aslo尝试运行cqlsh时出现以下错误
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(61, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})
我个人不知道为什么？我尝试了所有资源，但没有用任何人都可以帮助我]
问题是您很可能使用了不受支持的Java。您至少需要切换到Java 8 u151，但最好使用最新版本。
[此外，使用services确定Cassandra是否正在运行也不是可靠的检查方法。您应该运行nodetool status。干杯！
