Question

我创建了一个新用户，但无法授予访问权限。但是我可以使用新用户“ apple.2”登录到mysql，但无法授予它访问权限或创建数据库。我还有一个叫“苹果”的用户，但我不认为这是问题所在。

~$ mysql -u apple.2 -p
Enter password:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.2_class' at line 1

mysql> grant all privileges on *.* to 'apple.2' identified by 'password';
ERROR 1045 (28000): Access denied for user 'apple.2'@'%' (using password: YES)

Answer 1

除非引用，否则数据库名称中没有.。

create database `apple.2_class`;

数据库名称与用户名不同。您需要使用更高的priv用户（通常为root）才能将priv授予apple.2

开始创建用户，然后授予用户许可的实践。合并后的版本在MySQL-8.0中已经消失。

create user 'apple.2' identified by 'password';
grant all privileges on *.* to 'apple.2';

错误1064（42000）：错误1064（42000）：您的SQL语法有错误；
