初心者エンジニアです。
MacでVagrantとVirtualBoxを使用してCentOS7環境を作成する際、vagrant upをすると
以下のエラーが発生します。
最終的には192.168.33.10へ接続してhttpdサーバーへアクセスするとこをゴールとしています。

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

 setup

Stdout from the command:

Stderr from the command:

bash: line 4: setup: command not found

vagrant statusを実行するとrunningと表示されるためvagrantは起動している認識です。

Current machine states:

default                   running (virtualbox)

The VM is running. To stop this VM, you can run `vagrant halt` to
shut it down forcefully, or you can run `vagrant suspend` to simply
suspend the virtual machine. In either case, to restart it again,
simply run `vagrant up`.

現在の状況で192.168.33.10へ接続すると3分ほどのローディング後、
「ページを開けません。ページ"192.168.33.10"を開けません。このページのあるサーバが応答しません。」と表示されます。

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine. In the example below,
  # accessing "localhost:8080" will access port 80 on the guest machine.
  # NOTE: This will enable public access to the opened port
  # config.vm.network "forwarded_port", guest: 80, host: 8080

  # Create a forwarded port mapping which allows access to a specific port
  # within the machine from a port on the host machine and only allow access
  # via 127.0.0.1 to disable public access
  # config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"

  # Create a private network, which allows host-only access to the machine
  # using a specific IP.
  config.vm.network "private_network", ip: "192.168.33.10"

  # Create a public network, which generally matched to bridged network.
  # Bridged networks make the machine appear as another physical device on
  # your network.
  # config.vm.network "public_network"

  # Share an additional folder to the guest VM. The first argument is
  # the path on the host to the actual folder. The second argument is
