nothing....I mean, it executes the script ... wanna see the output?

DeathRipple · Post by **DeathRipple** » Fri Jan 21, 2005 9:40 am

the good news is that i'm not getting anything in cacti.log when executing as cactiuser

Please post the output.

Also, double check the permissions.

Sorry, I know I'm repeating myself.

What do you have the shell set to for cactiuser?

DeathRipple · Post by **DeathRipple** » Fri Jan 21, 2005 9:50 am

[root@teste cacti]# cat /etc/passwd | grep cacti
cactiuser

500:500::/home/cactiuser:/bin/bash

Ok, I'm stumped....

I see nothing wrong with your cron entry, other than not specifying the full path. Which you said you have tested. Even if the shell is set to /bin/false cron will still execute entries in the /etc/crontab for that user, because it has a shell set.

So, I'm at a loss.

The only things I can say is make sure you are using the full path to php and make sure that your permissions on the logs and rra directory are correct.

Other than that, it's has to be an issue with cron, I would focus there.

the problem is that the files are already created, but no update....

so, should this have something to do with my distribution? I mean, the php version, mysql, httpd....etc. net-snmp and rddtool are the latest available...

Again, if root can update them, it's a permission issue. The cactiuser has to be able to update the files in the rra and log directory. Typically, you set the owner of the directory and files in the directory to cactiuser.

Run the following in your cacti installation directory.

Code: Select all

chown -R cactiuser log rra

I know of many users using FC2 and not having problems. So, no I don't think so, the fact that is runs as root is an indication that it is working. Again, it think its a permission issue or a cron issue.

The fact that you don't see any entry in the cron log that poller is being executing is perplexing me.

[root@teste cacti]# ls -al | grep rra
drwxrwxrwx 2 cactiuser users 4096 Jan 21 14:39 rra
-rw-r--r-- 1 root users 6068 Dec 19 22:01 rra.php
[root@teste cacti]# ls -al | grep log
-rw-r--r-- 1 root users 6133 Dec 19 22:01 auth_login.php
drwxrwxrwx 2 cactiuser users 4096 Jan 21 17:11 log
-rw-r--r-- 1 root users 1796 Dec 19 22:01 logout.php

I've even tried to run the cron job as root, with same result....I'm stuck too. it's must be a stupid thing that I'm missing

Sorry if you covered this, did you install cacti from the source, or from a package?

Because from the source, your will have a log and rra directory in the root of the cacti installation.

If they are else where, you need to locate them and check there permissions.

DeathRipple · Post by **DeathRipple** » Fri Jan 21, 2005 10:49 am

the only rra and log dirs are located inside the cacti dir and nowhere else. I've installed from tar.gz.

/boggle

But if you run it as root, it updated the rrds?

DeathRipple · Post by **DeathRipple** » Mon Jan 24, 2005 2:02 am

yup...it does. and i've changed the line in cron, so it will be run not as cactiuser, but as root.....still, no change...

DeathRipple · Post by **DeathRipple** » Mon Jan 24, 2005 5:48 am

reinstalled cacti on a new, fresh FC1 - it seems it works?!?!

don't know for sure yet....have to let it run for a day or so....at least /var/log/cron looks OK

DeathRipple · Post by **DeathRipple** » Mon Jan 24, 2005 8:48 am

local it's working.....at least for now....
next problem....it's not working right with another remote linux machine.... the graph is shown, but no update is made...
