It is generally accepted that host operating systems should include different filesystem partitions for different purposes. One set of filesystems is typically called system partitions, and these are generally reserved for host system/application operation.

Cómo se verifica

Método de auditoría: Revisión manual

Esta recomendación no se puede verificar automáticamente. Un escaneo la lista con estas instrucciones cuando se pasa --include-manual.

Find the data and log locations: SELECT VARIABLE_NAME, VARIABLE_VALUE FROM performance_schema.global_variables WHERE (VARIABLE_NAME LIKE '%dir' OR VARIABLE_NAME LIKE '%file') AND VARIABLE_NAME NOT LIKE '%core%'; then run df -h <directory> for datadir and the others. They must not be on the root (/), /var or /usr partitions.

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

Create a dedicated partition/volume for the data, stop MySQL, move datadir there (copy preserving ownership mysql:mysql), update datadir in /etc/my.cnf (or /etc/mysql/mysql.conf.d/mysqld.cnf) and any SELinux/AppArmor policy, then start MySQL.
