我一直在尝试安装Sensu，我一直在遵循安装指南，安装时一切顺利，但是当我从文档中添加示例检查时，Sensu 突然无法连接到 RabbitMQ。具体来说，当我添加check_cron.json配置时。我尝试重新启动并删除配置（然后再次重新启动），但 Sensu 一直超时。值得注意的是，RabbitMQ 已安装并正在运行，甚至可以通过管理界面导航，但 Sensu 似乎没有意识到这一点。

以下是我的服务器日志：

如果您在 rabbitmq 服务器上使用 ssl 证书，那么您的证书可能有问题。github上有一个脚本克隆它并运行以下命令：

git clone git://github.com/joemiller/joemiller.me-intro-to-sensu.git
cd joemiller.me-intro-to-sensu/

./ssl_certs.sh clean
./ssl_certs.sh generate

然后配置 Rabbitmq 以使用这些证书：

mkdir /etc/rabbitmq/ssl
cp server_key.pem /etc/rabbitmq/ssl/
cp server_cert.pem /etc/rabbitmq/ssl/
cp testca/cacert.pem /etc/rabbitmq/ssl/

并将此配置添加到 /etc/rabbitmq/rabbitmq.config：

[
  {rabbit, [
    {ssl_listeners, [5671]},
    {ssl_options, [{cacertfile,"/etc/rabbitmq/ssl/cacert.pem"},
                   {certfile,"/etc/rabbitmq/ssl/server_cert.pem"},
                   {keyfile,"/etc/rabbitmq/ssl/server_key.pem"},
                   {verify,verify_peer},
                   {fail_if_no_peer_cert,true}]}
  ]}
].

在这里你告诉rabbitmq它将使用哪些证书，确保证书的路径与你复制证书的路径相同。

update-rc.d sensu-server defaults
update-rc.d sensu-api defaults
update-rc.d sensu-client defaults
update-rc.d sensu-dashboard defaults

然后像之前使用的那样复制 SSL client_key 和证书：

cp client_key.pem client_cert.pem  /etc/sensu/ssl/

然后将不同的配置添加到 /etc/sensu/config.json。
