卡桑德拉可以'；t使用/etc/init.d/cassandra start作为服务运行

我用Ubuntu13安装了一个新的EC2（在AWS上），并准备好运行我的服务器的所有环境

当我运行Cassandra时：

  /bin/cassandra -f 

一切顺利。我可以使用以下命令成功连接cassandra cli

cassandra-cli -host localhost -port 8070

但是当我关上卡桑德拉，作为一个服务运行时

 /etc/init.d/cassandra start 

同样的cassandra cli无法回答。我环顾四周，尝试他们所说的，卡桑德拉正在正常运行，看到什么提示：

我该怎么做才能像正常服务一样运行Cassandra？

只需使用

/bin/Cassandra

这会将cassandra作为后台服务运行/deamon

您可以使用“SupervisorD”将cassandra作为服务运行：

要将cassandra作为服务运行，请使用

/bin/cassandra

而不使用-f标志。您是否尝试过

cassandra cli-host`hostname`-端口8070

？另外，尝试只使用

cassandracli-host`hostname`

。但是，如果在前台模式下连接，它没有理由不连接到服务。Lyuben Todorov，谢谢你的帮助。如果其他人有这些问题，请尝试使用debian，因为Ubuntu似乎有很多Java问题。我确实在Ubuntu上实现了这一点，尽管这是一个痛苦的过程（我甚至不确定了），但我现在使用debian for Cassandra，它可以直接工作，不需要大惊小怪。
