Apache config file not working

[SatanicGeek]

Hello everyone !

I'm new to Zabbix and the best way to test and discover this beautiful tool is to install a server. And that's what I did !
Everything went well until I tried to access http://myserver/zabbix

I'm redirected to /zabbix/setup.php and I have this page showing me errors with my config :



After seeing this, I tried to check if the zabbix.conf file exists and if it's in the correct folder (/etc/httpd/conf.d/zabbix.conf) and it's all good.
I changed the timezone and restarted my server.

Aaaaand it's not working. I have the same message when I try to setup the frontend.

I tried a lot of things (chmod, chown, new vhost, changing the config, to install from scratch Zabbix Server) and it's not working.
I tried to search this issue on Google but I cannot find something that can help me.

So, anyone had this issue ?

Here's my setup :

Hyper-V VM
CentOS 7.4 x64 minimal
LAMP (PHP7.3), Webmin, SSH
SELinux=disabled
Zabbix Server 4.0.4 (that's what I have at the bottom of the page)

I don't see anything in the log files.

Can anyone help me ?

Thank you in advance !

Hello, I found the solution !

The problem does not come from Apache or Zabbix config.
It comes from the config file I have inside /etc/httpd/conf,d/zabbix.conf.

This is the default config provided by Zabbix :

#
# Zabbix monitoring system php web frontend
#

Alias /zabbix /usr/share/zabbix

<Directory "/usr/share/zabbix">
    Options FollowSymLinks
    AllowOverride None
    Require all granted

    <IfModule mod_php5.c>
        php_value max_execution_time 300
        php_value memory_limit 128M
        php_value post_max_size 16M
        php_value upload_max_filesize 2M
        php_value max_input_time 300
        php_value always_populate_raw_post_data -1
        # php_value date.timezone Europre/Riga
    </IfModule>
</Directory>

<Directory "/usr/share/zabbix/conf">
    Require all denied
</Directory>

<Directory "/usr/share/zabbix/app">
    Require all denied
</Directory>

<Directory "/usr/share/zabbix/include">
    Require all denied
</Directory>

<Directory "/usr/share/zabbix/local">
    Require all denied
</Directory>

Since I have PHP7.3, I changed the line

<IfModule mod_php5.c>

to

<IfModule mod_php7.c>

Then a simple apachectl restart and it's all good !

<Directory "/usr/share/zabbix">

        php_value max_input_vars 10000
        php_value always_populate_raw_post_data -1
        php_value date.timezone Europe/Zurich
