client_max_body_size 1024M
upload_limit_rate 158k
如下：
location /upload {
upload_pass /up.php;
upload_cleanup 400 404 499 500-505;
#upload_store /data/app/test.local/upload_tmp;
upload_store /tmp;
upload_store_access user:r;
client_max_body_size 1024M;
upload_limit_rate 158k;
upload_set_form_field "${upload_field_name}_name" $upload_file_name;
upload_set_form_field "${upload_field_name}_content_type" $upload_content_type;
upload_set_form_field "${upload_field_name}_path" $upload_tmp_path;
upload_aggregate_form_field "${upload_field_name}_md5" $upload_file_md5;
upload_aggregate_form_field "${upload_field_name}_size" $upload_file_size;
upload_pass_form_field "^.*$";
#upload_pass_form_field "^pid$|^tags$|^categoryid$|^title$|^userid$|^user_id$|^is_original$|^upload_file_name$|^upload_file_content_type$|^upload_file_path$|^upload_file_md5$|^upload_file_size$";
}
２、修改php.ini
upload_max_filesize = 8M post_max_size = 10M memory_limit = 20M max_execution_time=300 file_uploads = On #默认允许HTTP文件上传，此选项不能设置为OFF。 upload_tmp_dir =/tmp/www
在上传大文件时，你会有上传速度慢的感觉，当超过一定的时间，会报脚本执行超过30秒的错误，这是因为在php.ini配置文件中 max_execution_time配置选项在作怪，其表示每个脚本最大允许执行时间(秒)，0 表示没有限制。你可以适当调整max_execution_time的值，不推荐设定为0。
