我已经使用http://sensuapp.org/docs/latest/guide中的说明在 CentOS-6.5 上安装了 sensu， 但我似乎无法启动 sensu-server、sensu-client 甚至 sensu-api。任何建议将不胜感激。

以下是 /var/log/sensu/sensu-server.log 中记录的错误：

通常是消息

unable to resolve server address (EventMachine::ConnectionError)

是由于 sensu 组件（服务器、客户端、api）无法连接到您的 RabbitMQ 服务器。

检查事项：

  1. RabbitMQ 服务器是否启动并运行？

    检查与service rabbitmq-server status

  2. RabbitMQ 服务器是否可解析/可访问？

    如果您遵循 sensu 文档，我假设您的 RabbitMQ 是本地的，所以这应该不是问题。

  3. 升级到最新版本的 sensu（当前为 0.16.0）。

    0.13.0 每个问题#747中都包含了对 RabbitMQ 连接失败崩溃的修复。
