Installing Magento 2 on Dedicated Server Painful

Why is installing Magento 2 so painful? When I last installed version 1 many years ago it was seamless. Now I cant get past the most basic of stages on a dedicated server despite meeting all the requirements?

Other websites run just fine but I cant for the life of me get Magento 2 installed very easily and when I do its awfully slow with a default store.

Why…?
