Inconsistent httpd detection

[jesusbagpuss]

In some cases, the ps -C command is passed multiple variants of the apache process name e.g.

apache2buddy/apache2buddy.pl

Line 1824 in ad2e384

my @process_info = split(' ', `ps -C 'httpd httpd.worker apache apache2 /usr/sbin/httpd /usr/sbin/httpd.worker' -f | grep '^root'`);

In the main program loop, only 'httpd' and 'apache2' are checked:

apache2buddy/apache2buddy.pl

Line 2880 in ad2e384

our $httpd_detected = `ps -C httpd -o rss | grep -v RSS`;

apache2buddy/apache2buddy.pl

Line 2891 in ad2e384

our $apache2_detected = `ps -C apache2 -o rss | grep -v RSS`;

causing apache not to be detected in some cases (e.g. RHEL9.8).

Hi

I've not been able to support RHEL properly since RHEL7 when I had access to servers at work.

At that time httpd was the process name for Red Hat variants and apache2 was the process name on Debian variants.

It sounds like something has changed on the RHEL 9 builds that I no longer can see.

If you put a pull request in from staging, I can run it through the Jenkins pipeline for the docker containers I have and check it doesn't break anything and I'll approve it.
