Debian(Vagarnt)におけるCakePHPの環境構築について（開発サーバにアクセス出来ない）

Question

DebianのVagrantを立ち上げてそこでCakePHPの環境を構築しようと試みている者です．
Cakeにはbin/cake serverという開発環境サーバを立ち上げるコマンドがあると思います．
GuestのVagrantでそのコマンドを実行すると以下の様なプログラムが走りました．

vagrant@debian-jessie:/vagrant/app$ bin/cake server

Welcome to CakePHP v3.3.0 Console
---------------------------------------------------------------
App : src
Path: /vagrant/app/src/
DocumentRoot: /vagrant/rakubo/webroot
---------------------------------------------------------------
built-in server is running in http://localhost:8765/
You can exit with `CTRL-C`

ここでいうlocalhostはVagrant側のことなのでhostマシンのブラウザで確認するには少し工夫が必要だと思いました．以下がVagrantfileです．

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

# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don't change it unless you know what
# you're doing.
Vagrant.configure(2) do |config|
  # The most common configuration options are documented and commented below.
  # For a complete reference, please see the online documentation at
  # https://docs.vagrantup.com.

  # Every Vagrant development environment requires a box. You can search for
  # boxes at https://atlas.hashicorp.com/search.
  config.vm.box = "debian/jessie64"

  # Disable automatic box update checking. If you disable this, then
  # boxes will only be checked for updates when the user runs
  # `vagrant box outdated`. This is not recommended.
  # config.vm.box_check_update = false

  # 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: 8765, host: 8080

  # 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
  # the path on the guest to mount the folder. And the optional third
  # argument is a set of non-required options.
  config.vm.synced_folder "./", "/vagrant", type: "virtualbox"

  # Provider-specific configuration so you can fine-tune various
  # backing providers for Vagrant. These expose provider-specific options.
  # Example for VirtualBox:
  #
  # config.vm.provider "virtualbox" do |vb|
  #   # Display the VirtualBox GUI when booting the machine
  #   vb.gui = true
  #
  #   # Customize the amount of memory on the VM:
  #   vb.memory = "1024"
  # end
  #
  # View the documentation for the provider you are using for more
  # information on available options.

  # Define a Vagrant Push strategy for pushing to Atlas. Other push strategies
  # such as FTP and Heroku are also available. See the documentation at
  # https://docs.vagrantup.com/v2/push/atlas.html for more information.
  # config.push.define "atlas" do |push|
  #   push.app = "YOUR_ATLAS_USERNAME/YOUR_APPLICATION_NAME"
  # end

  # Enable provisioning with a shell script. Additional provisioners such as
  # Puppet, Chef, Ansible, Salt, and Docker are also available. Please see the
  # documentation for more information about their specific syntax and use.
  # config.vm.provision "shell", inline: <<-SHELL
  #   sudo apt-get update
  #   sudo apt-get install -y apache2
  # SHELL
end

ここで問題が発生しました．
Guestの8765portとHostの8080portをポートフォワーディングしたのにもかかわらず，http://localhost:8080にアクセスが出来ないのです．
ちなみに，

• Hostからping 192.168.33.10は通ります
• Hostからping 192.168.33.10:8765はping: cannot resolve 192.168.33.10:8765: Unknown host
• Hostからping localhost:8080はping: cannot resolve 192.168.33.10:8765: Unknown host

vagrant reloadを見る限りポートフォワーディングはできているようなのですが…

どうやったらCakePHPの開発サーバをホストから確認ができるようになるのか，お知恵を貸していただけませんでしょうか？
よろしくお願いいたします．

Answer 1

[メモ]cakephp3のbin/cake serverでvagrantで接続できない問題解決
http://qiita.com/waterada/items/ffd41970bbaf57e19d76

上記のURLに記載してあるように、以下のようにすれば、接続できるようになると思います。

bin/cake server -H 0.0.0.0 -p 8765

Answer 2

その設定で以下の様に起動した場合はどうですか？

bin/cake server -H 192.168.33.10 -p 8765

また、debian側のfirewallや、SELinuxの設定にも気を付けてください。

ufwコマンド（ufw allow 8765）を使って8765ポートを開放してみましたが結果は変わりませんでした．（pingが通らない）
bin/cake server -H 192.168.33.10 -p 8765も同様です．
SELinuxについては初めて聞いたので今調べている最中です．

取り急ぎ報告まで．

私の環境（Ubuntu）では、こちらの方の回答にあるように、

```
bin/cake server -H 192.168.33.100

Welcome to CakePHP v3.3.3 Console
---------------------------------------------------------------
App : src
Path: /home/vagrant/myapp/src/
DocumentRoot: /home/vagrant/myapp/webroot
---------------------------------------------------------------
built-in server is running in http://192.168.33.100:8765/
You can exit with `CTRL-C`
```

ブラウザから、http://192.168.33.100:8765
でアクセスできます。

ポートフォワーディングは、しておりません。

あと、pingでポートが開いているかどうかは確認できませんので。
ping: cannot resolve 192.168.33.10:8765: Unknown host
は当然の結果です。

例えば、Windowsですと、Host(Windows)側からコマンドで

> telnet 192.168.33.100 8888
接続中: 192.168.33.100...ホストへ接続できませんでした。 ポート番号 8888: 接続に失敗しました

となるか、

> telnet 192.168.33.100 8765
→ 画面真っ黒　→　止めると、cake server の方がログを返す。
[Wed Sep 14 11:25:14 2016] 192.168.33.1:52766 Invalid request (Malformed HTTP request)
(つまりは開いている)

というような確認の仕方があります。

[pack]

pingでポート確認ですが、

ping localhost:8080はping: cannot resolve 192.168.33.10:8765: Unknown host

を見ると、ポート指定出来ているようにも見えますが、何かそういうのがあるのですかね？

すみません。話が逸れてしまって。
