ubuntu - Cassandra 中的连接错误

Question

我在 ubuntu 16.04 上使用以下命令安装了 cassandra:

sudo apt-get install cassandra

它现在已安装，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)

我认为它与 3.0.8 版本正确安装。但是当我尝试运行时:

cqlsh

然后它显示以下错误:

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，任何形式的帮助都将不胜感激。提前致谢。

你检查过 netstat -ant监听 9042 端口的 IP 地址是什么？如果您关注 guidelines (快速入门应该足够了)然后尝试连接 cqlsh ipaddress .
