Nextcloud multiple errors using Install script, Sql, Root vs User

Software SW help
1

I have run into countless errors trying to use the Install_nextcloud script.

  1. Do i use the Install_nextcloud script as root or user?

  2. If you do it as root whats the deal with running mysqlD as root?

Any help would be greatly appreciated, after hours of research and exhausting every thread on here, I am at a standstill.

Installed also as root but it seems it is not running as root:
