To initialize the database, the database user must
have the proper permissions to create the database
directories you've mentioned (pgsql, pgsql/data).
Assuming the following:
Database User: postgres
Databsase User's group: database
Database directory: /var/lib/pgsql/data
1. Read the online documentation for your version at
http://www.us.postgresql.org/users-lounge/docs/
2. As root:
create the group database in /etc/group
create the user postgres
mkdir -p /var/lib/pgsql/data
chown -R postgres.database /var/lib/pgsql/
3. Login as postgres and:
add the next 2 lines to postgres' .profile
PGDATA=/var/lib/pgsql/data
export $PGDATA
execute the following from the command line:
initdb -D /var/lib/pgsql/data
postmaster -D /var/lib/pgsql/data &
I think this should do it. If I forgot anything, I'm
sure someone will correct me! ;-)
Best of luck,
