Error - R

Answer 1

The essence is to reset every sunspot solr part, that may occur problems.

Delete the complete solr directory. This deletes the complete solr directory for sure - double check!

rm -rf solr

Delete the sunspot solr configuration file config/sunspot.yml.

rm config/sunspot.yml

Stop sunspot solr.

bundle exec rake sunspot:solr:stop

Check if sunspot solr is no longer running. If there are solr processes running note there PID

ps aux | grep solr

Manually kill the solr processes by PID. This command is only needed if bundle exec rake sunspot:solr:stop wasn't successful.

kill -9 PID # (fully turns off solr - double check `ps aux|grep solr`)

Delete your database, double check if you really sure! Then recreate the database and restore the schema from the migration files.

bundle exec rake db:drop
bundle exec rake db:create
bundle exec rake db:migrate

creates a new sunspot configuration config/sunspot.yml.

rails generate sunspot_rails:install

recreates the solr directory

bundle exec rake sunspot:solr:start

create a new solr index

bundle exec rake sunspot:reindex

Finally refill the empty database with your seed data.

bundle exec rake db:seed
