创建测试库和表

[root@db01 conf]# mysql -S /data/3307/mysql.sock -e "create database taobao charset utf8;"
[root@db01 conf]# mysql -S /data/3308/mysql.sock -e "create database taobao charset utf8;"
[root@db01 conf]# mysql -S /data/3307/mysql.sock -e "use taobao;create table user(id int,name varchar(20))";
[root@db01 conf]# mysql -S /data/3308/mysql.sock -e "use taobao;create table order_t(id int,name varchar(20))";

重启mycat :

mycat restart
