Loaded: loaded (/lib/systemd/system/php7.2-fpm.service; enabled; vendor preset: enabled)
Active: active (running) since Sat 2018-06-30 23:56:14 PDT; 1min 28s ago
Docs: man:php-fpm7.2(8)
Main PID: 10080 (php-fpm7.2)
Status: "Processes active: 0, idle: 2, Requests: 0, slow: 0, Traffic: 0req/sec"
Tasks: 3 (limit: 2321)
CGroup: /system.slice/php7.2-fpm.service
|-10080 php-fpm: master process (/etc/php/7.2/fpm/php-fpm.conf)
You would now be able to alter the Nginx worker square and add the accompanying lines so Nginx can deal with PHP records:
server {
# . . . other code
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/run/php/php7.2-fpm.sock;
}
}
Remember to restart the Nginx administration so the new arrangement produce results:
sudo systemctl restart nginx

sudo apt install php-[extname]
For instance in the event that you need to introduce MySQL and GD PHP augmentations you would run the accompanying order:

/var/www/html/info.php
<?php
phpinfo();
Save the document, open your program of decision and visit http://your_server_ip/info.php
