My operating system is Red Hat Enterprise Linux 7. This isn't working...
# httpd -t
bash: httpd: command not found
In case it helps, this is the command I run to restart apache on this box...
# systemctl restart httpd24-httpd
But this doesn't work...
# httpd24-httpd -t
bash: httpd24-httpd: command not found
This doesn't work either...
# apachectl -t
bash: apachetl: command not found
Nor does this work...
# apachectl configtest
bash: apachetl: command not found
I know this is a couple months old but ended up here. I ran into the same issue initially, hence why I am here. I found that the location for the new httpd24-httpd wasn't in my env path to execute. While I could added it there, I found the command location and was able to execute.
How I found the command:
sudo find / -name apachectl
The output of the command:
/opt/rh/httpd24/root/usr/sbin/apachectl
Executed the command:
sudo /opt/rh/httpd24/root/usr/sbin/apachectl
Turns out I have to fix my configuration.
httpd: Syntax error on line 56 of /opt/rh/httpd24/root/etc/httpd/conf/httpd.conf: Syntax error on line 40 of /opt/rh/httpd24/root/etc/httpd/conf.modules.d/00-base.conf: Cannot load modules/mod_http2.so into server: libnghttp2-httpd24.so.14: cannot open shared object file: No such file or directory
Interesting that this came up for me, as I've not done anything with the configuration in this regard.
Here's the version I am running.
sudo /opt/rh/httpd24/root/usr/sbin/apachectl -v
Server version: Apache/2.4.34 (Red Hat) Server built: Mar 17 2020 09:34:59
All the best!
Found something more for this as well from an old bug submitted to Redhat
