【发布时间】：2021-03-09 18:04:28
【问题描述】：

当我运行 cassandra 时，我得到如下输出：

D:\STUDIA\cassandra\apache-cassandra-3.11.9\bin>cassandra
Detected powershell execution permissions.  Running with enhanced startup scripts.
*---------------------------------------------------------------------*
*---------------------------------------------------------------------*

    WARNING!  Automatic page file configuration detected.
    It is recommended that you disable swap when running Cassandra
    for performance and stability reasons.

*---------------------------------------------------------------------*
*---------------------------------------------------------------------*
Failed 64-bit check. Re-running to get version from 32-bit
*---------------------------------------------------------------------*
*---------------------------------------------------------------------*

    WARNING! Detected a power profile other than High Performance.
    Performance of this node will suffer.
    Modify conf\cassandra.env.ps1 to suppress this warning.

*---------------------------------------------------------------------*
*---------------------------------------------------------------------*
Cassandra 3.0 and later require Java 8u40 or later.

当我输入 cqlsh 时：

D:\STUDIA\cassandra\apache-cassandra-3.11.9\bin>cqlsh
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(10061, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Nie mo\xbfna nawi\xb9za\xe6 po\xb3\xb9czenia, poniewa\xbf komputer docelowy aktywnie go odmawia")})

它说 “不能建立连接，因为目标计算机正在积极拒绝它”

【解决方案1】：

错误表明 Cassandra 没有运行。您需要检查 Cassandra system.log 以了解原因。

它可能无法启动或关闭。不查看日志就不可能知道原因。干杯！

我更改了 jdk 版本并开始了一些东西，但我现在用 cassandra 得到了这些错误
