linux - Giving Apache2 write access to a user directory

I want to give Apache2 write access to a directory in a users home directory so it can write logs etc.

The idea is that I add Apache2 to the users group:

sudo usermod -aG vagrant www-data

And then I simply give the directory to which I want Apache2 to be able to write "group" write and execute permissions:

chmod g+wx ./logs

However, this does not seem to work.

How do I add Apache2 to a users group and set the permissions correctly for write access?
