How to Setup Azure MySQL In App

Azure MySQL In App

Microsoft Azure has added a neat feature to App Services called MySQL In App. This feature allows you to host a MySQL instance inside of the resources of your App Service Plan you are already paying for. This is a great feature for setting up a blog or having a small database handy local to your website, API or WebJob. Note that the product was released in 2016, but Azure still recommends that it only be used for small workloads and not production systems due to the auto scale not being supported and a few other factors.

Start in Microsoft Azure App Services

To set up MySQL In App, all you have to do is open your blade for your App Service, scroll under the Settings header to MySQL In App and click on it. Then click On under MySQL In App on the pane.

Once you do this, you just have to wait a few moments and your MySQL In App will be ready for you to use. You’ll see something like this below when it is ready for you to use. Notice that your Connection string environment variable is called MYSQLCONNSTR_localdb. We will go find this file soon. Also notice the Manage link at the top of the pane. This will take you to phpMyAdmin, which is a handy tool for managing your MySQL database.

Tweak your Azure App Service

Next, you will want to go ahead and enable Always on, under your Configuration -> General Settings as if this is not set, the system will shut down your database during periods of inactivity and it may not come back up when the server is woken back up.

Get MySQL connection information

Finally, you’ll want to go ahead and retrieve a few pieces of information that will be helpful for you. First, click Manage to open phpMyAdmin. It’ll pop open a new window with the phpMyAdmin tool. Notice at the top of the window it’ll display the IP and port number your database is running on. You’ll want to copy this information. The database is only accessible from this machine, so the IP is 127.0.0.1, but the port follows that like in the image below.

Get your port number from the phpMyAdmin tool

Now go get your username and password. This information is in the MYSQLCONNSTR_localdb.ini file in d:\home\data\mysql as we saw in the MySQL In App pane earlier. To get this file, the best way is to go to Advanced Tools on the blade for your App Service.


Advanced Tools

Once here, you click Go in the Pane and this opens Kudu Services in a new tab. In here, click on Debug console at the top and choose CMD. Type in

cd d:\home\data\mysql

and press enter. This will take you to the path and you’re GUI list will load above the console window. Here you can download the file, open it with Notepad and get your username and password from the connection string stored inside.

Put Azure MySQL In App to use

Now that you have the IP, port, username and password, you are prepared to install whatever software you want, like WordPress or Drupal, or build your own custom software and take advantage of having a local MySQL database there to work with.

As you can see, this new tool is easy to setup and once you have the parts you need you are ready to go! Happy coding!
