最近？はやりのReactive Programmingの環境として、PlayFramework2をインストールしてみました。vagrantのcentos7上に構築しています。
なんのことはないタダのVagrantfile
Vagrant.configure(2) do |config|
config.vm.box = "centos7"
config.vm.network "private_network", ip: "192.168.33.10"
config.vm.synced_folder "./data", "/vagrant", create: true
end

おっ動いてますね。CLIでなく、GUIですとactivator uiでかっこいいWebUIが表示されます。ちょーべんり。

PlayFrameworkをインストールする
早速Playをインストールしたい。ｳｽﾞｳｽﾞ
list-templatesでテンプレートを選びます。
play frameworkのテンプレートを探します。
console
$ activator list-templates | grep play | grep scala

console

Fetching the latest list of templates...
OK, application "play" is being created using the "play-scala" template.
To run "play" from the command line, "cd play" then:
/home/vagrant/play/activator run
To run the test for "play" from the command line, "cd play" then:
/home/vagrant/play/activator test
To run the Activator UI for "play" from the command line, "cd play" then:
/home/vagrant/play/activator ui
console
$ cd play
$ ls
LICENSE activator-launch-1.3.7.jar build.sbt project test
README activator.bat conf public
activator app logs target
playディレクトリにactivatorが入ってるので、さっきパスを通したactivatorではなく、こちらのアプリケーションごとに作成されるactivatorを使用します。
console

かなり時間がかかった。activatorコンソールが起動されました。
console
[play] $ run
--- (Running the application, auto-reloading is enabled) ---
[info] p.c.s.NettyServer - Listening for HTTP on /0:0:0:0:0:0:0:0:9000
(Server started, use Ctrl+D to stop and go back to the console...)
runでサーバを起動できます。このときにNode.jsをインストールしておくとassetsのコンパイルが早くなるらしい。また、consoleと入力すると、scalaのREPLが立ち上がります。
http://192.168.33.10:9000 にアクセスして、こんな感じの画面が出てくれば、一旦Playのインストールは完了です。
拍子抜けするほど簡単でした。なんかもうちょっと、アレをインストールして...そしたらこれの依存関係があって...みたいなものだと思ってました。Scalaの勉強を時間見つけてやってみたいですね。
