35. Installing WordPress: PHP 7.4
We start with the installation of PHP 7.4 from Remi's repo. PHP 7.4 fully supports all
authentication plugins of MySQL 8.0:
sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
sudo yum-con g-manager --enable remi-php74
sudo yum install php php-cli php-mysqlnd php-zip php-gd
php-mcrypt php-mbstring php-xml php-json
