Rails db：創建整理錯誤

Question

運行rake db：create時出現問題：

[root@zephyrnode /domain/rails/testapp ]# rake db:create --trace
(in /domain/rails/testapp)
** Invoke db:create (first_time)
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:create
Couldn't create database for {"adapter"=>"mysql", "encoding"=>"utf8", "collation"=>"utf8_bin", "reconnect"=>false, "database"=>"testapp_development", "pool"=>5, "username"=>"root", "password"=>"rootpass", "socket"=>"/var/run/mysqld/mysqld.sock", "host"=>"127.0.0.1"}, charset: utf8, collation: utf8_bin (if you set the charset manually, make sure you have a matching collation)

我已經在下面附上了所有可能的版本和設置信息。 我已經嘗試了所有在Google上找到的解決方案，但沒有運氣。 有沒有人有任何解決方案或建議？ 謝謝！

我的database.yml：

  adapter: mysql
  encoding: utf8
  collation: utf8_bin
  reconnect: false
  database: testapp_development
  pool: 5
  username: root
  password: rootpass
  socket: /var/run/mysqld/mysqld.sock
  host: 127.0.0.1

Answer 1

您是否嘗試過不指定排序規則？ 我使用utf8為我的MySQL數據庫指定編碼而不是歸類，它可以正常工作。

Answer 2

將database.yml文件中的排序規則行更改為以下任何show variables like "collation_server"; 。

然后嘗試rake RAILS_ENV=development db:create 。
