自制postgres坏了

Question

> launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
/usr/local/Cellar/postgresql/9.4.0/homebrew.mxcl.postgresql.plist: Operation already in progress

但是，postgres似乎没有运行。

> ps auxw | grep post
billmcn           670   0.0  0.0  2424272    452 s000  R+   10:12PM   0:00.01 grep post

并且无法与命令行客户端连接。

> psql
psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

据我所知，我已经尝试了在讨论这个问题的其他Stackoverflow线程上建议的所有修复。具体地说：

null

ll /usr/local/var/
drwxr-xr-x  3 billmcn  admin  102 Dec 20 12:44 cache
drwxr--r--  2 root     admin   68 Dec 29 21:37 postgres

ll /usr/local/var/
drwxr-xr-x   3 billmcn  admin  102 Dec 20 12:44 cache
drwx------  23 billmcn  admin  782 Dec 30 10:51 postgres

Answer 1

我在新安装的约塞米蒂上使用自制软件安装postgres也遇到了同样的问题。

首先，我的brew配置如下所示：

HOMEBREW_VERSION: 0.9.5
ORIGIN: https://github.com/Homebrew/homebrew

OS X: 10.10.1-x86_64

System Ruby: 2.0.0-481
Perl: /usr/bin/perl
Python: /usr/bin/python
Ruby: ~/.rvm/rubies/ruby-2.1.1/bin/ruby

我注意到的第一件事是我没有/usr/local/var/postgres的写权限。发布sudo chown-r`whoami`/usr/local/var/postgres很容易改变了这一点，然后我重新安装了postgresql并执行了
