引子：
今天为论坛进行服务器空间的转移~~~先顺利将Mysql数据库用phpmyadmin导出~~
然后在新服务器上建好数据库后，然后进行导入！可是因为MySQL数据库的.sql文件大于2MB。所以在导入时就提示说超过2048KB的错误，不让导入….于是就引出了此文的解决办法，呵呵
解决办法：
1、打开php.ini。找到 upload_max_filesize 、 memory_limit 、 post_max_size 这三个参数！
(在默认的情况下,php只允许最大的上传数据为2M,也就是2048KB,而极限的最大使用内存memory_limit也仅为128M，Post的最大也为2M)
2、按您的服务器的实际性能配置进行如下改动：（注意：以下是按我的服务器性能和硬件配置进行的更改..）
upload_max_filesize = 8M (上传最大极限设定为8M,这个应该足够一般的文件WEB上传了)
memory_limit = 512M (因为服务器的内存为2GB,所以这里加到512M不过份吧，呵)
post_max_size = 8M (Post数据最大也设置为8MB,这个跟upload_max一样)
3、改完之后，我重新启动系统，再重新执行导入命令后：
Import has been successfully finished, 399 queries executed.
(显示导入成功,有多少个请求处理成功…)
（备注：改完后当你在到phpMyadmin的导入命令行时，虽然(有时候可能会仍然显示为:最大限制:2048KB/Max: 2,048KiB);但实际上你已经可以导入不超过8M的MySQL数据库.sql导出的备份文件了! 另，改完php.ini后，别忘了重启一下web服务或者是服务器哟！重启后升效!）
就此记录，希望对遇到同样问题的朋友有所帮助~
