需要有关可能与 Zend 相关的 PHP Web 应用程序引导错误的帮助

问题描述 投票：0回答：2

我正在尝试让一个名为 OpenFISMA 的程序在 AWS 中的 Ubuntu AMI 上运行。该应用程序并不是在 Ubuntu 平台上真正编码的，但我在我的舒适区中，并尝试了 CentOS 和 OpenSUSE（两者都是该应用程序的“原生”），以获得相同或更差的结果。那么，为什么不让它在 Ubuntu 上运行呢？无论如何，该应用程序可以在这里找到：www.openfisma.org，并且可以在这里找到安装指南：https://openfisma.atlassian.net/wiki/display/030100/Installation+Guide安装指南有点糟糕。它没有以任何连贯的方式列出依赖关系，也没有提供任何细节（甚至没有在整个页面上提到一次 Zend），因此我做了很多工作来推测我所拥有的信息。此页面提供了一些依赖项信息（不过，Zend 一次也没有被提及）： https://openfisma.atlassian.net/wiki/display/PUBLIC/RPM+Management#RPMManagement-BasicOverviewofRPMPackages

无论如何，我完成了安装（到目前为止我可以重建它）。我将第一次进入登录页面，当我加载页面时应该会发生某种引导。 （我不是程序员，所以我不知道它在那里做什么。）无论如何，我在网页上收到一条消息：“引导应用程序时发生异常。”

所以，然后我去查看 /var/www/data/logs/php.log 并找到以下消息： 

[22-Oct-2013 17:29:18 UTC] PHP Fatal error:  Uncaught exception 'Zend_Exception' with message 'No entry is registered for key 'Zend_Log'' in /var/www/library/Zend/Registry.php:147
Stack trace:
#0 /var/www/public/index.php(188): Zend_Registry::get('Zend_Log')
#1 {main}
  thrown in /var/www/library/Zend/Registry.php on line 147

每次加载页面时都会发生这种情况。我发现存在与在 Zend 注册表中注册 Zend_Log 变量相关的问题，但除此之外我真的不知道该怎么办。我是否缺少它需要的包，或者该应用程序是否未编码以正确注册变量？我不知道。非常感谢任何帮助。下面包含日志消息 (index.php) 中引用的应用程序文件。

我最近在 CentOS 6.5 上遇到了这个问题。关闭 selinux 解决了这个问题。

要测试，您可以尝试：

# setenforce 0

显然关闭 selinux 会带来安全隐患，因此一旦您确认它有效，您可能需要考虑创建一个 selinux 策略以允许 apache 访问 openfisma 目录中的文件。

如何关闭selinux

我遇到了同样的问题，但找到了似乎有效的解决方案，并且允许 selinux 继续设置为强制执行。我运行了以下两个命令，我能够获得登录屏幕。

# semanage fcontext -a -t httpd_sys_rw_content_t "/usr/share/openfisma(/.*?)"

# restorecon -R -v /usr/share/openfisma/

根据我目前对 SELinux 的了解，这会在 /usr/share/openfisma 目录及其下面的任何内容的内容上设置 httpd 读写上下文。 Restorecon 将递归地重置该目录中所有文件的上下文。

编辑：我还发现需要以下命令

# /usr/sbin/setsebool -P httpd_can_network_connect on
