Hello there,

I have 2 web application on 2 different Tomcat machines with static IP and my clients connect to these application by entering the ip address of the servers to access the application. Please the the attached image to get a better idea. Now my problem is the clients need to enter the IP of the machine to access the web application, how can the client access the app using some domain name like, www.app1.com or www.app2.com on a local network. I will appreciate any help.

cheers

What you seem to be asking for, is someone to setup vanilla DNS for your two sites.

Simple searches will turn up many guides about how to do this + the summary is to setup two A records for the domains you mention above.

Likely you'll do this with your domain registrar, like GoDaddy or Namecheap.

Since this appears to be internal traffic, all that needs to be done is to create 2 A records on your internal DNS server.

If external access was involved, then registering a domain might become necessary. Whether you have an domain name to use already or end up registering one, A records would be necessary.

So no matter what, you need A records. Where you put them depends on whether the users are internal or external.

Thanks for your comments.

My setup is a private network, it will be accessed locally. I also dont have a DNS server in my network. Please give me suggestion on these.

if you dont have DNS in your network then you have to add manually in machines

rightlcik note pad Run as administrator browse c:\windows\System32\Drivers\Etc... folder

hosts  - open it

add as following Ex : (assume the ip for app1 192.168.1.7 and app2 as 192.168.1.78) replace ip's with your own...

192.168.1.7 app1.com
192.168.1.78 app2.com

and save it...

this is the one way...

the other way is install dns server on the web serve ... and add the DNS to all clients ..

if all devices using the same gateway ... in the lan then you can configure the DNS records point to the web servers ... or you can publish them from the router.

Hosts file would be your only solution. Since it's only two computers and a two entries for each, not a big deal. But if the network grows, recommend changing the strategy.

As masnrock said, use your /etc/hosts file for local network setup.

Problem is keeping /etc/hosts in sync across many machines, if required.

Far better to setup host records in real DNS for app1 + app2, so app1.foo.com + app2.foo.com so any client can connect + always get back the correct IP, even if that IP is a local 127.0.0.X IP which will make your management of IP resolution far simpler.
