Page Comparison

This page lists the tasks/steps you need to do when you want to change your domain e.g. from the default 'nmsprime.test' domain to your own publicly reachable domain name and your system is already a production environment with a lot of devices monitored by icinga and cacti.

The examples show a domain change from nmsprime.test to nmsprime.your-domain.com.

4) Step 1 changes the FQDN of the server. As icinga refers to the internal server hostname and it is not needed anywhere else, we change it back.

Code Block

language	bash

hostnamectl set-hostname server-name.nmsprime.test

5) Synchronize the nameserver

Code Block

language	bash
title	Synchronize named

# Sync zone files
rndc sync -clean && systemctl stop named

# Adapt names
mv /var/named/dynamic/nmsprime.test.zone /var/named/dynamic/nmsprime.zone
sed -i 's/nmsprime.test/nmsprime.your-domain.com/g' /var/named/dynamic/in-addr.arpa.zone
sed -i 's/nmsprime.test.zone/nmsprime.zone/' /etc/named-nmsprime.conf
sed -i 's/zone "nmsprime.test"/zone "nmsprime.your-domain.com"/' /etc/named-nmsprime.conf

systemctl start named

sed -i 's/cpe.nmsprime.test/cpe.nmsprime.your-domain.com/' /etc/named-ddns.sh

6) Cacti Adaptions

Code Block

language	bash

# Get cacti password
grep "CACTI_DB_PASSWORD" /etc/nmsprime/env/provmon.env

# Change DB entries
mysql -u cactiuser -pIejeequ6oapa cacti
UPDATE host set hostname=REPLACE(hostname, '.test', '.your-domain.com') where hostname like 'cm-%nmsprime.test%';
UPDATE data_input_data set value=REPLACE(value, '.test', '.your-domain.com') where value like '%cm-%nmsprime.test%';
UPDATE poller_item set arg1=REPLACE(arg1, '.test', '.your-domain.com') where arg1 like '%cm-%nmsprime.test%';
quit
