PHP无法在Amazon EC2微实例上运行MYSQLI函数

呃,我的亚马逊微实例遇到了一些麻烦.我刚刚实现了 PHP< - > MYSQL界面.该实例似乎报告未安装MYSQLI插件,但是,所有其他指示都是相反的.我已经厌倦了对搜索的耐心,现在将吸引整个互联网的更高智慧.谢谢你的期待！

我的代码：

<?php
    error_reporting(E_ALL);
    ini_set('error_reporting',E_ALL);
    ini_set('display_errors','On');
    $mysql = mysqli_connect( 'localhost','EulerPhpUser','*********' );
    // more code

错误消息：致命错误：在第27行的/var/www/html/euler/login.php中调用未定义的函数mysqli_connect()

$cat /etc/*-release
Amazon Linux AMI release 2013.03

这是我的php.ini文件的一部分

; Maximum number of links.  -1 means no limit.
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.max-links
mysqli.max_links = -1

; Default port number for mysqli_connect().  If unset,mysqli_connect() will use
; the $MYSQL_TCP_PORT or the mysql-tcp entry in /etc/services or the
; compile-time value defined MYSQL_PORT (in that order).  Win32 will only look
; at MYSQL_PORT.
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.default-port
mysqli.default_port = 3306

; Default socket name for local MySQL connects.  If empty,uses the built-in
; MySQL defaults.
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.default-socket
mysqli.default_socket =

; Default host for mysql_connect() (doesn't apply in safe mode).
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.default-host
mysqli.default_host =

; Default user for mysql_connect() (doesn't apply in safe mode).
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.default-user
mysqli.default_user =

; Default password for mysqli_connect() (doesn't apply in safe mode).
; Note that this is generally a *bad* idea to store passwords in this file.
; *Any* user with PHP access can run 'echo get_cfg_var("mysqli.default_pw")
; and reveal this password!  And of course,any users with read access to this
; file will be able to reveal the password as well.
; http://www.php.net/manual/en/mysqli.configuration.php#ini.mysqli.default-pw
mysqli.default_pw =

; Allow or prevent reconnect
mysqli.reconnect = Off

这是phpifo()的唯一部分,我搜索mysqli产生了结果

最后,还有一点需要注意.我试图运行以下代码,服务器返回一个完全空白的页面.没有错误,没有任何错误.好像php崩溃而没有产生错误.我不确定如何解释.

if (function_exists('mysqli_connect')) {
     echo 'mysqli is installed';
}

我甚至非常沮丧,我尝试了一些PDO,但后来得到错误连接失败：找不到驱动程序

如果有任何进一步的信息请告知我们,我会及时提供.感谢您的帮助
