Upgrade PHP from 7.2 to 7.4 on CentOS 8 and Apache

This was super helpful to upgrade a CENTOS 8 machine from PHP 7.2 to 7.4. I turned it into a quick script to automate it and to make sure you install all of the PHP 7.2 modules you had previously.

Enjoy

#!/usr/bin/bash
#This script upgrades CENTOS 8 from PHP 7.2 to 7.4
#-----------------------------------------

if [ `whoami` != "root" ];
then
echo "Sorry, gotta be root!"
exit 0
fi

echo "This script will upgrade PHP 7.2 to 7.4 on Centos 8"
echo ""
echo "Press CTRL-C to stop, or any key to continue"

if [[ `cat /etc/centos-release | grep 'CentOS Linux release 8.'` ]];
then
echo "You are on Centos 8, proceeding."
else
echo "Not on Centos 8. Sorry, exiting."
exit 1
fi

echo "These are your current PHP modules installed. Saving to /tmp/php-7.2.modules.txt"
echo ""
rpm -qa | grep php | tee -a /tmp/php-7.2.modules.txt
echo ""

pkgs=`rpm -qa --queryformat "[%{NAME}\n]" | grep php | sort`

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
dnf module list php
dnf module reset php
dnf module enable php:remi-7.4

dnf install $pkgs

echo "Upgrade complete."
