Question

我正在尝试在本地 VM 上的 BOSH-lite 中部署 hadoop-release，同时部署我得到Error while reserving job: PG:: Error: could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on 5432?

PostgreSQL似乎没有在您的 BOSH lite 上运行。我想检查一下。能否请您ssh vcap@192.168.50.4（密码c1oudc0w）键入ss -ltn并确认 postgres 端口（5432）已绑定：

LISTEN      0    128                 127.0.0.1:5432        *:*

并且 postgres 正在运行ps auxwww | grep postgres：
