. You will she that script will prompt about more settings than earlier mysql versions like password validation policy etc.

$ sudo mysql_secure_installation

Step 4 — Configure PHP-FPM

PHP-FPM (FastCGI Process Manager) is an alternative PHP FastCGI implementation with some additional features.

$ sudo nano /etc/php/7.0/fpm/php.ini

un-comment cgi.fix_pathinfo=1 line and set value to 0.

cgi.fix_pathinfo=0

Now set the listen parameter in /etc/php/7.0/fpm/pool.d/www.conf configuration file. Here you can use php5-fpm socket to work or start php5-fpm server on any port as service. We are going to use it as service.

$ sudo nano /etc/php/7.0/fpm/pool.d/www.conf

Now make changes in configuration file as below. Commend listen with socket file and enable it as service

; listen = /run/php/php7.0-fpm.sock
listen = 127.0.0.1:9000

Step 5 — Configure Nginx VirtualHost

Finally do the configuration of Nginx virtualhost. For this example we are editing default configuration file.

$ sudo nano /etc/nginx/sites-enabled/default.conf

and make changes as below.

server {
        listen   80;

        root /var/www;
        index index.php index.html index.htm;
        server_name  example.com www.example.com;

        location / {
                try_files $uri $uri/ /index.html;
        }

        error_page 404 /404.html;
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
              root /usr/share/nginx/www;
        }

        location ~ .php$ {
                try_files $uri =404;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
}

You have to do the same changes in all VirtualHosts configured.

Step 6 – Restart Services

After installing all services on your system, start all required services.

$ sudo systemctl restart nginx.service
$ sudo systemctl restart php7.0-fpm.service

Step 7 – Open Access in Firewall

If you are using iptables, Use following commands to open port 80 for public access of webserver.

Iptables Users:

$ sudo iptables -A INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT

UFW Users:

$ sudo ufw allow 80/tcp

Step 8 – Test Setup

After completing all setup. Let’s create a info.php file website document root with following content.

<?php
 phpinfo();
?>

Now access this file in web browser. You will see the screen like below with all details of PHP on server.

Congratulation’s! You have successfully configured LEMP Stack on your Ubuntu 16.04 LTS server.
