  1. The robot didn’t notice that the service is called mysql in ubuntu 16.04, and that php 7.2 does not include mcrypt.

  2. thanks for the work !
    just a question, “step 7”, i didn’t get “the commands also disable PHP7.0 and enable PHP 7.1 for Nginx.”
    “the commands” = creating the symlink ?
    why PHP 7.1 ?
