当我安装 Ceilometer 时，在 OpenStack 安装教程的“验证操作”阶段，我运行以下命令，但没有成功。
[root@controller3 gnocchi]# gnocchi resource list --type image
Unable to establish connection to http://localhost:8041/v1/resource/image?: HTTPConnectionPool(host='localhost', port=8041): Max retries exceeded with url: /v1/resource/image (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x2ff4950>: Failed to establish a new connection: [Errno 111] Connection refused',))
当我完成 gnocchi 安装并运行gnocchi-upgrade时，没关系。但接下来，当我运行时gnocchi-api，gnocchi-api.log显示 WSGI Address already in use。你能告诉我如何解决吗？谢谢 ！
