Couchbase 与 Azure Linux 虚拟机
Couchbase with Azure Linux VM
我在 Azure 上安装了 ubuntu 服务器 VM 我安装了 couchbase 社区版现在我需要使用 dotnet SDK 访问 couchbase 但代码显示 未找到或无法访问存储桶 错误。
即使我尝试配置 public dns 并在集群创建期间将其作为 ip 提供，但它仍然提供相同的信息。
甚至我在主机文件中添加了 public dns，如下所示
127.0.0.1 public DNS
SDK 日志包括以下 2 个语句
尝试在端点“name.eastus.cloudapp.azure.com”上引导失败。 (e80489ed)
连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立连接失败，因为连接的主机没有响应。

谢谢！！
感谢您提供如此详细的信息！我怀疑眼前的问题是您正在尝试使用 TLS 进行连接，Couchbase Community Edition 不支持它（至少从 2022 年 2 月开始不支持）。端口 11207 和 18091 用于 TLS 连接；正如您在 lsof 输出中观察到的那样，服务器没有侦听这些端口。
我通过更改 couchbase 的连接字符串解决了这个问题
来自
couchbase://
至
http://
我在 Azure 上安装了 ubuntu 服务器 VM 我安装了 couchbase 社区版现在我需要使用 dotnet SDK 访问 couchbase 但代码显示 未找到或无法访问存储桶 错误。 即使我尝试配置 public dns 并在集群创建期间将其作为 ip 提供，但它仍然提供相同的信息。 甚至我在主机文件中添加了 public dns，如下所示 127.0.0.1 public DNS SDK 日志包括以下 2 个语句 尝试在端点“name.eastus.cloudapp.azure.com”上引导失败。 (e80489ed) 连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立连接失败，因为连接的主机没有响应。

谢谢！！
感谢您提供如此详细的信息！我怀疑眼前的问题是您正在尝试使用 TLS 进行连接，Couchbase Community Edition 不支持它（至少从 2022 年 2 月开始不支持）。端口 11207 和 18091 用于 TLS 连接；正如您在 lsof 输出中观察到的那样，服务器没有侦听这些端口。
我通过更改 couchbase 的连接字符串解决了这个问题
