How to install PHP 7.2.latest on Ubuntu 16.04
Advertisement:
I have a number of guides on moving away from CPanel, Setting up VM’s on UpCloud, AWS, Vultr or Digital Ocean along with installing and managing WordPress from the command line. PHP is my programming language of choice.
PHP has a support page that declares the support date ranges and support types: http://php.net/supported-versions.php
A version of PHP is either actively supported, security fix supported or end of life. Read this post to check WordPress for PHP compatibility.
From time to time vulnerabilities come up that require PHP updates to be applied.
Multiple flaw found in #PHP, most severe of which could allow arbitrary code execution
Affected Versions:
PHP 7.2 —prior to 7.2.5
PHP 7.1 —prior to 7.1.17
PHP 7.0 —prior to 7.0.30
PHP 5.0 —prior to 5.6.36https://t.co/TtiqXePoHuUpgrade to the latest version of PHP immediately

I have guides on setting up PHP 7 here on Digital Ocean, here on AWS and here on Vultr. I have tried upgrading to PHP 7.1 in the past with no luck (I forgot to change something and rolled back to 7.0).
FYI: I have a guide on setting up PHP child workers so the output from some commands below may be different than yours. Here are the steps I performed to install PHP 7.2 alongside 7.0 then switch. to 7.2.
Backup your system
Do perform a Snapshot or Backup before proceeding. Nothing beats a quick restore if things fail.
Note: Use this information at your own risk.
Updating php 7.2.12 to 7.2.12
Update your Ubuntu systems
1 | apt-get update && apt-get upgrade |
Updating from an older php (e.g 5.x, 7.1, 7.1 to say 7.2.12)
Backup PHP
1 2 | cd /etc/php zip -r php7.0backup.zip 7.0/ |
Install Helper
This software provides an abstraction of the used apt repositories. It allows you to easily manage your distribution and independent software vendor software sources. More Info
1 | apt-get install python-software-properties |
Add the main PHP repo (more information)
1 | add-apt-repository ppa:ondrej/php |
Update the package lists
“In a nutshell, apt-get update doesn’t actually install new versions of the software. Instead, it updates the package lists for upgrades for packages that need upgrading, as well as new packages that have just come to the repositories.” from here
1 | apt-get update |
Verify New Packages
1 | dpkg -l |
Install PHP 7.2
1 | apt-get install php7.2 |
Install common PHP modules
1 | apt-get install php-pear php7.2-curl php7.2-dev php7.2-mbstring php7.2-zip php7.2-mysql php7.2-xml |
Install PHP FPM
1 | apt-get install php7.2-fpm |
Update all packages (may be needed to update from php 7.2.4 to 7.2.5)
1 | sudo apt-get upgrade |
Edit your NGINX sites-available config
1 2 | sudo nano /etc/nginx/sites-available/default # I set: fastcgi_pass /run/php/php7.2-fpm.sock; |
Edit your NGINX sites-enabled config
1 2 | sudo nano /etc/nginx/sites-enabled/default # I set: fastcgi_pass unix:/var/run/php/php7.2-fpm.sock; |
I edited these lines
1 2 3 4 5 | location ~ \.php$ { ... fastcgi_pass unix:/var/run/php/php7.2-fpm.sock; ... } |
Edit your PHP config (and make desired changes)
1 | sudo nano /etc/php/7.2/fpm/php.ini |
Edit your PHP pool config file (as required). See this guide here.
1 | sudo nano /etc/php/7.2/fpm/pool.d/www.conf |
Make sure you set: listen = /run/php/php7.2-fpm.sock
Set PHP 7.2 as the default PHP
1 | update-alternatives --set php /usr/bin/php7.2 |
Check your PHP version
1 | php -v |
Reload PHP
1 | sudo service php7.2-fpm reload |
Reload NGINX
1 2 3 | nginx -t nginx -s reload /etc/init.d/nginx restart |
Check the status of your PHP (and child workers)
