I am trying to create the database and I am a newbie.
When I install PostgreSQL, I gave this command
sudo yum install postgresql postgresql-server
and later I modified the config file
sudo vim /var/lib/pgsql/data/pg_hba.conf
and modified as
local all all trust host all all 127.0.0.1/32 trust host all all ::1/128 trust host all all 0.0.0.0/0 md5
While I am trying to startup the postgresql service
sudo service postgresql initdb > Data directory is not empty! [FAILED] sudo chkconfig postgresql on sudo service postgresql start Starting postgresql service: [ OK ]
i am getting the comment like this.
please help me in this.
Thanks in advance..
On systemd based systems like RHEL/CentOS 7 and Fedora the procedure for running initdb is somewhat different. This is no longer done by the init scripts (which no longer exist), and the new procedure is much closer to the upstream instructions.
You must first
su to the
postgres user, and then run
pg_ctl initdb. It’s not necessary to provide a data directory if you are using a Red Hat build as its default automatically chooses the default data directory
# su - postgres $ pg_ctl initdb $ exit #
Of course, you only do this once, on first installation, to set up the initial data directory. You would not do it again unless you were creating a completely new installation or restoring from a disaster.
