New insatll ... web page not rendering

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.

From sestatus:
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: permissive
Mode from config file: permissive
Policy version: 24
Policy from config file: targeted

Oha. That explains a lot. Probably you need to teach selinux to allow you to start and run zabbix. Unfortunately I can't help you with that since I'm not using it.

Probably aunt g00gle does know more about it?

Ok, will do some research on selinux or ask one of our linux guys here ...
I'll report back what I find when I find something.

It would seem like selinux being in 'permissive' mode would allow me to do what i need ....
I just did an remove and reinstall and got the same outcome (checking for errors during install i may have missed).
I do, however still receive the same permission error in the error_log for httpd ... so maybe selinux is messing with that somehow ...

anyways, thanks all, i'll let you know what happens.

Your selinux settings should be fine.

As asked before, what is the output of:

# ls -la /etc/zabbix

Correct permissions

Just created an account to give a solution to this old thread.
I have been struggling with the same HTTP Error 500 after each Zabbix update:

PHP Fatal error:  require_once(): Failed opening required '/etc/zabbix/web/maintenance.inc.php'

1) Well, the solution is simple - the folder /etc/zabbix/web/ belongs to the group "apache".
You can add the user, under which you run your Zabbix web-interface, to the group "apache" with:

usermod -a -G apache YOUR_ZABBIX_WEB_USER

You will have to restart apache or httpd for the permissions to take effect.

2) Alternatively - the folder /etc/zabbix/web/ has permissions 750 after each update.
So you can give broader permissions 755:

chmod 755 /etc/zabbix/web/

and your Zabbix web-interface will come back to life immediately.
But you will have to fix folder permissions after each update, so the first method is preferable.
