解决mysqlAccess denied for user'root'@'IP地址'问题

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 | +-------------------------------------------------+------+-------------------------------------------+------------+ 7 rows in set (0.00 sec)

发现localhost和root这一栏，没有密码，所以不用密码才能登录：

$ mysql -P8306 -uroot Welcome to the MySQL monitor. Commands end with ; or \g.
