linux环境下安装mysql数据库遇到的问题

总结一句话：

安装完mysql数据库记得授权远程登录。

 

坑的现象：

ERROR 1045 (28000): Access denied for user 'guoxp'@'localhost' (using password: YES)

 

解决方案如下：

执行前查看状态：

MariaDB [mysql]>  select Host,User,Password from user ;

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

| Host                  | User  | Password                                  |

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

| localhost             | root  |                                           |

| localhost.localdomain | root  |                                           |

| 127.0.0.1             | root  |                                           |

| ::1                   | root  |                                           |

| localhost             |       |                                           |

| localhost.localdomain |       |                                           |

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

6 rows in set (0.00 sec)

 

 

授权：

MariaDB [mysql]> grant select,update,insert,delete on *.* to guoxp@远程登录的ip地址 identified by "远程登录的密码";

Query OK, 0 rows affected (0.00 sec)

 

执行后查看状态：

MariaDB [mysql]>  select Host,User,Password from user ;

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

| Host                  | User  | Password                                  |

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

| localhost             | root  |                                           |

| localhost.localdomain | root  |                                           |

| 127.0.0.1             | root  |                                           |

| ::1                   | root  |                                           |

| localhost             |       |                                           |

| localhost.localdomain |       |                                           |

| 远程登录的ip地址        | guoxp | *FA074CDA355DAA0D0E53ABE2885985ECEB743D7A |
