##

Requirements:

php5
mysql server
php-mysql support
perl 5.6 or higher


apt-get install mysql-server php5 php5-mysql

you will be prompted for a password
use 'nconf' as root password for mysql
######Create a database/username/password to use for nconf######

mysql -u root -p
CREATE DATABASE nconf;
CREATE USER 'nconf'@'localhost' IDENTIFIED BY 'k3n3t';
GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, ALTER ON nconf.* TO 'nconf'@'localhost' IDENTIFIED BY 'k3n3t';
flush privileges;
#######################

############change to tmp directory######

# cd /tmp
#######Download nconf.tgz######

wget http://downloads.sourceforge.net/project/nconf/nconf/1.3.0-0/nconf-1.3.0-0.tgz

########Extract the download to /var/www directory######

tar xzvf nconf-1.3.0-0.tgz -C /var/www

#### change direcory owner to www-data(Apache user)#######

chown -R www-data:www-data /var/www/nconf



Now browse http://VMX.ws.nsrc.org/nconf

Follow steps to install nconf

###set below database parameters####
D
BHOST:localhost
DBNAME:nconf
DBUSER:nconf_admin
DBPASS:"nconf user mysql password"

Use everything else as default except NAGIOS_BIN variable to /usr/sbin/nagios3


at the end it will ask you to delete following files and directories

cd /var/www/nconf

rm -rf INSTALL INSTALL.php UPDATE UPDATE.php

####NAGIOS CONFIGURATION#######
######create nagios directories where nconf will copy the config files######
mkdir /etc/nagios3/global
mkdir /etc/nagios3/Default_collector
##change directory permissions

chown -R www-data:www-data /etc/nagios3/global
chown -R www-data:www-data /etc/nagios3/Default_collector


Now its time to configure nagios for nconf

Open /etc/nagios3/nagios.cfg
comment out all the lines that begin with cfg_dir= or cfg_file=
Add following 2 lines and save file

cfg_dir=/etc/nagios3/global
cfg_dir=/etc/nagios3/Default_collector

##comment out below parameters in nagios.cfg

cfg_file=/etc/nagios3/commands.cfg
cfg_dir=/etc/nagios-plugins/config
cfg_dir=/etc/nagios3/conf.d



At this point you should be able to add hosts and configure services on nagios using Nconf,however nconf will not be able to restart the nagios service until
we assign www-data(Apache user) permission to execute the nagios service init script.

####Assigning permissions to www-data user

This is done in the sudoers file.
Run the below command to open and edit the file 

#visudo

add the below line just below     root  ALL=(ALL:ALL) ALL

www-data ALL = NOPASSWD: /etc/init.d/nagios3 reload

Now login to the nconf web UI and add a host/Add 2 the previous host from the nagios Lab

###Edit nconf deployment.ini file and uncomment the below lines by removing the preceeding semi colons###

nano /var/www/nconf/config/deployment.ini

[extract config]
type        = local
source_file = "/var/www/nconf/output/NagiosConfig.tgz"
target_file = "/tmp/"
action      = extract

[copy collector config]
type        = local
source_file = "/tmp/Default_collector/"
target_file = "/etc/nagios3/Default_collector/"
action      = copy

[copy global config]
type        = local
source_file = "/tmp/global/"
target_file = "/etc/nagios3/global/"
action      = copy
reload_command = "sudo /etc/init.d/nagios3 reload" (add this line at the end of this column)


Ensure you change the target_file to /etc/nagios3 from /etc/nagios
