I messed the VPS server configuration up while trying to upgrade from PHP 7.1 to 7.2 and i need this to be urgently fixed, the server is hosted with Vultr and running CentOS 6. It's a Wordpress site, so please let me know if you can help as soon as possible.
Someone the issue i get is:
Mysqld service keeps shutting down itself.
On wp-admin page, i get WP Rocket cannot configure itself due to missing writing permissions.
And maybe other problems that i haven't spotted yet
