Обсуждение: autostart postgresql

Partial success!
  I have postgresql started and have "createdb testdb"
successfully.  I am having trouble with autostarting
postmaster in RH6.2 however.

  I have copied the file
"/usr/local/postgresql-7.0.2.......postgres-init"  to
/etc/rc.d/init.d and made a softe link to it from .../rc5.d
as follows       ln /etc/rc.d/init.d/postgres.init
/etc/rc.d/rc5.d/S98postgres.init

  postmaster does not autostart upon a reboot.  Do I have to
use a start command or other paramater to tell postgres.init
to start the postmaster up?  I am not good at reading and
deciphering these scripts but would like postgres to
autostart everytime the PC boots to runlevel 5.

  Thanks for all the help from various members so far!

    You should either copy the init script to /etc/rc.d/init.d/
and run
/sbin/chkconfig --add postgres
or run the script with 'install' option (which basically does the
same thing). Messing directly with /etc/rc.d/rc*.d/ is not a very good
idea.

You can't run postmaster as root, so to do this I believe you
have to write a wrapper script and give it a postgres (or whatever
your admin account is named) sticky bit.

Is this the 'one true way' for doing this?

Be happy. It is a way of being wise.

I usually make the script 'su' into postgres and then startup
postmaster. I don't know if this is any better.

See following (and attached) dump of my init script,
/etc/rc.d/init.d/postgresql which should be linked to the runlevel
directories as suitable for your system.

This works automatically on my hosts
