Обсуждение: Server starts, but I can't connect
Hello All, I am running PostgreSQL 8.4 on Kubuntu 11.04. The server starts without any issues, but I can not connect. I keep getting an invalid user/password error. I am connecting to the localhost, default port, user = postgres, database = postgres I have tried setting the authentication methods to trust in the pg_hba.conf file, but it does not make any difference. What am I doing wrong? Thanks, Craigbert

You could not get that type of error when running "trust"
authentication. So, you aren't. Likely theories are that you forgot to
reload or restart the server after changing pg_hba.conf, or that you did
reload but it didn't "take" because of some error in the modified hba
file (if so, there'll be some complaint about it in the server log
file), or that the file you're changing isn't the one being used by the
server you're actually connecting to.

Tom, Thanks for replying.

Unless you can't (e.g. you're using JDBC or something), try connecting to the UNIX domain socket instead of over TCP/IP. If this is not an option, try changing "md5" to "trust" for the "host ... 127.0.0.1/32" line. But I don't recommend this. It would be better to set up a username and password and use that. If you're just trying to connect using psql as user postgres, try this: craigbert@kubuntu$ sudo su - postgres postgres@kubuntu$ psql If you don't specify a host it should use the UNIX domain socket instead of TCP/IP. > On 07/05/2011 10:11 PM, Tom Lane wrote: >> >> Craigbert<postgresql@mysoftforge.com> writes: >>> >>> Hello All, >>> I am running PostgreSQL 8.4 on Kubuntu 11.04. >>> The server starts without any issues, but I can not connect.

Thanks Michael and everyone else. You guys nailed it. I was setting the UNIX sockets to trust instead of IP.
