Mysql普通用户不用输入密码也登陆解决办法

我给user设置了密码但是也可以不用-p直接访问数据库，郁闷。

下面进入root用户通过代码查询它的密码 返回的是

+-----------+------+-------------------------------------------+-------------+-------------+

| Host | User | Password | Select_priv | Insert_priv | ...

+-----------+------+-------------------------------------------+-------------+-------------+

| localhost | root | *FD571203974BA9AFE270FE62151AE967ECA5E0AA

| % | lynn | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9

| +-----------+------+-------------------------------------------+-------------+-------------+

使用select password('123456');

验证结果

+-------------------------------------------+

| password('123456') |

+-------------------------------------------+

| *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9

|+-------------------------------------------+

1 row in set (0.00 sec)看来我设置的是正确的。但是进入的时候居然不要密码...

!!解决思路:是不是因为lynn用户没有设置登入域(localhost)导致?

--返回Query OK, 0 rows affected (0.00 sec)

退出root 重新试试

C:\Documents and Settings\Administrator>mysql -ulynn -hlocalhost

ERROR 1045 (28000): Access denied for user 'lynn'@'localhost' (using password: NO)

!!果然 添加到Host才要求输入密码。
