The redis extension for our case needs to be installed as well. There is a case where amazon-linux-extras might not include redis into their packages and for that reason we need to go with a third party repository like remi.
Code Block sudo yum install https://rpms.remirepo.net/enterprise/remi-release-7.rpm sudo yum-config-manager --enable remi-php81 sudo yum install php-redis
After installing redis it’s a good idea to go back to amazon-linux-extras repository.
Code Block sudo amazon-linux-extras enable php8.1 yum clean metadata
After installing all the php packages it is mandatory to change the max_input_vars to 5000. This can be found in /etc/php.ini
