CentOS 7 & PHP 7.4
YUM
Assuming EPEL and REMI are installed
sudo yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm sudo yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
Make sure your system has
sudo yum -y install yum-utils sudo yum-config-manager --enable remi-php74
Make sure your system is current
sudo yum update
Issues
During the yum update I got this error:
Transaction check error: file /usr/lib64/libMagickCore-6.Q16.so.6.0.0 from install of ImageMagick-6.9.10.68-3.el7.x86_64 conflicts with file from package ImageMagick6-libs-0:6.9.11.6-1.el7.remi.x86_64 file /usr/lib64/libMagickWand-6.Q16.so.6.0.0 from install of ImageMagick-6.9.10.68-3.el7.x86_64 conflicts with file from package ImageMagick6-libs-0:6.9.11.6-1.el7.remi.x86_64
This is not uncommon, specially if it has bee a while since you did a full upgrade.
We remove the offending RPM and reinstall it later.
sudo yum remove ImageMagick
In this case this also removed caja-image-converter & emacs. Removing emacs is a little bit major, and if you have more than a couple of other files that want to be removed, do a google search to see what others have discovered. Now back to...
sudo yum update
Interesting to note
During my upgrade this is what was going to happen.
Transaction Summary ============================================== Install 4 Packages (+14 Dependent packages) Upgrade 616 Packages Remove 2 Packages Total size: 1.1 G
Quite a reasonable upgrade, it has been a few months since I did a full upgrade. You do want to stay up to date, for bug fixes and security patches.
You will notice that 4 new packages are being installed and 2 removed. This is the nature of the opensource community. Someone may have written a package that helps you rotate pictures from the Command Line, as this has been worked on, many people from different professional and different countries have worked on this free. A new way may have been found to do this job better, and the time may have come, instead of updating a package, a better and more versatile package has been written, hence an old one is deleted and a new one installed.
Once the upgrade is done, I do it again, just in case, there were any dependant upgrades that could be done the first time. This actually happened for me as the first time I ran
sudo yum update
I only had 14 MB of upgrades, the second time 1.1 GB
Also I reinstalled the packages I previous deleted.
sudo yum install ImageMagick caja-image-converter emacs
I now have a successful and full upgrade, on to the rest.
YUM Continued

DONE!
Symfony
In your Symfony development area run the command for the console. For Symfony 4.2, something like
php -S 127.0.0.1:8000 -t public
It should return
[Tue Oct 6 08:56:55 2020] PHP 7.4.11 Development Server (http://127.0.0.1:8000) started
OR for Symfony 4.4 or 5.1
symfony server:start
This returned
Version 4.19.0 is available (currently running v4.16.3). Do you want to update now (execution will continue after whatever you decide) ? [Y/n]:
I said Y and once completed did a restart
symfony server:start
[WARNING] run "symfony server:ca:install" first if you want to run the web server with TLS support, or use "--no-tls"
to avoid this warning

What did all this mean?
- In development I do not what to run with encryption.
- We are running PHP 7.4.11, good.
- The web server is listening on power http://127.0.0.1:8000
- php-fpm is running on port 35596, The “FPM” part in PHP stands for “Fast Process Manager”, which is just a fancy way of saying that the PHP running on a server isn't a single process, but rather some PHP processes that are spawned, controller, and killed off by this FPM process manager. https://geekflare.com/php-fpm-optimization/
