After setup can't see anything!

[savagehobo]

I have setup cacti using the setup instructions from the website. I am running Fedora 8 on a Dell Inspiron 6400 laptop. When I navigate to http://localhost/cacti/ I get a blank page. I have tried navigating to http://my-ipaddress/cacti and I get a "You don't have permission to access /cacti on this server" from Apache. I attributed this to permissions but I can see the apache test page if I go to http://localhost. I followed every instruction (except for the freebsd part of the instruction). Any suggestions?

What is the UNIX path to your Apache document root?
What is the UNIX path to your Cacti document root?

Do a
ls -alF /YourApacheDocRootPathHere
and
ls -alF /YourCactiDocRootHere

In your Apache httpd.conf, what is the user and group your web server runs as?

You may need to chown the CactiDocRoot
For example on my system:
chown -R www:www /opt/apache/htdocs/cacti/
Of course on my system the user and group for apache is www

Cacti Location: /usr/cacti/cacti-0.8.7b/
Apache location: /var/www/html/ (i think?)

From httpd.conf

#
# If you wish httpd to run as a different user or group, you must run
# httpd as root initially and it will switch.
#
# User/Group: The name (or #number) of the user/group to run httpd as.
# . On SCO (ODT 3) use "User nouser" and "Group nogroup".
# . On HPUX you may not be able to use shared memory as nobody, and the
# suggested workaround is to create a user www and use that user.
# NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
# when the value of (unsigned)Group is above 60000;
# don't use Group #-1 on these systems!
#
User apache
Group apache


Another interesting twist in this story. So last night I completely removed the mysql, httpd, cacti, and php packages and then reinstalled them and setup cacti again. It worked... I was able to log in and even see some devices. When I woke up this morning and rebooted I now get the blank screen again. Any ideas?

[N3NCY]

From your output, I see your web files are owned by:
root root
meaning user root
and
group root

Your apache httpd.conf is set for
user apache
and
group apache

Look in your /etc/passwd file and see if user apache even exists.
cat /etc/passwd

If the user does not exist, add it with minimal permisions like:
pw groupadd apache
pw useradd apache -n apache -G apache -s /usr/sbin/nologin
Or whatever command you use to add users on your OS

Next I see your cacti is not a subdirectory under your apache root.
This may be as you desired and it is ok if you setup this path in your httpd.conf
Did you?

If not, you may not want this:
/usr/cacti/cacti-0.8.7b/
but instead as a subdir of your apache root like this:
/var/www/html/cacti/

Then you will want to chown the directory:
chown -R apache:apache /var/www/html/cacti/

I managed to get it running again... It appeared that I didn't give the correct path in the php config file. It's running now, but none of the graphs I setup appear. I looked at it and the 0.8.7b version of cacti doesn't seem to work with v1.3.x of rrdtool. So I manually setup the older 1.2.28 version along side of the 1.3.x version (because when I try to remove the 1.3.x version it removes cacti as well). I pointed to the path in the cacti settings (/usr/local/rrdtool-1.2.28/bin/rrdtool) but no graph yet..... any suggestions?

[gandalf]

The rrdtool issue is known and fixed in SVN. Will be published as 087c soon. Until the, please set rrdtool utility version to 1.2 instead

I am using version 1.2.x I have set my 'RRDTool Utility Version" to "RRDTool 1.2.x" but it didn't work. So made sure that the path was set correctly... The RRDTool Binary Path is set to /usr/local/rrdtool-1.2.28/bin/rrdtool This should be correct as it says "OK: FILE FOUND" below the box. But I still don't see any graphs I just see a few arrows, and a magnifying glass beside the large white space that should be the graph. I have restarted my machine after making the changes but to no avail. Has anyone run into this before? I am using Cacti 0.8.7b.

[savagehobo]

I can now see the graphs... the problem was the permissions in the /usr/cacti/cacti-0.8.7b folder... I forgot to set the permissions on the rra/ and log/ folders.
