将 PHP 从 5.3.3 升级到 5.4.40 会出现问题

Question

我有一台正在运行的 RHEL 6.7 服务器：Apache：2.2.15 PHP 5.3.3 getenforce => 已禁用

就目前而言，它运行良好。服务器的网站管理员告诉我，PHP-5.3 将不再适用于 Facebook 的 API，我需要升级到 5.4 或更高版本。为了做到这一点，我按照以下步骤操作http://developerblog.redhat.com/2013...6-using-rhscl/ 我唯一真正做的改变是：'rhn-channel --add --channel=rhel-x86_64-server-6-rhscl-1'，因为这篇文章有点过时了。除此之外，我严格遵循了步骤。我甚至得到了

"[warn] module php5_module is already loaded, skipping"

为了解决这个问题，我执行了“mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf.php5.3”以防止它在 Apache 启动时运行。然后我重新启动了 Apache。这是我在错误日志中得到的内容。

'httpd -M | grep php' 显示：

Syntax OK
  php5_module (shared)

当我尝试加载网页而不是像以前一样执行 index.php 时，我得到的只是一个空白页。我想我错过了一些简单的东西。下面是我当前的 /etc/httpd/conf.d/php54-php.conf

有人知道我该如何让它正确运行 index.php 吗？非常感谢您抽出时间。
