django.db.utils.OperationalError：致命：用戶“vagrant”的密碼驗證失敗

Question

我的 vagrant 盒子與端口和所有東西都有問題，所以我做了一些我懷疑會抑制我運行./manage.py migrate的事情。 這是我運行vagrant ssh-config時的樣子

HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile /Users/brock1hj/projects/sodium/to-vagrant/.vagrant/machines/default/virtualbox/private_key
IdentitiesOnly yes
LogLevel FATAL

這是完整的錯誤：

django.db.utils.OperationalError: FATAL:  password authentication failed for user "vagrant"

我真的不確定發生了什么，我認為用戶“vagrant”的密碼不知何故從默認的“vagrant”更改了。

我正在使用 Django 1.8.2

這是我的數據庫 settings.py 文件：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'vagrant',
        'USER': 'vagrant',
        'PASSWORD': 'vagrant',
        'HOST': '127.0.0.1',
        'PORT': '',
    }
}

我覺得它會嘗試將“vagrant”作為密碼，但情況不再如此。

嘗試進入 dbshell，提示輸入密碼以確保“vagrant”不起作用並得到：

Password for user vagrant:
psql: error: could not connect to server: could not initiate GSSAPI security context: Unspecified GSS failure.  
Minor code may provide more information could not initiate GSSAPI security context: Configuration file does 
not specify default realm
FATAL:  password authentication failed for user "vagrant"

Answer 1

嘗試：

1. vagrant ssh
2. psql
3. Then follow instructions on https://www.postgresql.org/docs/9.6/sql-alterrole.html , looks like you want ALTER ROLE vagrant PASSWORD 'vagrant';
