Question

我已经在Ubuntu 18.04.2 LTS上设置了Apache pulsar独立v2.3 来自Run Pulsar locally。无需任何身份验证即可正常工作。我尝试使用security-tls-transport和security-tls-authentication配置tls证书。我已经按照链接中所述修改了以下配置broker.conf，client.conf和standalone.conf。使用命令bin/pulsar standalone运行脉冲星，并使用下面的命令发送消息。

bin/pulsar-client produce my-topic --messages "hello-pulsar"

但是会引发以下错误

任何人都可以帮助解决此问题吗？

Answer 1

启用TLS传输加密后，您需要将客户端配置为对Web服务URL使用https：//和端口8443，对代理服务URL使用pulsar + ssl：//和端口6651。

您使用的客户端CLI工具看起来像bin / pulsar-client产生了my-topic --messages“ hello-pulsar”，没有使用https + ssl：//前缀。因此，您的客户端正在尝试建立不安全的连接，并且由于它而导致TLS协商步骤失败。

您可以尝试使用指定了pulsar + ssl：//前缀的简单Java或Python客户端进行连接吗？

Answer 2

如果已在broker.conf，client.conf和standalone.conf中进行了所有必需的更改，请尝试运行以下命令来发布数据：

bin/pulsar-client --url pulsar+ssl://127.0.0.1:6651 produce my-topic --messages "hello-pulsar"

在这里，您需要指定tls数据的服务网址。

确保已将以下属性添加到standalone.conf文件中：

tlsEnabled=true
tlsCertificateFilePath=/path/to/broker.cert.pem
tlsKeyFilePath=/path/to/broker.key-pk8.pem
tlsTrustCertsFilePath=/path/to/ca.cert.pem
brokerServicePortTls=6651

此外，请确保您更新client.conf文件中的以下配置值：

brokerServiceUrl=pulsar+ssl://127.0.0.1:6651
webServiceUrl=https://127.0.0.1:8443
tlsTrustCertsFilePath=/path/to/ca.cert.pem

这应该有效。
