*/5 * * * * cacti php /var/www/html/cacti/poller.php > /dev/null 2>&1

注意：可以手动运行php /var/www/html/cacti/poller.php进行测试会发现有多WARNING：

PHP Warning:  strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Asia/Chongqing' for 'CST/8.0/no DST' instead in /var/www/html/cacti/include/global_arrays.php on line 640

解决办法是：

# vim /etc/php.ini

date.timezone = PRC

# /etc/init.d/httpd restart
