Cassandra cqlsh无法连接到任何服务器 - 127.0.0.1:9160（关闭）>已经关闭 [英] Cassandra cqlsh Unable to connect to any servers - 127.0.0.1:9160 (closed)> is already closed

问题描述

我在OSX上安装了Cassandra。
当尝试从/ bin /运行cqlsh时，会出现以下错误：

I installed Cassandra on OSX. When trying to run cqlsh from /bin/, I get the following error:

> Connection error: ('Unable to connect to any servers', {'127.0.0.1':
> ConnectionShutdown('Connection <AsyncoreConnection(4522252560)
> 127.0.0.1:9160 (closed)> is already closed',)})

我安装Cassandra时遇到了问题， cassandra，从datastax安装了DSE，并从Apache下载了一个二进制文件。

I had difficulty installing Cassandra, and had used brew install cassandra, installed DSE from datastax, and downloaded a binary from Apache.

推荐答案

未正确卸载的安装。我的用户 .cassandra 目录有一些默认配置，必须是一个不同的版本，并阻止cqlsh启动。

I think the issue was the result of having a previous installation that wasn't properly uninstalled. My user .cassandra directory had some default configs, that must have been for a different version, and prevented cqlsh from starting.

rm -Rf ~/.cassandra

，我可以正确运行cqlsh。

After that, I could run cqlsh properly.

$ bin/cqlsh
