Pay attention to upgrade
You must be very careful when upgrading from a previous version to Zabbix 5.0.
Packages in Red Hat Software Collections are designed to avoid file conflicts with files in the primary repository.
Each package is installed in a separate environment dedicated to its group.
 

System environment

cat  /etc/redhat-release 
CentOS Linux release 7.6.1810 (Core)
nginx   -vnginx 
version: nginx/1.16.1

Preparation before upgrading

Official upgrade document

https://www.zabbix.com/documentation/5.0/manual/installation/install_from_packages/frontend_on_rhel7

  

At the beginning of Zabbix 5.0.0beta1, PHP version 7.2 and above is required for the front-end. Currently, Centos 7 only provides PHP 5.4. ZABBIX officially recommends using PHP and Nginx in Red Hat Software Collections to upgrade Zabbix 5.0.0beta1. If you upgrade with repo.zabbix.com package, you will find that the front-end package is missing from yum search.
