Instaltion failed, but all mysql and pdo are in my php.INI

Support & Bugs
1

Hello, just trying to install on my server and I receive the following issue.
PDO extension (Y)

Piwik requires either the mysqli extension or both the PDO and pdo_mysql extensions.

On a Windows server you can add the following lines to your php.ini:

extension=php_mysqli.dll
extension=php_pdo.dll
extension=php_pdo_mysql.dll

More information on: PHP PDO and MYSQLI.

However the green check is shown, but no option to proceed.

My Ini File has these uncommitted:

extension=php_mssql.dll
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_openssl.dll
[…]
extension=php_pdf.dll
extension=php_pdo.dll
extension=php_pdo_mssql.dll
extension=php_pdo_mysql.dll

I just spent 4 hours trying to figure out why Piwik can’t see the modules that get_loaded_extensions reports are there. This is the kind of error that should be in the installation docs in huge red letters. You guys almost lost a Windows devotee here!

Sorry. This was fixed after we released. It is however the first sticky post in the support forum.

Hi,

I’ve got exactly the same problem (using windows).
I’m using apache http server 2.4.6 and php 5.5.4.
My configuration should be okay since <?php phpinfo(); ?> in my index.php works.

I removed the comment signs in my php.ini so the extensions should be loaded:
…
extension=php_mysqli.dll
…
extension=php_pdo_mysql.dll

I’ve tested it with php 5.4.20 in combination with apache hhtp server 2.2 too - same result… :frowning:

Can someone help me please?

Okay, problem solved…
According to the error.log php could not find the extensions - setting an absolute path (extension_dir) instead of the relative one (“res”) solved the problem. So it wasn’t a piwik problem, but a php problem (my first impression of php is not very good: outdated documentation etc… very annoying, it took me 5 hours to solve this…)
