Fixing PHP on Old Ubuntus

Note: This process has been superceded and entirely automated by the installer and this no longer has to be done by hand.

PHP 5 is currently limited to a maximum of 2 Gbyte file uploads, even on 64-bit systems. Fortunately this is easily fixed.

These instructions are for Ubuntu 12 and earlier only.

    At this point, it will state "Build complete" but complain about an error. Don't worry about this, the build has still worked. If you wish to test the build, run the command "cd fpm-build && make test; cd .." and it should pass the tests (except #39863). Then:
    cd apache2-build/.libs
    mv /usr/lib/apache2/modules/ /usr/lib/apache2/modules/
    cp /usr/lib/apache2/modules/
