Zabbix FrontEnd Issue

[uncram]

Rhel 7.3 box and install Zabbix for first time. Install, db setup, and server conf go find. Use PHP info page also works. But when try to Get 404 for Frontend. Zabbix logs say success. This is my first install so when I re-read and got to the configure php part this is below. Problem is it never made a .conf in httpd. So I do have it working on centos and copied over, still won't work. My thinking is the install tell Apache more to do with Zabbix than just this config file. So how do I replace or fix or replace?


— Configuring PHP For Zabbix
The Zabbix web interface is written in PHP and requires some special PHP server settings. The Zabbix installation process created an Apache configuration file that contains these settings. It is located in the directory /etc/httpd/conf.d/ and is loaded automatically by Apache. We need to make a small change to this file, so open it up.


Below is my .conf I copied. Again I can post httpd logs or Zabbix but it says successful startup and http just shows me requesting the zabbix page that wont load. Php info works fine. Can I just copy a good copy of the .conf into httpd and what does that look like for Rhel7.3 updated?

Update

Apache = 2.4.6
Zabbix = 3.2
RHEL 7.3
PHP = 5.4.16

I installed by using RPM. Just need to know if you can easily copy a .conf file into Apache and it will work. Or does the rpm install add some other system hooks?

Ok I did a yum remove zabbix-my-sql and it removed the httpd.conf.d zabbix.conf file. Then I reinstalled and it looks like a new clean version.

Still get 404 when accessing frontend. Phpinfo is still working.

This is httpd access log:

No help at all...

After more than 80 views no one even made a comment at all...

I resolved this by copying the /usr/share/zabbix to /var/www/html/zabbix
set group and permissions. Hope this helps someone else.

If you do not run with Zabbix's package installation with the RHEL 7.3 standard package configuration, you probably have changed from the default settings.

If you do not provide information that you have set yourself, it is difficult to identify the problem.

If a 404 error has occurred, the contents of access_log and error_log output at that time are also useful for identifying the cause.

[LenR]

So you get the Zabbix setup web screens, but not the dashboard?

If you're not getting the setup screens, did you restart the web server after the zabbix frontend install? Standard install would create /etc/httpd/conf.d/zabbix.conf that points to the frontend.

(file/path from memory)

Does the default Apache splash page load? (Server url without /zabbix)

[LenR]

Also, what install doc are you following? I've seen people follow blog posts that are wrong. If it's not vendor, don't trust it :-)

Dear LenR


I was able to reproduce the issue on ubuntu 17.04 and zabbix 3.4.
I've followed this installation manual https://www.zabbix.com/documentation...ion_with_mysql since there is no documantation for 3.4 version.

The solution is to append into
sudo vim /etc/apache2/apache2.conf

the following line with zabbix configuration directory:
IncludeOptional conf-available/*.conf

I have also tried the solution offered by unicram, it worked as well, but apache then has read the default configuration file with improper variables for zabbix. Hope this will help someone.
