Drupal - MySQL support not included in PHP

Question

I am getting the following error on install of CiviCRM:

PHP Configuration

MySQL support MySQL support not included in PHP.

I am running:

CENTOS 6.8

Apache 2.4.18

Drupal 7.54

CiviCRM 4.7.16

PHP 5.5.35

MySQL 5.6.35

The following lines of php.ini are uncommented

extension=pdo.so

extension=pdo_sqlite.so

extension=pdo_mysql.so

I cannot quite figure out this error and so far have found nothing in my search that leads me to a solution.

Anyone have some insight?

TIA

Gary

Answer 1

CiviCRM is looking for the function mysqli_connect(), which is provided via the mysqli ("MySQL improved") extension in PHP.

To enable this, uncomment -

extension=mysqli.so

If that doesn't work, your next question may be: How to enable mysqli in PHP?
