sudo su - solr -c "/usr/share/solr/bin/solr start"
sudo su - solr -c "/usr/share/solr/bin/solr create -c hyrax-core"
sudo su - solr -c "/usr/share/solr/bin/solr stop -all"

Edit the config/database.yml file and update the following parameters:

default: &default
  adapter: postgresql
  encoding: unicode
  pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
  host: localhost
  username: samvera
  password: password  # Replace with the password you set for the PostgreSQL user `samvera`.
  port: 5432
  database: samvera
