Postgres won't start after setting ssl=on

The private keys needs to be readable by the same user the server runs
under. This is distribution-dependent and may not be 'root'.
In my case I run Red Hat which uses the 'postgres' user, so:

chown postgres.postgres /var/lib/pgsql/data/server.*

Hi, I'm trying to require SSL for Postgres connections from certain
IPs.. This is on Postgres 9.0.

First, I've followed the directions at:

http://www.postgresql.org/docs/9.0/static/ssl-tcp.html

I've created the files server.crt and server.key. I've also removed
the passphrase from the key so Postgres can start automatically.
Finally, I ran:

chmod 0600 server.key

The permissions on server.key are now:

-rw------- 1 root root 887 Oct 10 03:42 server.key

However, when I set ssl = on in postgresql.conf and start the server,
I get the logged error:

2010-10-10 03:47:07 UTC FATAL: could not load private key file
"server.key": Permission denied

I'm logged on as root. Any ideas? Thanks!

Sweet! That fixed it.. Rock on..

Of course now let's see if I can connect from my Mac client :)

The owner of these new files needs to be the same as that of your Pg data dir in
general or postgresql.conf specifically, and that owner be the same as the
process that runs the Pg server. Are you running Pg as root? (In any event,
you should have another user; running programs or servers as root when they
don't need root powers is generally a bad idea.) -- Darren Duncan

Yup, my bad.. I should have noticed all the other files were owned by
postgres (and I assume that's what the process is running under)..
I'm still a Unix newbie, but learning quickly..

Everything's working, and to my surprise pgAdmin connected using SSL
on the first try.. No need to mess with anything on the client side
of things..

So now I have my database, which only accepts TCP/IP "host"
connections from the IP addresses of my web servers, and then requires
"hostssl" from my home cable modem IP. Everything else is blocked.
Should be decently secure :)

Actually, unless you've hacked the pg code, it won't start as root.

While I do appreciate the vote of confidence, rest assured you will
never see a post from me that starts with "So I've been hacking the pg
code and..."

Does postgres run as root or as the postgres user. I suspect you want
postgres to own that file.

To understand recursion, one must first understand recursion.

Actually, we get *plenty* of those.

Cheers,
