CentOS 7: Apache Wont start after configuring virtualhost

Submitted by wheeler on Mon, 09/08/2014 - 09:07

Operating System CentOS7 not available, so I chose CenOS/RHEL 6 but this only applies to CentOS 7

I setup a test virtual host on a new install of Virtualmin on CentOS 7, and shortly after noticed Apache was not running. On attempting to start it I got:


Failed to start service :
Redirecting to /bin/systemctl start httpd.service
Job for httpd.service failed. See 'systemctl status httpd.service' and 'journalctl -xn' for details.

systemctl status httpd.service says:

/etc/httpd/conf.d/ssl.conf contained the following


#
# When we also provide SSL we have to listen to the
# the HTTPS port in addition.
#
Listen 443 https
Listen ***.***.***.***:443

(Real external IP replaced with ***.***.***.***)

It was trying to bind twice to 443, commenting out the second line allowed Apache to start

I also noticed this bug yesterday, and have implemented a fix for inclusion in the next Virtualmin release (4.11). The cause is that the first Listen line has a port name at the end of it (https) which confuses Virtualmin.

The fix is simply to change the line to :

Listen 443

and remove the second Listen with the IP address in it.
