You will have to adjust the postgres database and the rudder-web.properties file.
Here is a semi-automated procedure:
- Generate a decently fair password. You can use an arbitrary one too.
PASS=`dd if=/dev/urandom count=128 bs=1 2>&1 | md5sum | cut -b-12`
- Update the Postgres database user
su - postgres -c "psql -q -c \"ALTER USER blah WITH PASSWORD '$PASS'\""
- Insert the password in the rudder-web.properties file
sed -i "s%^rudder.jdbc.password.*$%rudder.jdbc.password=$PASS%" /opt/rudder/etc/rudder-web.properties
