PHP still won't allow file uploads larger than

问题:

I have a Debian Squeeze install on an Amazon EC2 instance running Apache2, and PHP 5.3.3-7. I would like it to be able to accept uploads from a standard point-and-shoot camera (about 5 MB). Accordingly, I've edited php.ini in /etc/php5/apache2/ to allow for up to 18MB uploads, and I've upped the time PHP will allow to work on a script.

Despite restarting Apache and even the machine itself, it absolutely refuses to upload any file larger than 2 MB. Is this an EC2 problem or is it still a PHP issue. I'm fairly sure I've ironed out all possibility of it being PHP, but I've been staring at the same 4 lines of code for the last week and searching like a mad person for what this could possibly be.

/etc/php5/apache2/php.ini:

max_execution_time = 120
...
max_input_time = 120
...
upload_max_filesize = 18M
...
post_max_size = 18M

I have double checked just now with phpinfo(), these settings are in effect, but it still does not work.

回答1:

Check settings upload_max_filesize and post_max_size in your php.ini file

The problem is likely to be Sohusin. The default packages from APT on debian has Sohusin built in.

This also affects your upload size limit. Take a look at this link for a fix and an explanation: http://www.cyberciti.biz/faq/linux-unix-apache-increase-php-upload-limit/

don't know if that will be of any help on your setup?

In Apache:

TimeOut

Amount of time the server will wait for certain events before failing a request

LimitRequestBody

Restricts the total size of the HTTP request body sent from the client

Also on some server setups you cant change php.inp via scipts
