Hi,
I have two "identical" servers running CentOS 5.2 with PostgreSQL 8.3.5
installed on both. Prior to a reboot this morning, I was able to
connect, remotely, to both of them and doing telnet <serve-rname> 5432
brought up a prompt for them as well.
However, I am now in the unfortunate situation of not being able to
connect remotely to one particular server and cannot for the life of me
figure out why I am getting a connection refused:
Connection refused. Check that the hostname and port are correct and
that the postmaster is accepting TCP/IP connections.
I can ssh into the server and do a psql <db-name> from the
/var/lib/pgsql command prompt, as user postgres. But, when I try to use
a different user (psql -U user -p <db-name>), from the same prompt, I get:
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.0"?
When I look into the /tmp directory for the domain socket, I see:
srwxrwxrwx 1 postgres postgres 0 Mar 9 17:44 .s.PGSQL.5432
-rw------- 1 postgres postgres 25 Mar 9 17:44 .s.PGSQL.5432.lock
Also, here is the relevant piece of my pg_hba.conf file:
local all all trust
# IPv4 local connections:
host all all 127.0.0.1/32 trust
host all all 192.168.0.0/16 md5
host all all 172.16.0.0/16 password # for a
VMWare instance
# IPv6 local connections:
host all all ::1/128 trust
And, lastly, I use the following script as the postgres user to start
PostgreSQL from the command prompt, manually:
#!/bin/bash
ARGV=$1
PG_HOME=/var/lib/pgsql
PG_WORK_DIR=$PG_HOME/data
if [ "$1" = "start" ]
then
pg_ctl -D $PG_WORK_DIR -l logfile start
elif [ "$1" = "stop" ]
then
pg_ctl -D $PG_WORK_DIR stop
fi
Nothing, that I am aware of, has changed on this server that would
prevent the remote connection. I have both SELinux and iptables
disabled (off by default) since this is inside a firewall on a home
network and is not available to the outside world.
Any idea why I am no longer able to connect?
Thanks for any and all help.
John
