CentOS - Jun 2020 - Apache (httpd) fails to start at boot - Centos 8.1

If I do 'systemctl start httpd', apache will start right up.  But during
boot, it doesn't and I
get the resulting errors below.

Jun 15 21:17:28 dream httpd[1534]: (99)Cannot assign requested address: AH00072:
make_sock: could
not bind to address 10.20.30.11:80
Jun 15 21:17:28 dream httpd[1534]: no listening sockets available, shutting down
Jun 15 21:17:28 dream httpd[1534]: AH00015: Unable to open logs
Jun 15 21:17:29 dream systemd[1]: httpd.service: Main process exited,
code=exited, status=1/FAILURE
Jun 15 21:17:29 dream systemd[1]: httpd.service: Failed with result
'exit-code'.

the box's ip address is 10.20.30.11, and I am trying to get http (80), and
https (443) going.

Firewall is turned on. The listen parameter in httpd.conf is 10.20.30.11:80  The
log files in
/var/log/httpd are all owned by root.  Httpd runs as user 'apache'.

Google searches have not returned anything that looks remotely promising.

Got any suggestions?

Thanks in advance,

Jay

I have always had exactly the same problem. I had to write a script and 
run it at boot time:

sleep 10
/usr/bin/systemctl start httpd

Must be some timing problem with the interface addresses not being set 
up in time.

Could some transient service be holding port 80 at that time?

You could probably arrange to run a script that runs "lsof -i" and
"ip
addr show", dumping the output to a temp file, just before httpd runs to 
see what's not set up right.

httpd is starting before an interface has been configured with 10.20.30.11.

The default configuration starts httpd after "network.target" but you 
want to start it after "network-online.target".

IIRC: run "systemctl edit httpd.service" and insert:

[Unit]
After=network-online.target

This happened to me with ssh.

Thank you Gordon. That works for me. 8.2 needs the same fix.
