创建测试库和表（db01）

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

查看效果

[root@db01 conf]# mycat restart
[root@db01 conf]# mysql -uroot -p123456 -h 127.0.0.1 -P 8066
mysql> use TESTDB
mysql> show tables;
