cacti的rrdtool画不出图来的问题

1 习惯性的把rrd的文件rm -rf *掉了，发现cron过了好多次都没画出图来
2 检查权限，权限ok的,cron的执行用户和/var/www/cacti/rra目录的拥有者是同一个用户

bear@njava:/var/www/cacti/rra$ sudo vi /etc/crontab
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user  command
17 *    * * *   root    cd / && run-parts --report /etc/cron.hourly
25 6    * * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
47 6    * * 7   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.weekly )
52 6    1 * *   root    test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.monthly )
*/5 * * * * www-data php /var/www/cacti/poller.php > /dev/null 2>&1

3 把Poller Type由spine改成cmd.php，奇迹发生了，图被画出来了，之后再改回spine,运转正常
