Обсуждение: Newbie: problem Connecting to Server
I'm running Redhat Linux 8. I have registration to the Redhat Network so
I'm probably running the latest version of postgre sql available. I also
have Redhat Databse v2.1 installed, but whenever I try to start a session,
I get the following error message:
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"?
Please help me configure my system so that I can connect and begin to use
postgresql.
I sorta had the same problem using pgAccess. The way to correct my problem was to start the postmaster using the TCP/IP options.
I now use the following to start postmaster:
pg_ctl start -D /path to data -o -i
the -i option enables 'listening' on TCP ports.

TIP 5: Have you checked our extensive FAQ?
Looks like no one has corrected you, alex, so, as it pertains to redhat, a user of which I am not, you may have directedFrustrated correctly. I just wanted to add to the comment below about "option -i" that the postgresql.conf file has a setting in it, "tcpip_socket"which can be set to the value true after being uncommented. That way you won't have to specify the option ifyou restart the PostgreSQL manually. > -----Original Message----- > From: alex b.

Somehow I missed this the first time around....
With an RPM install of PostgreSQL (which RedHat Database is), please consult
README.rpm-dist (find it with 'rpm -ql postgresql |grep rpm').
The short of it:
The RPM install scripts handle the user creation. All one must do is (as
root): '/sbin/service postgresql start' to get an initdb done and postmaster
started. Then edit /var/lib/pgsql/data/pg_hba.conf to allow access to the
client IP address, and edit postgresql.conf (in the same directory) for
tcpip_socket to be true (if you are doing TCP/IP connections, that is).
To get postgresql started automatically at boot, do (assuming you want
postgresql to run in runlevels 3, 4, and 5): '/sbin/chkconfig --level 345
postgresql on'
List the currently valid runlevels with '/sbin/chkconfig --list postgresql'
If it complains about postgresql not be a known service, execute
'/sbin/chkconfig --add postgresql' -- if that doesn't work, check to see if
the postgresql-server RPM is installed ('rpm -qa|grep postgresql').
