I hope you read my articles related to Virtual Machines in azure. If not, please read those. I was being limited to use only 20 MB size since one of the MSDN subscription was providing me ClearDB. So I thought of creating a virtual machine and install MySQL. Then I restored my previous Database to my new Database. Here in this article, I will share you the steps to link the database you created to azure virtual machine and wordpress.

Steps to Back Up your ClearDB and restore

Hope you have already installed MySQL in your Virtual Machine. If so, we are ready to go.

First thing we need to do is to add the end points in our Azure virtual machine. To do so you need to follow the below steps.

Add end points in Azure virtual machine

Go to your virtual machine in azure management portal.

Adding end points in Azure Virtual Machine

Now click on the end points as shown in the preceding image.

Now you will be getting a pop up, in that please click on the Add standalone end points.

Adding end points in Azure Virtual Machine

In the given area, please select MySQL as name and TCP as protocol. Port should be the one we did it while configuring the MySQL. For example 3306. I suggest you to do not edit in that area.

Click on the tick icon once you have made entry for the required fields. Then you can see the progression and once it is completed, you will get a message as follows.

Go to the start menu and type power shell. You will be given some search results.

For your convenience I am giving the command as below.

[sql]

You can type the command as shown below.

You can rename the pasted file, just right click on the file and click rename.

As you can see in the below image, I have given the name as ClearDB-Wp-Config.php.

Now add the port number in the host name because it listen that port.
