我在 Ubuntu 13 上安装了一个新的 EC2（在 AWS 上），并准备好所有环境来运行我的服务器。
当我运行 Cassandra 时：
/bin/cassandra -f
一切顺利。我可以使用命令成功连接 cassandra-cli
cassandra-cli -host localhost -port 8070
但是当我关闭 Cassandra 并作为服务运行时
/etc/init.d/cassandra start
同样的 cassandra-cli 没有回答。我环顾四周，试了一下他们说的，Cassandra 运行正常，看看是什么提示：
root@ip-10-252-42-119:/bin# ps ax|grep cassandra

我查看了 system.log，但没有发现任何问题：

我该怎么做才能像正常服务一样运行 Cassandra？
