我真的有这个问题了一段时间,但我终于决定采取.最初使用Brew安装Postgres.
升级到OSX 10.8.2后才能收到
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"?
当我打字时出错
$psql
命令.
我看到以下过程：
$ps auxw | grep post Tulsa 59222 0.0 0.2 2483256 14808 ??

您尚未启动Postgres服务器. Postgres的一些dmg软件包将其设置为在启动时作为服务运行.但是没有安装.
你需要初始化一个数据目录,开始postgres,然后从那里去.
initdb /some/directory # just do this ONCE pg_ctl -D /some/directory start # many other options,e.g. logging,available here psql postgres
您可以为数据目录设置一个环境变量,稍后将不再需要-D标志.你可以稍后再看.
