1、问题
最近在开发网盘系统的时候发现,上传大文件时会提示IO Error #2038 的错误。系统采用了PHP和Flash控件来上传文件,网上的资料表明出现此错误的可能原因包括:
URL无效
上传文件大小超过服务器最大上传限制或最大POST限制
与服务器连接异常中断
上传的文件为空
文件(夹)权限
2、解决方法
首先排除了3、4和5的原因,而在上传小文件的时候是正常的,也可以排除1的原因。故此集中在第2项进行解决,可能的原因包括:
限制了上传文件类型
max_input_time超时
upload_max_filesize上传文件限制
在php.ini
中分别对max_execution_time
、max_input_time
、memory_limit
、post_max_size
、upload_max_filesize
等五个参数进行了设置(可参考php.ini修改php上传文件大小限制),调大了参数值,发现在上传小于设置的参数值大小的文件时,仍然存在报错的情况。
由于使用的是Nginx服务器,此文描述的情况与本文的情况类似,于是在Nginx站点配置文件中加入了client_max_body_size
参数的设置:
client_max_body_size 1000m;
重启Nginx服务器后,问题解决。
3、总结
在用浏览器上传超大文件时,需要同时修改Nginx和PHP的参数设置,包括:
Nginx:
client_max_body_size
PHP:
max_execution_time
、max_input_time
、memory_limit
、post_max_size
、upload_max_filesize
