Konfiguracja Dyskursu na Ubuntu 12.04 LTS

Question

Mam nową bazę danych do instalacji Dyskursu w PostgreSQL. Gdy uruchomię program rake db: migrate, tworzy większość tabel, ale następnie kończy się niepowodzeniem:

-- execute("INSERT INTO archetypes (name_key, created_at, updated_at) VALUES ('poll', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP)") 
    -> 0.0009s 
-- add_column(:forum_threads, :archetype_id, :integer, {:default=>1, :null=>false}) 
    -> 0.0209s 
== CreateArchetypes: migrated (0.0424s) ====================================== 

== AddMetaDataToForumThreads: migrating ====================================== 
-- execute("CREATE EXTENSION IF NOT EXISTS hstore") 
rake aborted! 
An error has occurred, this and all later migrations canceled: 

PG::Error: ERROR: could not open extension control file "/usr/share/postgresql/9.1/extension/hstore.control": No such file or directory

Dowolna wskazówka?

Answer 1

Wygląda na to, że z powodu błędu bazy danych "nie można otworzyć pliku kontrolnego rozszerzenia", próbując uzyskać CREATE EXTENSION [...] hstore, że rozszerzenie hstore nie jest zainstalowane.

W systemie Ubuntu można zainstalować rozszerzenie, instalując pakiet postgresql-contrib.

sudo apt-get install postgresql-contrib 

Użytkownik terriaray udokumentował enabling hstore w Gist.

Answer 2

Jeśli masz dwa Postgresql instalacji na Ubuntu, takich jak 9.1 i 9.3

Przed uruchomieniem konkretną instalację wersji, może trzeba dodać odpowiednie postgres repo używając ich instructions który mam parafrazowanie poniżej w przypadku ich zniknąć:

deb http://apt.postgresql.org/pub/repos/apt/ UBUNTU_VERSION_NAME-pgdg main 
sudo apt-get install wget ca-certificates 
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add - 
apt-get update 

(powinny być zastąpione przez UBUNTU_VERSION_NAME wierny lub niezależnie od wersji jest nazwa)

wtedy Można użyć polecenia poniżej, aby zainstalować rozszerzenie hstore na każdym serwerze oddzielnie:

PostgreSQL 9.1:

sudo apt-get install postgresql-contrib-9.1 

PostgreSQL 9.3:

sudo apt-get install postgresql-contrib
