自定义mime配置导致Cloud Foundry PHP网站实例崩溃
[英]Cloud Foundry PHP website instance crashes with custom mime configuration
问题描述
我正尝试在Cloud Foundry（更确切地说是Swisscom Application Cloud）部署带有html扩展名的基本php页面。
这是我唯一的源文件，位于${APP_ROOT}/www/index.html
<html>
<?php
phpinfo();
?>
</html>
我的配置文件如下。
在.bp-config/options.json ：
{
"WEBDIR": "www",
"PHP_VERSION": "{PHP_56_LATEST}",
"WEB_SERVER": "httpd"
}
在.bp-config/httpd/httpd.conf ：
ServerRoot "${HOME}/httpd"
Listen ${PORT}
ServerAdmin "${HTTPD_SERVER_ADMIN}"
ServerName sample-app.scapp.io
DocumentRoot "${HOME}/#{WEBDIR}"
Include conf/extra/httpd-modules.conf
Include conf/extra/httpd-mime.conf
我从Swisscom App Cloud中的设置获取的服务器名称：
在.bp-config/httpd/extra/httpd-modules.conf ：
LoadModule mpm_event_module modules/mod_mpm_event.so
根据错误日志，这似乎是必需的（如果未包括在内）。
在.bp-config/httpd/extra/httpd-mime.conf ：
<IfModule mime_module>
AddType application/x-httpd-php .php .htm .html
</IfModule>
为了方便起见，可以在此GitHub存储库中访问上面的源代码。
该实例无法启动，但是我找不到任何描述性的错误消息。 这些是Swisscom应用程序云的日志：

我想肯定还有其他日志，其中包含有关崩溃的更多信息，但我不知道在哪里可以找到它们。
是什么原因导致当机，我该如何解决？

我不确定您的应用为何会失败。 我的猜测是HTTPD不喜欢该配置，并且正在退出。 日志中没有HTTPD的输出，您应该看到它正在启动，就像这样。
例如：
2017-05-20T08:26:18.76-0400 [APP/PROC/WEB/0] OUT 12:26:18 httpd | [Sat May 20 12:26:18.741822 2017] [mpm_event:notice] [pid 103:tid 140440543442816] AH00489: Apache/2.4.25 (Unix) configured -- resuming normal operations
2017-05-20T08:26:18.77-0400 [APP/PROC/WEB/0] OUT 12:26:18 httpd | [Sat May 20 12:26:18.741947 2017] [mpm_event:info] [pid 103:tid 140440543442816] AH00490: Server built: Dec 20 2016 22:27:46
2017-05-20T08:26:18.77-0400 [APP/PROC/WEB/0] OUT 12:26:18 httpd | [Sat May 20 12:26:18.741961 2017] [core:notice] [pid 103:tid 140440543442816] AH00094: Command line: '/app/httpd/bin/httpd -f /home/vcap/app/httpd/conf/httpd.conf -D FOREGROUND'
如果要让PHP-FPM处理HTML文件，则需要进行一些更改。
1.）在.bp-config/httpd/extra/httpd-php.conf ，您需要修改或附加<Directory "${HOME}/#{WEBDIR}">块，以便将.html文件发送到PHP-FPM。 如果您不这样做，HTTPD只会为它们提供服务或返回404。
例如：同时发送.php和.html
<Directory "${HOME}/#{WEBDIR}">
<Files *.php>
<If "-f %{REQUEST_FILENAME}"> # make sure the file exists so that if not, Apache will show its 404 page and not FPM
SetHandler proxy:fcgi://#{PHP_FPM_LISTEN}
</If>
</Files>
<Files *.html>
<If "-f %{REQUEST_FILENAME}"> # make sure the file exists so that if not, Apache will show its 404 page and not FPM
SetHandler proxy:fcgi://#{PHP_FPM_LISTEN}
</If>
</Files>
</Directory>
2.）您需要指示PHP-FPM处理扩展名为.html文件。 默认情况下，它不是默认值，因为它试图防止由于配置错误而导致滥用（例如，防止攻击者评估带有意外扩展名的文件）。
为此，您需要添加文件.bp-config/php/fpm.d/php-process-html.conf （ php-process-html部分无关紧要，但名称必须以.conf结尾）。 在其中，您需要放置以下内容：
[www]
security.limit_extensions = .php .html
这告诉PHP-FPM处理.php和.html文件。
注意：这至少需要PHP构建软件包的v4.3.32，在撰写本文时，这是一个相当新的东西。 如果您使用的是旧版本的构建包，仍然可以，但是您需要提供一个完整的自定义php-fpm.conf配置文件，而不是仅覆盖此属性，该文件将放在.bp-config/php/php-fpm.conf 。 从这里获取一个php-fpm.conf文件，如果您仍然使用较旧的构建包，则可以将其用作入门的基础。
