<h4>
設定
</h4>
<p>
Ubuntu側で設定します。設定には、
</p>
<ol>
<li>
mysql サーバ自身に外部からアクセスできるようにする設定
</li>
<li>
mysql 上で設定したユーザーがデーターベースに接続できるようにする設定
</li>
</ol>
<p>
の二種類があります。
</p>

参考にしたサイトにはこんなことが書いてありました:

<p>
調べてみると、以下の箇所を修正する必要がある様だ。
</p>
<ol>
<li>
MySQL Serverの設定ファイルmy.cnfを開き、[mysqld]の項目以下の、bind-addressを探す。
</li>
<li>
bind-addressを、コメントアウトする。
</li>
</ol>
<p>
修正し終わったら、MySQL Serverを再起動すると、外部ホストからも接続可能となる。

というわけで、 /etc/mysql にある my.cnf を編集します。

<h4>
mysql 上で設定したユーザーがデーターベースにアクセスできるようにする
</h4>
<p>
とりあえずローカルなネットワークはこのような構成です:

<a href="http://flickr.com/photos/42332031@N02/4083965175/" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://flickr.com/photos/42332031@N02/4083965175/', '');" title="network configuration"><img src="http://farm3.static.flickr.com/2542/4083965175_48e188704a.jpg" /></a>
</p></p>
<p>
というわけで、192.168.11のネットワークからアクセスできるように設定します。
