cacti不能显示图像，rra下没有文件！权限，PATH，snmpwalk没问题

itxiaofei

装好了cacti，登录进去，发现不能显示图像
主要问题是rra下死活不能生成*.rrd文件
centos 4.4 ，rrdtool-1.0.50，mysql-4.1.20-1.RHEL4.1，cacti0.8.6i，cacti0.8.6j都试过

参考了http://bbs.chinaunix.net/viewthread.php?tid=648262

另外，1：除了监控linux本机，还建了一个host监控winxp，同样图像出不来。（winxp的snmp装了，snmpwalk同样没问题）
2：cacti0.8.6j解压后权限很奇怪，即使我chown root.root cacti-0.8.6j，chmod -R 777 cacti-0.8.6j也不能运行php，cp出来就可以
drwxr-xr-x  11 1000 users 4096 Jan 18 08:23 cacti-0.8.6j

请求大家帮忙。

通常情况下，cacti是以web服务的用户来运行的，因此在cacti目录下的log 和 rra 目录及其下的所有文件的所有者应该设置为那么用户（比如www-data)。

因此：
chown -R www-data.www-data $CACTIPATH/log
chown -R www-data.www-data $CACTIPATH/rra

chmod 755 $CACTIPATH/log
chmod 755 $CACTIPATH/rra

还有，如果你用root用户运行过cmd.php，那么有可能在rra目录下生成了拥有者为root的一些rrd文件，你需要将这些文件的所有者改成运行www服务的那么用户。

死活不写入。开始怀疑是php的问题了

mcaser

我也是这个问题

rra和log都是cacti组，cacti均有权限写入，但就是不能生成文件

郁闷坏了

mcaser

rra目录下不能生成文件，同时，device下面的设备状态也是down，一直不能up，是不是和rra文件生成有关系

我也遇到这个问题，提示类似这样：

1. RRDTool Says:
2. ERROR: opening '/var/www/html/cacti/rra/xxxx.rrd': No such file or directory

rrdtool没装好，看看少了什么
