Thread: How to check whether PostgreSQL server is up and running?
| Hi, After having various error message in starting PostgreSQL version 8.2.11; finally uninstalled/deleted it. Now trying my luck on 8.3.7, but things haven't changed for me. When I try to check that postmaster server is running or not? I get the following error: $ postmaster -D /usr/local/pgsql/data LOG: could not translate host name "localhost", service "5432" to address: Name or service not known WARNING: could not create listen socket for "localhost" FATAL: could not create any TCP/IP sockets ....................................................................... Similarly when I try to start postgres server with [postgres@callisto postgresql-8.3.7]$ pg_ctl -D pg8 start postgres cannot access the server configuration file "/usr/local/pgsql/postgresql-8.3.7/pg8/postgresql.conf": No such file or directory server starting Have no idea what's wrong and where the problem is? Do I need to change/edit some of Environment variable settings or what? Or should I reinstall PostgreSQL with Yum?? Or should give up using PostgreSQL and switch to some other DB like MySQL etc... No idea what to do.....? Thanks in advance for help. -Jan Muhammad |

Do you use SElinux?

No, it looks like his DNS setup is broken. Not being able to translate
"localhost" to "127.0.0.1" will break most networking services, not
only Postgres ...

Ok let's to create a cluster for you, be sure the pg8 directory owned by postgres user and the directory is empty.
[postgres@callisto]$ initdb -D /usr/local/pgsql/postgresql-8.3.7/pg8 -U postgres -W
Type your password if they ask, wait initdb process until finish.
And try the server:
[postgres@callisto]$ pg_ctl -D /usr/local/pgsql/postgresql-8.3.7/pg8 start
enter to database postgres with user postgres and type your password
[postgres@callisto]$ psql postgres postgres -W
Tell me if this not work.

| Hi, Got it working now, though after several searches and hit-n-trials.... The problem was in my "/pgsql/data/pg_hba.conf"; where it needed my machine's IP. Now got it working. But the real issue of service is not yet being recognized with in the command: # service postgresql status postgresql: unrecognized service Or even: #service pg_ctl status pg_ctl: unrecognized service And strange is when I do: # /sbin/service --status-all I can see among other service (pg_ctl) running: pg_ctl: server is running (PID: 29330) /usr/local/pgsql/bin/postgres "-i" "-D" "/usr/local/pgsql/data" Don't know what is/was issue; but anyways Thanks for helping.

The service command in redhat is designed to work with /etc/init.d/ scripts that are installed by proper rpm packages. The service script that comes with a source install is NOT designed to work properly with that specific package. If you want service to work properly, I'd recommend sticking to the PGDG redhat packages, it makes life much easier, especially for beginners.
