Go to sys pref -Energy

Slide the Computer and display sliders all the way to the right (to the never position)


If you prefer you can use the build in (by Apple) Terminal command "Caffeinate" to set specific non sleep modes.

To temporarily stop your Mac from sleeping, you could use Caffeine, a widely-used, free utility available both through the App Store as well as a direct download from the developer's site.
