Question

我在ubuntu 16.04上使用以下命令安装了cassandra：

sudo apt-get install cassandra

现在安装，当我运行命令时：

sudo service cassandra status

它显示如下：

● cassandra.service - LSB: distributed storage system for structured data
  Loaded: loaded (/etc/init.d/cassandra; bad; vendor preset: enabled)
Active: active (exited) since Wed 2016-09-14 17:01:17 IST; 11min ago

lines 1-10/10 (END)

我认为它已在3.0.8版本中正确安装。但是当我试图跑：

cqlsh

然后显示以下错误：

Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(111, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})

我不知道为什么会这样，任何形式的帮助都会受到赞赏。提前致谢。

Answer 1

您是否使用netstat -ant检查了侦听端口9042的IP地址是什么？如果您按照guidelines（快速入门应该足够），请尝试与cqlsh ipaddress建立联系。
