MySQL添加新用户,为新用户分配权限，Mysql版本5.7（Server version: 5.7.22 MySQL）

首先进入Mysql控制台：

mysql -uroot -p

创建一个新用户(user)并为此用户分配权限（这里先分配对所有数据库的表增删改查的权限），identified by 后面填入你新用户的密码

grant select,insert,update,delete on *.* to 'user'@'%' identified by 'your password';

如果是给予全部权限那么就这样

grant all privileges on *.* to 'user'@'%' identified by 'your password';

记得每次操作完要刷新授权

flush privileges;

grant 后面跟着就是具体操作权限，权限列表参考MySQL官网说明 Privileges Provided by MySQL
