Permission Deneid: Driving me crazy!

Post by LJMorpheus »

Cannot view live graphs as RRDTool will not execute, everything else 100% fine. Exported Graphs are fine.

/var/log/httpd/error.log
sh: /usr/local/rrd/bin/rrdtool: Permission denied

/var/log/messages
dbcnetmon kernel: audit(1116505275.562:0): avc: denied { execute } for pid=27620 exe=/bin/bash name=rrdtool dev=dm-0 ino=5706076 scontext=root:system_r:httpd_sys_script_t tcontext=root:object_r:usr_t tclass=file

Permissions on all files are perfect, does anyone know how to fix this - I have spent almost 2 days just trying to figure out why RRDTool fails to execute.

Sudo as the user and manually running the RRDTool and generating images into the Cacti rra folders works fine.

Is Apache/PHP stopping the execution? I cannot see anything in php.ini and I have relaxed my Apache so mush I cannot think of anything else.

Your Apache service account need rw to both the log and rra folders. It also require rx to the rrdtool binary folder.

RRDTool is installed under /usr/local/rrd, currently set to 777 cacti installed to /var/www/html/cacti also set-to 777.

I have now go so far as to run apache as the cacti user! and re-set the ownership to rrdtool and html to cacti, still same error

I wish I could help further. I am not a *nix person per se. You will be able to overcome this as thousands of users have this product running in *nix. I wish you the best of luck.

Permissions are not quite correct on the files or your SELinux policy is wrong.
Download and install the source policy, and in the source directory add the following to domains/misc/local.te:
allow httpd_sys_script_t usr_t:file execute;

(got this config line by piping your message to audit2allow)
Then run make reload. That should be it.

If you need more details, let me know.

Not too sure. You might want to e-mail Rony for more assistance.

Could you post the output of:
"ls -la /var/www/rrdtool/bin/"

and

"file /var/www/rrdtool/bin/rrdtool"

Thanks.
