Title: [SOLVED] POSTGRESQL as a service
Post by: jessethepro on February 18, 2013, 09:36:03 PM

Hi,

I am trying to run postgresql as a service. When run as user tc through ssh script:

PGDATA=/tmp/maxdb
pg_ctl init
/tmp/tcloop/postgresql/usr/local/bin/postgres -D /tmp/maxdb

Runs without issue.

When put into bootlocal.sh service doesn't start. Anyone have success starting postgres on boot as a service?

Respectfully,
Jesse

bootlocal.sh runs as root.
When you say ssh script did you perhaps mean sh script?

You also should not be referencing /tmp/tcloop/postgresql/

Hi jessethepro
I would also question your use of  /tmp/tcloop.   /tmp/tcloop/postgresql/usr/local/bin/postgres is linked to
/usr/local/bin/postgres  and  /usr/local/bin  is in the path.
postgres -D /tmp/maxdb  is all you need.

Thank you for the great info,

I log in through ssh and run the script with the default shell

I didn't know the path linked to /usr/local/bin. That is great to know.

Changing the start command to postgres -D /tmp/maxdb works perfect when run through the shell,  but won't start when run through bootlocal.sh. If postgres is like mysql, it probably doesn't like being started by root. Is there a way to start a service by user tc through bootlocal.sh?

I tried putting:
echo -e "password for tc" | su tc
Before the postgres commands to switch users and run the last of bootlocal.sh.as user tc, but didn't have much luck with that.

Respectfully,
Jesse

Hi jessethepro
This same type of situation came up recently here:
http://forum.tinycorelinux.net/index.php/topic,14573.msg82686.html#msg82686
So maybe something like:

Code: [Select]

su tc -c 'postgres -D /tmp/maxdb'will do what you need.

Rich,

The command you gave me worked perfectly. I do appreciate the assistance. For future reference, the complete script in bootlocal.sh to start the postgresql server with default unix sockets is:

Code: (bash) [Select]

export PGDATA=/tmp/maxdb #or any other file path for the database
su tc -c 'pg_ctl init'
su tc -c 'postgres -D /tmp/maxdb'

Thank you again for everyones assistance,
Jesse
