I have had an older SuiteCRM installed and dropped everything to start fresh with 7.11.6.
Environment: PHP 7.2,20 (also tried 7.3), MySQL 5.7.26, CentOS 7
Installation begins, existing mysql database (via cPanel) and then reports:
Creating SuiteCRM configuration file (config.php)
Creating SuiteCRM application tables, audit tables and relationship metadata
Creating the database crmdb_current on localhost…done
…Database error. Please check suitecrm.log for details.
The log shows
