NGINX UNIT "PHP" application is not supported on RHEL 9

[mikehillbilly]

We are running Drupal 10 which requires PHP8.1. Recently the University has given me a RHEL 9 Box so I am busy porting our websites over.
In the course of things I thought it would be a good idea to upgrade NGINX to UNIT but I cannot configure a PHP app in the UNIT configuration without a PHP error;

I've tried the generic "php" and specifying the version "php 8.1.27"

cat unit.json.conf | curl -X PUT -d@- localhost:8000/config
{
"error": "Invalid configuration.",
"detail": "The module to run "php 8.1.27" is not found among the available application modules."
}
[root@jbidevlin03 jbi]# php --version
PHP 8.1.27 (cli) (built: Dec 19 2023 20:35:55) (NTS gcc x86_64)

[root@jbidevlin03 jbi]# rmate unit.json.conf
[root@jbidevlin03 jbi]# cat unit.json.conf | curl -X PUT -d@- localhost:8000/config
{
"error": "Invalid configuration.",
"detail": "The module to run "php" is not found among the available application modules."
}

UNIT installation requires "yum install unit-php"
but I get this error;
yum install unit-php

So I have decided to go back to vanilla NGNIX unless someone can advise me how to fix this?

Thanks in advance

If you have Drupal 10.2 or 10.3 that should work with php 8.3, otherwise I expect you may need to build the unit-php module from source.

Caveat Emptor... as usual...

You'll need to install the php 8.1-devel package and perhaps the php 8.1-embedded package if it isn't already.

You'll also need to grab the unit source and build the php language module, something along the lines of...

$ git clone https://github.com/nginx/unit.git
$ cd unit
$ git checkout -b 1.32.1
$ ./configure # shouldn't need to specify the various paths etc as we're only going to copy out the php language module
$ make -j4
$ ./configure php # If that fails you may need to specify --config to point to the appropriate php-config file for your php 8.1 e.g './configure php --config=/path/to/php81-config'
$ make
# cp build/lib/unit/modules/php.unit.so /usr/lib64/unit/modules/

Restart Unit and it should pick up your newly built module, it will simply be called php in your unit config.

Thanks so much Andrew. I'll give it a go.

Yeah rebuilt PHP 8.1 per steps above and restarted unit but still get the same error
installed PHP 8.3 restarted unit and still get the same error.

I think I'll go back to NGINX for now.

Thanks for your help

I'm sorry we weren't able to resolve this for you; I do see unit-php RPMs for RHEL9 in our repository at https://packages.nginx.org/unit/rhel/9/x86_64/RPMS/ - I'm not sure why you're not seeing it on your end.
