===== インストール  =====

==== cpanm  ====

依存モジュールのインストールにcpanmが必要なので、事前にインストールします。
<code>
# cd /root
# mkdir bin
# cd /bin
# curl -LOk http://xrl.us/cpanm
# chmod 755 cpanm
</code>

==== HRForecast  ====

<code>
# cd /etc/
# git clone git://github.com/kazeburo/HRForecast.git

==== 依存モジュール  ====

<code>
# cd HRForecast
# cpanm -n -lextlib --installdeps .
--> Working on .
～省略～
69 distributions installed
</code>

==== MySQLにテーブル作成  ====

<code>
mysql -u root -p

mysql> create database hrforecast;
mysql> use hrforecast;
mysql> SOURCE /etc/HRForecast/schema.sql
ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes
Query OK, 0 rows affected, 2 warnings (0.01 sec)

ERROR 1071 (42000): Specified key was too long; max key length is 1000 bytes
</code>

付属のテーブル作成スクリプトファイルを実行すると上記のようにエラーになるので、スクリプトファイルのテーブル定義を編集する。
<code>
# cp schema.sql schema.sql.org
# vi schema.sql
:%s/255/111/g
</code>

編集後、再度実行。
<code>
mysql> SOURCE /etc/HRForecast/schema.sql
Query OK, 0 rows affected, 2 warnings (0.00 sec)

Query OK, 0 rows affected, 3 warnings (0.01 sec)

Query OK, 0 rows affected, 2 warnings (0.00 sec)
</code>

==== 初期設定  ====

<code>
# vi config.pl

{
    dsn => 'dbi:mysql:hrforecast;hostname=127.0.0.1',
    username => 'root',
    password => 'password',
    port => '5127',
    host => '0.0.0.0',
    front_proxy => [],
    allow_from => [],
};
</code>

==== 起動確認  ====

以下コマンド実行後、
<code>
# perl hrforecast.pl --config config.pl >> /var/log/hrforecast.log 2>&1 &
</code>
ブラウザから以下にアクセスできることを確認。
<code>
http://サーバ:5127/
</code>

==== 起動スクリプト  ====

起動スクリプトは付属していないので、作成する必要がある。
<code>
# vi /etc/init.d/hrforecast
</code>

<code>
#!/bin/sh
# chkconfig: - 80 20
# description: HRForecast

# Source function library.
. /etc/rc.d/init.d/functions

<code>
# chmod +x /etc/init.d/hrforecast
# /etc/init.d/hrforecast start
</code>

==== データ登録  ====

numberとdatetimeにパラメータをつけて、サーバのAPIにリクエストを投げる。

<code>
# curl -F number=33 -F datetime=20130728T00:00:00 http://localhost:5127/api/mona/regist/all
</code>

===== Tips =====

==== レンジの追加 ====

グラフのレンジに「1日間」を追加
