Re: install Postgres on RHED 7

sorry, my fingers split before I can finish all typing:

After the server successful install, I initialize the database an

but when I tried to correct the postgres.conf with the listen_addresses = '*' and port=5432.  Restart the postgresql server I get an error.
redirecting to /bin/systemctl start postgresql.service
job for postgresql.service failed because the control proces exited with error code.  See "systemctl status postgresql.service" and "jouralctl -xe" for details.

what I did wrong here?  Do I need to add listen_addresses = '*' and port = 5432 on both /var/lib/pgsql/data/postgres.conf and /var/lib/pgsql/11/data/postgres.conf ?
thank you for all your help.

Some of them will be from the stock Red Hat repositories, and some will
be from the PGDG repository.  I haven't used that repository, and I
haven't done much on an RPM-based system for a while so I can't give you
any more specific information.

It's possible - but very tedious and difficult - to install a package
with a large dependency tree entirely by hand.  I *have* done this
myself in the past, and I recall a few cases where it literally took two
or three hours to get everything installed to support the specific
package I started out trying to install.  This is why tools like yum
were developed;  they do the work of checking through the list to see
what's required, and where it can be installed from.

This isn't specific to Postgres;  it's how the underlying OS package
system works.  You may want to see if someone in your office has more
experience installing packages on RHEL with yum and ask them to give you
a hand.  You've got several issues around yum's basic operation that you
need to fix, and local network/systems admins should know enough about
your setup to help a lot faster.
