Integrating new pollers in a Centreon-HA cluster
Obtaining central nodes' thumbprints
Both central nodes' Gorgone services will need to be authorized by the pollers' Gorgone services.
- First, let's get each central node's key:
wget -O /root/gorgone_key_thumbprint.pl https://raw.githubusercontent.com/centreon/centreon-gorgone/master/contrib/gorgone_key_thumbprint.pl
perl /root/gorgone_key_thumbprint.pl --key-path /var/lib/centreon-gorgone/.keys/rsakey.priv.pem
The command output should look like:
2020-09-25 10:47:35 - INFO - File '/var/lib/centreon-gorgone/.keys/rsakey.priv.pem' JWK thumbprint: RsfNibuDdOvzwP75G72rpIKIG2nRhkyGQrQXE4pXa_s
- You must have two keys, one for each central node. Copy the last part of the printed lines (what is displayed after
JWK thumbprint:) and keep it for later.
Adding the Poller to configuration
Add your poller to the configuration "the standard way" following these steps with ZeroMQ protocol
You should now have overwritten the
/etc/centreon-gorgone/config.d/40-gorgoned.yamlfile, and it should contain such lines:
- key: tRsFMBv9X3ScNFMwvG8D652nXMsgEYMb1qsJek-Mns8
Configuring Gorgone on the poller
- You now have to modify
/etc/centreon-gorgone/config.d/40-gorgoned.yamlon the poller in order to have both central keys in this section:
- key: key_1_from_earlier
- key: key_2_from_earlier
- Now restart Gorgone on the poller:
systemctl restart gorgoned
At this point any of your central nodes should be allowed to connect to your poller's Gorgone service and send configuration, retrieve statistics, restart services, ...
