How To Run 2 Versions Of PHP On The Same CentOS Server

Part of our moving to a mobile-oriented eCommerce platform and away from our former desktop orientation involved us upgrading from Drupal 6 to Drupal 7.

That, and the forces of time, technology and fashion! All of the technologies involved in our Drupal 6 eCommerce website were reaching (or had reached) their End Of Life (EOL) date. This meant that our business was relying on technologies that were no longer supported by their respective communities.

So, after resisting the inexorable forces of time for as long as possible, we recognized that the market had truly moved on and the inevitable had arrived.

It was time to upgrade. What a drag. I say this because we had 10 years of accumulated operating information on our "obsolete" Drupal 6 eCommerce website that we and our customers relied on constantly, and were loathe to abandon.

In terms of our Drupal 7 migration; while we had managed to help our customers keep their login username and email information, we had to force our customers to re-initialize their passwords because there is no way to migrate user passwords from Drupal 6 (MD5) to Drupal 7 (SHA512).

The last challenge for us in terms of moving customers from Drupal 6 to Drpual 7 was to somehow figure out a way to move customer order history from Drupal 6 to Drupal 7. This was being complicated by the fact that we had completely re-built our Drupal 7 eCommerce website from scratch, leaving the product (pid) values different between the two website databases, and the structure of the databases had changed between Drupal 6 (which used Ubercart 2) and Drupal 7 (which uses Ubercart 3). While the Drupal 6 database schema and the Drupal 7 database schema had not changed much, Ubercart database schema had, and that's where order data was being kept.

With the imminent retirement of our old server, and the migration of order history information getting complicate, it became critical to figure out a way to be able to run parallel versions of our website (old & new) on a single server, because the old server hosting the old website was being decommissioned.

Here's a quick analysis of our situation. The ideal solution seemed to be to figure out a way to be able to run both websites on the same server for a little while, so as to enable customer order history lookup...but with only the OLD website available to the Administrator!

...at least, until we figure out a way to migrate the customer order history across from Drupal 6 to Drupal 7 and then maybe we just turn the old website off - or keep it around just for its historical lookup potential.

Unfortunately, simply migrating the Drupal 6 database and website code over to the new server didn't work, because PHP has changed over time.

OLD:

- CentOS release 6.10 (Final)
- PHP 5.3.3 (cli) (built: Nov 1 2019 12:28:08)
- Apache/2.2.15 (Unix)
- mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86_64) using readline 5.1

- Obsolete, at EOL

- Holds all OLD client authentication information
- Holds all OLD client contact information
- Hold all OLD client order history
- On server soon to be de-commissioned
- Needed for internal reference purposes (some customers order only 1x per year)

NEW:

- CentOS Linux release 7.7.1908 (Core)
- A CUSTOM INSTALLED PHP 7.1.33 (cli) (built: Oct 25 2019 01:51:40) ( NTS )
- Server version: Apache/2.4.6 (CentOS)
- mysql Ver 5.5.64-MariaDB for Linux on x86_64 (MariaDB Server)

- Current, not at EOL (at least for a couple more years)

- Holds all OLD and NEW client authentication information (excepting passwords)
- Holds all OLD and NEW client contact information
- Holds all NEW client order history, but does NOT hold OLD client order history
- Cannot accept OLD server order history (product ID's are different)

The CUSTOM INSTALLED PHP 7.1.33 happened because I had to manually upgrade the PHP version on my new server to run more modern websites, so I upgraded it post-installation. CentOS 7 normally installs PHP 5.4, which simply wasn't modern enough for some of the websites I installed.

PHP is now a far more strict programming language than it was in the old days. Here's a sample of what happened when I tried to run our Drupal 6 eCommerce website (written against PHP 5) in a PHP 7 environment:

[Tue Nov 26 22:26:43.296914 2019] [php7:error] [pid 26555] [client 103.11.143.20:58276] PHP Fatal error: 'break' not in the 'loop' or 'switch' context in <drupal_root>/sites/all/modules/imageapi/imageapi_gd.module on line 335

[Tue Nov 26 22:31:29.445122 2019] [php7:error] [pid 26545] [client 14.0.153.23:25162] PHP Fatal error: Uncaught Error: Call to undefined function ereg() in <drupal_root>/includes/file.inc:1085\nStack trace:\n#0 /var/www/vhosts/holisticpethelp.com/legacy/content/includes/common.inc(2914): file_scan_directory('sites/all/modul...', '.theme.inc$', Array, 0, true, 'name', 0)\n#1 <drupal_root>/sites/all/modules/ctools/ctools.module(236): drupal_system_listing('.theme.inc$', 'sites/all/modul...', 'name', 0)\n#2 <drupal_root>/sites/all/modules/ctools/ctools.module(304): _ctools_passthrough(Array, 'theme')\n#3 <drupal_root>/includes/theme.inc(278): ctools_theme(Array, 'module', 'ctools', 'sites/all/modul...')\n#4 <drupal_root>/includes/theme.inc(433): _theme_process_registry(Array, 'ctools', 'module', 'ctools', 'sites/all/modul...')\n#5 <drupal_root>/includes/theme.inc(237): _theme_build_registry(Object(stdC in <drupal_root>/includes/file.inc on line 1085

Now, if I was feeling super brave, I could have hunted down each of these errors and fixed them one-by-one - and maybe in the end have gotten our Drupal 6 code running in a PHP 7 environment. But then, I would still have that Drupal 6 End Of Life issue to deal with:

So, while fixing Drupal 6 to run on a more modern version of PHP might look like an interesting and fun thing to do, it also looked like a lot of work that just led to a lot more work.

The real answer - at least to me - seemed to be to figure out how to upgrade to the most mature, stable and well-developed next version of Drupal that offered an "in system" upgrade path within the Drupal family of versions from that point thereafter. My final analysis was that Drupal 7 was the version that met all of these criteria, because it was the oldest, best developed (but still supported) version of Drupal available at the time.

Here's what drupal.org has to say about moving between major Drupal versions:

As part of the refocus to mobile, we also took the opportunity to completely audit and refresh our website in terms of product, descriptions, images and videos. We took the time to basically revamp our eCommerce presence from top to bottom. Our eCommerce presence became a LOT BETTER as a result of the scrutiny and focus.

We got the new mobile-centric eCommerce website was up and running in under a week, but we kept the old website running in parallel for over a month, because it was still the #1 website that our clients used, and we wanted to offer them as much continuity and time to transition comfortably as possible. Every day, they continued to post orders at the old website, and we didn't want to disrupt that.

The only things we changed were the following:

1) All of our advertisements directed new customers to the new website

2) We changed the JOIN button on our old website to re-direct to the new website.

With all of that in place, the next thing to do was to figure out How To Run Multiple PHP Versions On The Same CentOS 7 Web Server.

Add Functionality Via Specialized Repositories

Because Getting Multiple PHP Versions To Run On The Same CentOS 7 Web Server requires access to a set of specialized software repositories that may or may not be natively offered by CentOS, the first thing we need to do is make sure that yum can find the components we need. They are:

- Redhat Package Manager GNU Privacy Guard Keys (rpm-gpg)
- Extra Packages for Enterprise Linux (EPEL)
- Development Tools Group
- yum-utils
- The REMI Repository (to get diffferent versions of PHP)

Redhat Package Manager (RPM) GNU Privacy Guard (GPG) Encryption Keys:

Here's how to import the Redhat Package Manager (RPM) GNU Privacy Guard (GPG) Keys that will be needed to validate some of the packages we are going to need to add to the system.

The keys are located in the /etc/pki/rpm-gpg directory:

# cd /etc/pki/rpm-gpg
# ls -lZ
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-CentOS-7
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-CentOS-Debug-7
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-CentOS-SIG-SCLo
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-CentOS-Testing-7
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-EPEL-7
-rw-r--r--. root root system_u:object_r:cert_t:s0 RPM-GPG-KEY-IUS-7

OK, we know what we will be processing now, so it's time to issue an rpm command:

# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*

Don't be alarmed if you see no output from this rpm command. There should be some kind of output, but there isn't any, even if you use the -v or the --verbose option of the rpm command (sadly).

This step is complete.

Extra Packages for Enterprise Linux (EPEL) Repository

Here's how to gain access to the Extra Packages for Enterprise Linux (EPEL) Repository, which may not have been installed as part of your base CentOS installation, and which are going to be needed for this exercise:

# yum install -y epel-release

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirror.qoxy.com
* centos-sclo-rh: mirror.qoxy.com
* epel: my.fedora.ipserverone.com
* extras: mirror.qoxy.com
* updates: mirror.qoxy.com
Package epel-release-7-12.noarch already installed and latest version
Nothing to do

In my case, EPEL was already installed.

This step is complete.

Development Tools Group

Here's how to install is the Development Tools Group, which holds things like compilers, debuggers and make utilities. I am not entirely sure this is required by this installation, but I am including it because these tools are ultimately quite useful, and disk space is now so cheap their addition really won't matter.

First, check to see if it is accessible:

# yum group list
Loaded plugins: fastestmirror
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)
Loading mirror speeds from cached hostfile
* base: mirror.qoxy.com
* centos-sclo-rh: mirror.qoxy.com
* epel: my.fedora.ipserverone.com
* extras: mirror.qoxy.com
* updates: mirror.qoxy.com
Available Environment Groups:

Scientific Support
Security Tools
Smart Card Support
System Administration Tools
System Management
TurboGears application framework
Xfce

Done

OK, we have it, so let's install it.
The following command will install a bunch of packages on your machine (in my case, 58 of them), so just sit back and wait for the transaction to finish, and the word Complete! to appear, which means everything installed OK.

# yum -v groupinstall 'Development Tools'

Loaded plugins: fastestmirror
.
.
.

Complete!

This step is complete.

Install the yum-utils package:

Here's how to install the yum-utils package, which is a collection of tools and utilities for managing yum (Yellowdog Updater Modified) repositories. Again, I am really not certain this is required, but these tools are also handy to have around.

# yum -y install yum-utils
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirror.qoxy.com
* centos-sclo-rh: mirror.qoxy.com
* epel: my.fedora.ipserverone.com
* extras: mirror.qoxy.com
* updates: mirror.qoxy.com
Package yum-utils-1.1.31-52.el7.noarch already installed and latest version

Nothing to do

In my case, it was already installed.

This step is complete.

Enable and Install the Remi Collet (REMI) Repository & PHP-FPM Packages:

Remi Collet is a treasure to the CentOS community. He maintains a repository of software that has been prepared for installation on different versions of Red Hat Enterprise Linux (RHEL), CentOS and Scientific Linux.

Here's how to activate access to the REMI Repository:

# yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
Loaded plugins: fastestmirror
remi-release-7.rpm .
.
.
Complete!

Next, we need to make sure that the REMI Repository is available to CentOS 7:

# yum repolist

Loaded plugins: fastestmirror

Loading mirror speeds from cached hostfile

* base: mirror.qoxy.com

* centos-sclo-rh: mirror.qoxy.com

* centos-sclo-sclo: mirror.qoxy.com

remi-safe Safe Remi's RPM repository for Enterprise Linux 7 - x86_64 3,621

updates/7/x86_64 CentOS-7 - Updates 738

repolist: 39,040

OK, so now that we know the REMI Repository is available, we can use it to go and get the different versions of PHP that we need.

NOTE: For the sake of simplicity, I am going to take a chance and hope that PHP 5.6 is not going to significantly break my OLD website (PHP 5.3.3).

So the versions of PHP I want to install on the server are:

- PHP 5.6 (OLD website, of which there is only one)
- PHP 7.1 (NEW website + all other websites on this server)

Alright, let's start by installing PHP 7.1 on the server, because that's what my production website is running and what almost all of my other websites require.

First - How To Remove php71u From a CentOS 7 Server

To remove php71u from a CentOS 7 Server, you need to find the packages that were installed in its name. Here's how I found them:

# rpm -qa | grep -i php71u

php71u-cli-7.1.33-1.el7.ius.x86_64

php71u-mbstring-7.1.33-1.el7.ius.x86_64

php71u-pdo-7.1.33-1.el7.ius.x86_64

php71u-fpm-7.1.33-1.el7.ius.x86_64

php71u-process-7.1.33-1.el7.ius.x86_64

php71u-gd-7.1.33-1.el7.ius.x86_64

php71u-mysqlnd-7.1.33-1.el7.ius.x86_64

mod_php71u-7.1.33-1.el7.ius.x86_64

php71u-bcmath-7.1.33-1.el7.ius.x86_64

php71u-opcache-7.1.33-1.el7.ius.x86_64

php71u-pecl-igbinary-3.0.1-1.el7.ius.x86_64

php71u-pecl-memcached-3.1.4-1.el7.ius.x86_64

php71u-intl-7.1.33-1.el7.ius.x86_64

php71u-json-7.1.33-1.el7.ius.x86_64

php71u-xml-7.1.33-1.el7.ius.x86_64

php71u-common-7.1.33-1.el7.ius.x86_64

OK, now that we know what packages were installed, we can remove them all via a single yum command. Because php71u is the default PHP server right now, it can be removed by simply specifying "php" in the yum command:

# yum remove php*

# yum remove php*

How To Install PHP 7.1 Using the REMI Repository

To install PHP 7.1 as the default PHP version on CentOS, the system must be informed that the version of PHP on the machine has been changed away from whatever the previous default installation version may have been. This is done with the yum-config-manager command:

# yum-config-manager --enable remi-php71
Loaded plugins: fastestmirror
==================================================================== repo: remi-php71 =====================================================================
[remi-php71]

Now that the default CentOS 7 PHP configuration has been set to PHP 7.1, that version of PHP can now be installed via a regular yum command:

# yum install php php-common php-fpm

The complete REMI PHP 7.1 environment for CentOS 7 has been installed.

How To Test For A Working PHP 7.1 Installation

With REMI PHP 7.1 successfully installed, it's now time to re-start the apache server to see if there are any issues:

# service httpd restart
Redirecting to /bin/systemctl restart httpd.service

First, we should check the status of the apache server to make sure that it is happy:

# service httpd status
Redirecting to /bin/systemctl status httpd.service

Let's load a user space web page to make sure that customers can access the NEW eCommerce website, which runs on PHP 7.1:

The eCommerce website looks great - but warnings and errors are currently being hidden from users - how does the Drupal 7 Administrator GUI look?

No errors in the Drupal 7 Administration GUI either.

As a last check, let's investigate the PHP version offered up by the CentOS 7 CLI and Web interfaces:

How To Determine Current PHP version

There's a couple of ways to figure out what version of PHP is running on a CentOS server; One via the Command Line Interface (CLI) and another via the web interface using the phpinfo() command embedded in a very simple web page:

The CLI Method:

# which php
/bin/php
# /bin/php -v
PHP 7.1.33 (cli) (built: Oct 25 2019 01:51:40) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.1.33, Copyright (c) 1999-2018, by Zend Technologies

[root@vm rpm-gpg]#

According to the Command Line Interface (CLI) of my CentOS 7 server, the version of PHP I am running is 7.1.33.

The phpinfo() Method:

Just place a small file called phpinfo.php in any active website directory. Here's what needs to be inside the file:

<?php phpinfo(); ?>

Yes, it's a single line of code

Here's the result:

According to my CentOS 7 web server, the version of PHP I am now running is 7.1.33 , and I am using mod_php to process my PHP.

OK, looks like the PHP 7.1 installation was a great success!

But - What About The OLD eCommerce Website?

Enabling the REMI PHP 7.1 functionality is great for my NEW eCommerce website, which requires at least that version of PHP, but it is terrible for my OLD eCommerce website which requires at least PHP 5.3.3!

How To Run Two Versions Of PHP On The Same CentOS 7 Server

Running Two Versions Of PHP On The Same CentOS Server requires a few modifications to the stock CentOS installation:

1) The default PHP version needs to be downloaded and installed on the server, along with its PHP-FastCGI Process Manager (php-fpm) component. In my case, the desired default is PHP 7.1

2) The alternate PHP version needs to be downloaded and installed on the server, along with its PHP-FastCGI Process Manager (php-fpm) component. In my case, the desired alternate is PHP 5.6

3) The php-fpm instance for PHP 7.1 needs to be bound to a different server port than the php-fpm instance for PHP 5.6

4) The php-fpm server ports for both PHP 7.1 and PHP 5.6 need to be unblocked by SELINUX

4) The apache server needs to have its configuration adjusted to use php-fpm instead of its default PHP processor, mod_php.

5) All of the apache website configuration files need to be adjusted so the server knows which website needs to be connected to which php-fpm instance

6) The apache server needs to be restarted

7) The new apache configuration needs to be tested and proven to be working using either the CLI or the WWW interface (ideally, both).

How To Install PHP 5.6 (REMI Repository Version)

Now that we have PHP 7.1 installed as the default PHP version on the CentOS 7 Server, we need to install a parallel PHP 5.6 version.

Here's how to do that, using the REMI Repository:

# yum install php56 php56-php-common php56-php-fpm

How To Enable PHP-FPM On A CentOS Server

Now that PHP 7.1 and PHP 5.6 are installed on the CentOS Server, it's time to turn them on. Each of the two versions has a php-fpm instance associated with it, and here is the location of their configuration file, www.conf:

- PHP 7.1: /etc/php-fpm/www.conf
- PHP 5.6: /opt/remi/php56/root/etc/php-fpm/www.conf

These two instances need to be configured to listen to a different port, so apache knows what to send where given its different PHP contexts. Here's some settings that make sense:

- PHP 7.1: 9071
- PHP 5.6: 9056

Here's the relevant configuration change for PHP 7.1:

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
; will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = apache
; RPM: Keep a group allowed to write in log dir.
group = apache

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.

listen = 127.0.0.1:9071

Here's the relevant configuration change for PHP 5.6:

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; 'port' - to listen on a TCP socket to all IPv4 addresses on a
; specific port;
; '[::]:port' - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = 127.0.0.1:9056

How To Ensure php-fpm Ports Are Not Blocked By SELINUX

SELINUX blocks ports by default, so to allow the new php-fpm ports to function correctly, we need to tell SELINUX to open them up:

Here's the semanage command to open up the php-fpm port for PHP 5.6

# semanage port -a -t http_port_t -p tcp 9056

There is no output from this command.

Here's the semanage command to open up the php-fpm port for PHP 7.1

# semanage port -a -t http_port_t -p tcp 9071

There is no output from this command.

How To Configure apache To Serve Different PHP Versions

With php-fpm now installed, we can now tell apache which websites need which version of PHP to function correctly. On my system, websites are defined in the vhosts file, located in the /etc/httpd/conf.d directory.

Let's alter the definition for the OLD website, and tell apache that it needs to be processed by the PHP 5.6 related php-fpm instance that is listening to port 9056.

###############################################################################
# GL 2019-11-26 old.holisticpethelp.com
###############################################################################

</FilesMatch>

</VirtualHost>

How To Turn Off mod_php On A CentOS Server

Turning off mod_php on a Centos Server is pretty easy. You just go to /etc/httpd/conf.modules.d and edit the 15-php.conf file like so:

#
# PHP is an HTML-embedded scripting language which attempts to make it
# easy for developers to write dynamically generated webpages.
#

# Cannot load both php5 and php7 modules
<IfModule !mod_php5.c>
<IfModule prefork.c>
# GL 2019-11-27 Disabled to enable php-fpm elsewhere
# LoadModule php7_module modules/libphp7.so
</IfModule>
</IfModule>

<IfModule !mod_php5.c>
<IfModule !prefork.c>
LoadModule php7_module modules/libphp7-zts.so
</IfModule>

</IfModule>

The above changes prevent apache from loading mod_php.

How To Prepare A CentOS Server php.conf For php-fpm Instead Of mod_php

The CentOS Server php.conf file is located in the /etc/httpd/conf.d directory, and preparing it for php-fpm (instead of mod_php) is pretty straightforward.

Here's what my php.conf file looked like before the modifications for php-fpm:

# grep ^[^#] php.conf

Require all denied

</IfModule>

Order allow,deny

Deny from all

Satisfy All

</IfModule>

</Files>

AddType text/html .php

DirectoryIndex index.php

SetHandler application/x-httpd-php

</FilesMatch>

php_value session.save_handler "files"

php_value session.save_path "/var/lib/php/session"

php_value soap.wsdl_cache_dir "/var/lib/php/wsdlcache"

#php_value opcache.file_cache "/var/lib/php/opcache"

</IfModule>

Here's what my php.ini file looked like after the modifications for php-fpm:

# grep ^[^#] php.conf

<Files ".user.ini">
<IfModule mod_authz_core.c>
Require all denied
</IfModule>
<IfModule !mod_authz_core.c>
Order allow,deny
Deny from all
Satisfy All
</IfModule>
</Files>
AddType text/html .php
DirectoryIndex index.php
SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=$1
<FilesMatch \.php$>
SetHandler "proxy:fcgi://127.0.0.1:9071"
</FilesMatch>

NOTE that the entire stanza for IfModule mod_php7c has been removed!

How To Activate php-fpm 7.1 On A CentOS Server

With the CentOS Server now configured to use php-fpm instead of mod_php, it's time to activate the php-fpm module, bump the apache server and see what happens!

First, start the php-fpm component for PHP 7.1

# systemctl start php-fpm

Next, enable the php-fpm component for PHP 7.1

# systemctl enable php-fpm

Created symlink from /etc/systemd/system/multi-user.target.wants/php-fpm.service to /usr/lib/systemd/system/php-fpm.service.

OK, time to bump the apache server

# service httpd restart
Redirecting to /bin/systemctl restart httpd.service

Let's see if the the apache server liked being bumped:

[root@vm conf.d]# service httpd status
Redirecting to /bin/systemctl status httpd.service
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)

OK - let's see what version of PHP is running on the NEW eCommerce website:

According to my CentOS 7 web server, the version of PHP I am now running is 7.1.33 , and I am using php-fpm to process my PHP, which means everything has worked out so far!

How about the User and Administrator websites? Are they OK?

How To Activate php-fpm 5.6 On A CentOS Server

OK - now for the acid test. Can my OLD website function properly now that php-fpm has been installed?

First, start the php-fpm component for PHP 5.6

# systemctl start php56-php-fpm

Next, enable the php-fpm component for PHP 5.6

# systemctl enable php56-php-fpm
Created symlink from /etc/systemd/system/multi-user.target.wants/php56-php-fpm.service to /usr/lib/systemd/system/php56-php-fpm.service.

Now bump the apache server

# service httpd restart
Redirecting to /bin/systemctl restart httpd.service

See if the the apache server liked being bumped:

# service httpd status
Redirecting to /bin/systemctl status httpd.service
● httpd.service - The Apache HTTP Server
Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled)
