It’s not an uncommon scenario for Apache to not play nicely with Rails when dealing with multipart forms and large uploaded files. There are a few solutions out there, but the best we have seen is modporter from the guys at ActionRails.
So, you’ll need a few things to beef up Apache; if you haven’t got them already:
sudo apt-get install libapache2-mod-apreq2 sudo apt-get install libapreq2-dev sudo apt-get install apache2-threaded-dev
Now fetch the latest ModPorter from github from here. Once you have downloaded and unpacked this, edit the Rakefile and change the apxs variable to apxs2, then type:
cd modporter-directory rake
And, you’ll probably want the modporter plugin for Rails to give you a nice consistent interface for uploaded files rather than differentiate String IOs and UploadedFile objects.
If you have git:
script/plugin install git://github.com/actionrails/modporter-plugin.git
Otherwise, download the tar from here, unpack and stick in your vendor/plugins directory.
Now configure Apache to use load some additional modules, edit your apache.conf file to include (your path to modules may be different):
LoadModule apreq_module modules/mod_apreq2.so LoadModule porter_module modules/mod_porter.so
