我正在开发一个用于使用数据库创建zabbix服务器的项目，因此我想使用来自zabbix网站的外部脚本对zabbix服务器的数据库表进行分区，但是我面临着这个问题：
Oct 24 09:27:01 itit_mdbsrv01 mysql_zbx_part[31702]: Partitioning for "history_str" is not found! The table might be not partitioned.
这是我在数据库服务器上运行的脚本

我确实向my.cnf文件中添加了一些曲目
[mysqld]
innodb_buffer_pool_size = 256M # take ~75% of total available memory, for example if you have 8GB of RAM then set it to 6G
innodb_buffer_pool_instances = 4
innodb_flush_log_at_trx_commit = 0
innodb_flush_method = O_DIRECT
innodb_log_file_size = 256M
query_cache_type = 0
innodb_io_capacity = 2000 #or 3000 in SSD scenario
我确实通过脚本（例如syslog和DateTime）安装了所有必需的软件包，并且它是连接并访问数据库的问题，但是问题是当它尝试创建分区时 ps：已启用mariadb分区，并且我使用了它和内部脚本进行了此操作，并且效果很好
