Apache2 crashes on Ubuntu Linux 22.04.5 after Zabbix was updated to 7.0.26

During a upgrade of my Ubuntu server there was a new package for Zabbix 7.0.26 (maybe also apache2, unknown by me).

Apache2 stops working so did Zabbix.

Apache2 complains about Apache 'ProxyTimeout 300' found in /etc/apache2/conf-enabled/zabbix.conf

On my system following Apache2 modules wasn't running

proxy, proxy_http, proxy_fcgi

So try to enabled them first by running in bash.

sudo a2enmod proxy 

sudo a2enmod proxy_http 

sudo a2enmod proxy_fcgi

Then restart Apache2 using:

sudo systemctl restart apache2

Now check if Apache and Zabbix is up and running.

I also modified the /etc/apache2/conf-enabled/zabbix.conf, maybe not needed. I add the new data in zabbix.conf:

# Define the alias so /zabbix points to the correct folder

Alias /zabbix /usr/share/zabbix

<Directory "/usr/share/zabbix">

    Options FollowSymLinks

    AllowOverride None

    Require all granted

    <IfModule mod_php.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 max_input_vars 10000

        # Replace the timezone below with your actual timezone

        php_value date.timezone UTC

    </IfModule>

</Directory>

<Directory "/usr/share/zabbix/conf">

    Require all denied

    Require all denied

</Directory>

<Directory "/usr/share/zabbix/local">

    Require all denied

</Directory>

# The line that was causing your original error

 ProxyTimeout 300

If you updated zabbix.conf then restart apache2 again

sudo systemctl restart apache2
