install
$ su root $ yum install postgresql postgresql-server
install pgadmin somewhere, probably on your desktop
this command downloads and installs some components that make pgadmin more useful
$ yum install postgresql-contrib.i386
after that install you still need to run some SQL against your particluar DB:
psql -U postgres -d sfmaps -h localhost < /usr/share/pgsql/contrib/adminpack.sql
Set up the data directory
$ su root $ mkdir /usr/local/pgsql/data $ chown postgres /usr/local/pgsql/data
Initialize the database
$ su postgres $ initdb -D /usr/local/pgsql/data
important file system locations include
/usr/share/pgsql /usr/share/pgadmin (home of pgadmin?) /var/lib/pgsql/data/ /usr/local/pgsql/data/pg_hba.conf (configuration) /usr/local/pgsql/data (data) /usr/local/pgsql/data/pg_log (logs) /usr/local/pgsql/data/postmaster.pid (process id)
restart database server
$ /usr/bin/pg_ctl restart -l /var/lib/pgsql/logfile -D /usr/local/pgsql/data $ /usr/bin/pg_ctl --help
start database server
$ su postgres $ /usr/bin/pg_ctl start -l /var/lib/pgsql/logfile -D /usr/local/pgsql/data
stop database server
$ /usr/bin/pg_ctl stop -D /usr/local/pgsql/data
This will not stop the DB server processes if there are connections. To force the issue use something like this:
$ pg_ctl stop -m f
To reload changes made to config files:
/usr/bin/pg_ctl reload -D /usr/local/pgsql/data
running database server as a daemon process (not tested) This line
su -c '/usr/bin/pg_ctl start -l /var/lib/pgsql/serverlog -D /u01/pgsql/data' postgres
should be in this file
/etc/rc.d/rc.local
security
Once you start making non-local request to the database,
you need to tell Postgres that its OK to talk talk to stranger.
You do this by making changes to
\WindowsPath\pg_hba.conf file
\LinuxPath\pg_hba.conf file
Additionally, you may need to make changes to the firewall of the OS that is hosting PostgresQL.
And in postgresql.conf, you may need to edit these lines:
listen_addresses = '*' port = 5432
