Got a different problem. I ran the port change command...
1. On the httpd.include files for each domain
2. On zz010_psa_httpd.conf
3. Changed the listen directive in httpd.conf
This went ok and I verified they all changed ok.
However when I tried to restart httpd, I get the following
[warn] VirtualHost IP_1:80 overlaps with VirtualHost IP_1:80, the first has precedence, perhaps you need a NameVirtualHost directive
[warn] VirtualHost IP_2:80 overlaps with VirtualHost IP_2:80, the first has precedence, perhaps you need a NameVirtualHost directive
[warn] VirtualHost IP_3:80 overlaps with VirtualHost IP_3:80, the first has precedence, perhaps you need a NameVirtualHost directive
The weird thing is that there is nothing with IP:80 in any of the config files and when I tried a change back to Port 80 and restarted httpd, I started getting the same messages but with Port 81 instead.
I added "NameVirtualHost *:80" to the list of NameVirtualHost IP:81 in zz010_psa_httpd.conf as a test, I got a message saying there where no virtual hosts at Port 80.
I have not yet bound anything to Port 80 but still surprised that after changing the Apache Port, I am getting warning messages related to the old location.
Any insight will be appreciated.
