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.


Preparation

  • Add the domain / subdomain
  • Add the NS Record for NMSPrime name server at your provider


Change Domain globally

Code Block
languagebash
# Check your NMSPrime server's hostname as we want to change the internal FQDN (fully qualified domain name) back later
hostnamectl


Navigate to Global Configuration → Provisioning and change the default domain to your domain e.g. nmsprime.your-domain.com

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


Code Block
languagebash
hostnamectl set-hostname server-name.nmsprime.test


Adapt name server configuration

Code Block
languagebash
titleSynchronize 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


Cacti

Code Block
languagebash
# 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


Firewall

Code Block
languagebash
# Add DNS Service to firewall
firewall-cmd --add-service=dns --zone=public
firewall-cmd --add-service=dns --zone=public --permanent
