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
