Question

在OpsCentre无法正常工作的两种情况下，我在Windows 7的两台不同计算机上遇到Datastax Community Edition（datastax-community-64bit_1.2.6.msi）错误。这是在安装后立即执行的，除了按照安装向导之外我没有做任何其他事情。 OpsCenter在浏览器中完成加载后弹出以下错误（“localhost：88888”）：

“加载事件时出错：ClusterServices实例没有属性 'event_store'“

为了给出一些上下文我想使用Cassandra后端开发一个ASP.NET MVC应用程序，并试图用[Chirper .NET app] [1]作为例子来掌握它。

非常感谢， ħ

Answer 1

这是问题所在：

尝试以其权限禁止的方式访问套接字

我对Windows不是很熟悉，所以我不确定是什么原因造成的。防火墙吗？没有以管理员身份运行？

Answer 2

假设它仍然是错误10013，这通常意味着防火墙/防病毒软件禁止访问。你可以暂时禁用它吗？您可能需要检查防火墙/防病毒日志以查看是否允许访问OpsCenter（这比打开机器的风险要小）。您可能还需要为Cassandra打开端口（请参阅此处：Cassandra port usage - how are the ports used?）。
