Steps to reproduce the issue

Attempt to install with non localhost.

• Goto installation
• Add non localhost database server config.
• Delete the temporary file.
• Progress to installation.
• Installation just stays still.

Expected result

That after I have already deleted the file, the final installation should work flawlessly.

Actual result

It just werls around and makes thousands of requests indefinitely as shown below.

How I got it working

Whilst the progress bar was still making requests I updated the following file and it continues immediately.

Updated /installation/model/database.php

-                 if (!in_array($options->db_host, $localhost))
+                 if (false)

System information (as much as possible)

• PHP 7.1
• Apache
• MySQL 5.7
