Hello, I encountered some issues while trying to use Eventstore.
Here is my configuration↓

My first question is, why are there three additional nodes, and why are they associated with external IP addresses?

Then I tried to modify the configuration file to set the external IP as the external IP and the internal IP as the internal IP.

The error is as follows:

My external IP is fine, and the ports are also open, So, any suggestions? What should I do?

I am using the latest version 24.2

2

What are the ip adresses ( A records ) in the cluster DNS addrress ?

4

I believe Yves asked about what that blurred DNS name specified in ClusterDns resolves to.

6

If you use that cluster DNS name, the NodeIp needs to be set to those public addresses, not internal addresses. Replication IP is good.

I set it up as you said. the error will be like this↓

One of my configration like this

---
# Paths
Db: /var/lib/eventstore
Index: /var/lib/eventstore/index
Log: /var/log/eventstore

# Certificates configuration
CertificateFile: /etc/eventstore/certs/node.crt
CertificatePrivateKeyFile: /etc/eventstore/certs/node.key
TrustedRootCertificatesPath: /etc/eventstore/certs/ca

# Network configuration
ReplicationIp: 10.0.2.4
NodeIp: 3x.2xx.1xx.x
HttpPort: 2113
IntTcpPort: 1112
EnableAtomPubOverHTTP: true
Insecure: true

# Cluster gossip
ClusterSize: 3
DiscoverViaDns: true
ClusterDns: public.dns.com

# Projections configuration
RunProjections: All

And i could see the error in error log like i said before.

you need to add AdvertiseHostToClientAs: [node DNS name] to the config of each node

  • in term of DNS

    • you also need an A record per node, with the IP address of the node

  • in term of Certificates make sure the cert includes

    • the dns name of the nodes as SAN
      alternatively
    • usa a wildcard cert

this article should help you with the complete setup
( some settings name have changed)

Thank you for your answers. With reference to the documentation, I am now able to read and write using the client. However, I am unsure if the appearance of ‘unknown’ here is normal. The cluster I have set up consists of 3 nodes.

@wangziyejimo i haven’t forgotten about this, I’ll hae a look tommorrow .
( sorry been busy a lot)
