Question

我在Ubuntu 13上安装了新的EC2（在AWS上），并准备好运行我的服务器的所有环境。

当我用：

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。我环顾四周试试他们说的话，Cassandra正常运行，看看提示：

我查看了system.log，但我没有看到任何错误：

如何像普通服务一样运行Cassandra？

Answer 1

只需使用/bin/cassandra

即可

这将运行cassandra作为后台服务/守护程序

Answer 2

您可以使用“SupervisorD”将cassandra作为服务运行：

Cassandra无法在/etc/init.d/cassandra启动时作为服务运行
