drop table innodb_index_stats;
drop table innodb_table_stats;
drop table slave_master_info;
drop table slave_relay_log_info;
drop table slave_worker_info;

FLUSH TABLES innodb_table_stats;

CREATE TABLE IF NOT EXISTS innodb_table_stats (
	database_name			VARCHAR(64) NOT NULL,
	table_name			VARCHAR(64) NOT NULL,
	last_update			TIMESTAMP NOT NULL NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,

展示:
innodb_index_stats.ibd   slave_master_info.ibd    slave_worker_info.ibd
innodb_table_stats.ibd   slave_relay_log_info.ibd

rm -f *.ibd
