我有Raspberry Pi,IP = 192.168.137.165,我的Windows笔记本电脑IP = 192.168.137.1。我编写C#代码从我的笔记本电脑连接MySQL。

我也在ras PI上更改了文件my.cnf,如下所示:

   #bind-address = 127.0.0.1
   bind-address = 0.0.0.0

在MySQL上,配置为允许从任何IP地址进行访问:

   GRANT ALL PRIVILEGES ON luan_van.* TO 'root_b'@'%' IDENTIFIED BY 'root';
   flush privileges;

这是我的C#代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using MySql.Data.MySqlClient;

namespace bp_3
{
    public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void btn_connect_Click(object sender, EventArgs e)
    {
        try
        {
            string constring = "Server=192.168.137.165;Database=luan_van;Port=3306;User ID=root_b;     Password=root";
            MySqlConnection conDataBase = new MySqlConnection(constring);
            MySqlDataAdapter myData = new MySqlDataAdapter();
            myData.SelectCommand = new MySqlCommand("select * from tt_nhanvien;", conDataBase);
            MySqlCommandBuilder cb = new MySqlCommandBuilder(myData);
            conDataBase.Open();
            MessageBox.Show("Connect");
            conDataBase.Close();
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
}
}

错误“无法获取您地址的主机名”

它有什么问题,我该如何解决?

答案 0 :(得分:1)

您可以在conf文件中使用它

[mysqld]
skip-name-resolve 

这应该可以解决问题
