我创建了数据库,例如'mydb'.

CREATE DATABASE mydb CHARACTER SET utf8 COLLATE utf8_bin;
CREATE USER 'myuser'@'%' IDENTIFIED BY PASSWORD '*HASH';
GRANT ALL ON mydb.* TO 'myuser'@'%';
GRANT ALL ON mydb TO 'myuser'@'%';
GRANT CREATE ON mydb TO 'myuser'@'%';
FLUSH PRIVILEGES;

现在我可以从任何地方登录到数据库,但无法创建表.

如何授予该数据库和(将来)表的所有权限.我无法在'mydb'数据库中创建表.我总是得到:

CREATE TABLE t (c CHAR(20) CHARACTER SET utf8 COLLATE utf8_bin);
ERROR 1142 (42000): CREATE command denied to user 'myuser'@'...' for table 't'

当我运行以下查询时,我收到一个错误:

SELECT
  `a`.`sl_id`                     AS `sl_id`,
  `a`.`quote_id`                  AS `quote_id`,
  `a`.`sl_date`                   AS `sl_date`,
  `a`.`sl_type`                   AS `sl_type`,
  `a`.`sl_status`                 AS `sl_status`,
  `b`.`client_id`                 AS `client_id`,
  `b`.`business`                  AS `business`,
  `b`.`affaire_type`              AS `affaire_type`,
  `b`.`quotation_date`            AS `quotation_date`,
  `b`.`total_sale_price_with_tax` AS `total_sale_price_with_tax`,
  `b`.`STATUS`                    AS `status`,
  `b`.`customer_name`             AS `customer_name`
FROM `tbl_supplier_list` `a`
  LEFT JOIN `view_quotes` `b`
    ON (`b`.`quote_id` = `a`.`quote_id`)
LIMIT 0, 30

错误消息是:

#1449 - The user specified as a definer ('web2vi'@'%') does not exist

为什么我会收到这个错误？我如何解决它？

在Windows XP上运行的MySQL 5.1.31.

从本地 MySQL服务器(192.168.233.142)我可以以root身份连接如下:

>mysql --host=192.168.233.142 --user=root --password=redacted

从远程计算机(192.168.233.163),我可以看到mysql端口是打开的:

# telnet 192.168.233.142 3306
Trying 192.168.233.142...
Connected to 192.168.233.142 (192.168.233.142).

但是当我尝试从远程计算机连接到mysql时,我会收到:

# mysql --host=192.168.233.142 --user=root --password=redacted
ERROR 1045 (28000): Access denied for user 'root'@'192.168.233.163' (using password: YES)

我在mysql.user中只有2个条目:

Host         User     Password
--------------------------------------
localhost    root     *blahblahblah
%            root     [same as above]

我还需要做些什么来启用远程访问？

编辑

正如下面的Paulo所建议的,我尝试用特定于IP的条目替换%的mysql.user条目,因此我的用户表现在看起来像这样:

Host             User     Password
------------------------------------------
localhost        root     *blahblahblah
192.168.233.163  root     [same as above]

然后我重新启动了机器,但问题仍然存在.

为什么哦为什么我不能连接到mysql？

mysql -u root -ptest101 -h xxx.xxx.xxx.xxx
ERROR 1130 (HY000): Host 'xxx.xxx.xxx.xxx' is not allowed to connect to this MySQL server

在my.cnf我有以下内容

# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address        = 0.0.0.0

我也跑了以下......

'UPDATE mysql.user SET Password = PASSWORD('test101') WHERE User = 'root';
FLUSH PRIVILEGES;

我可以使用mysql -u root -ptest101在主机上访问但不能使用mysql -u root -ptest101 -h xxx.xxx.xxx.xxx

哇......为什么会这样？我是ubuntj 12.04

mysql> SELECT host FROM mysql.user WHERE User = …

我刚刚安装了Ubuntu 16.04并在其上安装了Web服务器.一切运作良好,但我无法访问数据库.我在互联网上尝试了一切,也在这里,但没有任何作用......即使我创建新用户并授予所有权限,我也无法创建数据库:(在PHP中我得到'这个错误:

SQLSTATE[HY000] [1698] Access denied for user 'root'@'localhost'

当我尝试登录终端时,它可以工作,但在PHP和phpmyadmin中没有.请帮忙.

PHP代码:

protected $host = '127.0.0.1';
protected $db = 'dbname';
protected $name = 'root';
protected $pass = 'root';
protected $conn;
private static $settings = array(
    PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8'
);

public function __construct() {
    try {
        $this->conn = new PDO("mysql:host=$this->host;dbname=$this->db", $this->name, $this->pass, self::$settings);
    } catch (PDOException $e) {
        echo $e->getMessage();
    }
}

我想向每个主机的用户授予选择权限，但出现错误，您不允许创建用户

mysql>GRANT SELECT ON *.* TO 'alice'@'%' WITH GRANT OPTION;

ERROR 1410 (42000): 不允许您使用 GRANT 创建用户

我不想创建新用户，因为我使用了命令 CREATE USER

我尝试创建一个新用户，但授予命令也失败。

我正在尝试从 Spring Boot 连接 MySQL 数据库，但出现以下错误：
