创建数据表
<span style="font-size:18px;">CREATE TABLE weblogs(
            md5  varchar(32),
            url varchar(64),
            request_date date,
            request_time time,
            ip varchar(15))
</span>

我的版本是：Server version: 5.5.38-0ubuntu0.12.04.1-log (Ubuntu)


在使用如下命令导入时会报错：

<span style="font-size:18px;">mysql> LOAD  DATA LOCAL INFILE '/home/hadoop/weblog_entries.txt' INTO table weblogs FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n';
ERROR 1148 (42000): The used command is not allowed with this MySQL version
</span>


提示这个版本的mysql不支持这样导入


解决办法：http://dev.mysql.com/doc/refman/5.5/en/load-data-local.html

<span style="font-size:18px;">hadoop@caozw:~$ mysql -uroot<span style="background-color: rgb(255, 0, 0);"> --local-infile=1</span>  -p
Enter password:

You can turn off this feature to get a quicker startup with -A

Database changed
mysql> <span style="color:#FF0000;">LOAD  DATA LOCAL INFILE '/home/hadoop/weblog_entries.txt' INTO table weblogs FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'</span>;

在连接mysql的时候加上--local-infile的参数 然后导入即可


或者使用如下方式：



<span style="font-size:18px;">mysql -u [youruser] -h [youraddress] -p [yourpassword] [yourdatabase] --local-infile=1 -e "[yourcmd]" </span>


<span style="font-size:18px;">mysql -uroot -p123456 realworld --local-infile=1 -e "LOAD DATA local INFILE '/home/hadoop/weblog_entries.txt' INTO table weblogs FIELDS TERMINATED BY '\t' LINES TERMINATED BY '\n'"</span>

原因分析：根据官方的解释是mysql在编译的时候默认把local-infile的参数设为0，就是关闭了从本地load的功能，所以如果需要使用只能自己打开 通过链接的时候把该参数设置为1的方式



另外windows下面的换行符和linux的是不一样的

windows换行是\r\n，十六进制数值是：0D0A。
LINUX换行是\n，十六进制数值是：0A
