Question

我需要使用远程mysql服务器访问数据库，但是当我尝试它时，我收到这样的错误：

SQLException: Access denied for user 'u121252012_iya'@'114.79.63.156' (using password: YES)
SQLState: 28000
VendorError: 1045

这是我的连接代码：

package Include;
import java.sql.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
/**
 *
 * @author Ruslan
 */
public class Koneksi {
    private static Connection koneksi;

    public static void main (String []args){
        Connection conn = null;
try {
    conn =
       DriverManager.getConnection("jdbc:mysql://my_ip_server/u121252012_coba?" +
                                   "user=u121252012_iya&password=qwertyu");

    // Do something with the Connection

} catch (SQLException ex) {
    // handle any errors
    System.out.println("SQLException: " + ex.getMessage());
    System.out.println("SQLState: " + ex.getSQLState());
    System.out.println("VendorError: " + ex.getErrorCode());
}
    }


}

拜托，我需要您的帮助来解决它。

Answer 1

CREATE USER '<username>'@'%' IDENTIFIED BY '<pwd>';

此处％表示允许用户从所有IP进行访问。此外，您可能还需要向用户授予权限

GRANT ALL PRIVILEGES ON *.* TO '<username>'@'%' WITH GRANT OPTION;

而且，连接机制应该是这样的。

 conn = DriverManager.getConnection(<DB_URL>,<USER>,<PASS>);

所以改变

 conn =
        DriverManager.getConnection("jdbc:mysql://my_ip_server/u121252012_coba?" +
                                   "user=u121252012_iya&password=qwertyu");

到

 conn =
        DriverManager.getConnection("jdbc:mysql://my_ip_server/u121252012_coba?",
                                   "u121252012_iya","qwertyu");

为什么连接到远程mysql服务器时出错？
