java - mysql-java-connector 连接被拒绝

Question

我有一个谜要告诉你。

我正在尝试连接到虚拟机上的 mysql 服务器(IP:192.168.60.96，在我自己的计算机上运行，​​通过桥接器连接到网络)。

完整的系统信息:

主持人:

Fedora 20
Virtualbox 4.3.16
Eclipse 4.3
MySql-connector-java 5.1.33

虚拟机:

Debian 6
MySql 5.1.73

Ping 正常 PhpMyAdmin运行OK

这是我想要开始工作的代码:

package sec.tests;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class TestSgbd {

    public static void main(String[] args) {
        // TODO Raccord de m�thode auto-g�n�r�
        String url = "jdbc:mysql://192.168.60.96:3306/secolog";
        System.out.println(url);
        try {
            System.out.println("chargement du driver");
            Class.forName("com.mysql.jdbc.Driver");
            System.out.println("r�cup�ration de la connexion");
            Connection con = DriverManager.getConnection(url,"usecolog","password");
            System.out.println("cr�ation d'un statement");
            Statement requete = con.createStatement();
            System.out.println("execution d'une requete");
            ResultSet resultat = requete.executeQuery("select * from CLIENT");
            while (resultat.next()) {
                System.out.println(resultat.getString(1)+"  "+resultat.getString(2));
                };
            System.out.println("fin");
            }
        catch(Exception e) {
            System.out.println("Exception");
            e.printStackTrace();
            }
    }

}

这是一个异常(exception):

有什么想法吗？

Answer 1

它没有连接到错误的IP，错误消息是在谈论客户端:

java.sql.SQLException: Access denied for user 'usecolog'@'usecolog' (using password: YES)

这意味着 usercolog 无权从 192.168.60.97 IP 连接到您的数据库。您需要为 usercolog 设置权限才能从您的机器 IP 建立连接。

要设置权限，请使用以下命令:

GRANT ALL PRIVILEGES ON secolog.* TO 'usecolog'@'%192.168.60.97' IDENTIFIED BY 'secologuserpassword';
FLUSH PRIVILEGES;
