<p>JenkinsもVPS上にやってるので最終的にはHerokuへの自動デプロイまでやったことの流れ
(ついでに勉強したことのノート)</p>
<h2>環境</h2>
<ul>
<li>CentOS 6.5</li>
<li>ruby 2.0.0dev</li>
<li>rails 4.0.2</li>
<li>postgreSQL 9.3</li>

<h4>Note : <code>--database=postgresql</code> == <code>-d postgresql</code></h4>
<blockquote><p>—database=postgresqlオプションを入れた時と入れない時の違いは結構あるので注意</p>
<p><a href="http://qa.atmarkit.co.jp/q/2970">rails new project -d postgresql を指定した時に変更される部位</a></p></blockquote>

<p>どうせあとでちょっといじってまたbundle installする</p></blockquote>

<h3>プロキシのメリット</h3>
<ul>
<li>実際に通信するのはプロキシなので、PC側が安全</li>
</ul>
<h2>リバースプロキシ</h2>
<ul>
<li>プロキシはPC側がやるもの、リバースプロキシはWebサーバー側がやるもの</li>
</ul>
<h3>リバースプロキシのメリット</h3>
<ul>
<li>実際に通信するのはリーバスプロキシサーバーを通すようにするので、Webサーバ側の安全性があがる</li>
