2024-03-23 19:53:52

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

123456789101112 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

123456789101112 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

123456789101112 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

12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667 <?xml version="1.0"?><!DOCTYPE mycat:schema SYSTEM "schema.dtd"><mycat:schema xmlns:mycat=" <schema name="mycatdb" checkSQLschema="false" sqlMaxLimit="100"> <table name="user07" dataNode="dn$1-36" rule="sharding-by-hour-adddate"></table> </schema>  <dataNode name="dn1" dataHost="node1" database="testdb01" /> <dataNode name="dn2" dataHost="node1" database="testdb02" /> <dataNode name="dn3" dataHost="node1" database="testdb03" /> <dataNode name="dn4" dataHost="node1" database="testdb04" /> <dataNode name="dn5" dataHost="node1" database="testdb05" /> <dataNode name="dn6" dataHost="node1" database="testdb06" /> <dataNode name="dn7" dataHost="node1" database="testdb07" /> <dataNode name="dn8" dataHost="node1" database="testdb08" /> <dataNode name="dn9" dataHost="node1" database="testdb09" /> <dataNode name="dn10" dataHost="node1" database="testdb10" /> <dataNode name="dn11" dataHost="node1" database="testdb11" /> <dataNode name="dn12" dataHost="node1" database="testdb12" /> <dataNode name="dn13" dataHost="node2" database="testdb13" /> <dataNode name="dn14" dataHost="node2" database="testdb14" /> <dataNode name="dn15" dataHost="node2" database="testdb15" /> <dataNode name="dn16" dataHost="node2" database="testdb16" /> <dataNode name="dn17" dataHost="node2" database="testdb17" /> <dataNode name="dn18" dataHost="node2" database="testdb18" /> <dataNode name="dn19" dataHost="node2" database="testdb19" /> <dataNode name="dn20" dataHost="node2" database="testdb20" /> <dataNode name="dn21" dataHost="node2" database="testdb21" /> <dataNode name="dn22" dataHost="node2" database="testdb22" /> <dataNode name="dn23" dataHost="node2" database="testdb23" /> <dataNode name="dn24" dataHost="node2" database="testdb24" /> <dataNode name="dn25" dataHost="node3" database="testdb25" /> <dataNode name="dn26" dataHost="node3" database="testdb26" /> <dataNode name="dn27" dataHost="node3" database="testdb27" /> <dataNode name="dn28" dataHost="node3" database="testdb28" /> <dataNode name="dn29" dataHost="node3" database="testdb29" /> <dataNode name="dn30" dataHost="node3" database="testdb30" /> <dataNode name="dn31" dataHost="node3" database="testdb31" /> <dataNode name="dn32" dataHost="node3" database="testdb32" /> <dataNode name="dn33" dataHost="node3" database="testdb33" /> <dataNode name="dn34" dataHost="node3" database="testdb34" /> <dataNode name="dn35" dataHost="node3" database="testdb35" /> <dataNode name="dn36" dataHost="node3" database="testdb36" />  <dataHost name="node1" maxCon="1000" minCon="10" balance="1" writeType="0" dbType="mysql" dbDriver="native" switchType="1" slaveThreshold="100"> <heartbeat>select user()</heartbeat>  <writeHost host="192.168.8.31" url="192.168.8.31:3306" user="root" password="mysql"></writeHost> </dataHost> <dataHost name="node2" maxCon="1000" minCon="10" balance="1" writeType="0" dbType="mysql" dbDriver="native" switchType="1" slaveThreshold="100"> <heartbeat>select user()</heartbeat>  <writeHost host="192.168.8.32" url="192.168.8.32:3306" user="root" password="mysql"></writeHost> </dataHost> <dataHost name="node3" maxCon="1000" minCon="10" balance="1" writeType="0" dbType="mysql" dbDriver="native" switchType="1" slaveThreshold="100"> <heartbeat>select user()</heartbeat>  <writeHost host="192.168.8.33" url="192.168.8.33:3306" user="root" password="mysql"></writeHost> </dataHost></mycat:schema>

三、配置rule.xml

123456789 <tableRule name="sharding-by-hour-adddate"> <rule> <columns>adddate</columns> <algorithm>sharding-by-hour</algorithm> </rule> </tableRule> <function name="sharding-by-hour" class="io.mycat.route.function.LatestMonthPartion"> <property name="splitOneDay">24</property> </function>

<property name="splitOneDay">24</property>每天24份

四、启动mycat

1	`/usr/local/mycat/bin/mycat` `start`

查看mycat日志

1234567 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) INFO | jvm 1 | 2018/11/23 12:54:23 | Copyright 1999-2006 Tanuki Software, Inc.

五、登录MySQL查看逻辑表

1	`mysql -uroot -pmysql -P8066 -h192.168.8.30`

12345678910111213141516171819202122232425262728 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

123456789101112131415161718192021222324252627282930313233343536 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
