As user mtcs posted below, this one-liner will grab the necessary packages without grabbing non-Fedora/RedHat packages (which my previous instructions did, causing needless headaches):

Next, restart Apache / httpd to have PHP load the UploadProgress extension:

Finally, test by going to /admin/reports/status on your site to see if UploadProgress is reported to be working.

OpenVZ VPS / PHP 5.4.11

if you indeed use the latest PHP version from remi repository and install uploadprogress rpm you may end up with incompatible PHP/uploadprogress API versions. If you run a CentOS 6 openVZ VPS you should install first the relevant kernel headers from openvz.org, then install php-devel 5.4.11 and php-pear from remi repository, and finally build/install uploadprogress via pecl:


> yum --nogpgcheck localinstall vzkernel-headers-2.6.32-042stab065.3.x86_64.rpm
> yum install gcc-c++ php-devel php-pear
> pecl install uploadprogress
> echo "extension=uploadprogress.so" >> /etc/php.ini Read more

Note for SELinux users

To install on a Fedora-based distro (RHEL, CentOS, etc.) there are two main options:

• Install from the repository through a yum install drupal command.
• Install it yourself.

The installation instructions will vary a bit depending on your choice, as will the version you wind up with in some cases.

To be compliant with FHS guidelines on architecture independent system components (http://www.pathname.com/fhs/pub/fhs-2.3.html#THEUSRHIERARCHY) vs transient data placement (http://www.pathname.com/fhs/pub/fhs-2.3.html#THEVARHIERARCHY) and to enforce Fedora-ish system segregation Fedora and its derivatives place the code part of systems like Drupal and WikiMedia in /usr/share and the data elements (like files/ and images/) in /var/www. These parts are bound together through a series of symlinks, as the original development concept behind Drupal and other such systems did not take the FHS into account (there is a pretty big generation/culture gap between core Unix developers and web developers -- and embedding code to this extent inside of what used to be public data files (.html files becoming .php files and totally bypassing cgi-bin) was never thought of when the FHS was originally conceived). This can be confusing for newcomers.

PDO is an acronym for PHP Data Objects. PDO is a lean, consistent way to access databases. This means developers can write portable code much easier. PDO is not an abstraction layer like PearDB. PDO is a more like a data access layer which uses a unified API (Application Programming Interface).

How to enable PDO

To enable PDO, configure --enable-pdo and --with-pdo-sqlite --with-pdo-mysql or whatever database needs supporting by PDO (see the PHP manual for more information).

Windows users

• For Apache, you will need to make sure php_pdo.dll and php_pdo_mysql.dll exist in the php/ext directory, un-comment or add the appropriate lines in php.ini, and restart the web server.
• For IIS, PDO DLLs are not enabled by default. The preferred method for enabling them is to go to the Control Panel | Add/Remove Programs, highlight your PHP installation and click "Change" (Change/Remove - XP). Specify "FastCGI", then modify the installed extensions to include these two, then restart your server.
