Обсуждение: Remove Postgres from Solaris 10
Hello all,
I have a software solution with a postgres database. The user postgres is abolutly needed for my software.
With Solaris 10, Postgres is automatically installed and uses the user postgres. How can I easily remove the current postgres install from this Solaris 10? Is there a process which is provided from Solaris to remove it? Whats the best way to do it?
Thank you for your help.
Cheers Thomas
I guess what you mean is to remove the "role" postgres so that you can redefine it as a normal user and not remove the binaries that are installed with Postgres as they can be overridden by having right PATH variables Its easy... Modify /etc/user_attr and remove type=role from the postgres line and modify /etc/passwd to set a home path and change default shell to /bin/sh or /bin/bash and set password for it.. and now you have a normal user.. Is this what you are trying to do? -Jignesh Thomas Bräutigam wrote: > Hello all, > > I have a software solution with a postgres database.

There are a couple of options you can take to accomplish this. 1) Remove the role by running ¨roledel postgres¨ . This will remove postgres from /etc/passwd and /etc/user_attr, and you can use useradd to add postgres as a user. 2) Modify ¨postgres¨ from being a role to user. Below are the steps I use: a) run ¨passwd -d postgres¨ b) edit /etc/user_attr and change type for ¨postgres¨ from ¨role¨ to ¨user¨ c) create a home dir for postgres if needed d) use the usermod command to change the home dir and shell -Robert Jignesh K.

Hi Jignesh, But than I have the problem that I have 2 installations of postgres with default settings on one machine. Is it possibleto have two installations with default settings on one machine? Do they not interrupt each other with ports or something else....? Cheers Thomas -----Original Message----- From: J.K.Shah@Sun.COM [mailto:J.K.Shah@Sun.COM] Sent: Dienstag, 29.

It may also affect your kernel settings such as shmmax. Joshua D.

Hi Joshua The problem is this that I need this ports for my default postgres database. Is it than possible to have 2 default postgres databases in parallel? Same ports etc.....? Right now I just used the hammer method and removed the packages from the Solaris 10 version, but this seem to be not theelegant version of doin it.

In our organization, we are running multiple databases on the same box on the default port. However, they all have their own data directories and they listen on different VIP's. Here are the parameters in postrgresql.conf to make it work: unix_socket_directory = 'data directory for a particular DB here' listen_addresses = 'VIP here' port = 5432 On 4/29/08 5:33 PM, "Joshua D.

Hi Joshua, I think I have to explain it a little more detailed - my product uses a postgres database with the standart config (ports etc.) - with Solaris 10 postgres is already installed as standart - I need to replace this Solaris 10 postgres installation with my standart postgres database of my product That is the reason I need to remove the standart postgres installation from Solaris 10 that I can use my own postgres database. My concern is how I can remove this standart Solaris 10 postgres database as quick and efficient as possible that I can putin my postgres database?

Here are my two cents: You dont want to remove packages installed with Solaris by default.. However you may use your own Postgres packages or binaries in different location and not enable Postgres by default. (PostgreSQL is an integral part of Solaris 10 ) Don't forget some of Solaris's own tools like SunMC now uses the bundled postgres in the operating system and hence depends on its existence and tested against it. http://www.sun.com/bigadmin/sundocs/articles/sunmcnew.jsp Removing PostgreSQL packages installed by default is not supported since upgrades to the Operating system will depend on those file installations to exist out in the preset locations. However that does not mean you cannot have your own binaries and use them at the default port. The default database is not enabled by default which means there is no collision of port numbers unless you want both database clusters to be enabled. If thats the case than changing Port numbers in either your database cluster or the default db instance (if init'ed by using svcadm start postgres_82:default for the first time) in /var/postgres/8.2/data/postgresql.conf should be fairly easy. Other option is to use "OpenSolaris" CD images which does not have PostgreSQL installed by default as part of the "CD image" install as of now. http://opensolaris.org/os/project/indiana/resources/getit/ -Jignesh Thomas Bräutigam wrote: > Hi Joshua, > > I think I have to explain it a little more detailed > > - my product uses a postgres database with the standart config (ports etc.) > - with Solaris 10 postgres is already installed as standart > - I need to replace this Solaris 10 postgres installation with my standart postgres database of my product > > That is the reason I need to remove the standart postgres installation from Solaris 10 that I can use my own postgres database. > > My concern is how I can remove this standart Solaris 10 postgres database as quick and efficient as possible that I canput in my postgres database? > > Cheers Thomas > > > > -----Original Message----- > From: Joshua D.

Hi Jignesh What things do I all need to take care when I want to run both postgres databases on the same box. Like the Solaris 10 postgresdb and my postgres db. What parameters to I need to change in the postgresql.conf file? Is there something else I need to take care?

So if you just want to use your own Postgres binary, you don't have to worry about changing the port as long as you don't enable the versions that come with Solaris.

Hi Robert, That's the issue, the database is not running which gets delivered with Solaris 10 but I am not sure if the my customer accidentlyactivates it or not, so I want to be on the safe side of live, that I minimize this risk.
