Going to need more info on that one.

Please post:
How you are editing crontab, and the line in the crontab file
ls -sl /var/www/html/cacti/rra/

output of
php /var/www/html/cacti/cmd.php
Run as the cacti user.

^^^ I ran that as Root hopefully it won't be a problem

[Coeus]

Actually yeah - running as root doesn't help.

Please run the command as it appears in your crontab, as the same user.

Thanks

Carl, I reinstalled Cacti and the Cacti user is now Root.

Heres the "source" output:

Ok, This should not be run as root. Please use cacti or cactiuser as your username.

Then run (change usernames and paths where appropriate - assuming Redhat 9 standard install):

Code: Select all

chown -R cacti:apache /var/www/html/cacti/rra
chown -R cacti:apache /var/www/html/cacti/log
chmod 644 /var/www/html/cacti/rra/*
chmod 644 /var/www/html/cacti/log/*

The rra and log directory _must_ be writable by the same user running the cron job.

Note: Can you post os version please?

Which crontab file are you editing? /etc/crontab or are you using "crontab -e" as cactiuser, they have slightly different semantics. The install process assumes you are using /etc/crontab

Can you also post the output of cmd.php when run as the same user running the cron job.

Thanks

Carl

My friend, I think it is Finally working using Root. Do you think I should Uninstall it and use cacti as user instead?

My OS is RedHat Fedora Core 2

[Coeus]

Good to see :)

Shouldn't be necessary to reinstall, you just need to get the permissions right.

Switch the cron job to cactiuser, the change the permissions on rra/ and log/

Remember with testing - you have up to 5 minutes before you see any data.

Ok, I will try that in a bit

Do I need to Add an user? Because chown tells me that the user is non-existent.

This is a Testing Install, it will work 24/7 on one of our servers. So it is not worth the Hassle if it brokes, don't you think?

[Coeus]

Last I checked the installation instructions for cacti were a little brief in the "add cactiuser to system" part, and easily missed

Yes you do need to add a user cacti(or cactiuser note: I prefer cacti as some commands like ps limit display names to 8 chars) and this was almost certainly the cause of your problems.

For a test installation you probably dont need to worry about switching back to cactiuser

On your next installation, you will probably be able to do it from memory ;)

Hopefully, it is easier once you know how to use a bike
