Mesmo com Wordpress instalado, ainda aparece a Apache2 Ubuntu Default Page

Nas aulas anteriores, o Wordpress funcionou normal. Mas quando separou, mesmo com todas as configurações (aparentemente) certinhas, a página do apache insiste em aparecer.

Este é meu provisioning.yml

Se eu vou na url direta (http://172.17.177.40/wp-admin/install.php), aparece

Not Found The requested URL /wp-admin/install.php was not found on this server.

Alguém consegue me ajudar?
