RE: Problems with "VirtualHost" (Apache Users)

Hi,

I define both vhost with <hostname>:<port> because each “hostname” links to different hosts. Machines A and B are differents and they are serving its sites, so in Apache I must declare (I think…) each host because I need to differentiate them. If I use *:<port>, how are I differentiating both hosts if they are different?

Output of “apachectl -S”:

in my running R (CentOS), where redirection works:

VirtualHost configuration:

my_ip_address:80 is a NameVirtualHost

Hello,

I have a small Apache where I run a redirection to two private hosts. My machine (R, router) is connected to Interned and to a private LAN (192.168.x.x/16). Behind “R”, there are two machines (A and B) that are serving two websites. R has an DNS alias with two public DNS names for A and B (because some years ago, A and B were machines with public IP addresses). Now, I want to change R and configure a new R machine (newest distribution). However, in new R, redirect doesn’t run and I can’t get browing from Internet to A and B websites. I copypaste here all information:

R:

CentOS-7.9.2009
Apache: 2.4.6-99.el7.centos.1

new R:

Rocky Linux 8.9
Apache: 2.4.37-62.module+el8.9.0+1436+2b7d5021

My configuration file where I have configured “VirtualHost” is the same in both servers:

<VirtualHost A.mydomain:80>

        ServerAdmin foo@boo

        ServerName A.mydomain

        ServerAlias A A.mydomain

                </RequireAny>

        </Directory>

</VirtualHost>

<VirtualHost B.mydomain:80>

        ServerAdmin foo@boo

        ServerName B.mydomain

        ServerAlias B B.mydomain

        LogLevel info

        ErrorLog /var/log/httpd/virtualhost-B.log

        ProxyPass / http://192.168.1.5/

        ProxyPassReverse / http://192.168.1.5/

        <Location />

                <RequireAny>

                        Require ip my_network

                </RequireAny>

                AllowOverride all

                <RequireAny>

                        Require ip my_domain

                </RequireAny>

        </Directory>

</VirtualHost>

With this file, in server R, redirection runs perfectly and when I browse http://A/mysiteA, R redirect connection to private machine A (the same when I browse to http://B/mysiteB). However, in new R, when I browse to http://A/mysiteA (or http://B/mysiteB), there are no redirection and I can see at logs this message: File does not exist: /var/www/html/mysiteA (or File does not exist: /var/www/html/mysiteB).

Where is the problem?

Thanks!

You don't want to define a vhost as <hostname>:<port>, unless you know exactly what you are doing. When unsure, always use *:<port>.

Show the output from apachectl -S or httpd -S after you applied the fixes.
