psql: could not connect to server: Permission denied

Description

Hi, I have followed all the installation steps and all completed successfully. However, the following command fails after I start the server (i.e. sudo port load :

$ psql -d postgres -U postgres
psql: 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"?

The server appears to be started:

postgres         307   0.0  0.0  2445872    544   ??  Ss    1:57PM   0:00.72 postgres: stats collector process

However, the last line of the above doesn't specify a numerical value for the PID. Last but not least, I'm using a pre-release version Mac OS 10.7 (Build 11A511).

Lion is still under NDA, so we'll have to wait for a few days to discuss that here...

I experienced the same problem and worked around it by issuing the following commands:

DIR=/opt/local/var/db/postgresql91/defaultdb
sudo launchctl unload -w /Library/LaunchDaemons/org.macports.postgresql91-server.plist
sudo mkdir -p $DIR
sudo chown postgres:postgres $DIR
sudo su postgres -c "/opt/local/lib/postgresql91/bin/initdb -D $DIR"
sudo launchctl load -w /Library/LaunchDaemons/org.macports.postgresql91-server.plist
psql -h localhost -U postgres

Do the following if you should get the notorious FATAL: could not create shared memory segment: Cannot allocate memory error after the initdb command:

sudo sysctl -w kern.sysv.shmall=65536
sudo sysctl -w kern.sysv.shmmax=16777216

Hope that helps.

comment:3 Changed 3 years ago by jasonw@…

I was able to get it working with the database I had already configured. It seems that Lion ships with PostgreSQL clients (perhaps after installing Xcode):

$ which psql
/usr/bin/psql
$ psql postgres postgres
psql: 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"?

However, if I force psql to use TCPIP by specifying a hostname, all is well:

$ psql -h localhost postgres postgres
psql (9.0.4)
Type "help" for help.

postgres=#

Alternatively, when I put the MacPorts clients first in my path, I had no problem connecting using Unix domain sockets:

$ export PATH=/opt/local/lib/postgresql90/bin:$PATH
$ which psql
/opt/local/lib/postgresql90/bin/psql
$ psql postgres postgres
psql (9.0.4)
Type "help" for help.

postgres=#

Hope this helps!

  • Status changed from new to closed
  • Resolution set to invalid

If I'm reading comment:3 correctly, there's only a problem if you're not running the psql installed by macports. So there's nothing to fix. Reopen if this is incorrect.
