MyCat分库分表--实战09--按单月小时

项目环境：

192.168.8.30 mycat

192.168.8.31 node1

192.168.8.32 node2

192.168.8.33 node3

三个节点MySQL均为单实例

一、创建测试库

node1

create database testdb01;create database testdb02;create database testdb03;create database testdb04;create database testdb05;create database testdb06;create database testdb07;create database testdb08;create database testdb09;create database testdb10;create database testdb11;create database testdb12;

node2

create database testdb13;create database testdb14;create database testdb15;create database testdb16;create database testdb17;create database testdb18;create database testdb19;create database testdb20;create database testdb21;create database testdb22;create database testdb23;create database testdb24;

node3

create database testdb25;create database testdb26;create database testdb27;create database testdb28;create database testdb29;create database testdb30;create database testdb31;create database testdb32;create database testdb33;create database testdb34;create database testdb35;create database testdb36;

二、配置schema.xml

                                                                                                                                                                                                                                                                                                                                                                    select user()                                                                select user()                                                                select user()                                        

三、配置rule.xml

                                       adddate                        sharding-by-hour                                               24        

24每天24份

四、启动mycat

/usr/local/mycat/bin/mycat start

查看mycat日志

STATUS | wrapper  | 2018/11/23 12:54:18 | --> Wrapper Started as DaemonSTATUS | wrapper  | 2018/11/23 12:54:19 | Launching a JVM...INFO   | jvm 1    | 2018/11/23 12:54:19 | OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=64M; support was removed in 8.0INFO   | jvm 1    | 2018/11/23 12:54:23 | Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.orgINFO   | jvm 1    | 2018/11/23 12:54:23 |   Copyright 1999-2006 Tanuki Software, Inc.

五、登录MySQL查看逻辑表

mysql -uroot -pmysql -P8066 -h292.168.8.30

mysql> show databases;+----------+| DATABASE |+----------+| mycatdb  |+----------+1 row in set (0.02 sec)mysql> use mycatdbReading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changedmysql> show tables;+-------------------+| Tables in mycatdb |+-------------------+| user04            || user05            || user06            || user07            |+-------------------+4 rows in set (0.01 sec)mysql> drop table if exists user07;Query OK, 0 rows affected, 1 warning (0.38 sec)mysql> create table user07(    -> id int not null,    -> name varchar(64),    -> adddate varchar(10)    -> );

六、插入测试数据

insert into user07(id,name,adddate) values(1,'steven','2018110100');insert into user07(id,name,adddate) values(1,'steven','2018110101');insert into user07(id,name,adddate) values(1,'steven','2018110102');insert into user07(id,name,adddate) values(1,'steven','2018110103');insert into user07(id,name,adddate) values(1,'steven','2018110104');insert into user07(id,name,adddate) values(1,'steven','2018110105');insert into user07(id,name,adddate) values(1,'steven','2018110106');insert into user07(id,name,adddate) values(1,'steven','2018110107');insert into user07(id,name,adddate) values(1,'steven','2018110108');insert into user07(id,name,adddate) values(1,'steven','2018110109');insert into user07(id,name,adddate) values(1,'steven','2018110110');insert into user07(id,name,adddate) values(1,'steven','2018110111');insert into user07(id,name,adddate) values(1,'steven','2018110112');insert into user07(id,name,adddate) values(1,'steven','2018110113');insert into user07(id,name,adddate) values(1,'steven','2018110114');insert into user07(id,name,adddate) values(1,'steven','2018110115');insert into user07(id,name,adddate) values(1,'steven','2018110116');insert into user07(id,name,adddate) values(1,'steven','2018110117');insert into user07(id,name,adddate) values(1,'steven','2018110118');insert into user07(id,name,adddate) values(1,'steven','2018110119');insert into user07(id,name,adddate) values(1,'steven','2018110120');insert into user07(id,name,adddate) values(1,'steven','2018110121');insert into user07(id,name,adddate) values(1,'steven','2018110122');insert into user07(id,name,adddate) values(1,'steven','2018110123');insert into user07(id,name,adddate) values(1,'steven','2018110200');insert into user07(id,name,adddate) values(1,'steven','2018110201');insert into user07(id,name,adddate) values(1,'steven','2018110202');insert into user07(id,name,adddate) values(1,'steven','2018110203');insert into user07(id,name,adddate) values(1,'steven','2018110204');insert into user07(id,name,adddate) values(1,'steven','2018110205');insert into user07(id,name,adddate) values(1,'steven','2018110206');insert into user07(id,name,adddate) values(1,'steven','2018110207');insert into user07(id,name,adddate) values(1,'steven','2018110208');insert into user07(id,name,adddate) values(1,'steven','2018110209');insert into user07(id,name,adddate) values(1,'steven','2018110210');insert into user07(id,name,adddate) values(1,'steven','2018110211');

执行两次，每条数据插入两份

七、验证数据

72条记录，按照时间先后顺序分布在36个分片中，验证完毕。

注意：rule.xml中配置的一天分成24份，一份是1小时，我们共36个分片，所以插入的数据只能限制在每月月初的36小时之内，如2018100100-2018100211
