＆＃34;服务器没有收听＆＃34;连接到我的远程数据库

Question

我在远程服务器上有一个Postgres数据库。我在pgAdmin中填写此信息。

Name: my-server
Host: SERVER.IP.ADDRESS.HERE
Port: 5432
Maintenance DB: postgres
Username: django
password: mysecretpassword

当我点击＆＃34; OK＆＃34;我收到了这个错误窗口。

Server doesn't listen

The server doesn't accept connections: the connection library reports 
could not connect to server: Connection refused Is the server running on host "SERVER.IP.ADDRESS.HERE" and accepting TCP/IP connections on port 5432? 

如何在运行Ubuntu 14.04的远程服务器上查看Postgres运行的端口？为什么我会收到此错误？

更新

跑SELECT * FROM pg_settings WHERE name = 'port';。港口肯定是5432。

跑nano /etc/postgresql/9.4/main/postgresql.conf。取消注释listen_addresses所以看起来像这样：

listen_addresses = 'localhost','*' 

跑nginx restart，再次尝试连接。同样的错误。

Answer 1

您可以像这样检查端口：SELECT * FROM pg_settings WHERE name = 'port';

Answer 2

正在运行sudo /etc/init.d/postgresql restart摆脱了错误。
