升级需注意

从以前的版本升级到Zabbix 5.0时必须格外小心。

Red Hat Software Collections中的软件包旨在避免与主要存储库中的文件冲突。

每个软件包都安装到专用于其组的单独环境中。

系统环境

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

升级前准备

官方升级文档

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

Zabbix 5.0.0beta1 版本开始前端需要使用PHP 7.2以上的版本，目前使用的Centos 7 仅提供PHP 5.4,Zabbix 官方建议使用Red Hat Software Collections中的PHP和Nginx 升级Zabbix 5.0.0beta1。在使用repo.zabbix.com软件包进行升级会发现yum 搜索缺少前端软件包。
