How to connect to a MySQL server running on a Virtual Machine

Question

I have a MySQL Server 5.5.32 running on Ubuntu 12.04. Ubuntu is being run on VM. Host platform is Windows 7. How can I connect with the Ubuntu's MySQL from Windows?

I have done the following so far:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;

FLUSH PRIVILEGES;

Running a show grant for root; displays this:

+-------------------------------------------------------------+
| Grants for root@%                                           |
+-------------------------------------------------------------+
| GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION |
+-------------------------------------------------------------+

But when I try to connect to this server from SQLYog running on Windows, I get an error Error 2003 Cannot connect to mysql server on '192.168.xxx.xxx' .

The IP being feed to SQLYog, I got it from ifconfig . Supplied the inet addr.

inet addr:192.168.226.xxx  Bcast:192.168.226.yyy

Is the address being used is incorrect or are these grant issues? Please advice.

Answer 1

You problem is that (probably) your mysql is bind to 127.0.0.1 instead of 0.0.0.0 .

You should change bind in /etc/mysql/my.cnf to 0.0.0.0

bind-address = 0.0.0.0

And then restart mysql of course.

Answer 2

In newer versions of MySQL, instead of skip-networking the default is now to listen only on localhost bind-address = 127.0.0.1

So you need to add your machine IP to here or simply comment it out if you are not worry about security concerns.

Answer 3

The error message Error No. 2003: Can't connect to MySQL server on 'localhost' (or some other host)

simply means that connection is not possible for one of the following (or similar) reasons:

• There is no MySQL server running at the specified host

• Connection to the MySQL server is not allowed using TCP-IP. Check the 'skip-networking' setting in the MySQL configuration file (my.ini on Windows, my.cnf on Unix/Linux). It shall be commented out like '#skip-networking'. If it is not commented out, then do it and restart the MySQL server for the change to take effect. SQLyog needs to connect using TCP-IP.

• Some networking issue prevents connection. It could be a network malconfiguration or a firewall issue. We have experienced sometimes that some firewalls is blocking TCP-IP connections even if it claims to be disabled. Most often it will help to uninstall and reinstall the firewall.

• When trying to connect to a MySQL server at an ISP this error message often indicates that direct connection to MySQL has been blocked. You must then use HTTP-tunneling or SSH-tunneling to connect.

Answer 4

I think the problem is with the Network Adapter settings in your VM settings

Do like this in your VM settings.

VM Settings -> Network Adapter Settings -> Select Bridged

The VM will connect to the physical network when the network connection is on bridged mode .

Try to ping the VM host in your windows machine after changing the network connection to bridged .

If the VM is pinging in your windows machine then it will work.

Error No. 2003: Can't connect to MySQL server on '192.168.x.x'

simply means that connection is not possible for one of the following (or similar) reasons:

• There is no MySQL server running at the specified host

• Connection to the MySQL server is not allowed using TCP-IP. Check the 'skip-networking' setting in the MySQL configuration file (my.ini on Windows, my.cnf on Unix/Linux). It shall be commented out like '#skip-networking'. If it is not commented out, then do it and restart the MySQL server for the change to take effect. SQLyog needs to connect using TCP-IP.

• Make sure that you are able to connect to MySQL port using telnet

  C:\\telnet hostname/IP_address port
