hi community, hope everyone is safe and well.
I know there are multiple topics related to firewalld task but i could not find help in any on them (sorry if i missed something).
Since this is my first contact with Linux firewalls and firewalld in general.
- i checked the zone and it was public on all 3 app servers.
- nginx and httpd (apache) service was started and running properly.
- i did firewall-cmd --add-port=xxxx --permanent of nginx port for incoming access to the port itself (port is in the conf file if i am right?)
- lb access to httpd - do i add (append) the line Listen IP:port to the apache conf file (i could seem to install vim or any other editors like nano or emacs) or do i do it other way?
could someone more experienced comment what i did wrong and give some pointers for me?
When i finished the task i failed and it said LB cant access apache port.
i got the same task 2 times in 2 days without even trying for the first time, is that a bug or?
since i failed both of the tasks can i espect to get it some time soon or?
A big thanks to everyone taking the time and helping out a rookie in need.
