Wygląda na to, że użytkownik nie może połączyć się z bazą danych MySQL DB. Wypróbuj te polecenia w konsoli:

mysql -u root -p

A kiedy poproszony, podaj hasło jako „admin”

Jeśli jest to możliwe, to powinno być dobrze iść.

Hasło jest nieprawidłowe dla użytkownika root w pliku config/database.yml. Zawsze możesz użyć polecenia mysqladmin, aby zmienić hasło użytkownika root, jeśli go nie pamiętasz.

masz na myśli run „mysqladmin - u administratora hasła root "? Ponieważ jeśli próbuję uruchomić, otrzymuję polecenie '-bash: mysqladmin: command not found' – user852974

Gdzie znajduje się twój mysql? Jak to zainstalowałeś? –

@ChrisLedet Mam również ten problem (OSX) i zainstalowałem mysql z homebrew. Co mogę zrobić?? Nigdy nie utworzyłem hasła po zainstalowaniu mysql. – sixty4bit

Odpowiedź jest w pytaniu> MySQL błąd Access denied for user 'root @ localhost'

Zastosuj użytkownika root z hasłem administratora do group_chat_development bazy MySQL

aktualizacja Wydaje mi się, że możesz nie chcieć używać msQL w ogóle dla twojego dev i przetestować bazy danych, w takim przypadku zmień ustawienia testowania i programowania bazy danych.yml na

# SQLite version 3.x 
# gem install sqlite3-ruby (not necessary on OS X Leopard) 
development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    pool: 5 
    timeout: 5000 

# Warning: The database defined as "test" will be erased and 
# re-generated from your development database when you run "rake". 
# Do not set this db to the same as development or production. 
test: 
    adapter: sqlite3 
    database: db/test.sqlite3 
    pool: 5 
    timeout: 5000

Jeśli nie wiesz, jak używać narzędzi MySQL, powinieneś przyzwyczaić się do ich używania już wkrótce, ponieważ najprawdopodobniej będziesz ich potrzebował w środowisku twojego serwera produkcyjnego. Znajdziesz tam odnośniki do odpowiedniej wersji MySQL, której używasz tutaj http://dev.mysql.com/doc/ Użyj administratora MySQL, aby ustawić uprawnienia użytkownika.

powinieneś podać pole "host:" w devlepment w pliku database.yml. nazwa hosta musi być adresem "IP", np. "127.0.0.1" lub czymś .. tj. "Host: 127.0.0.1" i ponownie uruchomić serwer i wpisać na adres taki jak "127.0.0.1:3000" tutaj 3000 to port nomber ...

Po co to wszystko majstrować przy pomocy ip/port? Przyjęta odpowiedź wskazuje już na nieważne dane uwierzytelniające – RichardTheKiwi

Poręczna podpowiedź domowa - utknąłem na tym też, ale znalazłem tamtą pętlę (127.0.0.1)! = 'Localhost' ... Miałem hosta: 127.0.0.1 i byłem widząc ten dokładny problem. Szybka zmiana na "localhost" naprawiła to dla mnie ... mam nadzieję, że pomoże komuś.

development: 
adapter: mysql2 
database: mydb 
host: localhost 
username: root 
password: mypass

Jeśli ustawienie mysql hasło roota po raz pierwszy, a następnie wpisz następujące polecenia następujące:

hasło mysqladmin

Zostaniesz poproszony o nowe hasło i potwierdź hasło.

Po potwierdzeniu spróbuj zalogować się przy użyciu rootu użytkownika i hasła, które właśnie ustawiłeś.

mysql 'root @ your-new-password'

Uwaga: Musisz się zalogować jako root tylko wtedy będzie można ustawić mysql hasło.

Dzięki.

Więc utknąłem z tym przez chwilę.

SPRAWDŹ plik config/database.yml i sprawdź ustawienia.

default: &default 
    adapter: mysql2 
    encoding: utf8 
    pool: 5 
    username: root 
    password: root 
    socket: (check what your socket location is by typing mysqladmin version into termnal)

następnie przejść do terminala i wpisz

mysql -u root -p

a na końcu zamknąć terminal i ponownie otwarty, a potem

bundle instal

następnie

rails s

szwy jak masz ponownie zainstalować pakiet dla zmiany mają miejsce.

Nadzieję, że pomaga!

Jeśli zainstalowany przy użyciu pakietu Oracle, spróbuj zalogować się swoją mysql przez

mysql -u username

Następnie uruchom

FLUSH PRIVILEGES;

Następnie ustawić hasło

SET PASSWORD FOR 'username'@'localhost' = PASSWORD('[password]');
