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

Re: [CentOS] Apache (httpd) fails to start at boot - Centos 8.1
Thanks to all that responded. Gordon's suggestion worked brilliantly. I ran the suggested command, saved the file, rebooted, apache came right up. Can't thank you guys enough. Now, lets try to solve my intermittent connectivity issue, more on that later...

Re: [CentOS] Apache (httpd) fails to start at boot - Centos 8.1
Just a wild guess, but it sounds like Apache is being started before the network is online.Is this host simple static Ethernet or DHCP, or is it something more complicated like WiFi? I believe you can set service dependencies with systemd, ideally your apache service isn't started before the network is online. If you are using WiFi, running a webserver is a bit ugly, perhaps configuring Apache to listen to 0.0.0.0 (all interfaces) would be a better choice? ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

That's half right now, but still not good enough. If the RPM provided file changes, your copy won't get those changes. To make this work better, don't put the full file in /etc/systemd/system but just add an override.conf there which is like a diff to the original file. That way updates of the RPM are handled correctly. Simon ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Apache (httpd) fails to start at boot - Centos 8.1
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.
