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
partbymonth
yyyy-MM-dd
2016-01-01
四、启动mycat
/usr/local/mycat/bin/mycat start
查看mycat日志
STATUS | wrapper | 2018/11/22 19:52:42 | --> Wrapper Started as Daemon
STATUS | wrapper | 2018/11/22 19:52:42 | Launching a JVM...
INFO | jvm 1 | 2018/11/22 19:52:42 | OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=64M; support was removed in 8.0

INFO | jvm 1 | 2018/11/22 19:52:49 | MyCAT Server startup successfully. see logs in logs/mycat.log
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 (0.03 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 |
+-------------------+
3 rows in set (0.01 sec)
mysql> select * from user06;
ERROR 1105 (HY000): Table 'testdb36.user06' doesn't exist
mysql> drop table if exists user06;
Query OK, 0 rows affected, 1 warning (0.38 sec)
mysql> create table user06(
-> id int not null auto_increment,
-> name varchar(64),
-> adddate datetime,
-> primary key(id)
-> );
Query OK, 0 rows affected (1.73 sec)
六、插入测试数据
insert into user06(id,name,adddate) values(1,'steven','2016-05-09 12:32:12');
insert into user06(id,name,adddate) values(2,'steven','2016-09-09 12:32:12');
insert into user06(id,name,adddate) values(3,'steven','2016-12-09 12:32:12');
insert into user06(id,name,adddate) values(4,'steven','2017-05-09 12:32:12');
insert into user06(id,name,adddate) values(5,'steven','2017-06-09 12:32:12');
insert into user06(id,name,adddate) values(6,'steven','2017-07-09 12:32:12');
insert into user06(id,name,adddate) values(7,'steven','2018-05-09 12:32:12');
insert into user06(id,name,adddate) values(8,'steven','2018-05-09 12:32:12');
insert into user06(id,name,adddate) values(9,'steven','2018-08-09 12:32:12');
insert into user06(id,name,adddate) values(10,'steven','2018-12-09 12:32:12');
七、验证数据
