FOG server under RHEL 9 and PHP 8

[Fernando Gietz]

Hi again! I am back
I am installing a new server under RHEL 9, but I am having problems with the install process.

Two big problems:

• PHP version 8: the implode function is deprecated and have changed (https://www.php.net/manual/en/function.implode.php)

 implode(string $separator, array $array): string

Alternative signature (not supported with named arguments):
implode(array $array): string

Legacy signature (deprecated as of PHP 7.4.0, removed as of PHP 8.0.0):
implode(array $array, string $separator): string

Join array elements with a separator string. 

The order of the parameters is different. This affects to all calls of the implode function.

*xinetd package is not available in RHEL 9
From https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/pdf/considerations_in_adopting_rhel_9/red_hat_enterprise_linux-9-considerations_in_adopting_rhel_9-en-us.pdf

The xinetd package is not available in RHEL
9. Its functionality is now provided by
systemd.

Workaround: Install php 7.4 in RHEL 9
Install PHP 7.4 (https://www.linuxcapable.com/how-to-install-php-on-centos-stream/)

# dnf upgrade –refresh
# dnf config-manager --set-enabled crb
# dnf install \
    https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm \
    https://dl.fedoraproject.org/pub/epel/epel-next-release-latest-9.noarch.rpm
# dnf install dnf-utils http://rpms.remirepo.net/enterprise/remi-release-9.rpm -y
# dnf module list php
# dnf module enable php:remi-7.4 –y
# dnf install php php-cli php-common php-fpm php-gd php-json php-ldap php-mbstring php-mysqlnd php-process –y

@Fernando-Gietz Hi Fernando, great to see you around!

I guess you tried to install FOG 1.5.9. This version still lacks PHP 8 support. Either install dev-branch (you can easily update from dev-branch to the next official release) or wait two weeks until the new release is out.

@Sebastian-Roth Hi Sebastian!
I will try the dev-branch, the new server is the develop server. If the new release version has PHP 8 support then great
The problem with the xinetd is more “special”, only affect to RHEL 9 and higher.

Not exactly sure but back in my head this rings a bell. We might have fixed that in dev-branch as well.

Hi @Sebastian-Roth,
Yes, I think that the dev-branch solves the problem. I tried to install from master branch and the problem with the xinetd appeared, but with the dev-branch apparently works fine
