CentOS 7 PHP 7.2.3 Apache 2.4: Apache is running a threaded MPM, but your PHP Module is not compiled to be threadsafe. You need to recompile PHP – PHP Versions

I have followed a few tutorials in order to purposely install an outdated version of apache from the source as well as its dependencies. The issue I am experiencing is stemming from PHP not being processed and showing raw plaintext if I created any PHP file even though I’ve installed PHP-fpm.

First, configured, built, and compiled apache and its dependencies accordingly using this:

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

That was a success but I keep feeling like it left out some modules for some reason. This led me to build and compile PHP from the source (version 7.2.34) under the impression that it would solve the issue of raw text and compilation errors. I configured using the following command:

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

I’ve also done a bit of research on here as to what the issue could be. I’ve noticed I have no mods-enabled folder but have moved onward.

I’ve added the following to my httpd.conf file

LoadModule php7_module modules/libphp7.so 

I only have one MPM module uncommented in conf.modules.d/00-mpm.conf AND conf.modules.d/01-cgi.conf

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so

Lastly, here’s a copy of my httpd.conf

#
# 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.
