遇到的问题
- cassandra运行出现了Unable to gossip with any seeds，cqlsh链接不上,提示connection refused处理办法
出现这个问题的原因是cassandra.yaml配置文件的seeds 与 ip 设置错误
Check your cassandra.yaml and make sure that your "listen_address" and "seeds" values match, with the exception that the seeds value requires quotes around it.
请检查seeds 和 listen_address 是一致的。
另外，如果你采用了scutils方法设置了hostname， 那么请将seeds配置中的127.0.0.1改成你的hostname。
