一、准备阶段

1、建表语句

create table student(id integer not null primary key,"cf"."name" varchar,"cf"."age" integer,"cf"."address" varchar);

2、数据准备

说明：这里准备600条测试数据

3、将student01.csv数据放入本地/home/test目录下

二、导入方式一

1、先手动建表

create table student(id integer not null primary key,"cf"."name" varchar,"cf"."age" integer,"cf"."address" varchar);

2、命令

[root@master bin]# ./psql.py -t STUDENT master,slaves1,slaves2:2181 /home/test/student01.csv

3、效果

三、导入方式二

1、在/home/test/下创建创建表的aa.sql文件

create table stu(id integer not null primary key,"cf"."name" varchar,"cf"."age" integer,"cf"."address" varchar);

2、命令

[root@master bin]# ./psql.py -t STU 192.168.230.21 /home/test/aa.sql /home/test/student01.csv

注意：当数据的文件名为stu.csv时，不用指定-t STU参数；因为如果在不指定-t参数的情况下，会默认把.csv的文件名当作表明；
