event_scheduler是off

sql查询是否打开状态：SHOW VARIABLES LIKE 'event_scheduler'

用脚本来打开：

mysql -u root -p

mysql event_scheduler
开启event_scheduler sql指令：
SET GLOBAL event_scheduler = ON;
SET @@global.event_scheduler = ON;
SET GLOBAL event_scheduler = 1;
SET @@global.event_scheduler = 1;
相反，关闭event_scheduler指令：
 
SET GLOBAL event_scheduler = OFF;
SET @@global.event_scheduler = OFF;
SET GLOBAL event_scheduler = 0;
SET @@global.event_scheduler = 0;
