apt-get install apache2 mysql-server -y

After installing both packages, run the following command to install PHP with all required extensions:

apt-get install php7.4 libapache2-mod-php7.4 php7.4-common php7.4-mysql php7.4-gmp php7.4-curl php7.4-intl php7.4-mbstring php7.4-xmlrpc php7.4-gd php7.4-bcmath php7.4-xml php7.4-cli php7.4-gmagick php7.4-zip curl unzip git -y

chmod -R 755 /var/www/html/neoscms/

Configure Apache for Neos CMS

            RewriteBase /
            RewriteCond %{REQUEST_FILENAME} !-f
