Slow MySQL Connection with VPN
But still except for the last part, the other information is right. Make a vpn connection from the client remote to the intended network host 2. I managed to install it and get it working already. I also added the following parameter to my MySQL config: When the client establishes a connection to the server, the server checks the client certificate against the CA certificate for validity. Get paid for your work.

Implementing a VPN connection to a MySql database

Obviously, it is good to pick a better password than I have. You may also want to limit the database a user is able to connect to or from which host a user is allowed to connect. We still need to be on the MySQL server in order to set up the client, though.

A private key and certificate for the client need to be generated on the server, as that is where the CA certificate and private key reside. Just like before, we start with a private key and a certificate signing request:. Which is all there should be to it. If the connection is successful, you should be connected to MySQL. In times where privacy is a more and more important topic, securing your connections between your servers is a great idea.

Compared to classical VPN tunnels it was more robust and less error-prone and you have one layer less to troubleshoot. The security is comparable — if done right. The approach by using an own private CA as described by Maarten is the best you can do in my opinion. Just take care to keep the CA private key safe, i.

I also added the following parameter to my MySQL config: This works for me on Debian Wheezy so it will probably work on a much newer Ubuntu Then the server does not only rely on the password but also requires the connecting client to present a valid certificate issued from a trusted CA. This means that finally only your own mysql server and not everyone else on the internet can connect — and maybe brute-force the password. Just another approach you can do instead of restricting the user access to certain IP addresses which is fine as well.

Even Multi-Master setups with more than 2 servers in ring architectures are possible though they have some limitations. Of course this goes beyond the scope of this great tutorial, but just to give you an idea of what you can do if you want to do more. I was uncertain whether I had to go into SSL and replication, but I decided not to in order to limit the scope of this tutorial.

It may be material for a future tutorial, though: Thanks for the tutorial! It would be great to read on this topic. Just wanted to pop by and say I for one would be very interested in a tutorial going over SSL certificates and security.

How do you make a self-signed one? Good companies to provide a proper certificate? Thank you for your suggestion. But I hope you will continue mysql, I am really looking forward to something in the lines of clustered mysql.

Would be fantastic if you did. I thought an attacker would not be able to logon to the server without using the right certificate and therefore not be able to use brute force you cannot not brute-force a certificate, right Or have I misunderstood something?

The last part of this post is obviously wrong. You need to indicate where are the client-key. And also some important details missing and I suggest you practice a little bit to figure out what is the correct way.

But still except for the last part, the other information is right. I was not able to verify usage of my. Your email address will not be published. Next, generate the certificate using that key: Now, export the private key into an RSA private key: To apply these changes, restart MySQL: Just like before, we start with a private key and a certificate signing request: When that has been done, we need to install the MySQL client on the client server: To see if all we did works, try and connect to your server: But the mysql port is probably still not listening on this interface, because it only listens to On both your local machine and your server open a terminal window.

On the server type "ifconfig" and on the windows machine type "ipconfig" the spelling idffers in the 2nd character and the machines tell you the adresses of all their adapters.

You can now see which one is the additional vpn adapter on both machines they have similar addresses. If you don't want to change the setting of the serer you can "forward" the port, which is a different technique and can be done with ssh or putty.

You will have to make a ssh or putty connection from your local machine to the server and forward port on IP If you are using putty go to the ssh tunneling section and add a local port forwarding After the ssh or putty connection is active you have to tell your mysql administration software to connect to localhost so you put Be sure not to run a mysql service on your local box at the same time.

You mentioned that you loose the connection to your server when you create the tunnel. This is probably a security restriction of the tunneling software. But you should still be able to connect through the tunnel with the mysql admin tool. But may be mysql is only listen locally, in this case you will need to connect to the server using ssh and run mysqladmin locally or you may use things like phpmyadmin.
