Bug 198569

Was this an upgrade from a non-fedora to a fedora package?

At one point I had a different cacti, but the current install checks out:

[root@wind ~]# rpm -V cacti
S.5....T. c /etc/cacti/db.php
S.5....T. c /etc/cron.d/cacti
S.5....T. c /etc/httpd/conf.d/cacti.conf
.......T.   /usr/share/cacti/lib/rrd.php
S.5....T.   /var/lib/cacti/scripts/ss_host_disk.php
S.5....T.   /var/log/cacti/cacti.log

My guess is that php has started resolving __FILE__ to the actual location on
disk, not the name the program was started with.

The reason for the split is because of FHS standards.  These files have all been
properly linked back to /usr/share/cacti so they should work.  I haven't been
able to recreate this error.  I'm guessing there was an upgrade issue from the
other RPM.  Is there any way you could try re-creating this on a fresh install?

The reason is simple - symlinks are used to break up the install, but some of
the paths needed for these scripts to work are not symlinked.

As an example, here's what happened when I executed lmsensors scripts I added:

 /usr/bin/php -q /usr/share/cacti/scripts/netsnmp_lmsensors.php fan ana.amantes,
public, 1, , , 161, 500 query sensorDevice
PHP Warning:  include(/var/lib/cacti/scripts/../include/config.php): failed to
open stream: No such file or directory in
/var/lib/cacti/scripts/netsnmp_lmsensors.php on line 18
PHP Warning:  include(): Failed opening

PHP Warning:  include(/var/lib/cacti/scripts/../lib/snmp.php): failed to open

PHP Fatal error:  Call to undefined function cacti_snmp_walk() in
/var/lib/cacti/scripts/netsnmp_lmsensors.php on line 245

the lib and include dirs are in /usr/share/cacti/ and not symlinked to
/var/lib/cacti like the scripts.

[root@onzenbak cacti]# ln -sf /usr/share/cacti/include/ /var/lib/cacti/
[root@onzenbak cacti]# ln -sf /usr/share/cacti/lib /var/lib/cacti/ 

these two commands fixed it for now; it would be good to verify that the split
was done correctly, and if any other mistakes were made, and an update made.

I meant to follow up but haven't had time to do a full report.  Suffice to say
that I can reproduce on a fresh install.  I fully agree with comment #4.

Fresh install on what OS?

(In reply to comment #6)
> Fresh install on what OS?

FC5 with FC5 package.

Thanks, did the fix in comment #4 work for you?

The links fix part of the problems.

Other issues:

# /usr/bin/php -q /usr/share/cacti/scripts/ss_host_disk.php
alexandria.cora.nwra.com 3 '2:161:500:cora0201:::MD5::[None]' index
sh: /usr/bin/snmpbulkwalk: No such file or directory

Looks like cacti should Require net-snmp-utils

Also, selinux issues:

Changing the context of /var/lib/cacti/scripts (and contents) to
httpd_sys_script_exec_t helps, but then I'm stuck on trying to get it to allow
it to read the include and lib links:

Sorry this has taken so long.  I've added the symlinks as well as updated to
release i.  Please re-open this ticket if these issues are not fixed.
