脚本针对的是zabbix2,x，我用的是zabbix3.x ，表结构发生了变化
变化如下：
mysql> show create table history_logG;
*************************** 1. row ***************************
Table: history_log
Create Table: CREATE TABLE `history_log` (
`id` bigint(20) unsigned NOT NULL,
`itemid` bigint(20) unsigned NOT NULL,
`clock` int(11) NOT NULL DEFAULT '0',
`timestamp` int(11) NOT NULL DEFAULT '0',
`source` varchar(64) NOT NULL DEFAULT '',
`severity` int(11) NOT NULL DEFAULT '0',
`value` text NOT NULL,
`logeventid` int(11) NOT NULL DEFAULT '0',
`ns` int(11) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`), #zabbix3.x 没有这两行了，可是分表的时候，修改的就是这两行
UNIQUE KEY `history_log_2` (`itemid`,`id`),
KEY `history_log_1` (`itemid`,`clock`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
mysql> show create table history_text G;
*************************** 1. row ***************************
Table: history_text
Create Table: CREATE TABLE `history_text` (
`id` bigint(20) unsigned NOT NULL,
`itemid` bigint(20) unsigned NOT NULL,
`clock` int(11) NOT NULL DEFAULT '0',
`value` text NOT NULL,
`ns` int(11) NOT NULL DEFAULT '0',
PRIMARY KEY (`id`), #zabbix3.x 没有这两行了，可是分表的时候，修改的就是这两行
UNIQUE KEY `history_text_2` (`itemid`,`id`),
KEY `history_text_1` (`itemid`,`clock`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
我使用的方法是（我的zabbix是全新的）
删除这两个表，新建了符合脚本的表，这样搞后，分表成功了，测试也没法问题，但是不知道后续会不会出什么问题，不知道这两行的作用。
脚本如下：
根据自己的实际环境，脚本要修改三个地方
1.数据库的用户名和密码 默认是 zabbix zabbix
2.zabbix_server.conf的路径 默认是 /etc/zabbix/
3.修改数据存放目录
4.. /etc/init.d/zabbix-server 控制文件要存在 并且就是这个名字
中途 切莫轻易中断脚本，容易导致表数据损坏
检查完毕后执行脚本
脚本执行如下：

以上是针对一个新的zabbix的时候，如果是一个工作有段时间的zabbix，数据库里的数据量较大，执行时间天知道有多长，建议先清空历史数据（情况前完整来个备份吧）
