cassandra节点发现 [英] cassandra node discovery

问题描述

我刚刚设置了一个IP地址为192.168.0.101，192.168.0.102，192.168.0.103的3节点系统。我已经将所有三台机器配置的种子值设置为
seeds：192.168.0.101,192.168.0.102,192.168.0.103

I just set up a 3 node system with ip addresses "192.168.0.101", "192.168.0.102", "192.168.0.103". I have set the seeds value on the configuration of all three machines as seeds: "192.168.0.101,192.168.0.102,192.168.0.103"

但是，在运行nodetool时，只有 103 机器被发现。

However, on running nodetool on any of them, only the 103 machine gets discovered.

有人可以告诉我问题出在哪里？

Could someone tell me where the problem lies?

推荐答案

/ p>

I would recommend

1. 确保您使用的是Cassandra的最新稳定版本


2. 在所有机器上执行种子（例如：.101）



3. 将它添加到log4j-server.properties：

1. Make sure you're on the latest stable release of Cassandra
2. Start with a single node as seed on all machines (say, .101)

3. Add this to log4j-server.properties:

log4j。 logger.org.apache.cassandra.gms = TRACE

log4j.logger.org.apache.cassandra.gms=TRACE
