Question

我正在尝试使用home brew在我的MAC上安装PostgreSQL，当我尝试运行命令psql时，我收到以下错误

Harshas-MacBook-Pro:~ harshamv$ 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"?

看起来系统无法识别安装。

Harshas-MacBook-Pro:~ harshamv$ locate psql | grep /bin
/usr/local/Cellar/postgresql/9.4.0/bin/psql
/usr/local/bin/psql

该过程似乎正在运行

    Harshas-MacBook-Pro:~ harshamv$ ps -aef|grep postgres  
      501 12075 11832   0 11:54AM ttys001    0:00.00 grep postgres

也是plist文件

Harshas-MacBook-Pro:~ harshamv$ launchctl load -w /usr/local/Cellar/postgresql/9.4.0/homebrew.mxcl.postgresql.plist  
/usr/local/Cellar/postgresql/9.4.0/homebrew.mxcl.postgresql.plist: Operation already in progress


Harshas-MacBook-Pro:~ harshamv$ which psql
/usr/local/bin/psql

Harshas-MacBook-Pro:~ harshamv$ echo $PATH
/Users/harshamv/.rvm/gems/ruby-2.1.2/bin:/Users/harshamv/.rvm/gems/ruby-2.1.2@global/bin:/Users/harshamv/.rvm/rubies/ruby-2.1.2/bin:/Applications/bin/php5/bin/:/Applications/Mamp/htdocs/prayag/lib/Cake/Console:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/harshamv/.rvm/bin:/usr/local/mongodb/bin

您没有运行PostgreSQL服务器。您的ps输出仅显示您自己的ps grep。

您也可能安装了两个版本的PostgreSQL，并且您正在运行与错误的一个相关联的psql客户端。您可以运行which -a psql来查看PATH中的所有psql二进制文件。
