Issue with Zabbix 3+ on Centos 7 - setup.php

[misant]

Hi!

I installed Zabbix 3.2 (mysql version) on Centos System and met an issue - fronted initial setup was not working, when on http://somehost/setup.php click on "Next Step" nothinh happens.

Server description:
1. Centos 7
2. Nginx + php-fpm
3. mysql

What I tried to change:
1. PHP versions - 5.4, 5.6, 7.1, 7.1 not supported so it showed an error, nothing happens with 5.4, 5.6 on click "Next step"
2. mariadb5.5, mysql5.7
3. Zabbix versions 3.0, 3.2 with same result

Also I installed new server from scratch and got same issue:

http://45.77.52.249/setup.php

No any errors on nginx, php-fpm or zabbix logs.

SOLVED:
Ownership change was needed:

chown -R nginx:nginx /var/lib/php/session/

Which users did you want nginx and php-fpm to work on?

If you made it work with nginx users, you need to change the permissions of the various files.
For example, the following files and directories.

$ ls -ld /var/lib/php/session/
drwxrwx--- 2 root apache 44  5月 23 18:28 /var/lib/php/session/
$ ls -ld /etc/zabbix/web/
drwxr-x--- 2 apache apache 54  4月 27 11:00 /etc/zabbix/web/
$

Both nginx and php-fpm are started with "nginx" user

That helped!
Thank you a lot, with no errors in logs I spent a lot of time to fix it without success. I changed ownership of /etc/zabbix/web, zabbix frontend dir but never met that session folder mentions.

chown -R nginx:nginx /var/lib/php/session/

If you are running as an nginx user, please check whether the nginx user can access PHP session management directory.
Similarly, you need to check the permissions of the /etc/zabbix/web/ directory.
