连接到Google Cloud Compute上的cassandra

Question

我通过他们的发射器：https://cloud.google.com/launcher/explore?q=cassandra部署了一个Cassandra集群

我可以通过SSH/PuTTY连接到VM精细。

然后，当我试图连接例如DBeaver时，我得到：

com.datastax.driver.core.exceptions.NoHostAvailableExeption: All host(s) tried for query failed(tried: /x.x.x.x:9160) com.datastax.driver.core.ConnectionExption:[/x.x.x.x:9160] Unexpected error during transport initialization. Connection has been closed

或者使用cassandra-driver (nodejs)，我得到：

All host(s) tried for query failed. First host tried, x.x.x.x:9160: Error: read ECONNRESET. See innerErrors. InnerErrors: { 'x.x.x.x:9160': { [Error: read ECONNRESET] code: 'ECONNRESET', errno: 'ECONNRESET', syscall: 'read' } } Info: Represents an error when a query cannot be performed because no host is available or could be reached by the driver.

我在google控制台中转发了9160端口，它似乎可以工作，因为当我停止VM上的cassandra服务器时，它会产生一个不同的错误，表明连接被拒绝：

All host(s) tried for query failed. First host tried, x.x.x.x:9160: Error: connect ECONNREFUSED. See innerErrors. InnerErrors: { 'x.x.x.x:9160': { [Error: connect ECONNREFUSED] code: 'ECONNREFUSED', errno: 'ECONNREFUSED', syscall: 'connect' } } Info: Represents an error when a query cannot be performed because no host is available or could be reached by the driver.

现在，我尝试将cassandra.yaml rcp_adress编辑到实际的external地址，而不是0.0.0.0。我还尝试过internal服务器场地址。

我没有更改默认身份验证(但也尝试使用auth)：

authenticator: AllowAllAuthenticator
# authenticator: PasswordAuthenticator

authorizer: AllowAllAuthorizer
# authorizer: CassandraAuthorizer

我不知所措，连接似乎有效，但cassandra似乎不允许登录或重置连接？

您正在尝试连接到节俭端口(9160)。您应该使用本机协议端口(9042)。
