I was following the ruby on rails tutorial to run with postgres but when I try the "rake db:create" I get the following error:
could not connect to server: Permission denied
Is the server running locally and accepting
connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432"?
I have found this question issuing some similar problem but I couldnt make it work anyway.
Repairing Postgresql after upgrading to OSX 10.7 Lion
I have installed homebrew after reading this question and the path is fine, brew doctor shows me no errors on path.
Instead of troubleshooting your socket file permissions, you could try a TCP connection . Add host: localhost
to your config/database.yml
. Of course, this will only work if postgres is listening for TCP traffic. Postgres listens on port 5432 by default, so netstat -an | grep 5432
netstat -an | grep 5432
will tell you if it is listening.

哦,可能是你在另一个应用程序中打开postgre,比如pgadmin http://www.pgadmin.org/尝试关闭任何使用postgre SQL并再次运行命令的应用程序。
I ran into the same problem today and found this blog post below which helped me:
http://nextmarvel.net/blog/2011/09/brew-install-postgresql-on-os-x-lion/
It moves your OS X default postgres binaries into an archive folder and symlinks the homebrew versions in place of them.
TL;DR curl http://nextmarvel.net/blog/downloads/fixBrewLionPostgres.sh | sh
curl http://nextmarvel.net/blog/downloads/fixBrewLionPostgres.sh | sh
I had the same issue. After unsuccessfully trying all the suggestions posted above, I finally quit out of terminal and restarted it.
This worked.
只需检查你的config / database.yml是否有------ host:localhost和port :(由netstat -an | grep 5432或5433自行检查)
I also ran into this problem because I had both the mysql and pg gems active in my Gemfile.
I commented out the mysql gem:
# mysql
Then ran:
bundle install
and then:
rake db:migrate
and it worked like a charm.
