Nagios is using your apache installation.
You should change the Apache config for that.

can you please let me know how to change as my apache is running in default configuration

https://httpd.apache.org/docs/2.4/bind.html

[harsha.s.aryan]

is it possible to to like below

default URL http://localhost/nagios

I am looking like http://localhost/8081

instead of giving /nagios I want to give port number to access nagios

[rhassing]

This should be possible, please search for the apache config posibilities.

Do you mean http://localhost:8081 or did you intend on http://localhost/8081?

What OS are you running? Is there a specific reason you'd like to change the port?

I am look for http://localhost:8081 this and I am using Ubuntu 14

I believe there are 3 places you will need to change (this is for a RHEL box - the directories may be somewhat different on Ubuntu) -

File - /etc/httpd/conf/httpd.conf
Look for Listen 80 change to Listen 8081

File - /usr/local/nagiosxi/html/config.inc.php
Look for $cfg['port_number'] = 80; change to $cfg['port_number'] = 8081;

Admin > System Config > Manage System Config
- Change Program URL and External URL (if you have it set) to include the port.
