mysql5.7创建用户 分配权限

创建用户（%表示随处可登录，localhost表示只能本地登录

create user 'username'@'%' identified by 'password';

分配权限

grant all privileges on tableName.* to 'username'@'%';

刷新权限

flush privileges;

如果报错ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

先执行flush privileges;再进行操作
