无法启动Cassandra服务 [英] Can't able to start Cassandra Services

问题描述

我刚刚下载tar球并解压缩。我已完成的步骤位于此问题

I just downloaded tar ball and extracted it. Steps i have done is in this question

path/dse/bin/cassandra-cli

它说连接在端口9160拒绝

It says Connection refused at port 9160

netstat -plten

在9160上没有返回任何进程。因此，cassandra服务未启动。如何开始呢？我需要设置任何env变量或配置更改？我正在设置单节点设置。

returns no process on 9160. So cassandra service is not started. How to start it? DO i need to set any env variables or config changes? I am setting up just single node setup.

Exception connecting to 127.0.0.1/9160. Reason: Connection refused.
Welcome to Cassandra CLI version 1.1.9-dse-2.2.2-SNAPSHOT

帮助？

推荐答案

您要运行 /< dse目录> / bin / dse cassandra 在 tarball安装或 service dse start 在软件包安装上启动DSE。只有当DSE服务正在运行时，才能连接到它。检查它是否正在运行 ps -ef | grep dse

You want to run /<dse directory>/bin/dse cassandra on a tarball install or service dse start on a package install to start DSE. Only when the DSE service is running can you connect to it. Check if it's running with ps -ef|grep dse

顺便说一下，注意cassandra-cli已弃用。请改用 cqlsh ！

By the way, note that cassandra-cli is deprecated. Use cqlsh instead!
