上传文件时禁止 Apache 403
当我提交带有输入文件的 multipart/form-data 表单时，我遇到了一个奇怪的 apache 错误.似乎只有当我上传 70kb 或更大的文件时才会发生这种情况.
I'm having a strange apache error when I submit a multipart/form-data form with an input file. It seems that only happens when I upload files 70kb or bigger.
这是我的 php.ini 设置:
Here are my php.ini settings:
file_uploads = On
upload_max_filesize = 10M
max_execution_time = 90
max_input_time = 90
memory_limit = 196M
post_max_size = 10M
这是 test.php 中的 HTML:
Here is the HTML in test.php:
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="pdfMagazine" />
<input type="submit" value="Save" name="saveMagazine" />
</form>
这是错误:
Forbidden
You don't have permission to access /test.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache/2.2.24 (Unix) mod_ssl/2.2.24 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 Server at myserver.com Port 80
以下是有关环境的更多详细信息:
Here's some more details about the environment:
- Apache 没有安装 mod_security，没有
.htaccess限制文件上传 - 仅记录存在 403 代码的点
- 我试过的test.php权限是755和644
- 如果没有上传文件，表单提交正常.
谁能帮帮我?
提前致谢.

看来服务器确实安装了 mod_security，这里是 apache 原始日志:
It appears that server does have mod_security installed, here is apache raw log:
[Wed Jun 12 19:48:01 2013] [error] [client x.x.x.x] mod_security: Access denied with code 403. read_post_payload: Failed to create file "/root/tmp/20130612-194801-190.115.8.74-request_body-deJpho" because 13("Permission denied") [severity "EMERGENCY"] [hostname "myserver.com"] [uri "/test.php"]
[Wed Jun 12 19:48:01 2013] [error] [client x.x.x.x] mod_security: sec_filter_in: Failed to open file "/root/tmp/20130612-194801-190.115.8.74-request_body-deJpho" [hostname "myserver.com"] [uri "/403.shtml"]
做研究我发现了这个:
**Upload tmpdir issues**
Seeing this?
<source lang='php'> [Fri Nov 18 14:49:50 2011] [error] [client 72.52.142.215] mod_security: Access denied with code 406. read_post_payload: Failed to create file "/root/tmp/20111118-144950-72.52.142.215-request_body-xGPNPd" because 13("Permission denied") [severity "EMERGENCY"] [hostname "lakedonpedro.org"] [uri "/wp-cron.php?doing_wp_cron"] [unique_id "TsbhJkg0jtcAACYIFDk"] </source>
This actually happens because PHP's being set to use /root/tmp and the upload tmp dir. Let's set a few things then! Yay!
Make sure these are all set in /usr/local/lib/php.ini (session.save_path will probably already be set)
upload_tmp_dir = /tmp
session.save_path = /tmp
Make sure these are all set in /usr/local/apache/conf/modsec2.user.conf (or the applicable file for your system)
SecUploadDir /tmp
SecTmpDir /tmp
Restart the apachies.
It also seems it has worked adding the above to modsec.conf corrects this issue. per ~awilson
我确实更改了 php.ini，但 modsec 配置文件有一个很大的警告，只有服务器提供商可以编辑它，所以我正在联系他们.
I did change the php.ini but the modsec configuration file has a big warning that only servers provider can edit it so I'm contacting them.
我会让你知道发生了什么.
I'll let you know what happend.
[已解决]
Apaches 模块 mod_security 默认有 60kb 的上传限制，所以任何更大的上传都会抛出 403 错误代码.
Apaches module mod_security has a 60kb upload limit by default so any bigger upload will throw a 403 error code.
由于 modsec.conf 只能由服务器提供商编辑，我将以下行添加到每个根 .htaccess:
As the modsec.conf is only editable by the server provider, I add the following line to every root .htaccess:
SecFilterEngine Off
这通常会关闭 mod_security 过滤器.
That turned off the mod_security filter in general.
