BOSH hadoop-release 错误

Question

我正在尝试在本地 VM 上的 BOSH-lite 中部署 hadoop-release，在部署时我收到了 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。请问ssh vcap@192.168.50.4（密码c1oudc0w）并输入ss -ltn并确认postgres端口（5432）已绑定：

LISTEN      0    128                 127.0.0.1:5432        *:*

postgres 正在运行 ps auxwww | grep postgres:
