I setup a Windows 7 on vm
on the same pc
, I have a form with the following code:
MySqlConnection connection = new MySqlConnection("SERVER = 127.0.0.1; DATABASE = my_test; UID = root; PASSWORD = 'XXXX';");
private void Form1_Load(object sender, EventArgs e)
{
MySqlCommand cmd = new MySqlCommand("SELECT * FROM info", connection);
connection.Open();
MySqlDataReader reader = cmd.ExecuteReader();
if (reader.HasRows)
{
while (reader.Read())
{
MessageBox.Show(reader[1].ToString());
}
}
reader.Close();
connection.Close();
}
on my pc
i successfully connect to the db, now i copy and paste my app to the vm and i get a jit
error i don't have any thing on the vm
(no appache
no mysql
nothing but net framework 4.0) i did make my root user remote enabled like that:
GRANT ALL ON *.* to '%'@'%' WITH GRANT OPTION;
now i still stuck, so how to connect to the db with my ip
so the vm
can find it, and do i need to setup anything in the vm
?
Note: i can use another pc
if the problem in the VirtualBox
but i suspect that it has nothing to do with the VirtualBox
.
i am confused i made this form
and i move it to the vm and i asking simply: what to write in that textbox?
When you connect to 127.0.0.1
, you connect to the current system. Regardless of what system is running: main or vm
. You should configure network settings of the VirtualBox
so that vm
can connect to your main system. In this case you'll connect from vm
not to localhost but to IP-address that you set to main OS
.
Or you can setup MySQL
to the vm
and move your database to that MySQL
.
EDIT
For testing connection to MySQL
you can use telnet
( http://windows.microsoft.com/en-us/windows/telnet-faq#1TC=windows-7 ). At first you should know the MySQL
port. You can get it from MySQL
config or try ports from @Prageeth Roshane' answer. Then you should try to connect from VirtualBox
to MySQL
to finded port. You can use or programm or telnet. If you'll have troubles with connections, try to check that the firewall in VM and in main OS is not blocked your programm (or telnet).
PS If you can connect to MySQL
from another PC, but cann't connect from VM, then trouble is in VM's network settings.
给您的mysql连接正在使用的PORT
,例如3308或3306
