但是当我在 生产环境 服务器上运行'bundle exec rake db：create'时，我得到了不同的错误 .

我通过添加开发配置更改了 生产环境 服务器中的database.yml，并在'bundle exec rake db：create'时更改了另一个错误
deploy@akashpinnaka:~/akashpinnaka/releases/20170601052938$ bundle exec rake db:create
#<Mysql2::Error: Can't connect to MySQL server on '139.59.24.82' (111)>
Couldn't create database for {"adapter"=>"mysql2", "encoding"=>"utf8", "pool"=>5, "timeout"=>5000, "host"=>"139.59.24.82", "port"=>3306, "database"=>"akashpinnaka_website_development", "username"=>"akash", "password"=>"admin"}, {:charset=>"utf8"}
(If you set the charset manually, make sure you have a matching collation)
Created database 'akashpinnaka_website_development'
提前致谢！
