Nightmare with 3 web domains one displays local but web pages do not show on internet

I ran the suggested program getinfo.sh network and the results are at PasteBin

After 2 weeks and a lot of reading I have One site loading on the localhost but the other 2 web sites error out. None show on the internet.
Centos 5.8 is what I installed on a standalone system.

I have a block of 5 IP addresses with 3 that I have domain names for. I just renewed the base IP address for another 5 years.
I need to run the 3 domains on Centos5.8, I also have 3 other computers. 2 XP boxes, one a laptop and a Win7 box.
I did have 78ez.com running from a win95 then a XP and finally win7 all with Apache. but the attacks killed me so I now need more security so I put centos5.8 on a separate computer.

I can pull files to/from the windows boxes and Centos 5.8
What I need to know is how to get these web sites to show on the internet please.
AND/OR if anyone knows the
1.basic setup needed to run a Linux web-server I think way too much software is installed. Granted I do not know what most of it is and internet research for 258 programs is mind numbing at best.
2. when your web pages show on local-host but not on the internet what is the most likely reason. Or is there a step by step resource you can follow to trouble shoot the reason?

I did add to IPTABLES.conf
-A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 80 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -p tcp --dport 443 -j ACCEPT
the boot log says it can't find the command?

From what I understand, you have a web server with the private (non-routeable) IP address 192.168.0.65, and you wish this server to serve web pages for three different domains, and for these sites to be available from the Internet.

This is what you need to do:

Install the necessary web server software on the server

You've done this already. As for exaxtly what software you need, the answer is "it depends". You will always need the web server siftware itself, such as Apache, LigHTTPD or Nginx. In addition, you may need to install languages like PHP, Python or Perl if your web pages uses server side scripting (most do), and perhaps a database engine like PostgreSQL or MySQL, if the scripts make use of a database.

I quite agree with your assessment that your CentOS server probably has a lot of unneeded software installed, and that the number of installed packages should be kept at a minimum for maintenance and security reasons.
Configure your web server to serve the sites in question

You've done this too, using the Apache VirtualHost directive. Whenever a client requests a web page from a server, it specifies both the file name and the site name. This is how a web server can serve multiple sites using a single IP address.
Make the server accessible for Internet clients

Your server needs a public (routeable) IP address for this to work. You can either connect the server directly to a network using public IP addresses, or you can forward a port from a router/server with such an address.

According to the information you've posted, your server has a private IP address. This is fine, as long as you can forward ports 80 and 443 from a host or router that has the desired public IP address.
Make an DNS A record that points from the server name (typically www.domain.com or somesuch) to the IP address of the server

You need to add this record to the authoritative DNS server for the domain(s) in question. This is most likely a DNS server run by the registrar with whom you registered your domain. The A record must point to a public IP address. If your server has a private IP address and you wish to forward port 80 from a router, the A record should point to tha IP address of that router.

I see that for testing purposes, you've added the domain name to the hosts file of a local PC and pointed it at the private IP address of the server. This makes it possible to perform necessary testing without exposing the server to the Internet, which is great, but as mentioned, you also need to add a record to the domain zone on the public Internet.

If you do this, your sites should be visible to anyone on the Internet.

Missing DNS records or firewall/port forwarding issues. Here are some tests you can run:

1. Run nslookup www.yourdomain.com authoritative.dns.server

This command works on both Linux and Windows. "www.yourdomain.com" should obviously be replaced with the name you wish to test, while "authoritative.dns.server" should be the name or IP address of the DNS server responsible for that domain. (You can find the IP address of that server with nslookup -q=NS domain.name - note that the "www" part should not be included, just the domain.)

The command should return the public IP address of your server (or the server/router doing the port forwarding). It should NOT return a private IP address.

2. Test the availability of the HTTP/HTTPS service (port 80 and 443 respectively) using an external service like ShieldsUP!

If run from the web server, the test should report ports 80 and 443 as open. If not, your server can't be accessed from the Internet.

I'm not sure what iptables.conf on CentOS is supposed to contain, but according to the CentOS documentation you can add the necessary rules to the firewall from the command line and then run service iptables save.

You need to specify an address that is actually assigned to the server in question. Unless one of the network interfaces on the server has one of those IP addresses, it won't work.

If your server is to have a private IP (as it has now), you could enter that IP address or just leave the asterisk.

This should cause the server to accept requests for web pages in the site "www.xxxezhosting.com" and look for those pages in the /var/www/html/xxxhosting directory.

BTW, you have another virtual host serving pages from the /var/www/html directory. Unless you specifically want it for some reason, it probably isn't a great idea to have one site serving pages from a subdirectory of another site.
