Обсуждение: 9.5 CentOS 7 setting PGDATA for systemctl
Evening, morning, or afternoon,
So I'm trying to go back to a stock rpm package (vs my full custom,
builds). This is a learning curve, not only because it's all "whacked
pathing (in my eyes:)) but rhel7 is a #$%$# with all the things they
changed.
Sooo
I've got servers built and I've got the correct data path initialized
and postgres can start the db " /usr/pgsql-9.5/bin/pg_ctl -D
/pgsql/9.5/data -l logfile start"
But obviously systemctl start postgresql-9.5.server loses it's head
because it has no idea where my Data directory is and setting , PGDATA
as a variable, doesn't seem to work.
So how do I kick CentOS 7 in the teeth and make it change it's
attitude regarding where I have put things? /var/lib/pgsql (really?)
I don't want to do symlinks.
I've got it installed and running, but postgres can't be the only
place to start/stop the server. I need systemctl to handle these tasks
as well.
The init program is all kinds of weirdness.
Any pointers, as I'm starting to lose sleep over this! :)
Thanks
Tory
PGDATA=`sed -n 's/Environment=PGDATA=//p' "${SERVICE_FILE}"`
and
# this parsing technique fails for PGDATA pathnames containing spaces,
# but there's not much I can do about it given systemctl's output format...
PGDATA=`systemctl show -p Environment "${SERVICE_NAME}.service" |
sed 's/^Environment=//' | tr ' ' '\n' |
sed -n 's/^PGDATA=//p' | tail -n 1`
if [ x"$PGDATA" = x ]; then
echo "failed to find PGDATA setting in ${SERVICE_NAME}.service"
exit 1

So where did you get the 'stock' RPM's from, CentOS or the Postgres repos?

This would be the init program included with the RPM?
Is it written for traditional init or systemd?
