我已成功安装ccm并创建了测试集群

ccm list
 *tutorial
ccm status
node1: DOWN (Not initialized)

node1:DOWN异常: 我还是尝试过

ccm start

我通读了这篇文章post.但并不完全清楚什么需要成为节点:

有两件事需要考虑:

1. CCM 将自动启动 cassandra 实例。所以你不必自己做。如果您已经启动它，请使用kill PID(PID是进程ID，您可以通过在POSIX机器上的命令行中输入ps aux | grep cassandra来获取)

2. 您必须设置CASSANDRA_HOME。 这就是我的 .bash_profile 的样子。您可以输入 .bashrc 或 .bash_profile。但是source它以将其设置为当前环境

   导出 CASSANDRA_HOME=/Users/Documents/cassandra
