旧密码验证不再被支持，使用4.1风格的密码 [英] Authentication with old password no longer supported, use 4.1 style passwords

问题描述

我有我的网站，HostGator的，我想访问与C＃Windows应用程序的MySQL数据库，但是当我试图连接得到了这样的信息：

I have my website with hostgator and I want to access mysql database with C# windows application but when I tried to connect got this message:

旧密码认证不再被支持，使用4.1风格
  密码

"Authentication with old password no longer supported, use 4.1 style password"

我曾尝试给出的解决方案：

I have tried given solution:

SET SESSION old_passwords=0;
SET PASSWORD FOR user@host=PASSWORD('your pw here');

第一次查询成功执行，但我当第二个查询执行拒绝访问用户@主机的错误。我不明白为什么会出现这个问题。我使用的MySQL连接器网6.6.5。

first query executed successfully but I got the error "Access denied for user@host" when second query executed. I can't understand why there is this problem. I am using MySQL-connecter-net 6.6.5.

我成功地使用MySQL工作台47年2月5日连接我的数据库。

I successfully connect my database with MySql workbench 5.2.47.

谁能帮我，我可以做更多？

Can anyone help me what I can do more?

我联系我的托管网站，并更改my.cnf文件使用4.1风格的密码。和我能够与MySQL连接

I have contact my hosting site and they make changes to my.cnf file to use 4.1 style password. and i am able to connect with mysql

mysql -u <username> -p <password> -h <hostname>;

但是当我试图用C＃与MySQL连接器6.6.5网络连接，我再次得到这个错误。

but when i tried to connect with C# with mySQL connecter net 6.6.5 i again got this error.

我在Windows 8 64位使用Visual Studio 2012与MySQL连接器6.6.5。这是code I用于连接

I am using Visual Studio 2012 with MySQL connector 6.6.5 on Windows 8 64 bit. this is the code i used to connect

using MySQL.Data.MySQLClient;

private void button1_Click(object sender, EventArgs e)
            {
                string connStr = String.Format("server={0};port={1};uid={2};password={3};database={4}",
                    txtserver.Text, txtPort.Text, txtUser.Text, txtPassword.Text, txtDatabase.Text);
                conn = new MySqlConnection(connStr);
                try
                {
                    conn.Open();
                    MessageBox.Show("Test Connection Succeded");
                }
                catch (MySqlException ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }

我不明白问题出在哪里。请帮我

I can't understand where the problem is. Please Help me

推荐答案

我有同样的问题。在我的情况下，只需运行该命令低于工作台连接在我的数据库：

I had the same problem. In my case just ran the command below connected on my database by the Workbench:

SET SESSION old_passwords=0;
SET PASSWORD FOR my_user=PASSWORD('my_password');

之后，我可以用connnect的MySQL Connector 6.6.5在C＃code与普通MySQL连接字符串：

After that I could connnect using MySql Connector 6.6.5 in the c# code with the common mysql connection string:

"server=my_server_ip;user=my_user;database=my_db;port=3306;password=my_password;"
