Question

我有安装了CentOS 7的云端服务器。我昨天已经安装了Apache Cassandra 3.7。我昨天能够使用cqlsh访问Cassandra，但今天当我尝试使用cqlsh访问它时，它给出了如下错误：

块引用连接错误：（'无法连接到任何服务器'，{'127.0.0.1'：错误（111，“尝试连接到[（'127.0.0.1'，9042）]。上次错误：连接被拒绝”）}）块引用

下面是cassandra.log的详细信息

我还将listen_address和rpc_address更改为我的本地IP，public_ip和127.0.0.1但是没有连接

由于

Answer 1

我认为这是与用户persmission相关的错误。请尝试下面。它也可能是脚本冲突。

sudo chown -R cassandra:cassandra /var/lib/cassandra/data/test

OR

sudo chown -R cassandra:cassandra /var/lib/cassandra/data/


sudo chown -R cassandra:cassandra /var/lib/cassandra/commitlog.

任何方式都尝试以root身份启动cassandra

在关机之前，还要尝试正常关闭cassandra服务。

喜欢..

$ ps auwx | grep cassandra
$ sudo kill pid

OR

sudo service cassandra stop

Answer 2

非常感谢它只使用了 chown -R cassandra：cassandra / var / lib / cassandra / data /

卡桑德拉连接被拒绝
