Install PHP7.2 NGINX and PHP7.2-FPM on Ubuntu 16.04
########## Install NGINX ##############
# Install software-properties-common package to give us add-apt-repository package
sudo apt-get install -y software-properties-common
# Install latest nginx version from community maintained ppa
sudo add-apt-repository ppa:nginx/stable
# Update packages after adding ppa
sudo apt-get update
# Install nginx
sudo apt-get install -y nginx
# Check status
sudo service nginx status
# Start nginx if it is not already running
sudo service nginx start
# At this point you should have NGINX up and running, open http://localhost on your
# browser and you should see a welcome page from NGINX

# Once done all basic modules will be installed now, lets check the version now
php -v
# PHP 7.2.2-3+ubuntu16.04.1+deb.sury.org+1 (cli) (built: Feb 6 2018 16:11:23) ( NTS )
# Copyright (c) 1997-2018 The PHP Group

# Lets also check if the PHP7.2-FPM is running, if not start it
sudo service php7.2-fpm status
sudo service php7.2-fpm start # (if the service isn't running already)
# Now we need to configure the Gateway so that PHP-FPM uses the UNIX socket for executing PHP files.
# For this we need to check where is the PHP7.2-fpm service running from and where are their configurations stored
sudo ps aux | grep php # (this will list php process)
# You will see the output something like below depending on how many processes are running
# root 13122 0.0 0.0 412040 14752 ? Ss 12:17 0:00 php-fpm: master process (/etc/php/7.2/fpm/php-fpm.conf)
# www-data 13123 0.0 0.0 412040 8424 ? S 12:17 0:00 php-fpm: pool www
# www-data 13124 0.0 0.0 412040 8424 ? S 12:17 0:00 php-fpm: pool www
# root 13126 0.0 0.0 11288 868 pts/1 S+ 12:17 0:00 grep --color=auto php
# You will see the php-fpm master process is its location as /etc/php/7.2/fpm/php-fpm.conf. We now need to check the socket details
# from the PHP7.2-fpm by view this file.
vim /etc/php/7.2/fpm/php-fpm.conf
# You will see at the end of the file something like 'include=/etc/php/7.2/fpm/pool.d/*.conf' which means this process manager is using configurations from
# the pool.d directory. When viewing the /etc/php/7.2/fpm/pool.d/www.conf you will see that the PHP7.2-fpm (process manager) is
# listening to the socket at 'listen = /run/php/php7.2-fpm.sock'
# Copy the socket location i.e. /run/php/php7.2-fpm.sock and we will use this socket to tell nginx to use this socket
vim /etc/nginx/site-available/default
# You will need to tell NGINX to process the index.php files as well so replace the following line
# index index.html index.htm index.nginx-debian.html;
# to
# index index.html index.htm index.php;
# Also you will see something like the following block for 'location'
#location ~ \.php$ {
# include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
# fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
#}
# Make changes so to the above block so you have the following one:
location ~ \.php$ {
include snippets/fastcgi-php.conf;
#
# # With php-fpm (or other unix sockets):
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
# # With php-cgi (or other tcp sockets):
# fastcgi_pass 127.0.0.1:9000;
}
# Note we have uncommented the location, and fastcgi_pass lines and also pasted the correct socket that
# is used by our php7.2-fpm (process manager)
# lets now restart both nginx and php7.2-fpm
sudo service nginx reload
sudo service php7.2-fpm restart
# Now lets create a index.php file within the document root i.e. root /var/www/html;
touch /var/www/html/index.php
# and put phpinfo() and save it.
# now open http://localhost and you should see the screen with all php informaiton
