将 sensu-client 连接到服务器时用于 AMQP 连接的 bad_header

Question

我已经安装了带有厨师社区食谱的 sensu。但是，sensu 客户端无法连接到服务器。尝试连接时导致rabbitmq连接错误，消息超时

这里是详细的客户端日志

来自 sensu-client.log 的日志

"timestamp":"2014-07-08T12:39:33.982647+0000","level":"warn","message":"config file applied changes","config_file":"/etc/sensu/conf.d/config.json","changes":{"rabbitmq":{"heartbeat":[null,20]},"client":[null,{"name":"girija-sensu-client","address":"test sensu client","subscriptions":["test-node"]}],"version":[null,"0.12.6-4"]}}

来自服务器的 Rabbitmq 日志显示以下错误

=INFO REPORT==== 8-Jul-2014::12:39:54 ===
accepting AMQP connection <0.395.0> (10.254.153.131:42813 -> 10.254.130.25:5672)

{bad_header,<<129,15,1,3,3,0,246,0>>}

我在 AWS 上的 CentOS 6.4 上运行它 Rabbitmq 版本 3.0.4 Erlang_version, "Erlang R14B04 (erts-5.8.5) [source] [64-bit] [rq:1] [async-threads:30] [kernel-poll:true]\n"},

bad_header 建议客户端和代理 AMQP 版本不匹配。查找 AMQP 版本和解决此问题的任何帮助

在我的情况下，当我的客户端配置为使用 ssl 身份验证，但 rabbitmq 服务器未正确配置为使用 ssl 而是期望“普通”用户/密码登录时没有 ssl 时，就会导致此问题。
