mysql ERROR 1045 (28000): Access denied for user的解决方法

问题描述：

今日在10.240.210.60上面远程连接10.240.210.188的数据库时，弹出以下报错

mysql ERROR 1045 (28000): Access denied for user

上网搜索后了解到，是由于10.240.210.188没有给10.240.210.60这台机器赋予连接权限引起的。

【解决办法】

1. 在10.240.210.188连上mysql
   

   [root@openvas ~]# mysql -uroot -ppassword

2. 赋予10.240.210.60连接权限

   1）查看权限信息
   

   mysql> show grants;
   +----------------------------------------------------------------------------------------------------------------------------------------+
   | Grants for root@localhost                                                                                                              |
   +----------------------------------------------------------------------------------------------------------------------------------------+
   | GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY PASSWORD '*83947472A627808D9FC03023210C4C369F0CAA5D' WITH GRANT OPTION |
   | GRANT PROXY ON ''@'' TO 'root'@'localhost' WITH GRANT OPTION    
   2）赋予相应权限

   mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'10.240.210.60' IDENTIFIED BY PASSWORD '*83947472A627808D9FC03023210C4C369F0CAA5D' WITH GRANT OPTION;

   Query OK, 0 rows affected (0.00 sec)
   
   mysql> flush privileges;     刷新数据库
   Query OK, 0 rows affected (0.00 sec)

3. 重新连接即可
