Determine web server root folder in Vagrant

Question

Follows my Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

Vagrant.configure("2") do |config|

    config.vm.box = "scotch"
    config.vm.network "private_network", ip: "192.168.33.107"
    config.vm.hostname = "scotchbox"
    config.vm.synced_folder "../public/", "/var/www", :mount_options => ["dmode=777", "fmode=666"]

    # Optional NFS. Make sure to remove other synced_folder line too
    #config.vm.synced_folder ".", "/var/www", :nfs => { :mount_options => ["dmode=777","fmode=666"] }

end

I am doing to meet the following directory structure:

-| D
---| Projetos
-----| PHP
-------| 5
-------| 7
-------| public

Where in the PHP directory, I have different machines with different php versions, and in the same folder I have the public, where I’ll put my projects, the idea is to share this directory as my own /var/www of all machines, in my theory Vagrantfile is working, the machine turns on normally, but when accessing the IP of it by the browser is given the 404 Not Found, what can be?

The way out of mine vagrant up is:

PS D:\Projetos\PHP\7> vagrant up

Note: I have already determined permissions for the Windows "All" group.

Answer 1

I found out that the box scotch, edit the shared folder name by adding a /public on the way, soon would be:

D:/Projetos/PHP/public/public, so I altered ../public/ for ../ and it worked.
