Apache not seeing website - CentOS 7 - php

Question

I have setup a lot of Virtual Hosts in Ubuntu but today I needed to do this on a CentOS 7 server. I installed Apache and setup the VHost config but nothing appears when I view the site.
I know that Apache is reading my Config files because if I add a fault in it and restart Apache, it complains about the error. Is there something "else" that is needed on CentOS 7?

Answer 1

What kind of virtualhosts are you trying to achieve? name based I guess.
If you are not running on version 2.4> then you need to enable the name virtual host directive for the IP:PORT pair
NameVirtualHost *:80
The different behavior can depend on the different versions of the Apache servers shipped with the distro.
If not, it could be depending on selinux labels not being set properly. In this case anyway, you would get a permission error. Honestly I don't believe this is the case.

Answer 2

This is the settings that I use on a CentOS 7.3.1611 running Apache 2.4.6 I normally use virtualmin / webmin for configuration, but I have looked at the httpd.conf The basic settings that are in my config are
<VirtualHost xxx.xxx.xxx.xxx:80>

The settings here set up two virtual websites using port 80 and bound to the same single IP , this is accessable by using http://servername or http://ServerAlias The DocumentRoot is the location of the files to be servers.
The second VirtualServer is basically the same set up, but it also shows how the Alias section can be used to pull documents from outside the main directory.
As a side note, if anyone spots any vunerabilities in what is posted, let me know or edit and let me know.

Answer 3

So the answer to this was that the CentOS server had (by default) blocked the HTTP port 80. This really seems a bit silly but as soon as I allowed the firewall to open these ports for the web traffic, all worked fine:
iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT

Answer 4

I try firewall-cmd --add-service=http on Centos 7.5 and it work
