因为ubuntu默认自带的mysql版本为5.5,并不能使用load data infile这种高级的功能，因此我们写了一个通用的脚本来上传文件

shell脚本

?

cat ./employee.csv | while read LINE                                                                             
do                                                                                                               
        eva l $( echo $LINE | awk -F ',' '{print "ds="$1 ";id="$2 ";name="$3}' )                                  
        echo ds=$ds id=$id name=$name                                                                            
        mysql -uroot -p655453 test --default-character-set=utf8 -e  "replace into wechat_employee values('$ds','$id','$name')"
done

要导入数据到Mysql最重要的一点就是要三码合一，即client和server的编码还有表的编码要一致，server的编码可以在/etc/mysql找一下配置文件修改，客户端的编码在insert之前可以设置一下，可以忽略
