我正在使用
postgresql 9.3开发一个rails应用程序.当我今天尝试启动乘客服务器时,我得到了:
PG::ConnectionBad - could not connect to server: Connection refused Is the server running on host "localhost" (217.74.65.145) and accepting TCP/IP connections on port 5432?
没想到,这发生在以前.重启postgres总能解决问题.所以我运行sudo服务postgresql重启并得到:
* Restarting Postgresql 9.3 database server * The Postgresql server Failed to start. Please check the log output: 2014-06-11 10:32:41 CEST LOG: could not bind IPv4 socket: Cannot assign requested address 2014-06-11 10:32:41 CEST HINT: Is another postmaster already running on port 5432? If not,wait a few seconds and retry. 2014-06-11 10:32:41 CEST WARNING: could not create listen socket for "localhost" 2014-06-11 10:32:41 CEST FATAL: could not create any TCP/IP sockets ...fail!
我的postgresql.conf指向默认值:localhost和端口5432.我尝试更改端口,但错误消息是相同的(端口更改除外).
两个ps aux | grep postgresql和ps aux | grep postmaster什么都不返回.
编辑:
在postgresql.conf中,我将listen_addresses更改为127.0.0.1而不是localhost,它完成了技巧,服务器重新启动.我还必须编辑我的应用程序的db config并指向127.0.0.1而不是localhost.但问题是,为什么localhost被认为是217.74.65.145而不是127.0.0.1?
那是我的/ etc / hosts:
127.0.0.1 local 127.0.1.1 jacek-X501A1 127.0.0.1 something.name.non.example.com 127.0.0.1 company.something.name.non.example.com
你的/ etc / hosts坏了.第一行应该是读
