参考: https://www.zabbix.com/documentation/current/manual/installation/upgrade_notes_500 在Mariadb选择zabbix库后执行命令 https://git.zabbix.com/projects/ZBX/repos/zabbix/raw/database/mysql/double.sql mysql -u root -p use zabbix; 复制下面命令 ALTER TABLE trends MODIFY value_min DOUBLE PRECISION DEFAULT '0.0000' NOT NULL, MODIFY value_avg DOUBLE PRECISION DEFAULT '0.0000' NOT NULL, MODIFY value_max DOUBLE PRECISION DEFAULT '0.0000' NOT NULL; ALTER TABLE history MODIFY value DOUBLE PRECISION DEFAULT '0.0000' NOT NULL;
修改 vi /etc/zabbix/web/zabbix.conf.php 添加 $DB['DOUBLE_IEEE754'] = true; 重启zabbix服务 systemctl restart zabbix-server
