two versions on same linux

[Paul Gimpelj]

Hi,

I have redhat 7.3 and postgres 7.2

Is there a way to have 7.4 installed together with postgres 7.2 ? and both running at the same time,
with of course different data directories.

should i use the generic postgres or the rpm'd.

The existing redhat has no passwords for postgres, and even if if assign one to user postgres,
postgres ignores it.

thanks
paul

I would recommend one on the default port (5432). I have also used,
without problems (on RedHat 7.3) ports 5434, 5435, 5436, 5437, 15437.

What I would do (more experienced people, pls. correct me) is to check
your /etc/services file to see what ports are used for what (e.g.:
...
cfengine 5308/tcp # CFengine
cfengine 5308/udp # CFengine
...
Means: if you use Cold Fusion (cf) don't use port 5308.

If you use outside packages that use a port but are not standard (sorry,
no good examples), avoid their port(s).

It used to be that any port over 10,000 was "open". I suspect it's not
really true anymore, but usually safe.

You can also change your port at any time by changing (or adding) the
value in postgresql.conf:
port = 5432
can become:
port = 15432
or
port = 5434
etc.

Presumably the respective RPMs will conflict between the different
versions, which is a bit of a problem.

You could of course install one or the other or even both from source,
as long as you choose a specific place to stick them.

Under the circumstances, I'd be inclined to do this:

- Install the PG 7.4 RPMs, in order to have things like Perl support
managed by the package management system.

Personally, I'd rather stick hot needles in my eyes (add further
gruesome details as needed ;-)) than manage Perl stuff by hand.

- Install PG 7.2 AND 7.4 in source code form in some place that YOU
manage, and run the database clusters out of that.

A naming convention could be to stick them in /opt; you'd configure
the source builds something like:

%postgresql-7.2.5> ./configure --prefix=/opt/postgres/7.2.5
[then build and install 7.2.5]

%postgresql-7.4.2> ./configure --prefix=/opt/postgres/7.4.2
[then build and install 7.4.2]

You'd need to customize both "init" scripts in /etc/rc.d, perhaps
basing them on the ones provided by the RPM file.

That's probably based on the ACLs configured in the pg_hba.conf file;
if there are "trust" entries there, passwords can get ignored...

thanks,
I used tar.gz version,
now trying to get regression working.

I want two simo servers.
Any suggestions on port numbers?
