Ensure 'super_priv' is Not Set to 'Y' for Replication Users

TinggiLevel 1Otomatismariadb

Deskripsi

The SUPER privilege found in the mysql.user table governs the use of a variety of MariaDB features. These features include, CHANGE MASTER TO, KILL, mysqladmin kill option, PURGE BINARY LOGS, SET GLOBAL, mysqladmin debug option, logging control, and more. Treats every account other than root and mysql (the MariaDB system administrator accounts) holding REPLICATION SLAVE as a replication user and counts those that also hold SUPER. Runs mariadb -NBe with the client defaults: as root on the server the unix_socket plugin usually authenticates; otherwise put an administrative account in ~/.my.cnf (mode 0600), not MYSQL_PWD (see 1.4/1.6).
