New NLS node errors out when trying to add to cluster
New NLS node errors out when trying to add to cluster
I keep getting this error message on this page: (http://newlogserver.com/nagioslogserver ... hp/install)
"Could not establish connection, this could be due to a slow connection, or you may want to re-enter your cluster information." After entering in our existing Hostname and Cluster ID on our new node.
Why would it be giving me this error message when both firewalls are off?
How do I connect this new server to my current cluster for redundancy?
I can ping our current NLS with the new one from the terminal.
They are both installed on CentOS 7 machines and are both on the same network.
I can ensure that the *Cluster ID and **Hostname are correct.

In the 'Hostname' field, try using the IP address of a current node in the NLS cluster. Please let us know the result. Thanks!

Can the new CentOS7 server ping 10.30.216.88 ? And vice versa?

Yes I can ping each other from both of them using IP and hostname.

Please run the following command on your existing cluster, and return the results to us:
I want to verify that the clusterID matches the picture you have displayed.
Are you certain that both firewalld and iptables are off?
Code: Select all
cat /usr/local/nagioslogserver/var/cluster_uuidAre you certain that both firewalld and iptables are off?
Code: Select all
systemctl stop firewalld
systemctl stop iptablesRe: New NLS node errors out when trying to add to cluster
Ok...
Both firewalld's are stopped.
I tried to enter in the hostname/ip and cluster id again and it did not work.
[owen@radium ~]$ cat /usr/local/nagioslogserver/var/cluster_uuid

Re: New NLS node errors out when trying to add to cluster
In the host name field on the server you are trying to add to the cluster, try putting it's own name in it instead of the current server's ip or host name.
