Температура воздуха в г.Георгиевск

===== Создание графика температуры с помощью RRDTool - rrdcgi ===== Веб-сервер, у меня Apache.\\ Добавляю в **/usr/local/etc/apache22/httpd.conf** следующие строки для обработки cgi скриптов Alias /term "/usr/local/www/term/" Options FollowSymLinks ExecCGI AddHandler cgi-script .cgi DirectoryIndex index.cgi AllowOverride None Order deny,allow Allow from all Директория /usr/local/www/term – являеться корневой для термометра.\\ Создадю ее # mkdir /usr/local/www/temperature Назначаю права на созданную директорию # chown www:www /usr/local/www/temperature Рестартую apache # apachectl restart Т.к. RRDTool ставиться при установки cacti и отрисовка температуры у меня уже осуществляется, то я использую базу данных cacti. Создаю cgi скрипт

  # cat > /usr/local/www/term/index.cgi
  #!/usr/local/bin/rrdcgi
