Zabbix-web faults 3.2.4 new web configuration files, nginx or apache, etc. need to have permissions

[root@ops01 include]# rpm -ql zabbix-web |more/etc/httpd/conf.d/zabbix.conf/etc/zabbix/web/etc/zabbix/web/maintenance.inc.php/etc/zabbix/web/zabbix.conf.php......

This example uses nginx

chown   -R nginx /etc/zabbix/zabbix

Php session permission failure

chmod +x /var/lib/php/session/chmod g+x,u+x /var/lib/php/session/
