How to install Postgres 8

Important.png Note:
This howto is created with information extracted from forums. Proceed at your own risk.

Warning.png Warning:
The command below will install postgres and update postgres-libs. For dependency resolution it will also install tcl and mx from the base repository.

If you see other packages, such as perl or php, abort the installation. This might occur because you have installed perl-CGI-Session or perl-DBD-Pg. These two packages might be on your system because you have installed otrs or another aplication. You can check if they are still needed:

rpm -q --whatrequires perl-CGI-Session perl-DBD-Pg

If that answers no packages need ... you can safely remove these packages

yum remove perl-CGI-Session perl-DBD-Pg

Enable centosplus repository and install postgres (at the time of writing this is version 8.1.9)

yum --enablerepo=centosplus install postgresql postgresql-contrib postgresql-devel postgresql-docs postgresql-pl postgresql-python postgresql-test

After install, ignore the post-upgrade and restart message

Start postgres

/etc/init.d/postgresql start

Then make the necessary custom templates:

mkdir -p /etc/e-smith/templates/var/lib/pgsql/data
mkdir -p /etc/e-smith/templates-custom/var/lib/pgsql/data
cp /var/lib/pgsql/data/postgresql.conf /etc/e-smith/templates/var/lib/pgsql/data
cp /var/lib/pgsql/data/pg_hba.conf /etc/e-smith/templates/var/lib/pgsql/data
cp /var/lib/pgsql/data/postgresql.conf /etc/e-smith/templates-custom/var/lib/pgsql/data
cp /var/lib/pgsql/data/pg_hba.conf /etc/e-smith/templates-custom/var/lib/pgsql/data

Now login as postgres user:

su postgres

Then access to superuser database, set a password and exit.

psql -U postgres -d template1
alter user postgres with encrypted password 'add_your_pass_here';

Edit the file /etc/e-smith/templates-custom/var/lib/pgsql/data/postgresql.conf remove # and change the following settings:

ssl = on
password_encryption = on
listen_addresses = 'localhost'

Then copy your server SSL keys:

cd /var/lib/pgsql/data
cp /etc/httpd/conf/ssl.crt/server.crt .
cp /etc/httpd/conf/ssl.key/server.key .
chown postgres:postgres server.*

Edit the file /etc/e-smith/templates-custom/var/lib/pgsql/data/pg_hba.conf and change the following settings:

local    all   all                    md5
host     all   all    md5
host     all   all    ::1/128         md5

and add at the end:

host    all    all  reject

Be sure to add an extra white line at the end.That why you got an extra line on above box!

Expand template:

expand-template /var/lib/pgsql/data/pg_hba.conf
expand-template /var/lib/pgsql/data/postgresql.conf

Restart with new settings:

/etc/init.d/postgresql stop
/etc/init.d/postgresql start

and add the symlinks to start automatically:

ln -s /etc/init.d/postgresql /etc/rc.d/rc7.d/S56postgresql
ln -s /etc/init.d/postgresql /etc/rc.d/rc6.d/K03postgresql

To ensure everything is all right:

signal-event post-upgrade
signal-event reboot

Testing your environment

To test if you have set postgres password correctly:

su postgres
psql -U postgres -d template1

and enter the password you have set above. If all is correct, you should enter the postgres console. Then exit:


and exit from postgres user:
