zabbix3.2 报错 Database error

一、Database error
The frontend does not match Zabbix database. Current database version (mandatory/optional): 3020000/3020000. Required mandatory version: 3040000. Contact your system administrator.

解决办法：

进入数据库

mysql> show databases;
mysql> use zabbix;
mysql> update dbversion set mandatory=3040000;
mysql> flush privileges;

重新打开web即可解决
