How do I create a Mongo config file to allow access to http on port 28017 Well I want to configure the mongo server to allows access for http. 

I put this on my mongo config file:

port = 28017
rest = true


And when I restart my mongod service and try to access I got this message on the browser.


  It looks like you are trying to access MongoDB over HTTP on the native
  driver port.


I check my logs:

cat /log/mongod.log

I refresh the browser and the logs show me that:

2015-08-07T18:24:09.246+0000 [initandlisten] connection accepted from 181.196.26.130:64683 #24 (1 connection now open)

2015-08-07T18:24:09.493+0000 [conn25] end connection IPAddress:53343 (0 connections now open)


So If the log says that it waiting for connection on that port give me a respond but I can't see the http admin view, any idea or tips?
You're on RHEL6 or a derivative from your kernel version 2.6.32-431.3.1.el6.x86_64. The default firewall only allows ssh incoming. You'll need to poke a hole in your firewall. Look here for firewall tips:
