 +  * yum reinstall <mysql_package> that was failing
 +  * postfix started
 +  * Other trouble...had to completely uninstall PHP

 +  * Then upgrade to REMI php v7.4
 +  * Restore /etc/php.ini from a local VM
 +  * yum update had many instances of 'empty files'....it fixed itself

 +    * yum reinstall oniguruma5
 +    * yum reinstall oniguruma
