mysql>grant all on *.* to test@’192.168.1.20’ identified by ‘123456’
mysql>flush privileges;
结果显示：Grant_priv为"N"
解决方法：在最后加上With Grant Option
mysql>grant all on *.* to test@’192.168.1.20’ identified by ‘123456’ WITH GRANT OPTION
mysql>flush privileges;
结果显示：Grant_priv为"Y"
Mysql Grant权限(WITH GRANT OPTION)
