问题描述
在此之前，请注意，我在 Stack Overflow 和网络上的文章中发现了几个类似的问题，但没有一个能帮助我解决问题:
Before anything, please note that I have found several similar questions on Stack Overflow and articles all over the web, but none of those helped me fix my issue:
现在，问题来了:
- 我有一个非常棒的 Rails 应用.
- 与我的合作者一起，我们使用 GitHub 一起工作.
- 我们有一个
master和一个mvp分支. - 我最近使用 Homebrew (Mac) 更新了我的
git版本. - 我们使用 Foreman 在本地启动我们的应用.
- I have a Rails app that works like a charm.
- With my collaborator, we use GitHub to work together.
- We have a
masterand anmvpbranches. - I recently updated my
gitversion with Homebrew (Mac). - We use Foreman to start our app locally.
现在，当我尝试在本地启动应用程序时，出现以下错误:
Now, when I try to launch the app locally, I get the following error:
PG::ConnectionBad at /
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?
我多次尝试重新启动计算机.
I tried to reboot my computers several times.
我还查了/usr/local/var/postgres的内容:
PG_VERSION pg_dynshmem pg_multixact pg_snapshots pg_tblspc postgresql.conf
base pg_hba.conf pg_notify pg_stat pg_twophase postmaster.opts
global pg_ident.conf pg_replslot pg_stat_tmp pg_xlog server.log
pg_clog pg_logical pg_serial pg_subtrans postgresql.auto.conf
如您所见，其中没有 postmaster.pid 文件.
As you can see, there is no postmaster.pid file in there.
知道如何解决这个问题吗?
Any idea how I could fix this?
推荐答案
您很可能没电了，并且您的 postgresql 服务器没有正确关闭.
You most likely ran out of battery and your postgresql server didn't shutdown correctly.
最简单的解决方法是下载官方的 postgresql 应用程序并启动它:它会强制服务器启动 (http://postgresapp.com/)
The easiest workaround is to download the official postgresql app and launch it: it will force the server to start (http://postgresapp.com/)
这篇关于服务器是否在主机“localhost"上运行?(::1) 并接受端口 5432 上的 TCP/IP 连接?的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
