php mysqli:配置问题

I am currently running an Apache 2.4 server with PHP 5.5.1, and it is connected to Django via mod_wsgi (in case that matters). This is all running on Oracle Linux. In this set-up, I am trying to use mysqli and the method mysqli_connect. However, I am facing issues with my mysqli set-up. I have used the following website: MySQLi Setup. However, even after running ./configure --with-mysqli=/usr/bin/mysqlconfig and ./configure --with-mysqli, I still do not see a mysqli section in my phpinfo() test site. I have run make and make install after both and it has worked fine.

Furthermore, when I try the following command ./configure --with-mysql=/usr/bin/mysql_config --with-mysqli=mysqlnd, I get the following error: configure: error: Cannot find MySQL header files under /usr/bin/mysql_config. Note that the MySQL client library is not bundled anymore!

On top of this, I have uncommented the extension=php_mysqli.dll line.

Right now, I have an idea of what I need to do, which is to get ahold of the MySQL client library and allow access to it by php. However, I am unsure of how to do this, and many of the questions + answers I have found have not worked.

Any help is appreciated. Thanks.
