Rename semua file tersebut misal cgi.cfg-sample mennjadi cgi.cfg
5. Modif file cgi.cfg, seperti berikut ini
# AUTHENTICATION USAGE
# This option controls whether or not the CGIs will use any
# authentication when displaying host and service information, as
# well as committing commands to Nagios for processing.
#
# Read the HTML documentation to learn how the authorization works!
#
# NOTE: It is a really *bad* idea to disable authorization, unless
# you plan on removing the command CGI (cmd.cgi)! Failure to do
# so will leave you wide open to kiddies messing with Nagios and
# possibly hitting you with a denial of service attack by filling up
# your drive by continuously writing to your command file!
#
# Setting this value to 0 will cause the CGIs to *not* use
# authentication (bad idea), while any other value will make them
# use the authentication functions (the default).use_authentication=0
Ubah nilai default otentikasi menjadi 0, agar anonymous user bias mengakses aplikasi, Nilai 1 memaksa user melakukan otentikasi sebelum melihat aplikasi.
6. Modif file nagios.cfg
# Command definitions
cfg_file=/usr/local/etc/nagios/commands.cfg# Host and service definitions for monitoring this machine
cfg_file=/usr/local/etc/nagios/localhost.cfgbuka tanda pagar untuk localhost.cfg dan commands.cfg
7. Modif. File localhost.cfg, server saya kira-kira seperti ini
###########################################################
# LOCALHOST.CFG – SAMPLE OBJECT CONFIG FILE FOR MONITORING THIS MACHINE
#
# Last Modified: 11-27-2006
# By Gigih Forda Nama
# NOTE: This config file is intended to servce as an *extremely* simple
# example of how you can create your object configuration file(s).

8. Tambahkan option startup pada /etc/rc.conf
nagios_enable=”YES”
9. Jalankan Program nagios dengan mengetikkan command berikut
unila-inherent-gtw# /usr/local/etc/rc.d/nagios start
nagios already running? (pid=89792).
unila-inherent-gtw#
10.
11. Tambahkan skrip berikut di /usr/local/etc/apache22/extra/httpd-vhosts.conf
<VirtualHost *:80>
ServerAdmin // <![CDATA[var prefix = 'ma' + 'il' + 'to';
var path = 'hr' + 'ef' + '=';
