Description Philip Prindeville 2017-10-26 19:21:58 UTC

Description of problem:

If your network is slow coming up (say you're using DHCP and the server is unavailable or rebooting after a power outage, etc) then this service might come up before the network is sufficiently configured.

Recommend adding

[Unit]
Wants=network-online.target
After=network-online.target

to .service file.

Version-Release number of selected component (if applicable):

httpd-2.4.28-1.fc26.x86_64

How reproducible:

Bring up host while DHCP server is down.

Steps to Reproduce:
1. Provision host to use DHCP
2. Shutdown DHCP server
3. Reboot host under test

Actual results:

Service requires host's IP address and hostname to properly operate

Expected results:

Service should not be started until network is adequately configured.

Affects rawhide / fc27 as well

Comment 2 Joe Orton 2017-11-28 13:00:18 UTC

In the default configuration, the service does not depend on specific IP address availability, thus the default httpd.service does not need to require network-online.target.  As documented in httpd.service(8), non-default configurations which enable httpd at boot time will need to be configured appropriately.
