Re: Apache2 fails to listen on open port

[Frank Gingras <thumbs@xxxxxxxxxx>]

So you clearly had two listen directives for the same port; remove one.

Thanks. My understanding is "systemctl restart apache2” waits the appropriate amount of time between the stop and start.

Try 

systenctl httpd stop, 

then when ps -ef | grep httpd shows that httpd is gone

systemctl httpd start

to give the system time to release all the resources.

Thanks for the info. However, I don’t believe any of the problems suggested in
the wiki apply.

1. The output from both lsof and netstat -plant indicate no other process is
using port 4443 either before or after apache2 is started

2. There does not seem to be conflicting Listen commands in the apache sites-
available files.

3. The Listen in 000-default.conf is: Listen localhost:4443 ssl; and the
Virtual Host entry is: <VirtualHost localhost:4443> ServerName
coop.mountolive.com:4443 … localhost and coop.mountolive.com are both valid
values as is port 4443.

4. I believe systemctl status apache2.service starts apache2 as root

5. SELinux is not active, i.e.,

semanage port -l|grep http
Command 'semanage' not found, but can be installed with:
sudo apt install policycoreutils-python-utils

I have attached output from the terminal commands that tests these hypotheses
to this message, as it is fairly long and including it in the body of the
message might make it hard to analyze.

By the way, the apache2 version is: Server version: Apache/2.4.29 (Ubuntu)
Server built:   2022-06-23T12:51:37
