Frontend Installation - Blank Screen

[p.reinboth]

Hi Guys,

I wanted to give Zabbix a try but I'm having trouble with the installation. I got everything up and running but I only get a blank screen when I visit my site to to the frontend installation. It does redirect me to the setup.php though.

Further information on my setup:
I am using nginx and mariadb on CentOS 8. I followed the installation instructions I got here: https://www.zabbix.com/download?zabb...centos&os_vers ion=8&db=mysql&ws=nginx

I did make a few changes though: I enabled a 301 redirect in the nginx zabbix.conf to enforce https, I changed the name of the database (I changed the name in the zabbix.conf too, don't worry) and changed the user for the php socket to zabbix too.

Troubleshooting steps I have already taken:
I made sure that I have all necessary php pre-requisites as listed here under step 2: https://www.zabbix.com/documentation...lling_frontend
I checked via phpinfo() that php-fpm is working correctly
I checked the zabbix_server.log and the zabbix_agentd.log for errors but it all seems good to me.
I checked my nginx error log, where I caught the following:
2020/04/16 14:58:27 [error] 2282#0: *16 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught Exception: Cannot start session. in /usr/share/zabbix/include/classes/core/CSession.php:46


Do you guys have any ideas what I might be doing wrong?

In your php-fpm pool, are you setting a location for the sessions, and assuming you're using the 'file' session save_handler, is the directory writable by the 'zabbix' user (since that's who your php-fpm is running as)?

That did the trick, thank you very much
