CentOS7.8 之前从7.5升级
PHP7.2 之前从5.4升级
MariaDB 10.3.23 之前从5.5升级
Zabbix 4.2版本 之前从4.0升级上来的) 理论应该可以4.0直接升级到4.4或5.0
升级完成遇到两个问题：
- 一.登Zabbix网页提示
current database version (mandatory/optional): 04030046/04030046
required mandatory version: 04040000
解决：登陆mysql -u root -p
update dbversion set mandatory=4040000;
flush privileges;
问题一解决
- 二..登陆Zabbix网页会提示
