前回の質問でPythonの検索エンジンを起動したいのですがgoogle chromeでlocalhostにアクセス出来なくて困っています。

mac os sierraにvagrantでubuntu14.04を使用しているのですがWebアプリが動かせないです。  
VirtualenvでPython3を仮想にし以下のモジュールがインストールしてあります。  
2つのターミナルウィンドーを使いvagrant sshで2回 ログインしています。  
_ウィンドー1 Mongdb起動  
ウィンドー2 webページを返すサーバの起動_

virtualboxのhostonlyをいじればアクセスできると聞いたのですがVirtualboxのネットワーク設定でアダプター1はNATっていうのになっていいてアダプター2がホストオンリアダプターになっていました。他の3,4は未割り当てです。  
どうしても自分の環境で検索エンジンを動かしたいので協力して頂けないでしょうか？

question
python python3 vagrant flask
vagrantで起動したubuntuのwebアプリにアクセス出来ない。
# localhost にこだわらない場合

```

    # Create a private network, which allows host-only access to the machine
    # using a specific IP.
    config.vm.network "private_network", ip: "192.168.33.11"
    
```

既に host-only ネットワークでホストとゲストがつながっていますので、  
そのままブラウザから <http://192.168.33.11:9000/> につながります。

# localhost にしたい場合

ポートフォワーディングの設定を追加します。

```

    # 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.
    config.vm.network "forwarded_port", guest: 3000, host: 3000
    config.vm.network "forwarded_port", guest: 9000, host: 9000   # ←この行を追加
    
```

こうすると、ホストの 9000番に接続すると、ゲストの 9000番に転送されます。  
これでブラウザから <http://localhost:9000/> につながります。
