Re: postgres installed via rpms -can't run postmaster or - Mailing list pgsql-admin

Hai Eric

Try the following, let me know if you have any doubts

1. To start postmaster you must be logged in to your PostgreSQL server
   account( postgres). It will not work as root.
create the data dir (eg: /var/postgresql/data)

 # mkdir /var/postgresql/data
 # chown postgres /var/postgresql/data

 create the user "postgres"

        # su - postgres

        $ initdb -D /var/postgresql/data

        $ postmaster -i -D /var/postgresql/data

      This will start the server in the background.

      To stop a server running in the background you can type

        $ kill `cat /var/postgresql/data/postmaster.pid`

 In order to allow TCP/IP connections (rather than only Unix domain socket
ones) you need to pass the "-i" option to "postmaster".

3.   Create a database:

 create a database named 'db'

        $ createdb db

4.   To view the database created, use the following command:

 $ psql -l

 Now postgresql is running, we can view the PID by using the
 following command

 $ ps -ef | grep postmaster

 Then enter

        $ psql db

       Above rule should prompt to database db as
       Welcome to psql 7.3.1, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help on internal slash commands
       \g or terminate with semicolon to execute query
       \q to quit

 db=#

thanks
