创建新的zabbix server （mysql）容易，最后一条日志报错

cannot usedatabase"zabbix": its "users" table is empty (is this the Zabbix proxy database?)

往前还有一条关键报错信息

ERROR 1153 (08S01): Got a packet bigger than 'max_allowed_packet' bytes

mysql默认最大只能处理16M的文件，手动临时调整到512M（重启数据库后失效）

set global max_allowed_packet=524288000;

检查是否正确生效

show VARIABLES like '%max_allowed_packet%';
