In
my previous post, I explained how to map localhost to a domain. In this post, I
am going to explain, how to map localhost:port to a domain.
When
user hit the URL in browser, browser establish connection with web server in
the port 80 by default in case of HTTP, 443 by default in case of HTTPS.
By
running the application server instance on port 80, we can access the
application by domain name (we can exclude port number).
I
am going to show you, how to run the application on localhost (excluding port
number), followed by running the application using domain name.
Running application
on localhost (Excluding port)
It
is very simple, make sure your application server runs on port 80.
For
example, by default tomcat runs on port 8080. In eclipse, you can see the
configuration of tomcat by double clicking it.
Change
the port number from 8080 to 80.
Run
the application on server.
Map localhost to
domain
By
modifying local dns settings, we can point the localhost (or) 127.0.0.1 to some
domain name.
We
need to modify the hosts file.

Operating system
|
Host file location
|
|
UNIX
|
/etc/hosts
|
|
Windows
|
C:\Windows\System32\drivers\etc\hosts
|
I
am going to show the demo in windows operating system, procedure is same for
UNIX.
Now
open hosts file and add below statement to it.
127.0.0.1
myexample.com
You
can access the application using domain name. See the below screenshot.
