I am having trouble with my httpd.conf file in RedHat 7.6. I cannot get port 80 or port 443 to recognize on start up. I can get port 8080 or port 8443 to recognize after the installation of a SSL from Digicert. If someone would be so kind as to help me through this process.

/etc/httpd/conf/httpd.conf
Listen :443

# Custom Virtual Hosts

if I change my port to 8080 I can see this:
# lsof -i :443

Any help would be great

Try to see what processes are listening on which port.

Otherwise, it's not clear what you mean my "having trouble" Please further explain the issues.

What to you mean by "recognize"?
This doesn't make sense to me. You say that when you set the Listen port to 8080, apache listens on 443? Do you mean that before reconfiguring the Listen port to 8080, it did not listen on 443?

By the way, it seems to me that you need two Listen directives in httpd.conf, one for 80, one for 443.

My suggestion: Go back to the previous configuration (default ports 80 and 443), and describe precisely what is wrong. E.g. you perform a certain action and get error messages, or unexpected behaviour.

Good evening. With the /etc/httpd/conf/httpd.conf set to Listen :8080 this is the result of netsat -tlnp

this is my problem

https://httpd.apache.org/docs/2.4/bind.html

Overlapping Listen directives will result in a fatal error which will prevent the server from starting up.

(48)Address already in use: make_sock: could not bind to address [::]:80

See the discussion in the wiki for further troubleshooting tips.

https://wiki.apache.org/httpd/CouldNotBindToAddress

Request: It would really make the text more readable if you put it into code tags.

Hint: You can see all httpd log messages with journalctl -u httpd.

Guess: When you try to start a web server, another one is still running, causing the address in use error. Don’t use systemctl start, but systemctl restart or even reload. Or explicitly stop the server systemctl stop before starting it.

There are two "Listen 443" directives, so apache tries to open the same port a second time and it complains.

Please notice that there is the file /etc/httpd/conf.d/ssl.conf that is included by default in the main /etc/httpd/conf/httpd.conf, where you should configure everything regarding SSL.
In that file there is a "Listen 443" directive too.
So move the SSL configuration from the main /etc/httpd/conf/httpd.conf to /etc/httpd/conf.d/ssl.conf and you'll be ok.

I did all of that. Can't figure out why Firefox times out.

You should first check if apache is running and listening on the default ports:

In https://www.linuxquestions.org/quest...4/#post5977069, firefox times out because port 8080 is (probably) protected by the firewall, and Apache doesn’t listen on any other IPv4 port.

I got it working on the following port

https://www.linuxrpms.com:8080

But the standard port of 443 does not want to seem to work

In the /etc/httpd/conf.d/ssl.conf file it is listed as

Listen 8080 https

If I change it to

Listen 443 https

Firefox times out

As others have said above, maybe port 443 is closed by your ISP

Try:

To view your firewall rules. It should be somewhat intuitive. Most of the command line switches should be somewhat intuitive based on their arguments. When a packet matches -j ACCEPT, -j REJECT or -j DROP processing will stop and the -j action will be performed.

Where is the Firefox browser; local machine or different?
After changing to port 443, stop/start httpd. Then look at "netstat -tanpl|grep httpd" output.
Also, try "telnet localhost 443"
If that connects, your httpd config is working.

8080 and 8443 are tomcat ports (java)

for httpd have a look for/at/in /etc/httpd/conf/ports.conf or possibly /etc/httpd/ports.conf
