Ensure the `daemon_memcached` Plugin Is Disabled

中等級 1自動化tdsql

說明

The daemon_memcached plugin allows direct access to InnoDB tables via the Memcached protocol, bypassing SQL-layer privilege checks. Runs the mysql client against the TDSQL data node selected by TDSQL_MYSQL_OPTS (e.g. "-h10.0.0.5 -P4001 -utdsql_audit"); keep the password in ~/.my.cnf or a login path rather than MYSQL_PWD or the command line (see 1.4 and 1.5).
