mysql仅显示database（）信息_模式数据库

Question

I use mysql -u root -p to login to mysql. Command show databases only shows information_schema database, and current_user is not root

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
+--------------------+
2 rows in set (0.00 sec)

mysql> select current_user();
+----------------+
| current_user() |
+----------------+
| @localhost     |
+----------------+
1 row in set (0.00 sec)

Answer 1

You have no other databases - try to create one.

The current user is probably the anonymous user - by default MySQL ships with the following users, all having empty password ( https://dev.mysql.com/doc/refman/5.5/en/default-privileges.html )
