How to partition the installation of Linux to consider how to take the test?

For the list of Centos7 folders that use the minimized installation, note that the linked folder will not be counted when the statistics occupy space;

Take a look at the Footprint (link folder does not appear)

Ok here, do you know how much each is enough?

Here again look at the use of a few years of regular online webserver folder (Ubuntu)

Take a look at the space occupied (with mysql,nginx,php)

Take a look at the occupancy in VAR (MySQL data is in Lib, www is site with some related backup)

Var/www There's nothing more to say.

Take a look at other things besides MySQL, which occupy more

No more eyes on the Ali go to the server

Ok. Is it possible to know how to divide it here?

Use it long enough. Or look at other people's role. Server. It's very easy to know how to divide.
