bad_header用于将sensu客户端连接到服务器时进行AMQP连接

Question

I have installed sensu with chef community cookbook. However, sensu client fails to connect to server. Results in rabbitmq connection error with message timed out while attempting to connect

Here are detailed client logs

logs from sensu-client.log

"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"]}}

Rabbitmq logs from server show following error

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

=ERROR REPORT==== 8-Jul-2014::12:39:54 ===

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

I am running this on CentOS 6.4 on AWS Rabbitmq version 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 suggests mismatch for client and broker AMQP version. Any help for finding out AMQP version and fixing this problem

在我的情况下，此问题是由于将客户端配置为使用ssl身份验证而引起的，但是Rabbitmq服务器未正确配置为使用ssl，而是期望“普通”用户/密码登录而没有ssl。
