Mysql8.0 错误1227 Access Denied； you need the PROCESS(SYSTEM_USER) privilege(s) 问题解决

需要在root用户下，给 test 赋予 process 权限，语句如下

GRANT PROCESS ON *.* TO 'test'@'%';

可以根据提示 赋予权限

如提示 Access Denied; you need the SYSTEM_USER privilege(s)

可以使用语句赋予 SYSTEM_USER 权限

GRANT SYSTEM_USER ON *.* TO 'test'@'%';

也可赋予所有权限

GRANT ALL privileges on *.* to 'test'@'%' with GRANT option;

撤销用户所有权限

REVOKE ALL privileges ON *.* FROM 'test'@'%';
