卡桑德拉（Cassandra）无法八卦

Question

At first I downloaded Cassandra 3.7 and installed it on a remote machine (still in the same network) But I wanted to run this as a service so I downloaded and installed the DataStax_DDC_Server 3.7.0

But when I try to connect remotely to the service I get the error: Unable to gossip with any seeds So i followed a couple solutions to that problem.

Cassandra Cluster Set up - Unable to gossip with any seeds Apache Cassandra: Unable to gossip with any seeds

I don't think its a firewall or port problem, since I could connect to the other Cassandra database. I also copied the .YAML files from the old Cassandra environment (the one that was working)

What else can I try? Do I have to change more things in the .yaml file in the datastax version instead of the version directly downloaded from http://cassandra.apache.org/download/ ?

Could it be the datastax version uses other ports?

EDIT: It works locally. Also, when i remove the datastax version my old Cassandra environment also works again, but it needs to be a service so I cannot use that environment since it doesn't include a service.

EDIT2: uploaded cassandra.yaml https://www.dropbox.com/sh/wuhwc31oyztotzm/AAC0x9PcH7dIjZszpxRvDNjba?dl=0

Answer 1

To join new node in cluster you should change cassandra.yaml of that one:

1. Specify cluster name (should be the same for all cluster nodes):

   cluster_name: 'MyCluster'

2. Specify seed nodes of cluster (on seed node this own ip or/and other seeds):

seed_provider:
- class_name: org.apache.cassandra.locator.SimpleSeedProvider parameters:
- seeds: "seed ip1, seed ip2"

This is main settings for Cassandra cluster
