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、创建测试数据
node1
create database testdb1;
create table testdb1.t01(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb1.t01 values(@@hostname,@@hostname,@@hostname);
create database testdb2;
create table testdb2.t02(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb2.t02 values(@@hostname,@@hostname,@@hostname);
create database testdb3;
create table testdb3.t03(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb3.t03 values(@@hostname,@@hostname,@@hostname);
node2
create database testdb4;
create table testdb4.t04(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb4.t04 values(@@hostname,@@hostname,@@hostname);
create database testdb5;
create table testdb5.t05(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb5.t05 values(@@hostname,@@hostname,@@hostname);
create database testdb6;
create table testdb6.t06(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb6.t06 values(@@hostname,@@hostname,@@hostname);
node3
create database testdb7;
create table testdb7.t07(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb7.t07 values(@@hostname,@@hostname,@@hostname);
create database testdb8;
create table testdb8.t08(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb8.t08 values(@@hostname,@@hostname,@@hostname);
create database testdb9;
create table testdb9.t09(name1 varchar(40),name2 varchar(40),name3 varchar(40));
insert into testdb9.t09 values(@@hostname,@@hostname,@@hostname);
二、配置schema.xml
select user()
select user()
select user()
三、配置server.xml
mysql
mycatdb1,mycatdb2,mycatdb3,mycatdb4,mycatdb5,mycatdb6,mycatdb7,mycatdb8,mycatdb9
四、启动mycat
/usr/local/mycat/bin/mycat start
查看mycat日志

五、访问8066端口查看数据
[root@mycat conf]# mysql -uroot -pmysql -P8066 -h292.168.8.30 -e "select * from mycatdb1.t01"
