New insatll ... web page not rendering

[mcdougak]

Hey all,

So I just finished installing from scratch on a new server using the instructions provided here: https://www.zabbix.com/documentation..._from_packages

But when i navigate to http://servername/zabbix I'm looking at a blank page. I know the web service is functioning correctly because when i go to just http://servername/ I can see the default apache page.

Am I missing anything? I've restarted all services and modified the configs as necessary to point to the correct DB server. I'm not getting any errors on the screen, just a blank page ...

Thanks in advance for your help!
KM

Did you restart/reload apache?

Please check if apache is working properly (check access and error logs), after that check that PHP is working properly (Google for php info)

[mcdougak]

Yes, restarted the apache service ... looked at logs and found this ...

Would seem like a permissions issue but I'm not sure where to go from here. Not really a linux guy. I had a test environment setup on Ubuntu and it worked perfectly but now that I've moved to RHEL6 I'm running into all kinds of errors.

Can you paste the output of:

# ls -la /etc/zabbix/web/maintenance.inc.php

[mcdougak]

ls: cannot access /etc/zabbix/web/maintenance.inc.php: Permission denied

[mcdougak]

sorry that was with my reg user acct ...

here is what i get with sudo ...
-rw-r--r--. 1 root root 1036 Dec 10 09:45 /etc/zabbix/web/maintenance.inc.php

[EnigmA-X]

Please make sure that /etc/zabbix/web/ is accessible for the account running the apache server (normally httpd,apache or www-data)

So also check permissions on the directories:

/etc (should be fine)
/etc/zabbix
/etc/zabbix/web

By the way, I'm utterly surprised about the lack of Filesystem Hierarchy Standard (FHS) compliance on this subject. These webfiles do not belong in /etc/ in the first place. I will check it out and will file a bug-report if this is really true...

Don't think that the default install will place the web frontend files into /etc/$WHATEVER.
It's most likely a "configure --sysconf-dir=..." with a malformed "--prefix=/" parameter. The default for --prefix is "/usr/local".

[mcdougak]

modified permissions and get the following in error_log for httpd

here is the permissions on the file:
-rwxr-xr-x. 1 apache apache 1036 Dec 10 09:45 /etc/zabbix/web/maintenance.inc.php

It's most likely a "configure --sysconf-dir=..." with a malformed "--prefix=/" parameter. The default for --prefix is "/usr/local".

What do it need to do then? Do I need some kind of pointer or something in my /etc/httpd directory?

Sorry guys for all the dumb questions ... still learning linux and how it works

[steveboyson]

I would suggest that you do yourself a favour and grab the (hopefully) existing packages for $YOUR_DISTRO.

Otherwise: if you placed the web frontend files under /etc then an
Alias /zabbix "/etc/zabbix/web"
would at least be needed. And then fix the "Directory /usr/share/zabbix" statements to the location you've been chosen.

But better have your web frontend files under /usr/share/zabbix as it is the default.

[steveboyson]

By the way: the link you mentioned does nothing say about self-compiling zabbix.
What distribution are you using? Could it be that these packages are really BROKEN?

Correct I did not compile I installed from the RPM as suggested for RHEL6 (that's what I'm running it on).

So I would ** assume ** (could totally be wrong) that everything would be already configured to be put in the correct place ?

[steveboyson]

I had a look on the RH 6 packages. The only file they place there is "maintenance.inc.php" which is perfectly fine.

Is your RH 6box somehow reconfigured to use SeLinux or AppArmor or any other security-hardening package?

That would explain your probs. I just cannot imagine that the RH6 packages are broken.

[steveboyson]

Addendum: the apache config provided by the RH6 RPM seems to be OK for me. It's pointing to /usr/share/zabbix as expected.


I really don't know what's wrong with your install.
