【手順】

①Apacheモジュールを有効可する
有効化対象は、cgid。
$ sudo a2enmod cgid

②mime.confを編集し、拡張子「.cgi」がcgi-scriptをして処理されるよう設定する
$ cd /etc/apache2/mods-enabled/
$ sudo vi mime.conf

220行目付近にある
#AddHandler cgi-script　を
  AddHandler cgi-script　へ。

③設定ファイルを変更しCGIを有効化する設定とする

<Directory "/var/www/html">
                AllowOverride All
                Options ExecCGI Multiviews Indexes IncludesNoExec
        </Directory>

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html
        <Directory "/var/www/html">
                AllowOverride All
                Options ExecCGI Multiviews Indexes IncludesNoExec
        </Directory>

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

④文法チェック
$ apachectl configtest

⑤再起動
$sudo service apache2 restart
