Thread: help with rpm script

Hello,

I am building an rpm for Mitle SME (a scaled down redhat 7.3) and have all functions working except:

I need to have the rpm when installed create a database and a user with privilege to that database.
These are the command functions I need to execute within the rpm...

# service postgresql start 
# su postgres 
# createdb account 
# psql account < my1.sql 
# psql account < my2.sql 
# exit 

But, I need these functions to be executed when someone installs my rpm. For Mysql, I have the following
in the %post of my spec file:

-------------------snippet-from-spec-file------------------------- 
%post 
# This section creates the database, dbuser, dbpasswd and # data after the package has been installed 


pw=`/bin/cat /etc/openldap/ldap.pw` 
/bin/echo exit | /usr/bin/mysql --password=$pw mydb 2>&1 &> /dev/null 
if [ "$?" = "1" ; then
/bin/echo "Creating mydb database..." 
/usr/bin/mysqladmin --password=$pw create mydb 
/bin/echo "grant all on mydb.* to dude@localhost identified by 'dudepass';" | /usr/bin/mysql --password=$pw 
/usr/bin/mysql --password=$pw mydb < /path/to/my.sql 
/usr/bin/mysqladmin --password=$pw reload 
fi 


--------------end-of-snippet-from-spec-------------------------- 
What commands could I use to complete similar needs for
a postgresql database to be created by an rpm?

Thank you for any help.

It is an extremely bad idea to do this.  Scriptlets in RPM run in a weird 
mode.

Rather, in your spec file, do an initdb in the %install phase, and run a 
restore of the precreated database (in %install, again, but this might be a 
little tricky to do, since the postmaster as associated executables are in 
the buildroot, not in a really runnable position).  Then have this packaged 
as, say, postgresql-data or somesuch.  Add the precreated dump (if it's a 
dumpall, it will have the database name and all users as part of the dump).

Or have the initscript in /etc/rc.d/init.d perform the restore immediately 
after the initdb that the first initscript run will do.

But you really don't want to be doing this in %post.  What if it's an upgrade?  
RPM upgrades and installs are identical from the scriptlet's point of view 
(except for the one parameter).  I have a little experience in this regard, 
having maintained the mainline PostgreSQL RPM's for four years.
