我看了一些教程，目的是故意从源代码安装过时的apache版本以及它的依赖项。我遇到的问题是源于PHP没有被处理，如果我创建任何PHP文件，即使我已经安装了PHP-fpm，也会显示原始明文。
首先，使用以下代码配置、构建和编译Apache及其依赖项：

./configure --enable-so --with-mpm=event --with-included-apr --prefix=/usr/local/apache2

这是一个成功，但我一直觉得它遗漏了一些模块。这导致我从源代码（版本7.2.34）构建和编译PHP，以为这样可以解决原始文本和编译错误的问题。我使用以下命令配置：

./configure --with-sqlanywhere --with- apxs=usr/local/apache2/bin/apxs

我也做了一点研究，在这里的问题可能是什么。我注意到我没有mods启用文件夹，但已向前迈进。
我在httpd.conf文件中添加了以下内容

LoadModule php7_module modules/libphp7.so

在conf.modules.d/00-mpm.conf和conf.modules.d/01-cgi.conf中，我只有一个未注解的MPM模块

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

最后，这里是我的httpd.conf的一个副本

# 

# This is the main Apache HTTP server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.

# In particular, see

# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

# for a discussion of each configuration directive.

# 

# Do NOT simply read the instructions in here without understanding

# what they do.  They're here only as hints or reminders.  If you are unsure

# consult the online docs. You have been warned.

# 

# Configuration and logfile names: If the filenames you specify for many

# of the server's control files begin with "/" (or "drive:/" for Win32), the

# server will use that explicit path.  If the filenames do *not* begin

# with "/", the value of ServerRoot is prepended -- so "logs/access_log"

# with ServerRoot set to "/usr/local/apache2" will be interpreted by the

# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"

# will be interpreted as '/logs/access_log'.

# 

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

# 

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to specify a local disk on the

# Mutex directive, if file-based mutexes are used.  If you wish to share the

# same ServerRoot for multiple httpd daemons, you will need to change at

# least PidFile.

# 

ServerRoot "/usr/local/apache2"

# 

# Mutex: Allows you to set the mutex mechanism and mutex file directory

# for individual mutexes, or change the global defaults

# 

# Uncomment and change the directory if mutexes are file-based and the default

# mutex file directory is not on a local disk or is not appropriate for some

# other reason.

# 

# Mutex default:logs

# 

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

# 

# Change this to Listen on specific IP addresses as shown below to

# prevent Apache from glomming onto all bound IP addresses.

# 

# Listen 12.34.56.78:80

Listen *:80

# 

# Dynamic Shared Object (DSO) Support

# 

# To be able to use the functionality of a module that was built as a DSO you

# have to place corresponding `LoadModule' lines at this location so the

# directives contained in it are actually available _before_ they are used.

# Statically compiled modules (those listed by `httpd -l') do not need

# to be loaded here.

# 'Main' server configuration
