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 [root@shvm01 ~]# rpm -qa |grep zabbix zabbix-release-4.4-1.el7.noarch zabbix-web-4.4.7-1.el7.noarch zabbix-server-mysql-4.4.7-1.el7.x86_64 zabbix-web-mysql-4.4.7-1.el7.noarch zabbix-agent-4.4.7-1.el7.x86_64 [root@shvm01 ~]# mysql -V mysql Ver 14.14 Distrib 5.7.29, for Linux (x86_64) using EditLine wrapper
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.

Extended range of numeric (floating point) values
Numeric (floating-point) data types now support about 15 bit precision, ranging from about - 1.79E + 308 to 1.79E + 308 (except PostgreSQL 11 and earlier). For new installations, this is the default. For an upgraded installation, a manual patch must be applied.
