How to setup Subdomains for Geoserver WMS with Apache and Tomcat - apache

We are running a bunch of WMS with a GeoServer. The GeoServer is running inside a tomcat webserver and the tomcat is behind an apache webserver.
At the moment we can reach our WMS like this: http://domain.com/geoserver/layer/wms?....
What we need are different subdomains for the WMS, that all point to the same GeoServer intance, e.g.:
http://t1.domain.com/geoserver/layer/wms?....
http://t2.domain.com/geoserver/layer/wms?....
http://t3.domain.com/geoserver/layer/wms?....
Any ideas how we can achieve/configure this with the configuration mentioned above?

I'm not sure if you can do that with Apache/Tomcat. The domain/subdomain names are the way other hosts reach yours, and after they find it is when Apache and Tomcat come into play.
You should ask your network admin of Internet provider for that or maybe think of another approach like http://domain.com/t1/geoserver/layer/wms?... http://domain.com/t2/geoserver/layer/wms?, etc.
I suggest you Varnish reverse proxy as it is a light-weight software with an easy configuration language.

Domain name and SSL for tomcat web app

The question I am raising here has been asked couple of times and I went through most of them, including stackoverflow posts and other blog posts. The case is that I couldn't find something which fits to my requirement and I'm not gonna play around in our product environment with suggestions.
So the situation is, we have multiple web applications hosted in our tomcat server, deployed in Amazon AWS. Currently we access them like http://<ip-address>:8080/webapp1. Now,
We have sub domains to point at our web apps. So something like portal.example.com will point the above URL.
We have wildcard SSL to implement for domains and sub domains.
Now, first I have to sort the domain pointing thing, which I found 2 separate ways.
Install Apache and do a Virtual Proxy (https://www.digitalocean.com/community/questions/how-to-tie-domain-name-with-application-running-on-tomcat)
Edit Serverl.xml (How to map tomcat 7 webapp to my domain)
Now my questions.
Can someone please advice which method is the best (If non is good, I'm open for others as well).
Which method makes the SSL implementation easy?
If I chose the Apache Virtual Proxy, where should I install SSL? In apache or in Tomcat?
If I chose Server.xml, where should I install SSL? In apache or in Tomcat?

On openshift, is there any apache at front of my tomcat server?

when https is used on openshift, is my tomcat behind an apache server?
I mean does my clients connect to my tomcat directly or they connect to the apache server, and then the apache server connect to my tomcat through AJP connector?
If apache is the man in the middle, then I will not get my clients' IP address directly, but with x-forward http header. And I lose the control over certificate verification and trust management. At present, I am using mochahost's server. https does not get to my tomcat, but intercepted by an apache. I hate this.
Previously, I used another hosting service, even 2 apache servers are at front of my tomcat server. Even more ridiculous that 2 apache servers and my tomcat servers are on the same machine. This kind of configuration can only show the system architecture does not have the right ability to manage the whole thing.
By the way, I am talking about the Bronze/Silver plan. I guess Openshift is not different though I have not tried it yet. Anyone has a clear answer to my question?
https is against the man in the middle, but with tomcat server, in this world, there is no service that you can avoid the man in the middle. It is not because technology does not allow, but the people in charge does not really understand the thing, so not able and not willing to provide the right service.
I want to ask: if you use tomcat server, is there any hosting service provider who does not act as a man in the middle? No. There is none on this world at present (May 2014)!

There is an apache reverse proxy located in front of your tomcat instance that does ssl termination. The Apache instance is at the node level, then tomcat runs on your gear.

is setting tomcat application url to http:// hostname/application/ possible?

I have a setup, with tomcat running on port 8080 and apache webserver running on port 80.
So if I access http://localhost:8080/myapplication/ , it works.
But I need to be able to make it like : http://localhost/application/, but since my http web server runs on port 80, it seems that i need some re-direction logic or changes at the tomcat to achieve this.
Can anyone please suggest i way out. Thanks.
UPDATE:
Just found that there is already a solution provided here: How do I redirect from Apache to Tomcat?
You need to look at the Tomcat-Apache HOWTO.
It is entirely possible and in fact quite common for apache and tomcat to be used in combination by the tactics described in this page.
And this question really probably belongs on serverfault...
Since you mentioned about "users", I am guessing you are implying "hostname", when you mention "localhost". If you have a Load Balancer and a user friendly DNS name that you would give to the users, you can configure your Load Balancer software to route all requests to "hostnameyougavetotheUsers" to "yourinternalhostname:8080".

How to bind an ip AND ports to subdomains using JBoss (Or Apache Tomcat)

This is my problem:
I have a JBoss server (Running an existing app) and a Apache Tomcat (Running an app created by me) server running on the same server with different ports.
I have two subdomain names which i have routed to the IP of the server.
What i need to do is to bind the subdomain names to the IP, but with different ports.
I saw an easy way to do it with XAMPP and apache, editing the httpd.conf, but i can't find any simular fway to do it with Apache Tomcat or JBoss.
Does anyone have any ideas about this?
I rather have a solution on the question above, but the question below can be accepted as a backup solution:
Since i could not figure that out, i had to at least have a solution to one of the applications (the one running at JBoss).
So i configured JBoss to port 80 instead of 8080.
What happens now if i go to the subdomains is that i get the JBoss welcome window.
How can i change the default JBoss "app" to my app?
Thanks in advance
There's no way to get this:
sub1.domain.com(192.168.0.1) on port 80 --> jboss app
sub2.domain.com(192.168.0.1) on port 80 --> tomcat app
without either adding to or subtracting from your software stack.
Your options are:
use jboss to run your tomcat app
add a reverse-proxy
use an HTTP-aware layer 7 firewall
The first is probably easiest; jboss deploys web applications using tomcat (or, in more recent versions, a fork of tomcat called jbossweb), so you can probably just drop your .war into the deploy directory.
If that's not possible for some reason, I'd use a reverse-proxy. Apache HTTPD with mod_proxy or mod_jk is fairly common. If you go the mod_jk route and you have non-trivial load, I'd review this.
The last I'm not familiar with. I imagine that the spendy Cisco firewalls can do this, and I'm sure it's possible to hack iptables to do it too, but my google-fu failed to find specifics.

Glassfish with Apache. Why SSL?

I have been looking around to figure out how to configure Glassfish front ended with Apache. And most of the tutorials using the load balancing plug in is making me enable SSL on Apache. I am trying to understand the connection. I should be able to do non SSL communications when I dont have a need for SSL.
There are several blog posts showing how you can use Apache in front of Glassfish. There are several options and depending on your needs, different strategies might be the most appropriate.
I've used Apache with mod_jk which forwards requests to Glassfish - both https and regular http. Lots of good references here.
It's possible to use other modules in Apache also like mod_proxy, but again the requirements you have will flesh out the most appropriate.
Glassfish also have pretty good http engine inside of it where you can configure virtual hosts like in apache. If the load on the Glassfish server isn't to big, you might consider just using Glassfish without anything in front of it.
You can also use the Sun Java System Web Server SJSWS instead of Apache. Despite it's atrocious name, it is just Sun's web server (free to use). It can be used as a reverse proxy (PDF). The SJWS/Glassfish combination is presumably tested really well by Sun.
