Tom,
I didn't write the script; whoever maintains the Slackware package for
PostgreSQL did. Regardless, I'll make the changes you suggest.
In particular, I wonder whether the script's refusal to start if the
pidfile already exists accounts for your report that it fails to
auto-restart after a reboot.
This clears up my uncertainty. The pidfile should not exist after a clean
shutdown, so it should be removed after a crash, too.
could be reduced to just:
else
su postgres -c 'postgres -D /var/lib/pgsql/data &'
exit 0
fi
I'd also strongly recommend making that be "su - postgres -c ..."
rather than the way it is now; it's failing to ensure that the
postmaster is started with the postgres account's login settings.
Done. I wondered about the 'su postgres' because when I run that on the
command line I'm asked for the postgres password. I suppose that since
root's running the init file it's not asked.
I'm not sure about your comment that manual start attempts fail with
LOG: could not bind IPv4 socket: Address already in use
It's pretty hard to believe that that could occur on a freshly
booted system unless the TCP port was in fact already in use ---
ie, either there *is* a running postmaster, or something else is
using port 5432.
I'm not seeing this now, but running the revised script (as root) still
produces this:
Starting PostgreSQL
3753
3755
3756
3757
3758
16481
PostgreSQL daemon already running
Warning: Missing pid file /var/lib/pgsql/data/postmaster.pid
Yet, when I try to access one of my databases I cannot:
[rshepard@salmo ~]$ psql aesi
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
There was no postgres running before I ran /etc/rc.d/rc.postgresql start.
There is also no socket on /tmp.
I'd greatly appreciate learning why the startup script is not working so I
can be confident that either the rc.postgresql file or my command line
invocation will consistenly work properly to start the server. I will
provide whatever system information is needed to help diagnose and fix this
problem.
Many thanks,
Rich
