create database testdb07;
create database testdb08;
create database testdb09;
create database testdb10;
create database testdb11;
create database testdb12;
node2

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 Daemon

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 mycatdb
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> 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','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','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','2018110211');
执行两次，每条数据插入两份

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
分享题目：MyCat分库分表--实战09--按单月小时
