< my($OBJECTS) = "$NAGIOS/log/objects.cache";# if defined, use nagios2 cache
---
> my($OBJECTS) = "/var/log/nagios/objects.cache";# if defined, use nagios2 cache

５）schedule.cfg作成

cgi経由でhttpdプロセスが更新するので、オーナーはhttpdプロセスの実行ユーザーを指定。

# touch /etc/nagios/schedule.cfg
# chown apache:nagios /etc/nagios/schedule.cfg
# chmod 664 /etc/nagios/schedule.cfg

ここまで設定すれば、利用可能。
nagiosを再起動して動作確認へ。
