I'm trying to deploy mediawiki to Azure Web App. I created the app using Linux and PHP 7.3. I unpacked WikiMedia 1.35.1 into wwwroot and used the browser to run the installation

I want to use MySQL for Azure as the database. So I enter the mysql.database.azure.com parameters and press install.

The error I get is

```
Cannot access the database: :real_connect(): (HY000/9002): SSL connection is required.

```

The docs say I need to set $wgDBssl to true in LocalSettings.php.

The problem is that LocalSettings.php does not exist yet. How do I specify an SSL connection during installation?
