问题描述
免责声明:我经历了相同的标题,但没有一个能帮助我解决我的问题。
我安装并启动了一个 postgresql 服务器:
我首先删除 pgdata/postmaster.pid
以确保与其他帖子不同。
然后pg_ctl start
lsof | grep 5432
-> 什么都没有
pg_ctl start
-> ...侦听 Unix 套接字“sockets/.s.PGsql.5432”...数据库系统已准备好接受连接...
lsof | grep 5432
-> postgres 1495 用户名 4u unix 0x0000000000000000 0t0 16163716 sockets/.s.PGsql.5432 type=STREAM
然后我去:rake db:setup
,我得到:
Could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
Could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
Couldn't create 'seqresults-test' database. Please check your configuration.
rake aborted!
PG::ConnectionBad: Could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
Could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
然后我就可以用客户端访问数据库了。
$ psql
然后
postgres=#
请帮忙!所有这些对我来说都像是黑魔法,但它不起作用。
如果有人能简要解释这是如何工作的,我也将不胜感激。
