解决mysql

在按照前面文章中方法搭建Mysql数据库之后，发现其他机器还是不能访问，

参考以下文章对权限进行修改之后，发现本地机器中root不能访问了。

后来使用 select host, user, grant_priv from user;

发现grant_priv一列有问题，只有有grant_priv的用户才能对其他用户赋予权限。

修改成以下这样，就好了。

+-------------------------------------------------+------+------------+
| host                                            | user | grant_priv |
+-------------------------------------------------+------+------------+
| %                                               | root | Y          |
| gzns-ecom-baiduhui-201605-m42n02.gzns.baidu.com | root | Y          |
| 127.0.0.1                                       | root | Y          |
| ::1                                             | root | Y          |
| localhost                                       |      | N          |
| gzns-ecom-baiduhui-201605-m42n02.gzns.baidu.com |      | N          |
| localhost                                       | root | N          |
+-------------------------------------------------+------+------------+

 

结果发现本机还是连不上：

$ mysql -P8306 -uroot -p123456
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

再查表看到password这一栏：

mysql> select host, user, Password, grant_priv from user;
+-------------------------------------------------+------+-------------------------------------------+------------+
| host                                            | user | Password                                  | grant_priv |
+-------------------------------------------------+------+-------------------------------------------+------------+
| %                                               | root | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | Y          |
| localhost                                       | root |                                           | Y          |
| 127.0.0.1                                       | root |                                           | Y          |
| ::1                                             | root |                                           | Y          |
| localhost                                       |      |                                           | N          |
| gzns-ecom-baiduhui-201605-m42n02.gzns.baidu.com |      |                                           | N          |
| 127.0.0.1                                       |      | *6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9 | N          |
+-------------------------------------------------+------+-------------------------------------------+------------+

发现localhost和root这一栏，没有密码，所以不用密码才能登录：
